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,

Students graph distances to various galaxies vs their speeds, and infer a direct relationship between the two. Skills Practiced: graphing, reviewing the main graph types, applying math concepts to real life

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.

This laboratory activity about Earthquake Depths is a great math-science crossover! It gives students practice with latitude & longitude and helps them process the fact that earthquakes don't just happen at Earth's surface but at varying depths. Specific skills practiced are plotting latitude & longitude coordinates on a map, plotting longitude vs depth on a graph, and visualizing the same data from multiple perspectives. This is real earthquake data from actual earthquakes in South America.

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

In this laboratory activity, students will use a loop of string and two tacks to draw one circle and four different ellipses. They will then measure the focal distance and major axis of each of these, and use this data to calculate the eccentricity of each ellipse (and the circle). The analysis questions lead students to discover the overall patterns and apply the knowledge learned in this activity to planetary orbits. Note: Parts of the lab refer to the ESRT. This is New York State's Earth

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.
