Question:
How can you find the volume and density of two regular solids, two irregular solids, and two liquids?
Discussion:
Density is a physical characteristic, and is a measure of mass per unit of volume of a material or substance. Density is mass divided by volume. It is a measurement of the amount of matter in a given volume of something. Density is a very important property which can be used to identify a substance.
Materials:
- 2 Regular Solids (Cannot be the same)
- 2 Irregular Solids (Cannot be the same)
- 2 Liquids (Cannot be the same)
- 1 Triple Balance Scale
- 25 mL Graduated Cylinder
- Distilled Water
- Safety Goggles
- Apron
- Close Toed Shoes
- Ruler (foot long)
Procedure:
- Measure the length of the object in centimeters.
- Measure the width of the object in centimeters.
- Measure the height of the object in centimeters.
- Multiply length by width, and then multiply the product by the height.
- Fill the beaker up to a testable amount in which the object may be placed in without the distilled water overflowing.
- Record amount of water.
- Place the object in the water and record the new measurement.
- Subtract the first measurement from the second and record answer.
- Pour the liquid into the graduated cylinder.
- Record the measurement from the lowest point of the meniscus.
- Set the weights until the triple beam balance is balanced.
- Find the mass of the object in grams.
- Document the conclusion.
- Set the weights until the triple beam balance is balanced.
- Find the measurement in grams.
- Document the answer.
- Document the mass of the container as was done with the regular and irregular solids and record the answer.
- Pour liquid into container.
- Find the mass and document answer.
