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...

In this balancing equations worksheet, students are given directions as to how to balance equations and they practice what they learned. They complete three equations by placing the proper coefficients in front of the reactants and...

Stop wasting energy searching for physics resources, this comprehensive collection of worksheets has you covered. Starting with introductions to the scientific method, dimensional analysis, and graphing data, these skills practice...

Examples and practice questions will help real-life understanding of the Principle of Moments concept. These great slides define the types of levers and pivots, and then give examples of the typical seesaw situations that help the...

Two activities employ the use of kinematic equations for determining projectile ranges. They both require the use of a toy dart gun. Included in this resource are both the teacher's guide and student laboratory sheets. This is an...

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...

High schoolers determine the linear equations of the density of water and oil by collecting data on the mass of various volumes of each liquid. They construct scatter plots from the data and use these to write the linear equations for...

Young scholars determine how the weights of 7 objects on a seesaw can vary and still be in balance. They also write equations in algebraic terms, how to change 3 variables in an equation expressed in algebraic terms to obtain the correct...

Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical...

In this chemical reactions worksheet, students answer 20 multiple choice questions about chemical equations, chemical formulas, oxidation and reduction reactions and acids, bases and salts.

Students predict which of two glasses is 1/2 full using visual estimation, height measurement, and liquid measurement methods. Mathematical equations to accurately solve the problem are determined and verified.

Young scholars explore the concept of chemical formulas.  In this chemical formula lesson, students watch a video about balancing chemical equations.  Young scholars conduct an experiment using silver nitrate and sodium...

What came first, pedestrian one or pedestrian two? Scholars consider a problem scenario in which two people walk at different rates at different times. They must decide who reaches a checkpoint first. Their answers are likely to surprise...

In this magnetopause instructional activity, students use a given equation to find the distance from the Earth where the solar wind pressure and the Earth's magnetic field pressure are equal. Students are given 5 different solar storms...

In this estimating cell sizes worksheet, students read about the relationship between a cell's size and the rate of cell waste diffusion. Students solve 4 problems including writing the equation for the rate of waste exchange, finding...

Take the time and energy learn about Earth's energy budget. An engaging unit of four lessons focuses on the components that make up Earth's energy budget. Future scientists come up with a formula for the energy budget, then use software...

All sodium carbonate may not have the same amount of carbonate, but it should have the same percent. Learners write and balance an equation to predict the chemical reaction between sodium carbonate and zinc acetate. Through the lab...

Young scholars examine stoichiometry. In this chemical reaction and mole instructional activity, students complete an experiment based on readiness levels to explore that changes are quantified in chemical reactions.

In this mass of the Moon worksheet, students use the lunar orbit and the orbit period to determine the mass of the Moon. They solve 4 problems including finding the mass of the Moon, determining the ratio of the Moon's mass to the...

Students conduct an experiment in which a solution of copper(II) sulfate is added to iron filings. They write and balance the equation for the reaction that occurs and calculate the amount of iron that reacted and the percent yield of...

In this energy worksheet, high schoolers use the kinetic energy equation to solve for speed or mass. This worksheet has 11 problems to solve.

Students analyze velocity and how it is determined. They experiment with velocity in order to measure and calculate the magnitude of speed. They use examples in their novel "Skateboard Renegade" to relate velocity to real life situations.

Students compete in playground games in order to review velocity and wave behavior in real life situations. They demonstrate understanding by calculating velocity in their "Playground Games" packet.

Seventh graders simulate the capture-recapture method of population sampling using beans. In this biology lesson, 7th graders calculate the total population of beans in the bowl. They assess whether this method is reliable or not.
