In this activity, learners discover a brain process called habituation.

In this "Sid the Science Kid" activity from Episode 109: The Perfect Pancake, learners make applesauce to explore irreversible change.

In this game, learners cutout a model black hole "cone" and attempt to roll around a marble or other small spherical object without touching the event horizon.

In this activity, learners will experiment with different materials that can melt and change ice.

In "Chemistry is Colorful" learners explore different materials through paper chromatography.

In this activity (3rd on the page), learners conduct a series of tests to find out which of their eyes is more dominant.

In this activity about transfer of energy, learners get to build their own catapult using nothing more than a plastic spoon and some tape.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.

Learners describe objects in a room using only numbers and shapes. They can measure the object (like a desk) and make a list of facts about it (e.g.

In this online game, learners must purchase power plants for their city.

This activity is a whole-group kinesthetic demonstration that shows learners what it means to be in a "risk group" for developing heart disease based on family history and genetics.

In this simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.

In this activity, learners will take a walk with their family and incorporate a scavenger hunt. They will explore topics like ABC’s, numbers, colors, and shapes as they search for related items.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

In this activity, learners observe mixtures of sand samples glued to note cards, and consider how sand can differ in size, shape, and color, and where it comes from.

In this activity, learners will make and launch feather rockets. Lerners will use science process skils such as making predictions and measuring while launching the rockets.

In this engineering activity, challenge learners to build a tower out of 10 sheets of newspaper and 3 feet of masking tape, which can hold a golf ball balancing at the top.

In this activity, learners develop spatial reasoning skills as they blow bubbles and observe what happens when the bubbles connect.
