Chocolate (Sea Floor) Lava
Source Institutions
In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.
How does the Atmosphere keep the Earth Warmer?
Source Institutions
In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.
Physical Change
Source Institutions
In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.
Instant Ice
Source Institutions
In this activity, learners observe a quick phase change as water rapidly goes from a liquid state to a solid state.
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.
Meltdown
Source Institutions
In this activity, learners heat ice and water of the same temperature to get a hands-on look at phase changes. This is an easy and inexpensive way to introduce states of matter and thermodynamics.
House Warming
Source Institutions
In this physical sciences activity, learners explore how passive solar design increases energy efficiency.
What's the Angle?
Source Institutions
This activity helps learners understand how the angle of the Sun affects temperatures around the globe.
Give and Take
Source Institutions
In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.
Inverted Bottles
Source Institutions
In this activity, learners investigate convection by using food coloring and water of different temperatures.
Canned Heat
Source Institutions
In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.
Condensation
Source Institutions
In this activity, learners explore the process of condensation.
Make Your Own Deep-Sea Vent
Source Institutions
In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.
Matter of Degree
Source Institutions
In two separate bags, learners mix water with Epsom salts and detergent.
Hot Cans and Cold Cans
Source Institutions
Learners apply their knowledge of heat transfer to design two cans - one that will retain heat and one that will cool down quickly.
Liquid Crystals Interact with Light!
Source Institutions
In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.
Sensory Hi-Lo Hunt
Source Institutions
In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.
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.
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.
Saguaro Nest Cavities
Source Institutions
This activity (on page 3 of the PDF under GPS: Cactus Activity) is a full inquiry investigation into how some desert birds keep their cool.
