  • UPick Projects - Ecology or Biology - Students pick the projects they want to complete to earn points.  Each box can only be completed once, but they can do extra boxes to earn extra credit points.  I have included a list of vocabulary from our Ecology unit, which is also accessible on Quizlet.

  • Solve the Outbreak (CDC) - This website from the CDC provides 12 cases in Level 1 for students to investigate.  I divided them into 3 groups and had each student complete 4 of the cases.  After the activity, we discuss the results and shared our observations.  This activity was a great lead in for  a discussion on the influenza and coronoavirus.  Resources available include the student worksheet with teacher directions and the PowerPoint with instructions for the website and slides to facilitate the class discussion.

  •  Natural Selection & Peppered Moths- This lesson was to introduce and explore the concept of  natural selection.  The first activity has students watch an EDPuzzle video from the Ameoba Sisters to complete a note worksheet about natural selection in antibiotic resistance.  The second activity explores the Peppered Moths website, which includes background information and a game to challenge them to "eat" moths in two different forests. A digital version of this lesson is available as a Google Slide worksheet.

  • Waggle Dance Activity - The PowerPoint outlines the lessons I used during our Adaptations & Behaviors unit.  The activity gives students a "bees-eye" view of a hive and explains how they communicate. The activity also includes a game to challenge them to use the clues from various dances to find the correct flowers.  I also included a video that explains the waggle and round dances that helped them understand what to do during the game. A digital version of this lesson is available as a Google Slide worksheet.

  • The Organ Trail  - Challenge your students to create a "Wanted" poster about an organ. This download provides project guidelines, student information, and project worksheets.  Links for students can be found on the Health & Human Body links page of the Kid Zone.  

  • EDPuzzle - Ecology Basics - Students watch three videos on EDPuzzle to complete the notes. Each video includes a built-in quiz with question students must answer to continue watching.  If you have an EDPuzzle account (it's free), you can set up accounts for students to track their progress.  Reviewing the quiz responses will help you identify areas that need further instruction and learning activities.  Video links - Intro to EcologySerious Science: Biological Carrying Capacity, & Population Ecology (Mosquito Mystery)

Bug Blitz - A Study in Biodiversity (T. Tomm, Havana Junior High, Havana, IL)
Targeted Concepts:  Living things, classification, scientific investigations, process skills (observation, data collection, analysis, etc.), biodiversity

In past years our district had money for field trips to local nature areas for the Butterfly Brigade project; however, budget cuts made it difficult to pay for transportation.  I decided to adapt the project to a smaller level using our school garden, which is a quick walk to our front schoolyard!  I started this new project in the fall of 2016 as part of my Ecology unit for my 8th grade students.  The goal of project was to investigate biodiversity by documenting the bug populations that could be found there.   This project was a huge hit with the students - not only catching/documenting the bugs, but also implementing their strategies in the spring as we redid the school garden. This project could be utilized at any outdoor setting, such as state parks and local natural areas.

Microscope Mania (T. Tomm, Havana Junior High, Havana, IL)
Targeted Concepts:  Microscopes - history and uses, lab safety, classification (if using pond water)

After learning about the basic parts of a microscope and an overview of the proper procedures for using them, my students visit 5 lab stations to learn more about the world of microscopes. I allow at least 15-20 minutes per station and provide all the materials needed to complete the activities. Download the Teacher Notes below for a description of the station activities as well as a list of materials students need. Unit objectives and extension ideas are also provided.

NOTE: I developed this lab to deal with increasing class sizes and a limited amount of microscopes. Each year I found it challenging to teach microscope topics to 25+ students at a time with only 10 microscopes. With the stations, I am able to set up groups of 5-6 students and the students enjoy not having to share microscopes. I tend to focus my efforts on the groups at stations 3 & 4 as the others can be completed with little assistance from the teacher with the exception of a few visits to keep everyone on task.

Digital version coming soon!

Microscope Mania Unit Materials:

  • Teacher Notes (pdf) - Provides an overview of the unit as well as a description of the station activities and materials needed.
  • Station Cards (pdf) - Provides information cards for each station as well as materials for two review games - Parts & Pieces and Vocab Challenge.

