8.EE.7 Solving Equations Quiz. Two versions. M is the standard version M1 is the modified version with simplified negatives and smaller multi-step equations. Both versions contain fractional problems too.

NCM1.A-REI.3 Solving linear equations and inequalities in one variable to include fractions.

In this activity, student teams create a knowledge map of the essential characteristics or factors of a planet with a habitable climate, identifying range of inputs, outputs and variables of a planetary environmental system. Identified characteristics are compared to extreme environments on Earth, such as the Antarctic or the Sahara desert, and are used to consider the real life challenge of searching for life in extreme environments. The resource includes a student data sheet, questions, teacher's guide and scoring rubric. This is Activity B of two activities in the first module, titled "Temperature variations and habitability," of the resource, Earth Climate Course: What Determines a Planet's Climate? The course aims to help students to develop an understanding of our environment as a system of human and natural processes that result in changes that occur over various space and time scales.

In this lesson, students encounter a situation in which they must solve for the value of a variable. The equations are in the form of p = qx, in which q, x, and p are all whole number values. This CYBERCHASE activity is motivated by an episode in which the CyberSquad plays a game against Hacker to catch enough "gleamers" to power up the Cyberspace ship. If they win, they get the Encryptor Chip. But first, they must figure out the relationship between gleamers and power glows.
