Light and Energy Investigations

The video tutorial guides students through a lab investigation to explore how light affects different materials. It includes experiments with liquid crystal paper, solar panel toys, and temperature changes. Students are encouraged to make observations, draw inferences, and understand the concept that light carries energy. The tutorial also introduces an anticipation guide for further exploration and suggests at-home experiments.

What is the initial color of the liquid crystal paper before the flashlight is shone on it?

• Purple

• Yellow

• Greenish-blue

• Red

What change is observed in the liquid crystal paper after exposure to the flashlight?

• It remains the same

• It changes to navy blue

• It becomes transparent

• It turns red

What happens to the toys with solar panels when exposed to the flashlight?

• They make a sound

• They start to move

• They change color

• They remain still

What is the starting temperature of the thermometer placed under the light?

• 80 degrees Fahrenheit

• 85 degrees Fahrenheit

• 90 degrees Fahrenheit

• 95 degrees Fahrenheit

What is the ending temperature of the thermometer that was not under the light?

• 88 degrees Fahrenheit

• 96 degrees Fahrenheit

• 90 degrees Fahrenheit

• 84 degrees Fahrenheit

What key concept about light and energy should be noted in the science notebook?

• Light does not affect materials

• Light is a form of sound

• Light carries energy that causes materials to change

• Light is a solid object

How is light described in terms of its physical nature?

• A type of particle

• A type of liquid

• A type of gas

• A type of wave

What is the purpose of the anticipation guide mentioned in the video?

• To learn about sound waves

• To study the effects of gravity

• To explore the relationship between light and cancer

• To test knowledge on math

What should students do for the at-home investigation?

• Find objects and expose them to a light source

• Use a microscope to study cells

• Build a model of the solar system

• Conduct a chemical reaction

What should students record in their science notebook during the at-home investigation?

• The type of light source used

• The time of day

• The color of the objects

• Any changes observed in the objects
