Energy - MELTS
Mechanical Energy (potential + Kinetic energies)
Thermal (heat) Energy
The student is expected to explore the uses of energy, including mechanical, light, thermal, electrical, and sound energy.
- There are different types of energy including mechanical, light, thermal, electrical, and sound energy.
- We can use different types of energy including mechanical, light, thermal, electrical, and sound energy.
- Bicycles, stereos, computers, lamps, and toasters are useful objects that demonstrate the use of mechanical, sound, electrical, light, and thermal energy.
- What is energy? What are some different forms of energy?
- How can we use these different energy forms?
- What are some objects you use everyday that require energy?
ELECTRICAL: The student is expected to demonstrate that the flow of electricity in circuits requires a complete path through which an electric current can pass and can produce light, heat, and sound.
- Electricity flows in a closed path to form a circuit and stops when the circuit is broken.
- We can demonstrate that electricity can produce light, heat, and sound when flowing through a circuit.
- Many everyday devices use electricity to produce light, heat, and sound.
- How does electricity travel?
- Electricity can be transformed into which other forms of energy?
- What is necessary to have energy flow through a circuit? What happens if some parts of the circuit are missing?
LIGHT: Student Expectation:
The student is expected to demonstrate that light travels in a straight line until it strikes an object or travels through one medium to another and demonstrate that light can be reflected such as the use of mirrors or other shiny surfaces and refracted such as the appearance of an object when observed through water.
- Light travels in straight lines until reflected or refracted by another object.
- Light is reflected when it bounces off of objects such as mirrors or other shiny surfaces. The image we see in a reflection is a flipped image from the original.
- Light is refracted, or bends, when passing from one medium to another, such as from air into water. A refracted image is a distorted or changed image from the original.
- How does light energy travel?
- How can the path of light be changed?
- What do you observe when the path of light changes?
