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...

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...

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...

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...

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...

Students explore the concepts of rotational equilibrium. They examine the history Alexander Calder and his mobiles. Students solve simple algebraic equations. They predict, draw conclusions, graph equations and examine the rotational...

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...

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 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 build and program a Lego Mindstorms Roverbot to travel for a given amount of time. They gather data on time versus distance traveled to determine a calibration constant for their robot, which relates time to distance.
