Forces,Motion & Simple Machines Review

Ø Equal forces acting on an object in opposite directions. Will not change an objects motion.

Ø When a net force changes an objects motion causes an object to move.

Ø When an objects distance from another objects is changing.

Ø The overall force acting on an object.

Ø A place or object used for comparison to determine if something is in motion.

Ø Both the speed and direction of an object.

Ø Meter

Ø All over the world

Ø Speed- the distance traveled by a moving object per unit of time. Avg.speed- total distance traveled compared to the total time. Constant speed- speed that does not change.

Ø Divided the distance an object traveled by the time it took to travel.

Ø 30km/s

Ø Incline plane, wedge, screw, lever, wheel and axle, pulley.

Ø a flat slanted surface , a ramp.

Ø an inclined plane wrapped around a cylinder, bolts, faucets, jar lids.

Ø an inclined plane that can move, instead of an object moving along an inclined plane. The inclined plane itself moves. Example- zipper.

Ø a simple machine made of two circular objects that rotate on a common axis. Example: screwdriver or doorknob.

Ø a rigid bar that is free to rotate or pivot on a fixed point. A force is exerted on one end and the other end goes in the opposite direction. Example: removing a lid from a paint can.

Ø a grooved wheel with a rope wrapped around it.

A fixed pulley is attached to a structure.
A moveable pulley is attached to something you want to move.

We are in desperate need of tissue and hand sanitizer.  If you could send some with your child, we would really appreciate it. 

Thank you in advance for your help!

Math Retake

I just wanted to let you know that the kids did a lot better on their Math Retake test that I gave today. I am very proud of them. I want my students to be responsible and held accountable for their actions. For the most part, I could tell that students studied and prepared for this test. Way to go!


Progress Reports went home last week. Make sure you've seen your child's grades.

Parent Teacher Conferences & Progress Reports

It's that time of year again. Our spring Parent Teacher Conferences are scheduled for next Wednesday, February 9. Please plan on coming with your child. Students will be dismissed at 10:45. Sign up sheets went home today with directions for you to choose your top three choices in times. Rememeber to turn the sheet in as soon as possible, for the best chances to get the time that you prefer.

Progress Reports went home on Friday, February 3.

Solar System Projects (Newsletters) were due on Monday. Many students still have not turned this major project in.

Science Test Friday, January 28 - Study Guide Below

The Science test is on Friday. Below is the study guide (as a Powerpoint) that we went over in class. Parents, please use the study guide with your child to help them prepare for the test.

As I stressed in class if you study the review and know it, you should do well in the the test. Study the diagram of the sun and know how to label the parts of the sun.

Mr. Rocha's Birthday (Posted by Mrs. Rocha)

This message is from Mrs. Rocha--- (I'm telling you this up front, because Mr. Rocha would never in a million years post this...)

Mr. Rocha's birthday is tomorrow, Tuesday, January 25. Please make sure that you make his day special. He works very hard, and not a day goes by that he doesn't talk about teaching and what he is planning for his students to help them. Just a simple, "Happy Birthday" or card will do the trick. He deserves it.

Progress Reports Go Home This Week

Your grades have now been posted, and those of you that have not turned in your Science Solar System Rough Drafts received a "0" for the assignment until it is turned in. I just want to remind you that this is a major grade, and each day that it is late 5 points will be deducted from the assignment. Many students are now failing science, because they have not turned their rough drafts in yet.

Please make sure that you turn it in. The final written assignment is due this Friday, January 28, but you must first turn in your rough draft in order to receive a score for the assignment and receive feedback. (I have extended the deadline for the final project.) We will be going to the computer lab on Thursday to give students time to merge their final drafts into a newsletter in Publisher. Do not wait until the last minute.
