Homework Due Thurs 5/2
Your lesson plan must have the following sections:
1. Objective (should start with "Students will be able to...")
2. Description of the science, and why it's important for your students to learn (1 paragraph)
3. Procedures (a table with 3 columns, one for time, one for what the teacher will do, and one for what the students will do)
We are going to add one more section, on safety. Are your students working with anything that could potentially hurt them, e.g. chemicals, sharp objects, electricity, etc.? Put this section right before your procedures.

Sound and Light Retake Instructions (Due Fri March 1)
1. For every answer you got wrong, on a separate sheet of paper, write the number of the problem, your original answer, the correct answer, and 3-5 sentences describing why the answer you chose on the test was incorrect. The sentences are the most important part of the retake; they will determine your retake score. Your paper should look like this:
Problem:5
My Answer: B
Correct Answer: C
I answered B. This is incorrect because...
2. Staple your retake sheet(s) to the front of your sound and light quiz, and turn it in at the beginning of class on Friday.
3. The paper with your corrected answers will be graded as follows:
If you get everything right, including your thoughtful written responses to why your original answer was incorrect, your grade for the quiz will go up by one letter (to a maximum of a B)
If you get at least half of the corrected answers right, your grade for the quiz will go up by one-half letter (to a maximum of a B)
If you get fewer than half of the corrected answers right, your grade for the quiz will remain unchanged.
