In this Cyberchase activity, learners play a simple game using 15 paper dragons (or any 15 objects). One of the 15 dragons is red. Learners try to make their opponent take the red piece.

This is a series of three quick science activities to do with a spoon, knife, and fork. In the first two activities, learners use the flatware to explore optics, mirrors, reflection, and distortion.

In this online activity exploring our perception of "cuteness," learners adjust various factors (like pupil size or length of limbs) on a face, a cat, and a hammer.

In this activity, young learners (2 years and up) explore turtle basic adaptations and biology. Turtle external anatomy is explored by "building" a turtle with a nature collage.

In this activity, learners compete in a game to cover the most area by drawing randomly-generated rectangles on graph paper.

“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, learners discover that it is difficult to trace a curve by using its reflection in a mirror. Use this activity to discuss how the brain works.

In this activity, learners heat ice and water of the same temperature to get a hands-on look at phase changes. This is an easy and inexpensive way to introduce states of matter and thermodynamics.

Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.

In this weather activity/demonstration, learners watch as a ping pong ball is suspended in a stream of air supplied by a hair dryer.

In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.

In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

In this a hands-on activity, learners explore how to put ice cream in an oven without it melting. Ideas in this activity include insulation and cooking.

In this activity, learners explore materials through paper chromatography.

In this activities, learners head outside and investigate trees through bark rubbings. Learners will need paper, a pencil, and some unwrapped crayons to create them.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

In this chemistry activity, learners explore density by using four solids and 6 liquids to create colorful, layered rows.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

In this demonstration, learners observe vinegar and baking soda creating carbon dioxide (CO2) in a bottle. The gas is poured out of a bottle onto a candle flame, putting out the candle.
