The longer lines on the metric ruler are called… centimeters
The shorter lines on the metric ruler are called… millimeters
One centimeter is divided into how many millimeters? 10 millimeters (mm)
Figure 2: Calculating: Measure the turtle in figure 2 from the rear of its shell to the tip of its nose. Record its length in both centimeters and millimeters. 10.5 cm 105 mm
Mass The measure of the amount of matter an object contains Matter: The material that all objects and substances are made up of Anything that has mass and takes up space is matter
A smaller object’s mass such as a paper clip would be measured in Smaller objects such as a paper clip would be measure in milligrams.
How does a triple-beam balance work? A triple-beam balance works by comparing the mass of the object you are measuring to a known mass When you use a triple-beam balance, you: 1.Place the object on the pan 2.Shift the riders on the beams until them balance the mass of the object Start with the large rider (increments of 100) Next, the medium sized rider (increments of 10) Lastly, the small rider (increments of 1)
Label the different parts of the triple-beam balance.
Figure 3: Observing - What is the mass of this turtle? 153.7 grams
How would your weight differ if you were to travel to the moon? If you were to travel to the moon your weight would be less. Your weight would be lesser because the force of gravity is less. Weight is a factor of the force of gravity
How can the volume of a solid object such as a shoebox be measured? To measure a solid objects that are regular shaped, a formula for volume can be applied To measure a rectangular object such as a shoebox, multiply the object’s length, width, and height
Suppose a cereal box is 10 centimeters long, 4 centimeters wide, and 20 centimeters high. What would be the volume of the box? Volume = Length x Width x Height Volume = 10 cm x 4 cm x 20 cm Volume = 800 cm³
