Float Add 5 g additions of salt to the water, dissolve, check to see if ball floats. Continue with this method of successive additions until ball floats. Re-weigh remaining salt and subtract this amount from 50.0 g to determine the amount of salt needed.
How do you make a golf ball float in water?
Let students hypothesize how many tablespoons of salt they think they need to add to the water in order to make the golf ball float. 8. Students should add a tablespoon of salt to one cup of water in the jar. Then they can put the lid on the jar and shake until the salt is dissolved into the water.
Does a golf ball float or sink in saltwater?
Therefore, the ball floats on top of the saltwater. The colored fresh water is not as dense as the golf ball, so the ball sinks in the colored water.
Why does a golf ball float in colored water?
Source Institutions. In this activity (on page 2 of the PDF), the learner places a golf ball between salt water and colored fresh water. The golf ball is not as dense as the saltwater. Therefore, the ball floats on top of the saltwater. The colored fresh water is not as dense as the golf ball, so the ball sinks in the colored water.
How do you test if a golf ball floats or sinks?
Students should add the golf ball to the jar to see if it floats or sinks. If the golf ball doesn’t float, students should continue adding and dissolving tablespoons of salt to the jar, one at the time, until it does. 9. Have students discuss why the golf ball floated.
How do you make a golf ball float in saltwater?
Fill the tall container half full of water and pour it into the mixing container.Place the Golf ball into the mixing container, you will see it sinks keep adding salt and stir until the Golf ball floats.Take the Golf ball out and put it into the tall container, pour the salt solution into the tall container.More items...
Can a golf ball float in salt water?
Unlike freshwater, saltwater can be more dense than a golf ball unit, meaning that the ball will in fact be buoyant. It's rare that a golf course water hazard will contain saltwater rather than freshwater, but if you happen to be hitting golf balls into the sea, then they may indeed float!
How does density affect whether or not the golf ball will sink or float?
Real golf balls don't float because they are denser than the water. The higher the density of the object, the less likely it will float.
How did you determine the density of your golf ball?
Students can also bring in materials to test whether or not they will sink or float. Additionally, students can calculate the density of the golf ball using the density = mass/volume algorithm. 12.
Do balls float in water?
Although the bubble wrap makes the ball weigh a little more, it also displaces extra water making the ball more buoyant. The pockets of air in the bubble wrap mean that the ball and bubble wrap together are less dense than the water, which means the ball floats!
Do biodegradable golf balls float?
Environmentally Friendly Characteristics: Wood in its natural form is 100% biodegradable. The Eco Golf Ball is safe to hit into fresh or salt water. The Eco Golf Ball will float, and can be picked up and used over and over.
What factors affect floating?
Float or Sink? If an object has a density less than that of water, it will float. If an object has a density more than that of water, it will sink.
How do you determine if an object will float?
Key ConceptsThe density of an object determines whether it will float or sink in another substance.An object will float if it is less dense than the liquid it is placed in.An object will sink if it is more dense than the liquid it is placed in.
Does a higher density float or sink?
If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float. Density is a characteristic property of a substance and doesn't depend on the amount of substance.
What is the density for a golf ball?
approximately 0.65 ounces per cubic inchUsing the numbers from the rulebook, the nominal density of a golf ball is calculated to be approximately 0.65 ounces per cubic inch.
How do you find the density of a ball in water?
The formula for density is the mass of an object divided by its volume. In equation form, that's d = m/v , where d is the density, m is the mass and v is the volume of the object.
How do you do density?
The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
How to make a golf ball float?
Steps: 1. Put students in groups of 2-3. 2. Ask students to hypothesize whether they think a golf ball will float or sink when placed in a jar of regular tap water. 3. Pass out a jar to each group.
Why does a golf ball sink in water?
Explain that a golf ball sinks in water because the golf ball is denser than water. 7. Have students hypothesize how to increase the density of water. Pass out cups of salt and new jars to each group. Students should fill jar #2 with water as they did for jar #1.
Why does my golf ball flink in the middle of the jar?
It “flinks” (or is it “sloats”?) because the golf ball is denser than the fresh water on top, and is less dense than the salt water on bottom. 11.
