When you use knowledge and reason to make sense of your observations, what is it called?

Inference

How do physical properties: malleable and ductile, differ?

Malleable is if something can be hammered into a sheet and ductile means can it be stretched into a thin wire

Define viscosity.

A fluids resistance to flow

A scientist is interested in learning about how salt added to water affects the boiling point of water. Develop a hypothesis for an experiment the scientist could perform to learn more. Identify the independent and dependent variables in your proposed experiment.

When graphing the relationship between variables, which variable should go on the x axis, and which one should go on the y axis?

The independent variable goes on the x axis and the dependant

variable goes on the y axis

How does the shape of a snowball affect the time it takes to melt? State the independent,

dependent and controlled variables.

Independent: shape of snowball. Dependent: time to melt.

Controlled: same person making the snowballs

Which brand of paper towel absorbs the most water? State the independent, dependent and

controlled variables

Independent: different brands of paper towel. Dependent: absorption of water. Controlled: size of paper towel used.

Describe the difference between precision and accuracy

Being accurate means that 1 measurement was exactly right but being precise means you have repeated the experiment and found consistent results

Calculate the volume of a rectangular block that is 1000 mm long, 0.8 dam wide and 0.13 m high. Answer in cm3.

1000 mm = 100 cm0.8 dam = 8 cm0.13 m = 13 cm

Volume = L x W x H= 100 cm x 8 cm x 13 cm

= 10400 cm3

Rearrange the following formula and solve for x.

X = 15
