For this single variable equations worksheet, students solve 5 problems using different equations to solve for one unknown. They use Hubble's Law to find the velocity of a galaxy knowing the distance it travels.

Always strive to make things better. The second of three activities in the Experimenting with Solar Heaters unit has learners design new solar heaters that are more effective compared to the simple models they used in the previous...

Many high school science courses rely on mastery of algebra skills. In an integrated chemistry and Algebra II lesson scholars review solving equations for a specified variable with a worksheet. They use common chemistry equations to...

If I change the length, will they work better? After brainstorming the variables of wind turbine blade design, groups choose one variable to isolate and test. The groups then present their data to the class in order for all to have the...

If changing one variable can improve a design, why not try changing more? Using the results from the previous activity, scholars decide on the variables that caused the most improvement in the effectiveness of the solar heater. They take...

Students explore experimentation as a method for solving problems. In this movement lesson plan, students observe marbles rolling down a ramp, identify variables that could cause the marble to roll faster or farther, test changing one...

Why are gym walls padded and cars required to have air bags? Scholars observe two similar situations, such as those listed above, with only one variable altered. They identify the different variable and determine how the variation...

The process for balancing chemical equations is stepped through slide by slide in this presentation. For some strange reason, the subscripts for certain elements are not dropped down on the first slide only, so you may want to copy the...

Why did Mr. Ohm marry Mrs. Ohm? He couldn't resistor. An electrifying simulation allows scholars to control both voltage and resistance in order to see the current change. The formula is displayed and as you increase one variable, it...

Change one variable and try again. Teams build basic balsa gliders and collect data on their flight distances and times. Through collaboration, the team decides on two modifications to make to the basic design and collect data for the...

In this density instructional activity, students review how to rearrange the equation for density to solve for mass or volume. Then students complete 4 problems.

In this control and experimental variables worksheet, students read about the variables in an experiment and practice identifying each in 2 experiments. Students analyze the data in an experiment, identify the hypothesis and the...

Seventh graders identify variables and controls in a paper airplane investigation. For this scientific method lesson, 7th graders conduct an experiment to determine the variables that affect the flight of paper airplanes. They design an...

In this system of equations worksheet, students solve 2 problems by creating a system of equations for each problem in order to determine the average intensity of flares from the sun and the average power from a satellite transponder.

Using simple materials, an informative lesson demonstrates the Law of Conservation of Matter and explains how to balance chemical equations. Young chemists perform experiments, analyze reactions, and balance chemical equations...

Word problems can make even expert mathematicians go blank. Practice solving word problems with an extended version of the GUESS method (givens, unknowns, equations, solve, substitute), which adds the steps of drawing a diagram, making...

Provide young biologists with everything they need to excel in the study of lymphatics, the nervous system, hormones, cellular division, and more! Pupils utilize the workbook, complete with end-of-chapter assessment worksheets, to...

More of a math lesson plan than physics or space science, high schoolers take a set of data and plot it on a log-log coordinate system. The write-up for day two was never completed, but day one, "Stars and Slopes," is complex and...

High schoolers recognize different consumer products, found in and around the home, that have reactive or denaturing properties when used together. They explore chemical and physical properties of each product by identifying chemical...

A comprehensive practice exam, this resource covers many areas of chemistry. The test includes 71 multiple choice questions on topics such as problem solving, chemical equations, chemical formulas, thermodynamics, acids and bases, and...

Friction leads to movement, heat, and melting on such a small scale most people don't notice. A short simulation permits scholars to observe the reaction between atoms as they move together.  The simulation applies the concept of...

In this electric circuit worksheet, learners use Algebraic equations to manipulate the electrical resistance of a conductor. The answer a series of 19 open-ended questions. This worksheet is printable and the answers are revealed online.

A chemistry lesson presents 14 chemical reactions for scholars to observe, write the equation, and balance the equations. Additionally, it provides ways to extend the activity as it relates to catalysts.

The heat of vaporization, pressure, and boiling points are the topics covered in these calculations. Four questions give some of the variables and ask for the missing information. You could use this worksheet to work through as a whole...
