### kilo hecto deka deci centi milli

6

## "milli" abbreviation & value

### m ; .001

7

## "centi" abbreviation & value

### c ; .01

8

### h ; 100

11

## "kilo" abbreviation & value

### k ; 1000

12

## Metric Units (without prefixes)

### Gram (g) Liter (L) Meter (m) Newton (N) Degrees Celsius (*C)

13

## Length

### the distance from one point to another

13

## Is mass or weight constant?

### Mass is constant. Weight can change depending on the force of gravity.

14

## Meniscus

### the bottom of the curve; what you read from to determine water level

15

## Formula for the volume of a regular solid

### volume = length x width x height

16

## Appropriate unit for the volume of a regular solid and for the volume of a liquid

###
solid = cm cubed

liquid = mL

17

## Formula for density

### density = mass / volume

18

## Denisty of water

### 1 g/mL

19

1.Problem 2.Research 3.Hypothesis 4.Materials 5.Procedure 6.Data

7.Conclusion 8.Analysis

20

## Variable

### the factors in an experiment that can be changed to affect the outcome of the experiment

21

## 1. Problem

### the question your experiment will answer

22

## 2. Research

### information you need to help write the hypothesis

23

## 3. Hypothesis

### an educated guess for the answer to the problem. you must tell WHAT you think and WHY!

24

## 4. Materials

### things you need for the experiment

25

## 5. Procedure

### the numbered steps to follow when doing the experiment

26

## 6. Data / Observations

### the information you record while doing the experiment

27

## 7. Conclusion

### the results. use the RACE strategy to Restate and Answer the problem and include data to support your answer (Cite evidence)

28

## 8. Analysis

### use the rest of RACE to Explain what worked well, and what didn't. how might you change the experiment? why are the results important?

29

## 5 Golden Rules of Writing a Procedure

###
1. All steps must be numbered (not bulleted)

2. The steps must be in order

3. All steps must be written as complete commands

4. No more than 2 directions per command

5. Steps must provide specific mrasurements and amounts

30

## RACE Strategy in Science (Conclusion)

###
Conclusion:

R - Restate the problem

A - Answer the problem

C - Cite data to support answer
