Electromagnetic Spectrum, Waves, Sound, & Technology/Properties

Today, you will be completing 4 pre-selected tasks!

• Task 1

• Task 5

• Task 7

• Task 11

I will know I have succeeded when I am able to successfully able to move through 4 of the tasks on the choice board

I will be able to review over the Unit 7 objectives and gain a deeper understanding of the concepts in PS6a,b,c,d abd PS7a,b as well as review over past standards.
