This activity will show students how objects change size when heated and cooled. Students will observe a metal tube have expansion and contraction.
Exploratorium
Exploratorium: Science Snacks: Corner Reflector
By creating a kaleidoscope using a set of hinged mirrors students can see themselves as others do! This activity uses mirrors to create multiple images of an object.
Exploratorium
Exploratorium: Science Snacks: Coupled Resonant Pendulums
Understand about a pendulum's natural or resonant frequency in this activity where you create your own pendulums. Students make a pendulum out of PVC pipe, string, and hex nuts.
Exploratorium
Exploratorium: Science Snacks: Coupled Resonant Pendulums 2
Understand the concept of resonance to allow you to cause two pendulums to swing in an identical cycle. Pendulum are constructed from simple materials like string, pencils, paper clips, and pennies.
Exploratorium
Exploratorium: Science Snacks: Cup Speaker
This activity will have students creating their own speaker with a paper cup, coil of wire, and magnet. The speaker operates by changing electric current into sound.
Exploratorium
Exploratorium: Science Snacks: Curie Point
Did you know that a piece of iron can lose its magnetism if heated too high? There is a point called the Curie point when iron is heated to a high enough temperature that its iron atoms are scrambled and can't line up to form a magnetic...
