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.
What Smart Metal!
Source Institutions
In this activity (pages 3-4), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
Rubber Blubber Gloves
Source Institutions
In this experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't.
How Many Pennies?
Source Institutions
In this activity (pages 13-14), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
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.
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.
Air Pressure
Source Institutions
In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.
