The given solutions for this task involve the creation and solving of a system of two equations and two unknowns, with the caveat that the context of the problem implies that we are interested only in non-negative integer solutions. Indeed, in the first solution, we must also restrict our attention to the case that one of the variables is further even.
Material Type: Activity/Lab
In this activity, students explore reactions in which chemical bonds are formed and broken. Students experiment with changing the temperature and the concentration of the atoms in order to see how these affect reaction rates. They also learn how to communicate what happens during a chemical reaction by writing the ratios of reactants and products, known as stoichiometry.

If I create a module in OER Commons and tag with a standard, will the standard be pulled through when I use the LTI app in Schoology?

This unit provides Common-Core aligned lessons based for Math 3, English 10, and Biology (NGSS Standards). The subjects are linked by a text on climate change, and they hit the standards of argumentation for English, comparing functions in Math 3, and human effects on environment in Biology.

From Getting Smart, here are 12 ways to start teaching STEM Want more STEM experiences for your students but don’t know where to start? Want to infuse art into science and boost STEAM experiences? Before exploring how to do STEM, let’s define what it is. Everybody teaches science and math—STEM adds technology and engineering to the equation; STEAM adds art. Common elements of quality STEM learning include: • Design-focus: using design tools and techniques to attack big problems or opportunity (challenge-based, problem-based learning). • Active application: applying knowledge and skills to real-world situations and constructing or prototyping solutions to challenges (maker, project-based learning). • Integration: real world problems aren’t limited to a discipline—solutions almost always draw from many fields.
