Draft Detectives
Source Institutions
In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.
Why Doesn’t the Ocean Freeze?
Source Institutions
In this activity, learners explore how salt water freezes in comparison to fresh water.
It's a Gas, Man
Source Institutions
In this activity, learners discover if carbon dioxide has an effect on temperature.
Temperature Time Warp
Source Institutions
In this activity, learners explore the behavior of cold-blooded animals. Learners discover what happens when they change a fly's temperature.
Crunch Time
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.
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.
Hot Air Balloon
Source Institutions
In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.
Change in Temperature: Endothermic Reaction
Source Institutions
Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.
Wonderful Weather
Source Institutions
In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.
Energetic Water
Source Institutions
In this activity, learners explore how hot and cold water move. Learners observe that temperature and density affect how liquids rise and fall.
Keep-a-Cube
Source Institutions
In this activity, challenge learners to keep an ice cube from completely melting in 30 minutes. Learners engineer a box or wrap to prevent an ice cube from melting.
Condensation
Source Institutions
In this activity, learners explore the process of condensation.
Pickle Lab
Source Institutions
In this online activity, learners experience the thrill of pickle making, and explore how a cucumber becomes a pickle.
Magical Match
Source Institutions
In this demonstration, learners will be "wowed" as three matches burn to form a triangular pyramid shape and "magically" rise off the table.
If Anyone Can, Icon
Source Institutions
In this activity, learners create their own icons for a forecast-at-a-glance poster for their classroom/learning space.
Vibrating Pennies
Source Institutions
Conduct a simple experiment to explore how temperature changes can make things expand or contract.
Do Sweat It!
Source Institutions
In this activity, learners explore why humans sweat. Learners compare the effects of heat on a balloon filled with air and a balloon filled water.
Temperature Affects Dissolving
Source Institutions
Learners design their own experiment to compare how well cocoa mix dissolves in cold and hot water. They will see that cocoa mix dissolves much better in hot water. Adult supervision recommended.
What's in the Water
Source Institutions
"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?
