In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

In this lab (Activity #1 on page), learners explore how we see color.

In this data activity, learners analyze data from coral reef snapshots taken by scientists at the Virginia Institute of Marine Science.

This laboratory activity helps learners understand the concept of biological succession by simulating the process in a microenvironment with various protozoans.

This activity helps students learn how computers "compress" text by identifying repeating patterns of letters, words, and phrases.

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

In this activity, learners listen to songs and decode hidden messages based on the same principle as a modem. As a final challenge, learners decode the binary messages in a music video.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this activity, learners play a series of simple games to investigate navigation without visual and sound cues.

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

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 explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

This magic trick is based on how computers detect and correct data errors.

Get a roll of pennies, throw them on the ground, then remove those that only show tails, and repeat with the ones left over.

In this genetics activity, learners create and decode a “DNA recipe” for a dog by randomly selecting strips of paper that represent DNA.

In this activity, learners explore accuracy and precision.

In this activity, learners create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

Learners will do an experiment to determine which type of paper is strongest while focusing on variables and collecting data.

In this activity, learners explore the devices used over time to measure changes in temperature.
