In this activity, learners use tsunami time travel maps to predict how long it will take a tsunami to reach the shore.

This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

In this activity, learners create models of ionic compounds and observe the chemical formula of binary molecules they have created.

In this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

In this activity, learners create and experiment with wind tubes. These tubes are a playful and inventive way to explore the effect that moving air has on objects.

Learners will follow a specific process to make their own paper using scrap paper, newspaper, or junk mail.

In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.

In this activity, learners use microarray technology to determine which genes are turned on and off at various points in the differentiation of pluripotent stem cells on their way to becoming pancreat

Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).

Cardboard Automata are a playful way to explore simple machine elements while creating a mechanical sculpture.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

In this activity, learners design a scientific exploration mission to a planet or moon of their choice.

In this activity, learners observe fly behavior and then build a flytrap.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.
