- The group in an experiment which does NOT receive the independent variable and is used for comparison purposes is called the ____________ _____________.

- The group that is being tested and therefore DOES receive the independent variable is called the ___________ ___________.

- Variables that the experimenter tries to keep the same throughout the experiment for both the control group and the experimental group are called ________________.

- The variable which is being tested, and therefore the experimenter changes it on purpose, is the ____________ __________.

- The variable that is being measured, or was affected by a change in the experiment, is the ___________ ___________.

- What is the base unit of length?

- What is mass, what instrument do we use to measure it, and what is the base unit of mass?

- What is volume, what is the base unit of volume, and what instrument do we use to measure volume?

- How do we use the diagram on the board to convert from one unit to another?

- What is the freezing point of water in degrees Celsius?

Mass is the amount of “stuff” something has. We use a balance or scale to measure it in grams.

200 pts.

Volume is how much space something takes up. It is measured in liters and we use a graduated cylinder.

300 pts.

Place finger on starting unit, count how many times your finger moves and in what direction. That is how the decimal moves.

- Name three safety rules for the classroom/ lab.

- Make one qualitative observation, one quantitative observation, and one inference about this picture:

- In our Matchbox Car Activity, what were the independent and dependent variables?

- Describe two ways to find volume.

- Convert the following:
2500cm = _______ km

No horseplayNo Eating/chewing gumWear GogglesWash your hands

100 pts.

Qualitative- pancakes on rabbit’s head.Quantitative- rabbit has two ears.Inference- the pancakes fell on the rabbit’s head.

200 pts.

Independent Variable- height of ramp.Dependent Variable- distance car traveled.

300 pts.

Use a graduated cylinder or multiply length x width x height

400 pts.

2500 cm = .025km

500 pts.

- A thought or assumption based on observations is called a(n) __________.

- Explain the difference between qualitative and quantitative observations.

- What is the basic unit of temperature in the metric system?

- List the four types of graphs we’ve talked about in this class.

- Draw an experiment outline chart and explain how to fill it in.
