In this mechanical engineering activity, learners design shadow puppets with moving parts and use them to tell stories.

Learners make self-assembled polymer spheres as a model for the lipid nanoparticles found in COVID-19 mRNA vaccines.

In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

Learners observe working lava lamps to understand how they work (included in PDF link).

In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.

In this activity, learners test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

In this outdoor activity, learners use artificial bees and paper models of flowers to find out how bees transfer pollen from one flower to another.

This series of chemistry stations is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Each of the six stations features either a chemical or p

This activity was designed for blind learners, but all types of learners can explore the process used to cast and mold molten metal, glass, and plastics.

Learners place their hands on different metals and use an ammeter to monitor the flow of electricity from one metal to another.

In this activity, learners investigate the sense of hearing and plan and conduct their own experiments.

In this activity, learners discover how NASA engineers develop experimental aircraft.

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.

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

This demonstration can be used to help learners visualize DNA by lysing (breaking open) bacterial cells on a slide and “stringing up” the DNA with a toothpick in less than one minute.

In this activity, learners help identify native and non-native plant species, learn about invasive species, and determine how native plants provide a healthier habitat.

In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.
