Heating and Cooling of the Earth's Surface
Source Institutions
Learners conduct an experiment to determine the rate at which two materials, sand and water, heat up and cool down.
Illuminations on Rates of Reactions
Source Institutions
In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.
Insulation Station
Source Institutions
In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.
Easy PEAsy Seed Germination
Source Institutions
In this activity, learners determine the necessary conditions for pea seed germination.
Moldy Jell-O
Source Institutions
In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.
Cooling Off
Source Institutions
In this activity, learners are introduced to challenges of maintaining temperatures while living in space.
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.
Liquid Crystal Thermometers
Source Institutions
In this activity, learners explore liquid crystal thermometers to observe how heat flows by conduction, convection, radiation, and evaporation.
Sodium Acetate Hand Warmers
Source Institutions
In this activity, sodium acetate hand warmers are used to introduce learners to supersaturated solutions, crystallization, and exothermic reactions.
How Greenhouse Gases Absorb Heat
Source Institutions
Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.
Taking Its Temperature
Source Institutions
In this activity (pages 5-7), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
Hot Stuff!
Source Institutions
In this activity, learners discover that sand is the major ingredient in glass.
