Over the next two weeks we will look at Newton's Laws of Motion.
What is Newton's First Law?
What does it mean?
On p. 46 of your text there is an activity to design a lab that find the mass of an object without weighing or holding the object. You had to use your knowledge of Newton's Laws and how mass affects inertia. How did your group do in creating a way of finding mass without touching the object?
We also want to be finding interesting experiments in physics. Why are they important and how do they tie in with what we are covering? To help get the ball rolling we will look at some great discoveries and experiments throughout history in the Science Channel's presentation of 100 Greatest Discoveries: Physics.
This weeks contract has you designing a lab, demonstration, inquiry that teaches us about Newton's First Law. The best presentations will be done by both classroom groups on lab days(Wednesdays).

Eighth Grade Week 22
In this section we look at how atoms combine to form chemicals and the effects of those bonds?
What are the properties of compounds that have covalent bonds? ionic bonds? metallic bonds?
How does the type of bond influence the structure of the compound?

Seventh Grade Week 21
We move from position and motion to speed and acceleration.
What is speed?
What is acceleration?
How are they measured?

This section explores why elements bond to form compounds?
How do elements bond to form compounds? Why?
Explain the Hydrogen peroxide and Manganese dioxide reaction?

Seventh Grade Week 20
Like the Eighth grade, we also change gears and turn to Physical Science. We focus on Physics and begin with Motion and Forces
What is position?
What is motion?
How are both measured?

Eighth Grade Week 20
This week we take a close look at the periodic table. Mendeleev and others since have arranged elements into a Periodic Table of the Elements. The power of Mendeleev's table is that he could make predictions about unknown elements.
How are elements arranged on the periodic table?
Why do elements in groups share similar properties?

This weeks contract has you select a unique element from the periodic table and design a poster for its square on the Periodic Table. The best posters will be set into our ceiling Periodic Table of the Elements for all time, or until it is replaced...so come up with your best design.

Eighth Grade Week 19
We leave the natural resources concepts of the Changing Earth and Earth's Waters units, and focus our attention on the integrated concept of change throughout the units. In the Chemical Interactions unit we will look at how things change on the smallest of levels.
What is the structure of an atom?
How does this structure lead to some elements forming ions?
This weeks contract has you select a unique element from the periodic table and design a model of its structure. I will have one question when you present. How does the structure of the element affect its function? Good luck, and pick a winner fast before someone else does.
