Activity One : We will watch the following videos together, or you may watch them individually with headphones. Remember that these videos and questions are available when it is time to review for a quiz or test. Answer the questions for each video topic in your notebook. Use the videos AND any other reliable resource, including your textbook.

A. Laboratory Tools : There are a few lab tools that you should get to know. Others will be learned as we use them in lab. Draw a picture of each and explain what its use is.

1. Graduated cylinder

2. Beaker

3. Test tube

4. Flask

5. Beaker tongs

6. Mass Boat ( Weighing Boat)

7. Test tube clamp

B. Scientific Method : This is a video which will help you to understand scientific method.

1. Question : What is scientific method?

2. Why is the scientific method used?

3. Explain "Claim, Evidence, and Reasoning."

4. Define Hypothesis.

C. LAB Safety: .1 List three safety rules for working in a laboratory. Explain why these safety rules are needed.

D. Metric System :

1.. Why are standard units needed for measurements?

2. What are the metric units , U.S units, and what tool is used to measure the following measurements( On Table A):

3. Find out what the metric prefixes mean in words, decimal and fraction, also give the abbreviation used ( on Table B):

example : milli = one thousandth , 0.001 , 1/1000 , m

Table A:

Table B : Metric Prefixes

A great video , " Powers of Ten" which shows levels of reality from atomic to galactic.
