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 observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

In this physics activity, challenge learners to lift a book with just air using a plastic bag and a straw. This activity demonstrates compressed air and forces.

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.

The Drawing Board consists of a marking pen that remains stationary and a platform that swings beneath the pen, acting as a pendulum.

In this activity, learners explore chemical engineering and how the processes of chemical plating and electroplating have impacted many industries.

In this activity learners will build roller coasters and test them using small balls or marbles.

“Exploring Earth: Rising Sea” is a hands-on activity demonstrating ways to use topographical mapping techniques to track changes in sea level. The activity is connected to current NASA research.

In this activity (page 2 of PDF under GPS: Alligator Habitat Activity), learners will study the adaptations different fish species have developed to survive in their habitats.

In this activity, learners explore the concept of force and how pulleys are used in everyday life to make work easier.

In this activity (page 18 of PDF), learners will measure the volume of impact craters created by projectiles of different masses.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

In this chemistry activity, learners witness an exothermic reaction, while making their very own, completely usable sidewalk chalk. This is also an excellent activity for exploring color mixing.

The demonstration/experiment provides quick proof that air has mass.

In this activity, learners will first learn the basics of galaxy classification and grouping.

In this activity, learners explore density, convection, stratification, and, by inference, the melting of icebergs. Learners make hypotheses, test their hypotheses, and explain their observations.

In this activity, learners conduct an experiment to test how fast they can react. Learners try to catch a piece of paper with a ruler printed on it (or a ruler) as quickly as they can.

Birds' beaks are designed to allow birds to get the most of whatever food they need. In this activity, learners get an idea of how different beak shapes suit different food sources.

In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.

In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.
