No matter where you place this ball, it stays suspended in this liquid. The density of this liquid is 4 g/mL.
The ball has a density approximately equal to the density of the liquid because it stays suspended in the middle/wherever you place it. So approximately equal to 4 g/mL.

Sora finds a rock and wants to identify it as Pumice or Lava rock. The two rocks look identical and have similar physical properties so she decides to use their densities to determine the identity. Pumice has a density of 1 g/cm3 whereas Lava Rock has a density of 2 g/cm3. The mystery rock has a mass of 400 grams and since it is an irregular solid, Sora uses the water displacement method to find the volume. Using the photo below, calculate the density and identify whether the rock is Pumice or Lava rock.
2 g/cm3
Lava rock

Identify whether each of the statements below are true or false. If they are false, correct them to make them true.
1. Cutting a piece of bread in half means the density of the half-piece of bread will be half what it was when it was a full piece of bread.
2. Cutting a piece of bread in fourths means the density of the fourth-piece of bread will be one-fourth what it was when it was a full piece of bread.
3. Recombining the small pieces (the fourths and halves) of bread back into one large piece of bread will cause the density of the one larger piece to be higher than the densities of the smaller pieces.
All of these are false. Changing the amount of a substance does not change the density of the substance. If the density of the bread was 2, then the density of the 1/2 piece is 2. Then density of the 1/4 piece is 2. The density of the recombined piece is 2.

Compare the densities of the purple ball vs the green ball if the liquid they are in has a density of 3 g/mL.
The purple ball is less dense than the green ball because it is floating slightly higher.

Milo finds a cube in his bin of toys and decides to find its density. When he measures one of its sides it comes out to 4 cm and when he places the cube on a scale it measures in at 64 g. Calculate the density of the cube.

Explain, in detail, the relationship between temperature and density. You may use the examples discussed in class such as lava lamps, hot air balloons, or the temperature differences between the basement and attic of your house.
Hot substances are less dense and rise while cold substances are more dense and sink. So cold, dense air sinks to the basement and hot, less dense air rises to the attic.
