Laws of Motion and Systems of Equations
Law 1- Inertia- An object at rest has a tendency to stay at rest, an object in motion has a tendancy to stay in motion unless acted upon by an outside force.
Energy Skate Park (make sure to click on Show Pie Chart and Track Friction)
Law 2- Force = Mass * acceleration
Robot Moving Company (Click on the top tab for RMC, then pay attention to the mass of the object and use the arrows to put the object in the door. The longer you hold the arrow, the more force you apply.)
Law 3: For every action there is an equal and opposite reaction.
Lunar Landing: (Click the arrows to rotate the lander. Use the space bar to apply thrust. Hit once to start. Hit again to stop.)

Snow DAYS
All:
Make sure that you are working on your IXL skills for the week and/or working ahead. Also, if you have not turned in your HERO engine project, I must have it on the day that we return to school.
To think about as you play in the snow:
1. Where does the ice melt first- the sidewalk, the street, or the yard? Why?
2. We didn't have a sled this year, so we have to use household objects. We tried plastic cutting boards, laundry baskets, recycle bins, and cardboard boxes. Which do you think worked best? Why? What else should we have tried?
3. How do potential and kinetic energy relate to sledding?
4. Newton's second law says that Force= mass x acceleration. So does that mean I will always travel faster than Dean on a sled?

Happy New Year
It was nice to see everyone again today and strange to realize that we are halfway through the school year. We will continue our work with force and motion and begin our work with systems of equations as we finish out the last six weeks of the term.
All students received the below document today. The document outlines the IXL skills that are required for the rest of the term.