Pond Water Survey (T. Tomm, Havana Junior High, Havana, IL)
Targeted Concepts:  Living things, classification, scientific investigations, microscopes, process skills (observation, data collection, analysis, etc.), food webs (if additional lesson is included)

An easy way to fascinate your students is to allow them to investigate samples of pond water (whether a large farm pond or small backyard pond.) They are sure to find little critters zooming around the slide. You will need to gather several samples (or have the students bring in their own), microscopes, and identification guides. Golden Guide publishes an inexpensive Pond Water booklet that contains lots of pictures and information. Follow-up discussions of finds will provide students with the chance to use biological terms to compare and contrast different forms of life. The updated version listed below includes additional lesson activities challenging students to create food chains using plants and animals found in or near a pond. It also includes templates for aquatic invertebrate trading cards.

A great resource for teachers with little biology background is to check with your local Department of Conservation or Natural History Survey. I was able to recruit a couple biologists along with their cool equipment and samples to work along with my students during class. My students were able to see organisms from the Illinois River and I loved having help in an area that I have little training.

A few years ago my district purchased a video flex microscope camera. Using this technology, my students are able to create a video documentary of our pond organisms. Each spring and fall we document our research and compare the changes that occur throughout the year.

Lesson Resources:

  • Pond Water Survey (pdf) - Contains teacher notes, discussion questions, and student worksheets.
  • Pond Water Webs (pdf) - Investigate food chains and webs that exists in a pond habitat. Download includes teacher notes, student worksheet, answer key, and Life in a Pond cards. A Power Point presentation is also available for use with interactive whiteboards.
  • Need identification guides? Visit the Pond Water Links page of the Kid Zone.

Lessons from the Lorax (T. Tomm, Havana Junior High, Havana, IL)
Targeted Concepts:  Environmental concerns, human impacts on the ecosystem, conservation, natural resources

At the end of our environmental science unit, my student explore the messages in the Lorax book and movie to identify environmental concerns and find ways to live a lifestyle with the smallest "footprint".  It also provides a great connection to the many topics we discuss related to deforestation, habitat loss, pollution, and human impacts on the Earth.

Students complete Part A of the student worksheet while watching the The Lorax Movie (1972 version) . We discuss the answers to Part B in class, and then we watch the newest version to respond to the question prompts in the Lessons from the Lorax PowerPoint.   The PPT includes an answer key and the discussion questions along with a follow-up activity.

Using my general EcoFootprint calculator, students complete the "footprint" with the different categories (page 2 of the download). They use the results to determine how many planets we would need if everyone lived like they do.  It is always an eye opening experience, which leads into the final lessons where they decorate the blank footprint with strateges they and their families will use to reduce their footprints. 

  • Lorax Lessons on FlipGrid - Students explain why the "Unless" quote is still important today and share two things they are doing to make the planet better. This lesson is incorporated into the challenge below.

  • Earth Day Challenge - I created this choice board assignment based on pasts Earth Day activities.  It has both Internet and non-Internet activities.  The FlipGrid lesson above is incorporated into the assignment as one of the choices.  Click HERE for a link to the Google Slides template you can copy to use with your students.

    NOTE:  I have also prepared a paper packet version for my kiddos who do not have Internet.  I will print copies to send home for those students. It includes "proof" pages similar to the Google Slides along with flash card templates, graph paper for a crossword puzzle, and other information they may need. I have a few copies of an old "Earth Day" booklet I plan to send home as I only have 10 students who need paper verions.

  • Also available ... My version of the Earth Day Challenge (Electronic option only)

    • I modified the basic one above to to create a new choice board (with hyperlinks built in) to include many of the online activities we have used in class - Quizlet, GimKit, Legends, and online tools (Poster My Wall, FlipGrid, video creators, etc.).  Clink THIS LINK to view it on Google Drive.

    • I also created an introduction video using a Google Slides presentation and Screencastify to review what we have learned and what I expect them to do for the project. 

    • Students will still use the Google Slides template to turn in proof for all completed tasks.  It will be shared with the students on Google Classroom by choosing "create a new copy" for each student.

Hydra Investigation (T. Tomm, Havana Junior High, Havana, IL)

During this lab activity, students observe the characteristics of life as they complete the lab worksheet. I adapted the basic lab found in a previously used textbook to include an information section. Students will need to use various reference sources and deductive skills to fill in the blanks.

