Two objects are uncovered in an Egyptian tomb. One of the objects is a sphere and has a mass of 360 grams and a measured volume of 36 cm 3 . The other object is cylindrical with a mass of 50 grams and a measured volume of 5 cm 3 . A scientist just made a claim that both objects are made of the same material. Do you agree with her claim? Select the best explanation.
a)
The two objects have the same density so they must be the same substance.
b)
The two objects are different materials because they have very different masses. One object has a mass of 360 grams while the other object only has a mass of 50 grams.
c)
The two objects may not be the same material.
d)
Although the objects have the same density, the scientist needs to test for other properties. Substances can have common properties but no two substances have all of the same properties.

Jin and Maddie’s class is studying metals. The teacher gives their team 4 metal cubes. Two are 1.5 cm cubes, and two are 1.2cm cubes. They need to determine whether any of the cubes are made of the same element. Which investigation would enable them to determine whether any of the blocks are made up of the same elements?
a)
Jin and Maddie should test hardness on one cube, density on a different cube, solubility in water of another cube, and then melting point on the last cube and then compare.
b)
They should make a data table to record the color, hardness, mass, volume, and the melting point of the small cubes and the larger cubes.
c)
Jin and Maddie should test each cube to determine its properties. They could investigate color, hardness, density, solubility in different liquids, and perhaps their melting point. Each test would need to be repeated for each cube.
d)
Jin and Maddie should test the density of each cube. To do that they would measure the mass and volume to calculate the density. If their densities are all the same they will be the same substance.
12.
How do we know if something is a property or not?

What is the evidence?
In our experiment, the blocks had different masses, 20 g., 30 g., 44 g., 123 g and 142 g but the time for all five blocks to fall was about the same. It took between 1.5 and 1.8 seconds for them to fall. No, mass does not affect how quickly an object falls. Since the blocks had different masses but took about the same time, I know that mass does not affect how quickly something falls.
