For this activity, our subject of focus was the properties of matter. In class, we have explored several different ideas within this topic, including understanding the different states of matter, learning about volume and density, and what constitutes as a physical versus a chemical change in terms of matter. The activity itself, “Mass and Density Activity Sheet”, focused on determining the density and mass of certain objects and whether or not these had higher or lower mass/density to the other objects. The objects in question were various cylinders of the same size and shape. The only difference between them was the material that they were made of. Using scales, we found the different masses of each cylinder and were able to try and determine density with the given mass.
This activity is a bit of a trick for those who do not pay attention. It does a good job keeping in showing students how different materials can have different masses and densities while still appearing as the same size and shape. However, some of the questions, or wording in the questions, is a little confusing, and I would probably try to work with it before I actually gave this activity to a class. All in all though, it is a good activity that helps students to really visualize how different matters can have different properties.
