By helping space aliens stranded on Earth, you will learn to identify matter and energy in the surroundings.
After completing this tutorial, you will be able to complete the following:
Matter is what makes up all physical objects. Energy is the potential or ability to move objects (do work) or cause change. Matter is made up of particles called atoms and molecules. Energy can move or change the arrangement of those atoms or molecules. Examples of matter presented in the Activity Object include curtains, a lamp, a stovetop, wires, and a radio. Examples of energy presented in the Activity Object include wind, light, heat, electric sparks, and sound.
A few students may understand that while some scientists draw a distinction between matter and energy, others site Einstein's formula E = mc˛ as evidence that energy and matter are different forms of the same thing. E = mc˛ means that energy equals mass times the speed of light squared. If you multiply the mass of any matter by the speed of light squared, you have energy!
The following key vocabulary terms will be used throughout this Activity Object:
· electricity - energy made available by the movement of electrons through conductors.
· energy - the potential or ability to move objects or cause change in matter. Energy (E) is measured in joules. Forms of energy include kinetic, potential, elastic, electromagnetic, gravitational, light, sound, and thermal.
· heat -a transfer of thermal energy due to a difference in temperature.
· light - electromagnetic radiation, especially in the visible spectrum.
· matter - any material substance that has mass, occupies space, and is made up of atoms.
· sound - series of waves that travel through the air or matter; some frequencies can be detected by the ear and some cannot.
