Light Waves & EM Spectrum & CRCT practice

Mon. -Wed. We are working on lab stations each day to learn about light waves. All work must be completed in the classroom and is due by the end of class on Wed. Come to school at 8:30am to finish any stations you have n0t finished.

Thurs. & Fri.-We are going to the computer lab to learn about The Electromagnetic Spectrum and EM Waves. Students will complete a webquest and must do it at school. Students can go the the media center as early as 8:00am to work on it if they waste their time in the computer lab. This webquest is due by the end of the day on Friday.

If you will be absent Friday, you can work on the webquest over the break or print it here and finish it by Thurs. at the end of class.  Download EMwavesWebquest
