Can you measure it?
Can you accurately measure your own shoe in centimeters
Varies, 20-35cm
What is the main unit of length in the metric system. This unit is equal to 3.3 feet.
The meter
What is found by dividing mass/volume?
Density
If a boat is loaded with 10g of weight and displaces a maximum of 5g worth of water, will it sink?
Yes, it will sink
Accurately find the mass of an object in grams.
Varies
How many centimeters are in a meter?
100 centimeters
C. because opposites attract, especially at a closer distance.
If an iron block has a mass of 2g and volume of 1 cm3, what is its density?
2 g/cm3
If a boat has displaces 100ml of water, will it sink with 50g of weight?
No, because 100ml of water=100g, more than 50g
What is the volume of the medium sized blue sheet in cubic centimeters?
100 cm3
How many meters are in a kilometer?
1,000 meters

Page 3, Question 1
A) The graph show the ball speeding up and then rolling continuously.
You are sold a gold block, but do not trust if it's pure gold.
How can check its with only a scale, a measuring cup and some water?
Use the water and measuring cup to measure it volume.
Measure its mass with the scale.
Find its density.
Check if it matches the density of gold.
Sink. It has more weight than the water it displaces.
Can you find the mass of water without the mass of its container?
Option 1: Tare the scale so it reads zero with the container, then add water to measure it.
Option 2: Measure the volume in milliliters (ml). This number will be the same in grams (g).

D) There is no force acting on the object, so the velocity does not change.
A. The density of container 2 is one-half the density of container 1.
