Science 2: Light and Sound

Click to see optical illusions that will make your brain hurt as well as many other experiments with light and refraction!

Watch this video to learn how incandescent light bulbs are made.

In this fun and easy science experiment for kids, our 'Fantastic Science' teachers demonstrate what happens when light is shone on different everyday materials.

How does light work and how are shadows created? Learn the answers in this video!

You can do three different levels of light experiments so you can learn all about light. Dive in!

Alfredo Moser's invention, a lamp made out of a plastic bottle filled with water and bleach, has been spreading rapidly around the world and it's expected to be in one million homes by early next year.

Expanding on the use of the Moser Light, a group in the Philippines thought of a simple green way to get the lights to work at night.

In this experiment, kids learn about refraction. This is the process in which when light passes from one material to another, it bends or refracts.

Light reflection and vision is awesome! In this lesson, Dr. Jeff, Izzy and Zoe help you learn about it through a fun video lesson for kids

Light is what enables you to see around you. Light is made up of waves. And where do these waves come from?

Watch this fun video to learn new things about light that you didn't know before! Then test your new knowledge

An explanation about what light is and the different types of light that exist.

We learn where it comes from and identify a number of sources of light. We also learn how we can change light through reflection, refraction, or by blocking light all together.

Explore the science of sound with these 4 experiments, then use your knowledge to make your own DIY instrument!

Put the rice on the bowl after you cover it with a plastic sheet and secure it with a rubber band. Play music loudly and bring the speaker near the rice. What do you see?

A lesson on how sound moves from Teacher Aldo.

Dr. Fizzlebop walks fellow scientists through a super simple experiment about the power of sound waves!

Learn how sound is created, how we can amplify and manipulate it, and how different musical instruments create it

How is sound created and how can we hear it? Learn all about how sound works with Jessi and Squeaks on SciShow Kids!

Sound is energy, a special kind of energy. It moves in waves and fills our ears. Find out more about the science of sound.

What does sound mean to someone who is deaf?

Musicians visit the Science Museum of Minnesota where a giant wave tank shows how the different sound waves from their instruments move through the air.

This lesson is designed to help students understand that vibrations are responsible for the sounds we hear. Additionally, they learn that sound vibrations can travel through different mediums.

In this lesson plan, teachers will guide students an exercise to show how white light is made up of light of many colours.

In this lesson, students will learn about shadows and why they can be seen during the day and night.
