Wave Interactions Across Materials
Written by Adi Ackerman, Head Teacher
"Wave Interactions Across Materials" is written for 7th Grade (Ages 12-13), and it covers NGSS MS-PS4-2. A 6th grader who is already steady on waves and light can use it too, and an older student can use it as a short review.

7th grade science worksheet: complete reflected, absorbed and transmitted percents and pick materials for a greenhouse roof. Answer key included. Part of our waves, sound and light collection. Aligned to NGSS standards.
How do I use this worksheet?
Start with Wave Speed, Frequency and Wavelength and Measure Waves From Scaled Graphs. Then use the signal and materials sheets to apply the ideas to technology and design.
What students will practice
- Students will fill in reflected, absorbed and transmitted percents so each row adds to 100.
- Students will name a material from the arrows and percents on a wave diagram.
- Students will choose materials for uses such as a greenhouse roof and a dark theater curtain.

FAQ
How do I use this waves, sound and light worksheet?
⌄
Start with Wave Speed, Frequency and Wavelength and Measure Waves From Scaled Graphs. Then use the signal and materials sheets to apply the ideas to technology and design.
What does this worksheet teach?
⌄
Complete reflected, absorbed and transmitted percents and pick materials for a greenhouse roof. The directions on the page read: Read the text. Fill in each blank so its row adds to 100 percent. Then use the arrows and the percent on each diagram to name its material from the table. An answer key is included.
Can I use this waves, sound and light worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th grade waves and light, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
How are amplitude and energy related?
⌄
A wave's energy grows with its amplitude, so a larger amplitude means more energy. Measure Waves From Scaled Graphs has students rank four waves.
What is sampling?
⌄
Sampling is measuring a wave at regular moments and storing each measurement as a number made of 0s and 1s. It is how a digital signal is made.
What are reflection, absorption and transmission?
⌄
Reflected energy bounces back, absorbed energy stays in the material and warms it, and transmitted energy passes through. The three parts add to 100 percent.