For this activity (which takes one class period) you will need microscopes, depression slides, toothpicks, fish food, vinegar, and a supply of hydra (available through science supply companies for a small amount of $$). I use a small eyedropper to get the hydra from the vial to the slide - one slide for 2 to 3 students.

Student Worksheet: Hydra Lab

Worksheet Answers:
Part A: 1. jellyfish, 2. Cnidaria,3. cells, 4. tentacles, 5. ponds, 6. streams, 7. ingest, 8. excrete, 9. stinging, 10. paralyze, 11. creeping, 12. looping, 13. regenerate, 14. tissue, 15. organism, 16. multicellular, 17. hermaphroditic, 18. sex cells, 19. budding, 20. separate

Part B: Step 1: Check diagrams and labels; Step 2: Hydra will “draw” in its tentacles or possibly attach to toothpick, Step 3: Hydra will move towards the food and “nibble” on it.

Part C: Various answers might include movement, metabolism (ingestion, excretion), reproduction (if buds are present), and responds to environment.

Classification Challenges (T.Tomm, Havana Junior High, Havana, IL)
Targeted Concepts:  Living things, classification, binomial nomenclature, invertebrates, vertebrates

I designed this activity to allow students to practice invertebrate and vertebrate classification using the organisms discussed in our Animal Classification unit. Teacher notes, student worksheets, and organism cards are included in the downloades listed below. You will also need the classification mats, which needs to be printed regular-sized paper and taped together to form one mat.

Incredible Cells (T. Tomm, Havana Junior High, Havana, IL)
Targeted Concepts:  Living things, cells (plant and animal), organelles and their functions

The "edible" version of this project was an annual favorite was adapted from the old Jello cells! The project is a great addition to any cell unit and provides a tasty treat for your students. Refer to the Student Worksheet below for details and instructions. The download also includes a student worksheet for a nonedible cell project. If I have any students with food allergies, I require everyone to do the nonedible version.

Construction Zone (T. Tomm, Havana Junior High, Havana, IL with inspiration from Stacy Baker)
Targeted Concepts:  Living things, cells (plant and animal), organelles and their functions

This project was created for 5th grade students at my school to give them an "inside" view of a cell. Students work as construction teams to build a 3-D model of a cell. They are required to label the organelles with names and functions. Students have used PVC pipe for frames or obtained large boxes from our local appliance store. Students also use the sites on the Biology page of the Kid Zone and their textbooks to research the organelles.

Student Worksheet: Construction Zone (pdf)

 

Classroom Cell (T. Tomm & C. McDaniel, Havana Junior High, Havana, IL)
Targeted Concepts:  Living things, cells (plant and animal), organelles and their functions

Print out the Classroom Cell necklaces and assign "jobs" to the students that mimic the organelles' jobs in the cell.  For example, the teacher would be the nucleus who directs that activities of the cell, while a student that is a lysosome would help "clean up" the classroom each day. Our 6th grade teacher uses this activity and I refer back to it while discussing cells and organelles in our 7th & 8th grade lessons.  It is one of the lessons they remember!

Mitosis Flip Books (T. Tomm, Havana Junior High, Havana, IL)
Targeted Concepts:  Mitosis, cell division, organelles and their functions

This project (passed down to me from a fellow teacher) is based on the old cartoon flip book idea. Students use template cards (printed on cover stock or glued to index cards) to create a booklet that illustrates the steps involved in cell division. After reviewing the stages in cell division (see the Mitosis Note page below), I provide a set of templates (see Mitosis Book below) for them to use to make a flip book. From phase to phase, they must draw diagrams to show the changes that occur throughout the process. I encourage "color coding" to make the end effect easy to follow. Once all the Pages are completed and in the correct order, students use a heavy duty stapler to bind them together. They can flip through the pages and "see" mitosis in action.

Genetics with a Smile (T. Tomm, Havana Junior High, Havana, IL)
Targeted Concepts:  Living things, genetics, inherited traits, genotype, phenotype, dominant/recessive

During this activity students use pennies to determine the traits for a smiley face, then use Microsoft Word to create the smiley face. After students have completed the faces, I display them in the classroom and have students use their knowledge of genetics to answer questions about smiley faces, traits, and probability.

Student Worksheets:

A few of the smiley faces created by my students!

