Chat Preparation Essay

Post your essay answer to the questions below to the Moodle Unit 29 Forum before chat. Log into the Moodle (if you are challenged, use your own Scholars Online userid and password), click on the Natural Science course link, and then on the forum link for this unit. Read any other forum postings.

What role does the ability to correctly predict behavior play in adopting a scientific theory? What happens when a theory doesn't predict behavior accurately -- or when unpredicted behavior is observed? For example, what do you think scientists would do if the Galilean "law of falling bodies" failed, and we suddenly observed rocks falling twice as far as predicted in 10 seconds?

Worksheet

Instead of uploading a worksheet, you'll enter your answers into a Moodle Exercise. It looks like a quiz, but it is different in several ways:

There is no limit to how much time you spend on it.
You can attempt questions you miss several times; you will get immediate feedback.
You can take it over without penalty.
It does have the same due date as your past worksheets (Wednesday night following chat).

Lab Exercise

Lab Instructions: Pendulum Movement.
