Activities
- What is a mass?
- What is a volume?
- How is density related to buoyancy?
- Your teacher took 1L of cold water and 1L of hot water and poured them into a fish tank. What will happen to the water when it is first poured into the tank? What will happen to the water after 5 minutes? After 30 minutes? Why does this happen?
Answer Key/Rubric
- Mass is a measure of how much matter makes up an object.
- Volume is a measure of how much space an object takes up.
- Acceptable responses may include, but are not limited to:
- Density is a measure of the amount of mass in a given area.
- Buoyancy is the ability to float in a substance such as water or air.
- When you have 2 substances, the less dense substance will float on top of the more dense substance.
- When you have 2 substances, the more dense substance will sink below the less dense substance.
- Acceptable responses may include, but are not limited to:
- At first, the cold water will sink to the bottom of the tank.
- At first, the hot water will float on top of the cold water.
- Warm water is less dense than cold water because the molecules move around more quickly.
- After 5 minutes, the water will create three layers: cold on the bottom, hot on the top, and warm in the middle.
- The hot water has the lowest density.
- The waters will begin to mix which creates a layer of warm water in between the cold and hot layer because its density is in between that of the cold and hot waters.
- The cold water has the greatest density.
- After 30 minutes, the water will all be the same temperature. There will not be any distinct temperature layers.
