In this outdoor activity, learners design devices that will catch prey or gather plants.

In this activity, learners perform an experiment that replicates the dilemma faced by birds in acquiring food from a confined area.

In this activity, learners investigate the food, water, and space needs of common livestock animals.

In this activity, learners are challenged to eat some candy as a cell would need to as well as to think about some of the problems that arise when a cell ingests food.

This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.

In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.

In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this math lesson, learners apply the concepts of ratio and proportion to the capture-recapture statistical procedure.

This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi

In this activity, learners use a model for how fishing affects marine life populations, and will construct explanations for one of the reasons why fish populations are declining.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.
