Burn a Peanut
Source Institutions
In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut.

Design a Flavor: Experiment to Make Your Own Ice Cream Flavor!
Source Institutions
In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.

Pie-Pan Convection
Source Institutions
It's difficult to see convection currents in any liquid that's undergoing a temperature change, but in this Exploratorium Science Snack, you can see the currents with the help of food coloring.

Bake Ice Cream in Your Oven
Source Institutions
In this a hands-on activity, learners explore how to put ice cream in an oven without it melting. Ideas in this activity include insulation and cooking.

Geyser
Source Institutions
This Exploratorium activity can be used in many contexts because geysers are great opportunities for learning about heat and temperature changes as well as geological/space science phenomena.

Nano Ice Cream
Source Institutions
In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

Get the Porridge Just Right
Source Institutions
Learners set up three different bowls, each with a different mass of oatmeal. Learners monitor the temperature of the oatmeal and find that larger masses take longer to cool.

Solar Powered Cooking
Source Institutions
In this activity, learners make a solar oven. Learners witness the awesome power of the sun to make a yummy treat--a chocolate chip cookie!

Can You Make Ice Cream in Two Minutes?
Source Institutions
In this demonstration, learners observe how liquid nitrogen both boils and freezes ingredients to make ice cream in two minutes.

Conduction Countdown
Source Institutions
In this quick SciGirls activity (page 1 of the PDF under SciGirls Activity: Doghouse Design), learners will be introduced to the concept of thermal conductivity.

Solar Cooker
Source Institutions
Learners build a simple solar oven from a shoebox, black construction paper, and aluminum foil. Over the course of a few hours, the oven heats up water enough to brew tea.

Cool It!
Source Institutions
In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!

Solar Convection
Source Institutions
In this activity, learners add food coloring to hot and cold water in order to see how fluids at different temperatures move around in convection currents.

Ice Cream Shake
Source Institutions
In this tasty activity, learners make their own ice cream any day of the year in an exploration of heat and cold. Highlights include freezing and melting and the transition from liquid to solid.

Reflective Solar Cooker
Source Institutions
In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.

Melts in Your Bag, Not in Your Hand
Source Institutions
In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

Frozen Fruit
Source Institutions
In this "Sid the Science Kid" activity from Episode 108: My Ice Pops, learners observe reversible change while thinking about ways to make ice melt.

Pot-in-Pot Refrigeration
Source Institutions
In this activity (on page 2 of PDF), learners create a low-tech refrigerator that requires no electricity to keep food from spoiling.

Cook with a Solar Oven
Source Institutions
In this activity, learners make their own solar oven to bake s'mores and learn about how solar energy is absorbed on Earth.

Keep it Cool
Source Institutions
In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.
