this
experiment introduces Elementary school children the basic principles
involved in the concept of energy. This experiment focuses on two
energy conversions that satisfy the State Standards of grades 3rd
through 8th grades: science as Inquiry: abilities necessary to do scientific inquiry. Physical Science: Tranform
one type of energy into another. The students will investigate 1.
Energy is the ability to do work or to make things go. 2. Energy can be
transformed, or converted from one form into another. You can begin
this experiment by intoducing several types of activities that exist in
our planet. 1. Light: the energy in light makes plants grow and allows
solar cars and solar calculators to work. 2. Chemical this energy is
gasoline makes cars, trucks, buses, and other vehicles go. 3.
Mechanical: this is energy from motion such as water pouring over a
waterfall to turn a water wheel or wind blowing to make a windmill or
sail boat go. 4. Electrical : makes washers, driers, radios, TVs, and
battery-powered toys work. 5. Heat: Can boil water to make steam
engines go or drive generators to make electricity. 6. Sound: Such as
an opera singer's voice or a powerful clap of thunder, have so much
energy that they can break glass or make your body vibrate. Then you
begin your experiment: 1. Cut a spiral from a sheet of aluminum foil.
carefully Poke a small hole in the aluminum foil with a push pin. Put a
piece of thread through the hole and use a small piece of tape to hold
the thread in place. 2. Hnag the spira; by the thread, and hold it
about 5 cm above a lamp. What happens? How might you change the spiral
to make it spin faster? List as many ways as you can think of.
Accoding to Larry D. Kirkpatrick and Gregory E. Francis Physics a World View 6th Edition. the reason the aluminum foil swirl around once exposed to the light is because "heat is transformed into other forms of energy. If the molecules have more than one atom, part of the internal energy is transformed into rotational Kinetic energy of the molecules and part it can go into the vibrational motion on the atoms," therefore making the object move(www.thomsonedu.com). Also, light has the capacity to jiggle the atoms, so it has the capacity to transform heat energy to Kinetic energy by exerting light waves into the air making the spiral aluminum spin.
