In this activity, learners explore how the hull shape impacts a ship's performance and stability.

In order to examine the random nature of mutations and natural selection, learners "breed" clutches of Egyptian Origami Birds (Avis papyrus) using random number generators (dice and coins) to mutate s

In this activity, learners will examine a variety of seeds, describe them, and determine how they are dispersed.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this activity, learners explore accuracy and precision.

In this activity, learners apply Ohm’s Law to construct voltage divider circuits. Learners discover how to read resistor codes and calculate resistor values.

In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.

In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.

In this activity, learners explore how boats are engineered to achieve speed.

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 build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.

In this activity, learners are divided into teams.

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

This is a lesson plan for an activity in which learners, playing the role of archeologists, use math concepts about number bases to decipher the Dresden Codex, an ancient Mayan document.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.
