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.

Matrices help solve systems of equations in chemistry, computer graphics, circuitry, probability, and more. The second lesson in a seven-part series focuses on using matrices to balance chemical equations. Pupils rely on the Law of...

Scientists require specific chemical solutions for their experiments. In the seventh and final installment in a series that integrates chemistry and algebra II, scholars learn to set up a system of equations to solve the volume of a...

Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...

Scholars apply concepts learned in both Algebra II and Chemistry to answer the questions on the provided worksheet. The activity allows for extra practice in both classes and helps connect concepts usually taught in isolation. The...

Several factors affect the rate of a chemical reaction including temperature, surface area, and concentration. Using an experimental approach, learners explore the effect concentration has on this rate while maintaining consistency with...

When it comes to rating educational calculators, this calculator is always near the top of this list. Now it's available as an app. There is a lot of calculator power wrapped up in this app. Not only is this a fully functioning...

How fun would it be to teach the concept of stoichiometry while allowing your chemistry class to assemble a classic campfire treat? This fun and engaging activity allows pupils to explore the principles of the chemical theory while...

Instructions for series of six activites, a reading of scientific literature, and a choice of six assessments await you in this physics resource. Well-written plans guide you in guiding your pupils to experiment with levers, pulleys,...

Whoa! What just happened? That's right, change is everywhere. But what exactly is changing? Middle school science sleuths get to the bottom of the changes matter can experience. Through simple demonstrations, engaging videos, and an...

If I want to build up my heart, where should I start? Science scholars use statistics in a sports physiology setting during an insightful experiment. Groups measure resting and active heart rates and develop a scatter plot that shows the...

Slip sliding away. Groups investigates the two types of friction by running an experiment that allows them to calculate the coefficient of static friction and the coefficient of kinetic friction. The experiment uses a box, a...

High schoolers conduct an experiment using the reaction of hydrogen and oxygen. After pairs balance the chemical equation for making water, they mix different ratios of hydrogen and oxygen in a chemical reaction. Classmates...

After an explanatory introduction to sugars and enzyme activity, biochemists discover whether lactase is needed to digest lactose, sucrose, and milk as a whole. High school science lab skills are required for these investigations.

Groups explore illumination with NASA's Lighting Environment Test Facility (LETF) as a context. Using the TI-Nspire app, groups determine the lux equation that models their simulation. They then use the lux equation to...

Prove the Law of Conservation of Mass through a lab investigation. A well-designed lesson asks groups to combine materials and monitor indicators for chemical reactions. Measuring the mass of the reactants and products allows individuals...

How temperature affects the efficiency of a solar panel is the focus of the third in a series of eight resources that presents how engineers are able to control the temperatures of photovoltaic panels. Class members find out how the...

Become an immunologist for the day. Scholars elicit the use of the enzyme-linked immunoabsorbent assay (ELISA) to diagnose an infectious disease. Through the process, they learn about the immune system response to infectious diseases.

To go or to not to go — the question for a mission to Mars. This resource provides details for a possible manned mission to Mars. Details include a launch schedule, what life would be like on the surface, and how the astronauts would...

What does the ground around your home have to do with water pollution? Young ecologists learn about their local watershed and create their own cause-and-effect models of the hydrosphere.

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...

Knowing the temperature coefficient allows for the calculation of voltage output at any temperature. Groups conduct an experiment to determine the effects of temperature on the power output of a solar panel. The teams alter the...

High school physicists demonstrate Bernoulli's Principle by blowing on different items and finding that they do not move in the expected direction! They apply Bernoulli's equation to the flight of an airplane. This well-organized...

Sometimes the best view is from the farthest distance. Satellite imaging makes it possible to create altitude maps from far above the earth. A three-part activity has your young scientists play the role of the satellite and then use...
