In this activity students test a variety of liquids and solutions to see which conduct electricity. Note: This is designed for use in a science museum or education center and may need to be modified for classroom use.

In this activity, students will study how temperature and concentration affect reaction rates and then design a procedure to get the reaction to occur in a specified amount of time. This activity is meant to be used as a performance-based assessment. Detailed student instructions, handouts, and a grading rubric are included.

Watch your solution change color as you mix chemicals with water. Then check molarity with the concentration meter. What are all the ways you can change the concentration of your solution? Switch solutes to compare different chemicals and find out how concentrated you can go before you hit saturation! Review teacher-submitted activities for ideas on embedding this interactive into lessons.

Students use manipulatives to represent visually the steps they take to obtain a solution to an algebraic equation. They develop an understanding of the connections between the solution involving manipulatives and the symbolic solution.

This resource is part of Tools4NCTeachers.This resource provides suggestions for integrating writing into the math block, while working with standard 1.G.3.

This file contains a set of word problems of varying problem types (each housed on its own recording sheet). Students discuss solutions orally with partners, then record and justify their solutions.

There are a variety of proposed solutions for reducing the impacts of climate change. Students research one of their choosing and compare it to the planting trees.
