Introduction To Insect & Spider Body Parts
Students inspect several different specimens of insects and spiders to determine characteristics that are similar and different between the two groups. They identify the basic body structure of spiders and insects and then predict where...
Curated OER
Temperature and Brine Shrimp Eggs
Students determine the optimal temperature at which brine shrimp eggs hatch and develop. They evaluate the changes, if any, which occur in a brine shrimp culture at various temperatures.
Curated OER
Barnacles: Harder than Cement
Fourth graders watch the movements of the complex animal hidden inside the tiny barnacle shells. This lesson allows students to study the behavior, adaptation, and larval stage of the barnacle.
Curated OER
pH Change and Brine Shrimp eggs
Students determine if brine shrimp eggs hatch and develop more readily in an environment which has an acid or a basic pH. They evaluate the pH level which is optimal for the hatching and development of brine
shrimp.

Comparative Embryology Using Japanese Medaka Fish
Students conduct an experiment to control the breeding of Japanese Medaka fish. They collect the fertilized eggs and view and record the fish's embryological development daily to compare the stages to human development.
Curated OER
Plant Life
Seventh graders examine different categories of plant life and their roles as producers of food and oxygen for other organisms. They study the evolution of plants from simple organisms to very complex ones. They look at the different...

Collect Your Own Drosophila Lab
Learners study Drosophila by catching them. They construct catcher-containers to catch Drosophila using fruit as bait. After collection, they examine the flies and collect data to be displayed.
Curated OER
Hormone-Induced Plant Propagation Lab using Carrot Root Cultures
Students evaluate the importance of hormones in living things. In this biology lesson plan, students experiment on carrots to differentiate how humans and plants reproduce. They collect data from experiment to answer analysis questions.
