Attention all grade 4 scientists! We will be starting our Science & Technology unit on Light and Sound this coming Monday. It will be an exciting unit that will teach you all about the characteristics and properties of light and sound. Throughout the unit we will explore a variety of concepts that will allow you to become experts in the area of light and sound. By the end of the unit you will come to understand that light and sound are forms of energy, that sound is created by vibrations, and that light is required to see. We will end the unit by completing a research project. Stay tuned for the research project topics.
Here are some quick facts to introduce you to our Light and Sound unit. Enjoy!
Ø Light is energy that travels in waves.
Ø Light speed is the fastest mode of travel.
Ø Light travels in straight lines.
Ø Light is reflected when it bounces off an object and travels in different directions. Mirrors reflect light.
Ø Light is refracted when it travels through an object and is bent.
Ø Light is transmitted when it passes through an object.
Ø Sound is energy produced by vibrations.
Ø Sound travels through solids, liquids, and gases.
Ø Frequency=pitch.
Please visit the Science Spot as an introduction to our Light and Sound unit. Looking forward to tomorrow!
