Note 1: Students have been shuffled to different periods. When checking grades be sure to check their new second semester section.
Note 2: Students will be building balsa wood gliders. Since students will be allowed to take these home with them, we are asking that students pay $1.00 for supplies. Students who can't or don't want to pay this have two choices: they can do an alternative assignment, or they can talke to me about making other arrangements.
Goals:
1. Friction is a force that opposes motion due to interactions between surfaces.
2. The force due to friction can be measured by measuring the force required to drag an object at constant velocity
3. Be able to describe the effects of different surfaces and weights on the force due to friction.
4. Inertia is the tendency of an object to keep doing what it is already doing.
5. Be able to state and apply Newton's First law.
6. Be able to state Newton's Third Law
7. Be able to apply the third law to every day situations including explaining how a glider gets its lift
Activities
Monday- National ACT Explore Test
Block day - Demonstrations about Friction. Discussion of Newton's first Law.
Homework questions about reading. Sorry there is no electronic copy of this.
Thursday- Magnet Lab
Friday - Notes about Newton's Third Law Homework: List three examples of action and reaction force pairs from the reading on a handout. Sorry the reading is not available on line.
Monday - Presidient's Day
Block Day - Continue poster project in groups - illustrate a situation from a list given in class and draw and label 6 pairs of action and reaction forces on it.
