Density: Make a golf ball float!
Source Institutions
In this activity (on page 2 of the PDF), the learner places a golf ball between salt water and colored fresh water. The golf ball is not as dense as the saltwater.
It's a Gas!
Source Institutions
In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.
Gas Production: Blow up a balloon!
Source Institutions
In this classic reaction, learners baking soda and vinegar in a soda bottle to produce carbon dioxide (CO2) gas. This gas inflates a balloon.
Rocket Reactions
Source Institutions
The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.
Glow Fast, Glow Slow: Alter the Rate of a Reaction!
Source Institutions
Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.
The Amazing Water Trick
Source Institutions
Using two baby food jars, food coloring, and an index card, you'll 'marry' the jars to see how hot water and cold water mix.
Dancing Spaghetti
Source Institutions
In this chemistry activity, learners use spaghetti to explore density and chemical reactions.
Peanut Butter and Jelly Robot
Source Institutions
This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.
Diving Submarine
Source Institutions
Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.
Chemical Reactions in Your Mouth
Source Institutions
In this chemistry activity (page 5 of the PDF), learners will see that chewing is more than just the crushing up of food; there is actually a chemical change going on at the same time.
Miscibility
Source Institutions
Learners observe a bottle containing water and oil. They are invited to pick up the bottle and mix the contents together.
Color Splash
Source Institutions
In this activity, learners mix water, cooking oil, and liquid food coloring to create beautiful colored designs in a cup. Use this activity to explore liquid density and solubility.
Reaction Time
Source Institutions
In this activity, learners conduct an experiment to test how fast they can react. Learners try to catch a piece of paper with a ruler printed on it (or a ruler) as quickly as they can.
Pepper Scatter
Source Institutions
In this quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract
Balloon in a Bottle
Source Institutions
In this physics activity (page 3 of the PDF), learners will see firsthand that air takes up space and has pressure by attempting to inflate a balloon inside of a bottle.
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.
Layered Liquids: Chemistry You Can Drink
Source Institutions
In this chemistry activity (on page 2 of the PDF), learners make a layered drink with liquids of different densities.
Daffy Density
Source Institutions
In this chemistry activity, learners explore density by using four solids and 6 liquids to create colorful, layered rows.
Why Are Two Eyes Better Than One?
Source Institutions
In this activity, learners explore how their depth perception would be affected if they only had one eye. Learners work in pairs and attempt to drop a penny in a cup with one eye covered.
Fizzy Fun
Source Institutions
In this activity, learners test what happens when they put baking power on different frozen liquids.
