Comments about Including the Science and Engineering Practice
Nowhere does the website overtly say “Hey, you can use this information as evidence to support a claim!” That part will be up to the class. This could be a good opportunity to discuss different types of evidence that can support a claim, as the website offers both evidence from a mathematical model and evidence from a text written by a reputable source. This offers an opportunity to connect with the Common Core standards for reading and writing in science. Students could also “dig into” the model to see what happens when they enter different weights. They could, perhaps, gather enough evidence to graph the relationship between weight entered and weight of the world (weight of the world is given when you click on the picture of that world). This could even be followed up by giving the students some fictional planets' radii and masses, and having the students calculate their weights on the fictional planets.
