This document discusses different forms of energy including potential, kinetic, mechanical, solar, light, heat, electrical, electromagnetic, chemical, and thermal energy. It explains key concepts such as the law of conservation of energy, potential and kinetic energy, energy transfer, renewable and non-renewable resources, and electrical circuits. Examples are provided to illustrate different types of energy at work, from cars and toys to batteries and solar panels. The document aims to build students' understanding of energy and where it comes from.

14. (2 ) Refraction - is what happens when light passes from one medium (one type of stuff) into another . When this happens, the light will actually bend. (Actually, it usually splits in two - some of it reflects off the surface, and some of it keeps going through.) The light that goes through bends at the surface. The angle that it bends at depends on what the two mediums are. For example, light will bend a different amount when it goes from air into glass than it does when it goes from air into water

21. Essential Question: What are Insulators and Conductors? Insulator - anything that slows the movement of thermal energy (coolers, Styrofoam cups, fur coat) Conductors - anything that allows thermal energy to move through it easily (most metals). The lunch bag prevents heat in the air from moving Into the bag. This keeps the food in the bag cool. The cookie sheet is a conductor. The oven mitt is an insulator.

22. Essential Question: What is an Electrical Circuit? In order for electricity to work, there needs to be something called a complete circuit . In a complete circuit, energy moves in a circle. It starts out in one place, travels around the circuit, and moves back to the place where it originated. A battery is a good example of how complete circuits work. Batteries are devices that produce electricity by changing stored chemical energy into electrical energy. A chemical reaction inside a battery creates electrons. Once created, the electrons are stored in one end of the battery, called the negative terminal, usually denoted by a “–” sign. When a battery is plugged into a device that needs it, the electrons travel from the negative terminal to the positive terminal, usually denoted by a “+” sign. Batteries can be used to power tiny things like hearing aids or large things like cars.

23. Complete Circuits Circuits need to be complete in order for them to work properly. This means that the wires must go in a full loop around from the power source and back again Circuits that are not complete, WILL NOT WORK!
