In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

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.

Build and test a scale model of a rainforest canopy walkway.

In this activity, learners explore the "nuts and bolts" of gene chips.

In this 6-7 day investigation, learners begin with an introduction to seamounts that are present in the Gulf of Alaska.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

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

In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit

In this activity, learners identify the DNA base bars guanine, cytosine, thymine and adenine. Learners create a DNA model using colored paper clips to resemble these base pairs.

In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete
