Greatest Common Factor Using Factor Trees

For Students 6th Standards
Beginning with a description that sets the stage, learners are asked to break down the numbers 42 and 63 to find the greatest common denominator using factor trees. As they work through the factoring process, young mathematicians are...

Fraction Ordering with Lowest Common Denominators: Test Your Strength

For Students 6th Standards
Young mathematicians use a bell and hammer to see how high or low the puck goes. Then, they order the fractional values to demonstrate the greatest to lowest hit. Students then respond to several questions that require them to use...
Lesson Planet

Field Lines

For Students 6th - 12th Standards
The earth has a giant magnetic field caused by the liquid iron that constantly moves in the outer core. Scholars explore the magnetic fields of four different planets. The strength and alignment of the poles relates to the implications...

Touch Screen

For Students 6th - 12th Standards
Touch screens are becoming more common, but how do they work? The simulation shows the electric potential versus system charge as scholars alter three variables. The schematic of the capacitance demonstrates the set up as each variable...
Lesson Planet

Lightning-Rod

For Students 6th - 12th Standards
Why do some buildings have lightning rods? Scholars explore the movement and attraction of opposing electrical charges through a simulation of a lightning rod. They control the cloud height, charge separation, and if the lightning rod is...
Lesson Planet

Diamond Cut

For Students 6th - 12th Standards
How do jewelers tell the difference between diamonds, glass, and cubic zirconia? A sparkling simulation demonstrates how to use a ray of light to determine the substance and ideal shape for a diamond. Scholars control the material,...
Lesson Planet

Contact Lens

For Students 6th - 12th Standards
How do contact lenses work? The simulation allows young scientists to explore focal length and lens type to see how and why contact lenses work. Pupils control the focal length for an eye and a lens, the type of lens, and the distance...
Lesson Planet

Magnifying Glass

For Students 6th - 12th Standards
How can a magnifying glass or reading glasses make things appear larger? Scholars simulate moving a lens closer or farther from an object to observe the resulting image. They also alter the lens focal length. The simulation shows the...
Lesson Planet

Stadium Wave

For Students 6th - 12th Standards
If you are at a sports match and the crowd starts two waves that are both headed toward you at the same time, what do you do? The simulation applies the concepts of constructive interference and destructive interference to that very...
Lesson Planet

Ski Jump

For Students 6th - 12th Standards
What are the three types of energy a ski jumper uses? If you said potential, kinetic, and heat, then you are correct. Scholars adjust the jumper's mass, jumper's form, and height of the start line in the simulation to display graphs of...
Lesson Planet

High Energy Particles

For Students 6th - 12th Standards
How much energy is required to break apart an atomic nucleus and does it vary based on the type of atom? Scholars virtually experiment with a linear accelerator in order to answer these questions. They alter the voltage, length of the...
Lesson Planet

Hot Oven

For Students 6th - 12th Standards
Why does the air in a hot oven not burn skin, but metal in the oven does? The simulation focuses on the difference between temperature and thermal energy and the way these are transferred. Scholars adjust the temperature of an oven and...
Lesson Planet

Trampoline

For Students 6th - 12th Standards
Does a trampoline use mostly potential or kinetic energy? Pupils adjust the mass of the jumper, stiffness of the trampoline, and initial jump height in order to answer that question. The simulation displays graphs of the various types of...
Lesson Planet

Block and Tackle

For Students 6th - 12th Standards
Can you easily lift more than your own weight? With a pulley system, almost anyone can manage this challenge. Scholars adjust the mechanical advantage (number of pulleys), weight of object being lifted, and the length of rope pulled. The...
Lesson Planet

Roller Coaster

For Students 6th - 12th Standards
Roller coasters rely on both kinetic and potential energy, but how much total energy does a roller coaster need? Scholars vary the mass of a coaster and the height of the initial hill. Graphs showing the types of energy and total energy...
Lesson Planet

Unicycle

For Students 6th - 12th Standards
What is the steepness of a hill before a unicyclist slides down it rather than pedaling down it? The simulation graphs the wheel speed versus the unicycle speed as the rider goes down a hill. Scholars control the mass of the rider,...
