Vocabulary of light and sound

I learnt light and sound vocabulary. My group completed the slide called draw animate act. We did 4 words each.

The first word we picked was transparent. I stood in front of glass that transparent and made a video of it.

The second word we picked was pitch. We found a photo of pitch to explain what it means.

The third word we did was reflect. We made a animation of light bouncing off a mirror.

The last word we did was echo. We drew what a echo means.
