Density Observation Lab

1- Density Beads

Observe the density beads. What do you notice?

Under the explanations portion, tell me, in terms of density, why this is happening. How many different substances must be in the bottle?

3- Oil, Corn Syrup and Water

The oil is colored yellow, the water is colored blue, and the corn syrup is colored red in the picture.

Write down your observations. What do you notice?

In the explanations section, tell me, in terms of density, why this is happening.

4- Density Cubes

Density= Mass ÷ Volume. Volume of a solid rectangular prism is measured by finding the length x width x height of the object.

Under observations, write the density of each of the objects.

Under explanations, give me the order of the objects from most dense to least dense.

Cube one has a mass of 100 gCube two has a mass of 250 gCube three has a mass of 10 gCube four has a mass of 150 g

5- Density Cylinders

Density = Mass ÷ VolumeVolume of a cylinder = πr2h (r= Radius, h=height, π = 3.14)

Under observations, write the density of each of the objects.

Under explanations, give me the order of the objects from most dense to least dense.

7- Eggs in WaterThe egg on the left is in tap water. The egg on the right is in a saltwater solution.

8- Pebbles and Sand in Water

This bottle was filled with water, loam (rich, organic soil), sand and gravel. It was then shaken and left to settle.

Observe what is happening. What do you notice?

In the explanations section, tell me, in terms of density, why this is happening.
