For background on why students may benefit from completing the science video worksheets at home the evening before you teach the class, please see: https://youtu.be/_zZuryl1k-c
To save teachers time screening videos, each science video has a 1 minute preview video. You can find those in each subject playlist. The following playlist contains all of the preview videos: https://www.youtube.com/playlist?list=PLTmMqDfxRPOhozl-H1sJmP1R5gXaKKS3E
Viewing options:
- This video is available in standard definition and high definition (1080) resolution. To view high definition: click on the ⚙️ gear icon (settings) then choose 1080 (the gear icon is on the bottom right corner of the video that is playing). You will then see a small 'HD' beside the gear icon with a red box around it. Depending on your browser and internet connection, it may not be possible to play this in high definition (though if you put the video on pause at the very beginning, it may switch to HD if enough video can be streamed before you begin viewing it).
- You may change the play speed by clicking on the ⚙️gear icon (settings) then 'playback speed' then choose a number less than 1 to slow the video down, or a number greater than 1 to speed the video up.

The video introduces students to the
vocabulary and concepts related to electromagnetic and mechanical waves. We
define and give examples of a vacuum and show how all electromagnetic waves can travel
in a vacuum. We define a physical medium, give examples of many mechanical wave groups
and emphasize that all mechanical waves must travel in a physical medium. We define transverse
and longitudinal waves, show these using familiar objects and advanced animations. We recommend
that students vi
ew the video the evening before you present the material in class. That way,
they'll already be familiar with key concepts and vocabulary. Students may pause the video to
read summary slides if they wish. The video's free engagement worksheet is available in many
formats including paper as well as digital ones, such as Google Forms and Canvas. Digital
formats let you quickly identify common errors, and they may automatically enter
individual scores into your grade books.
