1. If the six substances listed below were poured into a beaker, where would they settle based on their densities? Draw a density
tower and label the layers in the beaker

2. You are going to drop each of the following three objects into the beaker in your
density tower, draw and label where the objects will settle.
cork: density -0.24 g/cm
marble: density - 2.5 g/cm
plastic bead: density -0.737 g/cm
3. Why do the substances not mix together, but instead form distinct layers? Explain
4. How do the substances layer in a specific order from top to bottom?
5. What determines whether an object sinks or floats?
6. Is density affected by the amount of the substance? For example, what would
happen if you added twice the amount (volume) of the least dense substance to the
density tower? Would it still remain on top or sink lower?
7. An object has a density that is greater than the density of water. How could you
make it float? Explain by giving a real-life example,

On a recent expedition to a remote region of northern canada, scientists uncovered skeletal remains from about 100,000 years ago. surprisingly, all the skeletal remains, which included many species from differing biological families and spanned about two thousand years, showed evidence of experiencing temperatures in excess of 1000 degrees fahrenheit (or 538 degrees celsius). which of the following, if true, best explains the apparent paradox between the cold environment and the evidence of the bones experiencing hot temperatures? (a) chemical changes that naturally occur during the process of decay in only one north canadian species produce the same evidence of the species' skeletons being exposed to hot temperatures as the expedition scientists found. (b) a little over 103,000 years ago, a large fire is known to have occurred in northern canada. (c) strong evidence exists that as early as 70,000 years ago, homo sapiens around the world relied heavily on fire to cook animals. (d) in the same expedition and in roughly the same layer of excavation, scientists found rudimentary wood cutting and hunting tools used by early humans.
