In this single variable equations worksheet, high schoolers 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...

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...

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...

Keep everything under control. The instructional activity, the 16th segment in a 22-part unit, provides a more detailed look at the parts of a plane, specifically the control surfaces. Pupils learn about the construction of the wings and...

Many high school science courses rely on mastery of algebra skills. In an integrated chemistry and Algebra II lesson plan 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...

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...

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.

Which modification is the best? Using the scientific method, pairs determine the effects of each control surface on the distance of a glider's flight. The activity, section 16 in a 22-part unit on aviation, allows pupils to gain a better...

A chemistry lesson plan 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 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...

Students explore Literal Equations. In this literal equations lesson, students use the Internet to connect to links and solve linear equations. Students investigate, analyze and record their findings on various activity worksheets.

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

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...

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...

Seventh graders identify variables and controls in a paper airplane investigation. In 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 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...

In this science instructional activity, students examine the topic in order to solidify knowledge covered in the curriculum using puzzles and creative games.

In this Drake Equation worksheet, students read about how scientists can estimate the number of intelligent civilizations that may exist in our galaxy. Students answer 7 questions about the Drake Equation and they use the internet to...

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...

It's the law—every action requires a reaction, no matter how small. Pupils experience two demonstrations of Newton's third law of motion as it relates to thrust in the 10th segment of a 22-part unit on flight. Using their mathematical...
