Hands-On Challenge: Gravity, Mass, and Force
- Marble Rush® Tip & Swirl Set™
- 5 marbles
- Coins (variety of sizes)
Let's see how much mass, or how many marbles, it takes to tip the Green Flip and Tilt Barrel. First, complete the Level 1 Build as illustrated. Then, start by dropping one marble down the barrel. Keep adding one marble at a time until the barrel tips over. Make note of how many marbles it takes for the barrel to tip over.
Take a coin and tape it flat to the backside of the barrel as shown. Use your finger to tip the barrel and release it. Do the same to the other barrel without the coin taped to it. What difference do you notice between the two barrels when they are tipped? Based on the difference you observe, predict whether you will need more, fewer, or the same number of marbles to make the barrel tip.
Test your theory about the number of marbles needed and drop one at a time into the barrel until it tips. Try it out with coins of different sizes, or multiples of the same coin. Think about how the mass of the coin changes how many marbles are needed to tip the barrel.
Exploring Mass and Gravity
Let’s explore how objects with different masses interact with the Green Flip and Tip Barrels.
Additional Materials Needed:
- Marble-sized objects like glass marbles, pom poms, beads, small pebbles, small erasers, buttons, plastic building-blocks, individually wrapped candy (e.g. mints, hard candy), and coins
- Aluminum foil, plastic wrap, paper, modeling clay and/or other materials that can make balls of similar size to a marble
- Download and print a copy of the Exploration Charts 1 & 2
- Something to write with
Exploration 1:Remove the Yellow Ramp (T-14) and the tower of blocks from the Level 1 build as shown. Gather your marble-sized objects. Place one of the objects into wide-mouth end of the barrel as shown.
Using Exploration Chart 1, write down the name of the object and record if the object was able to tip over the barrel.
- Why do you think some objects are able to tip the barrel while others are not?
Exploration 2:In Exploration 1, we tested different objects to see if their mass could tip over the barrel. Now, take multiples of each object that were not able to tip over the barrel. For example, if you used a bead in Exploration 1, gather a few more for this round. Place the object into the wide-mouth end of the barrel. Keep adding more until the barrel tips or there is no more space left.
Using Exploration Chart 2, write down the name of the object, how many of each object was used and if it was able to tip over the barrel. Based on the information from your chart:
- Which objects are heavier than others?
- Which object is the heaviest?
