Nuclear Popcorn
Make your lesson on radioactive decay pop with this lab exercise. Using popcorn kernels spread over a tabletop, participants pick up all of those that point toward the back of the room, that is, those that represent decayed atoms. As the...

The Effects of Water Quality on the Growth Rate of Freshwater Mussels
Students participate in a field and laboratory study to determine if local freshwater mussels are environmentally stressed.
Curated OER
Cave Formation Age Estimation
Students investigate growth rates of flowstone formations. They view a virtual field trip and discuss how flowstones form. They observe the cave fieldtrip and predict the growth rate for a cave formation. They graph growth rates and...

The Circulatory System - Part IV
First graders explore the heart muscle. They discover that the heart beats faster during exercise. Students locate their heart with a stethoscope and imitate the sound their heart makes. Students locate their carotid pulse before and...
Curated OER
Circulatory System
Students rotate through various physical activities checking their carotid pulse after each. This activity will give knowledge to students about health behaviors and understanding the exercise aspect of growth and development.
Curated OER
Pulse
Students determine a baseline pulse rate then chart the changes in rate with exercise. They describe the changes and develop a rationale for their observations. The task assesses students' abilities to make simple observations, determine...
Curated OER
Studying Plant Development Through Metabolic Activity
A hands-on activity which allows young scholars to learn about cellular respiration. This lesson contains a range of investigations testing the rates of cellular respiration to demonstrate the relationship between metabolic rates of...
Curated OER
Keeping Healthy
Students exercise their muscles to explore concept of heart rate and to explain how blood supplies muscles with oxygen.
Curated OER
Scientific Notation III: Linear vs Exponential
Students examine the differences in exponential growth and linear growth of a system. They interpret data on graphs and develop their own charts. They answer discussion questions as well.
Curated OER
Water Management
Students investigate the plan of a community water management plan. They are given the roles of community members who are involved in a meeting to discuss the development of a plan to conserve water and preserve resources of water.
Curated OER
Fracture Fundamentals: A Cheesy Analog
Young scholars make small cuts (fracture nuclei) in processed cheese food and then apply stresses perpendicular or parallel to the cuts to see how fractures grow. They make predictions before each experiment and explain their results to...
Curated OER
The Night Tree
Second graders explore the book, Night Tree, by Eve Bunting. They read and discuss the story, identify what the tree did for the animals, create a food chain for animals to hang on a tree, and decorate a tree at school.