Other ideas to try...
•  Connect with another classroom and share your results with them! Challenge students to summarize the similarities and differences between the smileys created in your school and those at your partner school.
• Challenge your students to pair up two smileys as "new" parents and then flip a penny to determine the traits for a new baby. The students can then draw the baby smiley and compare the results to the parent smileys. (Thanks to Nancy Nega for this great idea!)
• Another twist for the new baby idea - instead of making just one baby, have the students create a display that shows the possible outcomes if two smileys had a baby. Students can provide expected rates of occurrence for each trait based on the parent's traits and compare those to the results of their classmates.

Egg-cellent Ideas for Osmosis and Diffusion (Submitted by Sue Remshak, Lake Bluff Middle School, Lake Bluff, IL)
Targeted Concepts:  Cell processes, osmosis, diffustion, science process skills (observations, hypothesis, data collection, analysis)

During this activity students investigate the concepts of osmosis and diffusion using eggs. To prepare for the activity, have students carefully measure and record the circumference of the raw egg as well as its mass. Place the egg in a beaker filled with white vinegar and allow time for students to record their observations. Store the eggs in a refrigerator for 24 hours. Allow time for students to record their observations. Return the egg to the refrigerator for another 24 hours. After 48 hours have elapsed, observe the egg's appearance. Students should carefully remove the egg from the beaker and record its measurements. Allow time for students to write an explanation of their observations using the correct vocabulary.
Teacher Info: A chemical reaction occurs between the vinegar and the calcium carbonate in the egg shell. The bubbles of carbon dioxide that form on the egg and rise to the surface are evidence of this reaction. The shell dissolves in the vinegar and leaves a film on the surface of the vinegar. However, the membrane remains on the egg. The size of the egg increases because of the movement of water in the vinegar through the cell membrane. Since water moves from an area of high concentration to an area of low concentration, this process is called osmosis. Obviously, none of the materials on the inside of the egg are able to pass through the membrane.

For the second portion of the activity, you will need plain water, blue water (food coloring in water), molasses, and corn syrup. First, have the students determine the mass of the egg and record it in the table. They should pour 150 ml of each substance into its own beaker. Add the eggs and store in a refrigerator for 24 hours. After 24 hours, have the students remove the eggs from the beakers and record their observations. Students should record the volume of liquid in the beaker as well as the mass of the egg. Finally, have the students use a toothpick to pop the egg membrane and record their observations. Be sure to have paper towels handy as some eggs may squirt!) Allow time for students to write an explanation of their observations using the correct vocabulary.
Teacher Info: The egg in plain water and blue water will become slightly larger because water will pass into egg through the membrane by the process of osmosis. There will be blue food coloring in the egg from the blue water since both water and food coloring can pass through the membrane. The egg in corn syrup and molasses will decrease in size because water from inside the egg flow through the membrane into the syrup or molasses. It moves from a higher concentration inside the egg to a lower concentration in the corn syrup. Once again, this is called osmosis. The corn syrup and molasses molecules are too large to pass through the membrane. Observant students will not only notice an increase of volume in the beaker, but they will also see a thin layer of water resting on top of the syrup and molasses.

To illustrate the concept of diffusion, add a drop or two of extract (vanilla, bubble gum, lemon, or cinnamon) into a deflated balloon. Blow up the balloon, tie it off, and place inside a shoe box. To make sure the lid stays on the box, use masking tape to secure it. During class, ask students to life one end of the shoe box lid and smell the contents. Their eyes should remain closed when they do this. Ask each student to reveal what they smelled. Show the class what was inside the box and instruct them to draw a picture and record their observations. Challenge students to write an explanation (using the correct vocabulary) of why the box smells like the scent when it was only put inside the balloon.
Teacher Info: The shoe box smelled of the scent even though it was only placed on the inside of the balloon due to the process of diffusion. Every balloon has microscopic holes in its surface. The vapors were able to pass through the membrane from an area of high concentration to an area of low concentration. However, the liquid scent molecules were too large to pass through the membrane.

Another way to illustrate osmosis and diffusion is using a tea bag and some water. During class, place a tea bag in a beaker of warm water. Allow time for students to record their observations. Challenge them to write an explanation using the correct vocabulary.
Teacher Info: Water flows by osmosis into the tea bag. The students can see this if you remove the tea bag from the beaker and squeeze it to see the water come out. The tea leaves diffuse through the tea bag and into the water; this changes both the color and flavor of the water in the beaker.
