This is a simple, interdisciplinary worksheet for science or math students. It walks students through the steps of figuring out how many times bigger the sun is compared to the earth (by diameter, and then by volume). The first page of the document is the worksheet; the second page is the answer key. Primarily written for an Earth Science or Astronomy class, but can be useful in a Math class, too. The math involves substituting numbers into an equation and simplifying (cubing, multiplication,

This activity guides students in studying how spherical the earth is. I would use this after students have already learned the term "oblate sphereoid," so that you can then use this to discuss with them How oblate is it? Students will do some simple calculations (basic ratios) to discover the relief that the highest and lowest elevations on Earth would have if the earth were shrunk down to the size of a (32cm diameter) classroom globe.

When asked which math topic is their least favorite, many students would say Proofs. This is understandable, especially when students don't have good examples to study. This packet contains nine proofs in various forms: fill-in-the-blank (for if you are just starting proofs with your class), unstructured (for classes who have been practicing proofs for a bit and don't need the help), and the answer keys (suitable to go with either previous version). I envision this packet as a transition betw

This worksheet gives a graph (showing the temperatures of soil and water as they heat & cool) and asks students to calculate the rates of change on various intervals. The handout is printable in black/white/grey, and the answer key is attached (answers are filled-in in color). This worksheet is suitable for an Earth Science class as an application of specific heats and rates of heating/cooling, or a Math class as practice reading graphs and calculating slopes.
