Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.

In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

In this invention challenge activity, learners create an indoor game for one or two people that gets you moving.

In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this activity, learners design a therapeutic agent to image and/or cure various diseases in the respiratory system.

This game uses a modified Uno deck to review concepts related to stem cell research and diabetes.

In this activity, learners test and compare the physical properties of thermoplastic polymers. Learners compare different plastics based on their color, degree of transparency, texture, and density.

This activity lets learners participate in the process of reconstructing a phylogenetic tree and introduces them to several core bioinformatics concepts, particularly in relation to evolution.

In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

In this game (on pages 14-21), learners explore how each human being inherits genetic traits such as eye color.

In this activity, learners use maps to locate the Arctic region and use a word game to discover the types of resource people need to survive in the extreme climate.
