In this chemistry worksheet, students determine the number of atoms in each element and select one that is not equal on both sides of the equation. Then they add a coefficient in front of the formula with that element and adjust their...

Students build simple mobiles. For this equilibrium lesson, students investigate the functions of three types of levers as they analyze artwork by Alexander Calder. Students then create their own simplified mobiles.

In this equations learning exercise, students solve one digit addition and subtraction problems and then put 2 problems on each scale that are related. Students complete 12 equations and put 8 scales together.

Ninth graders solve and balance equations. In this algebra instructional activity, 9th graders solve equations using the balance method. They divide, add, multiply, and subtract to solve for the unknown. They apply the concept of "what...

Students apply a traditional method when solving and balancing equations. In this algebra lesson plan, students organize their work showing each step they used to solve one and two steps equations. They solve equations with fractional...

The greenhouse effect is important, for without it, life on Earth would not exist. An activity that includes modeling the greenhouse effect and acting out the Earth's energy balance makes up the first part in a series of seven...

An overview of acid and base compounds and their reactions is presented with this handout. Pupils name compounds and write chemical formulas. They write net ionic equations and explain how acidic solutions might conduct electricity. This...

High school is the time that many scholars get their first jobs. Help young entrepreneurs apply economic principles to crucial skills for their new jobs and for functioning in society in general. They use Excel to balance a checkbook by...

Are there benefits to being physically active? Yes! There are both short-term and long-term benefits! Being physically active doesn't just have strengthen you physically, but also emotionally and socially. Learners find out how to...

Who were the absolute monarchs of Europe and what effect did they have on their countries? Young historians begin by naming qualities they believe are important for a monarch to possess. They then take notes on four key factors...

Not all interactives are made equal. Scholars use an interactive balance to explore the concept of equality. They place different objects on balances to determine the number of each object needed to balance the scale.

Experimental data for a chemical reaction is available in a table. Chemistry cohorts use critical thinking skills to analyze the data and answer questions about reaction rates and reaction order. This worksheet is neatly formatted,...

After breaking into groups according to major principles of government (i.e., popular sovereignty, separation of powers, checks and balances, etc.) in the United States, your class members will produce public service announcements...

Chemistry can help athletes and others protect and treat injuries. Use the interactive activity to explore the chemical reactions in instant hot and coldpacks. Learners manipulate the type of salt in the pack and watch the reaction take...

You're bound to get a reaction from your classes with this experiment! Scholars perform several chemical reactions, make observations, and classify the reactions as single replacement, double replacement, composition, or decomposition...

Two lessons promote starting the day with a balanced breakfast. Lesson one challenges scholars to create their own cereal after examining their current favorite cereal, including its nutrition facts. In instructional activity two,...

Let knowledge of chemistry flow like water. Future scientists conduct two different experiments to investigate the properties of water. They learn about surface tension and cohesion as they see how many drops of water they can place on a...

Fifth graders examine symmetrical and asymmetrical balance while making a mask using a variety of colored pencil and marker techniques. They use the process of revision and design as they complete their masks.

Seventh graders apply their prior knowledge of the Principle of Balance to create a paper mola. Students examine a variety of molas, which are fabric works of art made by women in the country of Panama. To arrange the composition of the...

In this Archimedes worksheet, students complete and respond to 4 different problems related to different triangles. First, they find the midpoint of each side of a given triangle. Then, students connect the midpoints with the opposite...

Seeming incomplete, this slide show introduces physical science novices to the balancing of forces and drawing force diagrams. The first seven slides work well to meet this purpose. The remaining slides, however, turn viewers over to...

How do grown ups do it? Teach your upper graders the ins and outs of personal finance by having them use their algebra skills to balance a checkbook. They examine the financial side of math, set up a checking account, and balance their...
