The main topic of this year’s science rotation in our homeschool is physics, so I’m preparing a few unit studies that lend themselves well to experimentation and exploration. This light and sound unit study will be first in the line up and is just perfect for 3rd-7th grade students. It’s packed full of meaningful, practical activities that won’t waste anybody’s time.
Great informational books and biographies set the stage, while project-based and research-based activities allow for deeper learning on certain topics of interest.

Light and Sound Books
As with all our unit studies, books pile up in stacks around here. These particular informational and biographical books are great for gaining a broad understanding of light, color, sound, and other physics topics – as well as placing you alongside some of the people integral to modern day uses for light and sound. Don’t feel like to need to have every book at your disposal, but make sure those you do have cover the topics thoroughly.

Most of the time, our vocabulary lessons are fairly casual:
- I call out a vocabulary word and Eli attempts to spell it following all the spelling rules we learned through the Logic of English Essentials curriculum.
- I ask him what he thinks the word means. If he doesn’t know, I’ll use it in a sentence or remind him of a Latin or Greek root we learned during morning time. If he still doesn’t know, he has to look it up in a dictionary (or on the internet) and then use it in his own sentence.
Light and Sound Activities
Our unit studies almost always include project-based or research-based learning activities. These are excellent opportunities to turn the learning over to your children and/or allow them to show what they learned in meaningful ways that encourage research, writing, creating, and public speaking.
I will typically come up with a large list of activity ideas, but only expect my son to choose a handful to complete. From the list below, Eli will choose five projects. I’ll expect him to choose a varied range of activities. In other words, I won’t allow him to choose five of the simplest projects. There will need to be some simpler activities mingled with some that require more research, writing, and planning.
It’s important to let him choose – even if a little guidance is necessary. He takes much more ownership in the final product when he has a say.
You are welcome to assign more or fewer activities for your children. How many you choose will depend on your child’s age and how long you plan to spend on this study. For us, we will only spend 3-4 weeks on this topic. The front end of the study will be loaded with books, videos, and experiments we will complete together from some of the books in our stacks. The last week or two will be turned over to my son for completion of his projects.
You can learn more about how we do project-based learning here if you’d like.
On to the light and sound activities!
– Write the definitions of each vocabulary word on a note card. Create a simple game to play that will help you and a friend remember the definitions. (Language Arts, Science)
– Research about Helen Keller and create a video narration of her life. (Language Arts, History, Science, Technology)
– Research to learn how sound travels. Create a detailed image on poster board to describe the process. (Language Arts, Science, Art)
– Make a flame dance by completing this experiment. Then research sound vibrations to learn how the experiment works. Present the experiment to family members after dinner explaining the science behind the results. (Science, Language Arts)
Cut the bottom off a plastic soda bottle with scissors.
Cut a square from a plastic bag that’s at least 1/2 inches bigger than the base of the bottle. Attach it to the base with a rubber band.
Light a tea light candle, and point the neck of the bottle towards the flame.
Tap the plastic square without moving the bottle. The candle flame will flicker due to the sound waves! (Science)
– Visit a musical instrument store or another place where you can be exposed to a variety of stringed instruments. Carefully, pluck the strings of a few different instruments – if it is allowed – to test the sounds. Ask questions of the store clerks to see if they can help you understand why each instrument and each string sounds different. (Field Trip, Science, Music)
– Write a list of as many stringed instruments as you can think of. Afterwards, look up a complete list. Did you miss any? If there are any on the complete list that you haven’t heard of before, listen to each of them on YouTube. (Music, Language Art, Technology)
– Choose your favorite stringed instrument and write a report. Be sure to include at least one paragraph about how the instrument works and another paragraph about its origin, plus any other interesting things you learn during your research. Include a labeled diagram, too. (Music, Language Arts, Science, History, Social Studies, Art)
– Do sound waves really move things? Find out by completing the following experiment: (Science)
Make a drum by placing a piece of wax paper over a paper cup. Secure the wax paper with a rubber band.
Place two small objects (such as Legos or noodles) on the drum. Trace around them with a marker.
Place a metal pan upside down next to the drum. Bang on the pan with a toy hammer.
Watch what happens to the Legos or noodles. Did they move outside of your traced lines?
– Instruments like organs, trumpets, flutes, and horns make sound because air is vibrating inside them. Choose one of the instruments mentioned (or another that is similar) and find out how it works. Make an illustrated chart explaining in detail how the instrument works. (Music, Science, Art, Language Arts)
– Read a biography of Thomas Alva Edison. Dress up as him and tell a short narrative about his life. (History, Science, Language Arts)
– Thomas Edison made the first sound recordings using his phonograph invention. Watch a YouTube video to see how phonographs work and be ready to explain the process to your family. (Science, Technology, Language Arts)
– Research Alexander Graham Bell and make a timeline of his accomplishments. (History, Language Arts, Science)
– What is echolocation? Write a paragraph explaining it and create a chart of animals that use echolocation to navigate. (Science, Language Arts)
– Research and write a thorough list of the properties of light. (Science, Language Arts)
– Refraction is the bending of light. An interesting effect caused by refraction is mirage. Study this occurrence and tell a fictional story which includes a mirage as part of the setting. (Language Arts, Science)
– Fill a clear glass with water and dip a pencil inside. What do you see? This is a simple demonstration of refraction. Research refraction and be ready to tell about it as you complete this demonstration for your family. (Language Arts, Science)
– What causes rainbows? See if you can write a song or poem to explain what you learn. (Language Arts, Science)
– Make an indoor rainbow with this simple activity. Be ready to explain the results. (Science)
Find a sunny window. Close the blind or curtain, leaving only a small gap to let some direct sunlight in.
Hold a CD, shiny side up, in the beam of sunlight.
Reflect the light onto a piece of white paper.
Change the angle of the CD. You will see a variety of different rainbow patterns.
– Besides the phonograph, Thomas Edison also invented the electric light bulb. How did he discover it, and how did it work? Share the information you learn in a simple skit. (Language Arts, Science, History)
