was it true or false

inference

conclusion based on evidence

theory

explain

What is an example of quantitative data?

1. NUMBERS-Data that deals with numbers. Measurement 

What is an example of qualitative data?

1. WORDS-Description- Grass is green

1. Where does the independent variable & dependent variable go respectively on a graph?

IV- goes on the bottom

What is an example of an independent variable?

1. Something that we purposely change-

IV: Percentage of fertilizer

DV: The height of the plant

The metric system is based on what multiple(multiply by what base)?

1.  Powers of 10

List some units of the metric system

1.  Distance/Length- Meter

Mass- Grams

Volume- (liquid)- liters

How is length measured in the metric system? What unit?

meter

How is mass measured in the metric system? What unit?

gram

How is volume measured in the metric system? What unit?

liter

How is temperature measured in the metric system? What unit?

Celsius

What tool do you use to measure length?

1. Ruler or meter stick

What tool do you use to measure mass?

scale

What tool do you use to measure temperature?

thermometer

What are some of the rules during a lab that one should follow?

1. Wear PPE- goggles, closed toed shoes, gloves, tie hair back

What is an example of an observation? What is an example of inference from that observation?

1. It is cloudy outside- observation–Inference- It may rain today?

1. What are the steps to the scientific method?

Make observations

Ask questions

Research 

Create hypothesis

Experiment

Collect data

Conclusion

Share data

1. What is the format for a hypothesis?

IF (IV) 

Then the DV

Because 

1. What are the parts of a graph?

Title- DV as a function of IV

IV- labeled with units on the bottom

DV- labeled with units on the side

1. What is the volume of the rock below?

Measure the water in the graduated cylinder. Then add the rock and measure the liquid.

Then subtract the two measurements for the volume of the rock. 

IF it is a square shape you just have to multiply the L x W x H.
