The total surface area of the United States is 9.6 × 106 km2. Seventy-four percent of this land can support spiders. Given that there are approximately 5.0 × 104 spiders per acre, how many spiders are there in the United States? Recall that 1 acre = 0.004 km2.
A golden-colored cube is handed to you. The person wants you to buy it for $100, saying that is a gold nugget. You pull out your old geology text and look up gold in the mineral table, and read that its density is 19.3 g/cm3. You measure the cube and find that it is 2 cm on each side, and weighs 40 g. What is its density? Is it gold?
Should you buy it? Draw also a figure or free body diagram that support the problem, and the discovery after solving it.

- Jenny wanted to plant sunflowers, but wasn't sure of the best place to plant them on her property - so she decided to investigate! Jenny planted 6 sunflowers where they would get sun all day, 6 where they would get some sun and some shade, and 6 where they would be in total shade all day. Jenny watered all of the sunflowers at the same time of day with the same amount of water. After 3 months Jenny measured how tall the sunflowers in each location were. What is the dependent variable?

It is predicted that humans will have no cholce but to reduce their water footprints in the near future. A water footprint is an estimate of how much water it takes each year to meet the needs of a person, a population, or a country. Currently, the total water footprint of U.S. citizens is 2,487 cubic meters per year per capita (m/yr/ca). This is equivalent to 657,000 gallons/yr/ca, or more than 16,000 bathtubfuls of water per year!
