Intro to Physics: Day 2

List 5 safety violations in this picture1. Goggles not worn on

eyes2. Girl is wearing open-

toed shoes3. Backpack and books

not put away4. Girl did not pull hair

back thus caught on fire

5. Boy drinking toxic substance

6. Boy did not clean up chemical spill

7. Chemical not to be disposed of in waste basket

Page 5: Bell Ringers

List 5 safe practices shown in this picture

Intro to Physics: Day 3

1. Goggles are on and over eyes

2. Wearing closed toed shoes

3. Handling hot glassware with oven mitts

4. Safety apron is on and tied in back

5. There are no spills on the lab table

6. Lab area is clear of backpacks

What is the scientific method?

What are the parts of the scientific method?

Organized set of investigation procedures used universally to solve problems.

The difference between solving problems in science and real life situations is that we write the steps down.

Intro to Physics: Day 4

Observe the problem

Collect Background Information

ExperimentConclusionRepeat Old Chickens Have Eggs Crack

RegularlyRemember?

Form a Hypothesis

Using your book write down the definition of density. What are the units for density?Why does ice float?

What is the formula for density?

Ice is less dense than liquid water

Density ReviewA liquid has a mass of

7.2 g and occupies a volume of 2.4 ml. What is the density?

GUESS

List the liquids from highest density to lowest density

Determine which has higher density

What is the metric system?

Intro to Physics: Day 8

What is the standard unit of measurement?• Length =

• Volume =

• Mass =

• Time =

meters (m)

liters (L)

grams (g)

A decimal system of units based on length, mass, and time.

seconds (s)
