Flying through forces

Which only means it must be time for a project!

All students are guests in this Science Cafe. Students received their menus today after taking the test. Each student's goal is to "purchase" $25 worth of "dishes". Dishes get purchased by completing the specified task.  Everyone must have an appetizer, a beverage and a dessert. Entree and salads are optional. All tasks, excluding entrees, are individual effort. Only the entree may be a group effort. A group may be up to 4 students from any of my period 1, 2 or 4 classes. Dishes may be turned in as they are completed. All dishes are due no later than March 17.

Check out the top of the page for links to criteria. Also, criteria is posted in the classroom.

Test review

Finally March is here! And hopefully no more snow!

Tomorrow is the test on lessons 5-9. Want to do some review? Click here for the Jeopardy game we played in class.

**Progress reports will be mailed home March 9**

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

What is work?

What we consider work and scientists consider work are 2 different things. In class I reviewed how to calculate work if given force and distance. Please review the problems you worked on in class on Wednesday and complete Student Sheet 8.1b. Do not complete 8.2. That is for Friday's lab.

***The quiz scheduled for Friday has been rescheduled for Monday***

Circuit review

It seems like ages ago we were here (thank you Mother Nature!). We reviewed different types of electrical circuits: series vs. parallel. To practice making your own circuits check out the link below.

HW Tonight!: Write a paragraph describing the hardest work you have ever done. Explain what you did, what forces were being used, and what could you have done to make the work easier on you.

There will be a quiz on Friday on circuits and work. (We have not covered work yet-- that is Wed. and Thurs. lessons).
