Mass Mass measures the amount of matter an object contains. What is matter? Anything that has mass and takes up space is matter.

Mass The basic unit of mass in the SI system is the kilogram. In our science class we will use the gram as the basic unit.

What are three objects that we could measure in kilograms? 1.person 2.car 3.elephant What are three objects that we could measure in grams? 1.Ingredients for cooking 2.Paper clip 3.scissors

What would you measure smaller items in? milligrams List three objects you could measure using this. 1. a Tissue 2. A grain of rice

Label the different parts of the triple- beam balance. Pan Riders Beams Pointer Tare Knob

How does a triple-beam balance work? When you use a triple-beam balance, you: 1.Make sure that the pointer is at zero and all rider are to the left. 2.If not, use the tare knob on the left side of the balance. 3. Place the object on the pan 4. 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)

Mass vs. Weight Weight is the measurement of gravity placed upon an object. Weight changes based on your location. Mass always stays the same. Mass is measured in grams. Weight is measured in Newtons.

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 different. Your weight would be less because the force of gravity is less.

Would your mass stay constant if you were to travel to the moon? Your mass would stay the same if you were to travel to the moon because mass is the amount of matter that an object contains.
