8R Science Final Review- 2

The diagram below shows water in a graduated cylinder. A student states that the graduated cylinder contains 150 mL of water. This statement is

• a prediction

• a theory

• an observation

• a hypothesis

The diagram below shows 20 grams of two different materials, A and B, on laboratory   balance.
Compared to material A, material B has a different

• density 
• phase
• mass 
• shape

What is the volume of the liquid shown in the graduated cylinder? _________mL                         

• 40 mL
• 41 mL
• 43 mL
• 4.3 mL

The volume of the rock is _____ mL.

• 10 mL
• 100 mL
• 1000 mL

What is the density of SAMPLE 1?

• 89 / 10 = 8.9 g/mL
• 10/89 = 0.1 g/mL
• 89 x 10 = 890 g/mL

A hypothesis is a

• possible answer to a problem.

• factor that is changed during an experiment.

• factor that stays the same during an experiment.

• the use of one or more senses to gather information

Which skill are you using when you use your five senses to gather information?

• observing

• posing questions

• designing experiments

• developing hypothesis
