Gravity

By now, you should understand that mass and weight are directly related. MASS measures the amount of matter in an object and WEIGHT measures the pull of gravity on an object. So, in order to lose weight you must decrease your mass. This also explains why your weight WILL CHANGE in space but your mass STAYS THE SAME.

Mass vs. Weight

Today's investigation led us to examine what effect mass has on an object's weight. Tomorrow we will discuss your findings and look at gravitional force on Earth and other bodies in the solar system. This still leaves us with the question: DOES MASS CHANGE IN SPACE?

We have completed Inquiry 5.1 and 5.2. You are now able to complete ALL  HW assignments for the week.

Reminder: Notebook Quiz on Thursday (Energy and batteries)

Bonus Lab Report

Need some extra points to boost your grade? Then complete a FULL lab report for Inquiry 5.1. Once I grade your report you will decide if you want me to score it as HW, a test or a quiz.

Be sure to follow all the guidelines of a good lab report to earn full credit. Please see me if you have any questions.

Bonus lab report is due on Thursday.

Intro to Forces

In class we used a rubberband to get us thinking about common forces. Our investigation led us to find that the distance that a rubberband is stretched is proportionate to the force needed to stretch. Tomorrow, we will look for a relationship between weight and mass.

Reminders:
  • Notebook Quiz Thursday ~ Energy and Batteries
  • MOS logs due Thursday
  • All missing/make up work is due Thursday
Homework: Doing something a little different this marking period. All HW for this week only was assigned today. All HW is due no later than Friday. There is a section with links at the top of this page.
