March, where are you?

Wow! Another snow day! I am looking forward to March and hopefully no more snow?? I hope you are enjoying the extended weekend.

We will review on Monday and your test will be on Tuesday.

Also, remember to look for an article for a class activity next week. The article can be about anything; does not need to be related to science in anyway.

See you Monday!

How much power do you do?

Yes, I made you do some exercise today! The purpose of making you run up the back stairs was to see how much power you used. Check out this link to compare your power output to some common household items. Scroll down. The list is on the right hand side. http://michaelbluejay.com/electricity/howmuch.html

Continue reviewing for your test. As of right now, test is still Friday. IF it nows and there is no school Thursday, THEN the test will be moved to Tuesday. Stay posted!

In class we finished up Lesson 9: Power and Batteries. For homework tonight use your data to complete 2 graphs. See procedures #8 and #14 on page 86. Also be sure to complete A-G on page 86.

Test Friday on lessons 5-9. Start reviewing:

• Forces (friction, gravity, mass, weight)
• Circuits (open, closed, series, parallel)
• Calculating work and power
