One In The Hand
Source Institutions
In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.
Invisible Sunblock
Source Institutions
In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.
Shrinky Dinks
Source Institutions
Heat makes some materials expand, and it makes others shrink.
Exploring Materials: Ferrofluid
Source Institutions
In this activity, learners discover that a material can act differently when it's nanometer-sized.
Reflections
Source Institutions
In this activity, learners play a game and use pattern blocks to explore mirror images and reflection.
Upside-Down Town
Source Institutions
In this activity, learners explore ray optics. Learners discover that they can use a magnifying glass to create an upside-down image.
River Catcher
Source Institutions
In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.
Toasty Wind
Source Institutions
In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.
Changing Colors
Source Institutions
Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.
Flower Power
Source Institutions
In this activity, learners will experiment with changing flower colors. Learners will investigate the effects of acids and bases on flower colors.
Bark Beetle Infestation Investigation: Estimation and Pheromones
Source Institutions
This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.
Go With the Flow
Source Institutions
In this activity, learners will observe laminar and turbulent flow of water using only a plastic bottle, liquid hand soap, food coloring and water.
Water Drop Races
Source Institutions
In this activity, learners will explore the physics of liquids and gas by playing with both! Learners of any age use their own breath to move drops of water across a smooth wax paper surface.
Sink or Float
Source Institutions
In this activity, learners explore and compare the buoyant properties of materials found in nature and in human-made materials.
Rocket Pinwheel
Source Institutions
This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.
Hot and Cold
Source Institutions
In this activity, learners explore temperature changes from chemical reactions by mixing urea with water in one flask and mixing calcium chloride with water in another flask.
Save a Snowman
Source Institutions
In this activity, learners explore the concept of insulation by trying to keep Olaf the Snowman from melting. This activity encourages critical thinking and problem solving.
Lego Mania
Source Institutions
In this activity, learners will put together towers using building bricks, then take the tower apart and challenge themselves to use the same bricks used to build a bridge.
Wet Art
Source Institutions
In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.
That's the Way the Ball Bounces: Level 1
Source Institutions
In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.
