Mon, June 4	photos; energy roundup; how things fall	Tell an energy story.	Read about energy and measurements.
Tue, June 5	We'll discuss the results of your measurements on falling objects.	Produce your most useful graphs of today's lab, and write up the meaning of it all. Then, ponder other questions to ask or measurements to make.	Read about graphing.
Wed, June 6	Today we'll do an experiment. We want to determine the relationship between speed and kinetic energy.	Determine how long it takes a marble to fall from the top of on e of the lab tables to the floor.
Thur, June 7	First test (a short one), followed by the exciting elevator lab.	Remember, you're calculating what fraction of the gravitational energy got transformed into translational kinetic energy when the marble rolled down the ramp. Then, of course, you're preparing yourself for the test.	Don't forget that there are a few extra questions (easy ones!) in that handout you got the first day.
Fri, June 8	We'll discuss your elevator labs, and then move on to consider springs and force and energy.	Do your lab calculations as though those data were the only data you have. Do you find that the elevator comes to a stop? Or do you calculate that it ought to be still moving?	Here's a little about falling. And a bit about force. And, see the tests page for links to test 1 solutions.
Mon, June 11	afternoon only! You'll tell me what, if anything, you've figured out about spring potential energy. Levers.		Read about work.
Tue, June 12	Be prepared to tell me all about levers, and what they might have to do with work. Ice rink late in the morning - you might want to remember that the ice, and the air above it, will be cold.	Re-analyze your spring energy data, if you can. Produce some good graphs of lever data.	Think about what happens when you use a lever to lift something.
Wed, June 13	We shall continue our discussions from Tuesday afternoon, and get a little deeper into collisions.	Analyze and write down the meanings of your data from the ice rink. Also, answer a couple of questions.	If you didn't go look at the cornstarch demo, here's a video that does not do it justice.
Thur, June 14	Final discussion of your collisions labs. Playground this afternoon!	Answer those questions about momentum conservation and elasticity.	Start answering review questions. Check out the merry-go-round video! And throwing on the merry-go-round! Oh yeah, and jumping off a swing, featuring special guest star Jeremiah.
Fri, June 15	Review session followed by second test.	Remember to do the remaining calculations from the lab.
Mon, June 18	Meet with Max in the morning to receive your tests and to do a lab. Then I'll be seeing you at about 1:30 pm.	Ponder the pendulum: hang anything and watch it swing back and forth. Just a thing at the end of a string will do: What's the importance of the mass of the thing? What's the importance of the length of the string? What if you use a solid object that can swing? Of course, think about energy conservation!	Solutions for the first test are linked to the tests page.
Tue, June 19	We'll finish up our discussion of these basic resonant processes, and then we'll move on to electricity!	Determine the formulas that tell us frequency in terms of length of the pendulum and in terms of the spring constant and the mass.	Solutions for the second test are linked to the tests page.
Wed, June 20	We finish up electricity, and move on to acoustics. In the afternoon we have a little test.
Thur, June 21	Oodles of review.	Get going on those review questions. Come pick up your third test if you like.	Solutions for the third test are linked to the tests page.
Fri, June 22	Final exam available starting at 8 am.	Don't forget to check the tests page for hints, etc.
