Mr. Blythe

Monday

The CRCT is next week so we are spending a lot of time on review of the 8th grade physical science standards. The students have been great this year and they should be successful on this testing. We started a test on force and motion before the break and they are revisiting that today. We will then move into energy transformations and the Law of Conservation of Energy.

Thursday

Below are the standards we are currently reviewing. You should be comfortable with them and be prepared to be tested on them tomorrow.

• Determine the relationship between velocity and acceleration.
• Demonstrate the effect of balanced and unbalanced forces on an object in terms of gravity, inertia and friction.
• Demonstrate the effect of simple machines ( lever, inclined plane, pulley, wedge, screw, and wheel and axle) on work.
• Recognize that every object exerts gravitational force on every other object and that the force exerted depends on how much mass the objects have and how far apart they are.
• Demonstrate the advantages and disadvantages of series and parallel circuits and how they transfer energy.
• Investigate and explain that electric currents and magnets can exert force on each other.
