Thermometer: Celsius

Spring Scale: grams vs. NewtonsMeasure at the top of the disc.

Each 1 Newton= 100 grams. For example:

An object has a force of 23 g or .23 N

Time limit: not enough

Volume: liquids vs. solids*A milliliter (mL) will fit into a box measuring 1 cm on each side. So, 1 mL = 1 cm3.

*Graduated cylinders are used to measure the volume of liquids.

*The volume of a box can be calculated by multiplying the object's length, width, and height (units=cm3)

*The volume of an irregularly shaped object can be found by measuring the volume of liquid that the object displaces.

Adding the rock changes the water level from 70 mL to 80 mL. So, the rock displaces 10 mL of water. Because 1 mL = 1 cm3, the volume of the rock is 10 cm3.

After the quiz...1. You may work on any questions or extra credit

not finished from the Science Tools Lab. You need to get a copy of the lab sheets when you turn in your quiz.

2. You may read a library book or one from my library.
