Engineer an Aeolipile
Source Institutions
In this engineering design challenge, learners build an air-powered spinning machine.

Root Beer Float
Source Institutions
In this quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.

Toad Toy
Source Institutions
In this activity, the learner will explore hand eye coordination while using a variation of the ball and cup game.

Ice Fishing
Source Institutions
In this activity, learners will use string and salt to lift an ice cube out of a glass of water. Salt depresses the freezing point of water, allowing it to melt around the string and refreeze.

Leaf Rubbings
Source Institutions
When was the last time you took a really close look at a leaf? In this activity, learners will use leaves and simple materials to make colorful leaf rubbings.

Spinning Blackboard
Source Institutions
Create beautiful spirals by drawing a straight line. This sounds crazy, but you can with a turntable (a record player or lazy susan), paper, and pen.

Making Music in Nature
Source Institutions
In this activity, learners will explore the ways natural materials can produce sounds. Appropriate for any age, learners can make individual music or create a symphony with others.

Exploring Size: Tiny Ruler
Source Institutions
In this activity, learners investigate just how small a billionth of a meter is by attempting to cut a paper ruler down to a nanometer-sized sliver.

Exploring the Universe: Space Guess Quest
Source Institutions
Space Guess Quest is a fun game that encourages participants to identify the many types of objects in space, from human-made spacecraft to nebulas, galaxies, stars, and worlds.

Exploring Materials: Hydrogel
Source Institutions
In this activity, learners discover how a super-absorbing material can be used to move a straw.
Soaring Towers: Building with Recycled Materials
Source Institutions
In this activity, learners will build the highest tower they can out of recycled materials.

Twelve at a Time
Source Institutions
As learners play this game, they build skills in area, perimeter, multiples and factors. They take turns making rectangles with 12 squares on the grid.

Morning Star and Evening Star
Source Institutions
This demonstration activity models how Venus appears from Earth.

Egg-Citing Physics
Source Institutions
In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open.

Pollinator Bath
Source Institutions
In this activity, learners will build a design and build a place for pollinators to drink from.

Amphibian Skin
Source Institutions
In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

Watch and Create! Creativity For Sustainability
Source Institutions
In this activity, children and adults work together to explore their relationship with technology and examine ways to make sustainable media consumption choices.

Secret Message
Source Institutions
In this activity, learners explore acid and bases as they create their own invisible ink out of baking soda and grape juice.

Homemade Bath Fizzies
Source Institutions
In this activity, learners make their own bath bomb fizzies and experience what happens when they mix a base and an acid.
