LAB 3: MEASURING MASS WITH A BALANCE SCALEWhat is the definition of Mass?

Is Mass the same thing as Weight?

In this lesson you will learn how to find the mass of an object by using a balance scale. Make sure the scale is balanced before placing any objects in it. Place each of the following objects one at a time placing cubes on the opposite side until the scale is balanced. (Note: 1 cube = 1 gram)

LAB 4: MEASURING WEIGHT AND FORCE WITH A SPRING SCALEWhat is the definition of Weight?

Is Weight the same thing as Mass?

In this lesson you will learn how to find the weight of an object by using a spring scale. Make sure the scale is balanced before hanging any objects in it. Place each of the following objects one at a time noticing the weight in Grams (g) and the force measured in Newtons (N). (NOTE: Keep the scale at still to get an accurate measurement)

LAB 5: LEARNING ABOUT NEWTON’S LAW WITH JENGA!

“It's the classic block-stacking, stack-crashing game of JENGA! How will you stack up against the law of gravity? Stack the wooden blocks in a sturdy tower, then take turns pulling out blocks one by one until the whole stack crashes down. Is your hand steady enough to pull out the last block before the tower collapses? If it is, you'll win at JENGA!”

Jenga is a game based Newton's 1st Law of Motion (The Law of Inertia), gravity and friction. Continue removing one block at a time while not upsetting any of the other blocks. Eventually the tower will become unbalanced and topple over.

LAB 6: DOMINO DASH

Page 5 of 7

Domino Dash (1 st Law of Motion) Newton’s First Law of Motion, also called the Law of Inertia, states that objects at rest stay at rest and objects in motion will remain in motion until pushed or pulled by a force. When objects are not moving they are said to be at rest.

Average speed is the rate of motion calculated by dividing the total distance traveled by the total amount of time it takes to travel that distance or S = d / t

Materials

Domino Set Meter Stick Stopwatch Calculator

Procedure:1. Set up all dominoes with equal spacing between them. Set the dominoes in a straight line to cause a chain reaction when the first domino is pushed. 2. Measure the length of the domino row. Record this data in the table. 3. Use the stopwatch to measure the time it takes for the entire row of dominoes to fall after the first domino is tipped until the last is down. Record the data. 4. Calculate the speed at which the dominoes fell. Record the data.5. Set up another row of a different length. Repeat steps 2 – 4. 6. Repeat for a total of five different trials.

LAB 7: MOMENTUM AND MARBLESSupplies needed:• Marble

Page 6 of 7

• Plastic Ball• A ruler with a groove in the middle• A couple of thick hardback books• An index card• Masking tape

First, set up the ruler on top of one book. Fold the index card in half so that it stands up (see picture). The idea is that the marble will roll down the ruler and bump the card. The farther the index card moves, the more momentum the marble has. Use tape to make a line so that you can line up the index card in the same spot each time.

Next, prop the ruler up on two books. Roll the same marble down the ruler. Did the card get pushed farther?

Next, lower the ruler to just one book again. This time, roll the large plastic ball down the ruler instead of the smaller one. How do your results compare to the other two options?
