A Funny Taste
Source Institutions
In this activity, learners explore the different salinities of various sources of water by taste-testing.
Rotating Light
Source Institutions
In this activity, learners explore what happens when polarized white light passes through a sugar solution.
Diet Light
Source Institutions
In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.
Amazing Marshmallows
Source Institutions
In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.
Egg Drop
Source Institutions
Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.
Pepper Scatter
Source Institutions
In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.
Fuel for Living Things
Source Institutions
In this activity, learners observe what happens when yeast cells are provided with a source of food (sugar). Red cabbage "juice" will serve as an indicator for the presence of carbon dioxide.
Potato Power
Source Institutions
Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.
What's the Difference between Weather and Climate?
Source Institutions
In this interactive and informative group activity, learners use packages of M&M's to illustrate the difference between weather and climate.
The Nose Knows
Source Institutions
In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.
Potato Straw
Source Institutions
In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.
Red, White and Blue II Demonstration
Source Institutions
In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.
Erupting Fizz
Source Institutions
This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.
Marshmallow Puff Tube
Source Institutions
In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.
Powder Particulars
Source Institutions
In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.
Soda Pop Cave
Source Institutions
In this geology activity (page 6 of the PDF), learners explore how carbonic acid can slowly dissolve limestone and form caves.
Finding the Carbon in Sugar
Source Institutions
In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.
Gelatin Optic Fibers
Source Institutions
In this activity, learners make optical fibers out of strips of gelatin.
Triboluminescence
Source Institutions
In this activity, learners discover what happens when they crush wintergreen-flavored candies in a very dark room.
Changing the Density of an Object: Adding Material
Source Institutions
Learners see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float.
