Unit 1 Science Assessment

The thing in the experiment that you purposely change. (What I change)

• Independent variable
• Constant variable
• Control variable
• Dependent variable

The answer (data) you are looking for. It is what you are observing during the experiment.

• independent variable

• hypothetical data
• theory data
• dependent variable

The things you keep the same in the experiment. There is usually more than one.

• Dependent variables
• Hypothesis
• Independent variables
• Controlled variables

Scenario: Does the angle of the ramp change the distance a toy car will travel? What is the independent variable?

• The angle of the ramp.
• The color of the ramp.
• The surface material of the ramp.
• The weight of the toy car.

Scenario: Does the angle of the ramp change the distance a toy car will travel? What is the dependent variable?

• The angle of the ramp.
• The color of the ramp.
• distance the car travels

• The weight of the toy car.

Scenario: Does the angle of the ramp change the distance a toy car will travel? What are the control variables?

• The angle of the ramp and distance traveled

• ramp and toy car

• distance the car travels

• The weight of the toy car.

Who observed the first cell in the 1660s

• Louis Pasteur
• Gregor Mendel
• Anton van Leeuwenhoek
• Robert Hooke

Can cells be seen with the naked eye?

• No, most cells cannot be seen with the naked eye.
• Yes, all cells can be seen with the naked eye.

What are the components of the Cell Theory?

• ALL organisms are made up of cells (one or more)

• The cell is the basic building block of life (in structure and function)

• Cells can be observed by the naked eye and do not need to divide to form new cells.

• Every cell comes from another existing cell (cells divide to form new cells.)

What are the parts of cells that perform different functions to keep the cell running called?

• Organelles
• Organ systems
• Tissues
• Cells
