Daily Objectives:

1. Demonstrate understanding of chemistry concepts  (chemical and physical properties; density)

2.  Describe density as a property of matter

3. Use deductive reasoning to explain how to make a golf ball sink or float in water

S.IP.07.11 /   P.PM.07.24 / S.IP.07.12 /   S.RS.07.15

Today in Class:

1. You and your group should have read and discussed the Procedures that you wrote for your golf ball lab.  You should have completed the Materials (amounts, objects & substances you needed), and you should have written the Hypothesis.  Most of this should have been completed last Friday.

2.  One big concern I have is when you (your group) are not prepared for the lab- in this case, quite a few students did not bring a “substance” for the lab.  You relied on me to bring in what you were asked to bring — and you were supposed to check on this both last Thursday and last Friday.  If you ever cannot bring in something for lab, I will gladly supply you with what you need, if you let me know ahead of time.  However, this is still your responsibility to ask and let me know, or ask your parents.  Lab materials should never have to cost more that $1.00, either (dollar store).

3.  Student groups who came prepared and who had their Procedures/Materials/Hypothesis written completed the Golf Ball Lab, and ran multiple trials.  Great job.  Some groups have elected to come in tomorrow morning because they did not finish their lab or wanted to run another trial.

4.  Most classes saw their results from the Chemistry Quiz #1 today.  Some of you are studying,  and using different study methods, and some of you are not studying, or are not studying when it is assigned.  The Review is Wed. lunch;  Make-Up Quiz is Thursday at the beginning of class.  I announced this in class today.

Homework:

ACTIVELY study ….  chemical and physical properties &  types of matter
