We already know that Rapid Climate Change is happening, but how bad could it get? The answer lies with us, human beings. That's because the decisions we make now will determine if the effects of Rapid Climate Change are mild or extreme. Scientists who study the climate tell us that if we continue to add carbon to the atmosphere at the current rate, the Earth will get a lot warmer in the coming years and decades. They use big, brainy computers to simulate what the climate will look like in the future.

This teacher resource guide will help teachers present the "Climate of the Future is in our Hands" video in their classrooms.

This task has students apply their knowledge of parallel lines to solve a geometric problem on areas of triangles.

An important property of linear functions is that they grow by equal differences over equal intervals. In this task students prove this for equal intervals of length one unit, and note that in this case the equal differences have the same value as the slope. In F.LE Equal Differences over Equal Intervals 2, students prove the property in general (for equal intervals of any length).

Linear functions grow by equal differences over equal intervals. In this task students prove the property in general (for equal intervals of any length).

In this task students prove that linear functions grow by equal differences over equal intervals, and that exponential functions grow by equal factors over equal intervals.

Examples in this task is designed to help students become familiar with this language "successive quotient". Depending on the students's prior exposure to exponential functions and their growth rates, instructors may wish to encourage students to repeat part (b) for a variety of exponential functions and step sizes before proceeding to the most general algebraic setting in part (c).

In this lesson, based on the Annenberg Classroom video âYick Wo and the Equal Protection Clause,â students explore the cause-and-effect relationships between historical events and the development of constitutional principles that protect the rights of all people in America today. The words inscribed on the U.S. Supreme Court building are a reminder of that protection: âEqual Justice Under Law.â

This lesson asks students to analyze a historical claim made on Twitter about the Equal Rights Amendment and to use the internet to investigate whether the claim is reliable. To begin, use the Equal Rights Amendment PowerPoint to introduce the tweet and provide students with historical context for the ERA. Note: A free educator account is required to access these materials.

Explore what it means for a mathematical statement to be balanced or unbalanced by interacting with objects on a balance. Discover the rules for keeping it balanced. Collect stars by playing the game!

This task helps students understand the meaning of the equal sign and to use it appropriately.

Learn about graphing polynomials. The shape of the curve changes as the constants are adjusted. View the curves for the individual terms (e.g. y=bx ) to see how they add to generate the polynomial curve.

Open Middle provides math problems that have a closed beginning, a closed end, and an open middle. This means that there are multiple ways to approach and ultimately solve the problems. Open middle problems generally require a higher Depth of Knowledge than most problems that assess procedural and conceptual understanding.

This task asks students to use inverse operations to solve the equations for the unknown variable, or for the designated variable if there is more than one.

This task asks students to use inverse operations to solve the equations for the unknown variable, or for the designated variable if there is more than one. Two of the equations are of physical significance and are examples of Ohm's Law and Newton's Law of Universal Gravitation.
