Create your own shapes using colorful blocks and explore the relationship between perimeter and area. Compare the area and perimeter of two shapes side-by-side. Challenge yourself in the game screen to build shapes or find the area of funky figures. Try to collect lots of stars!
PhET Interactive Simulations
Remember your multiplication tables? ... me neither. Brush up on your multiplication, division, and factoring skills with this exciting game. No calculators allowed! The students will be given mutiplication and division problems which they must answer. They also have the option of being given a number then stating the factors of how that number was attained using either multiplication or division.
This lesson plan is designed to accompany the PhET interactive simulation "Balancing Chemical Equations." Teacher notes / lesson plan outline and student handouts are included.
This interactive resource provides student practice in balancing chemical equations. Atomic models are shown to help students understand that the number of atoms are conserved during the reaction. There are three progressive levels of practice activities. Review teacher-submitted activities for ideas on embedding this interactive into lessons.
With this interactive resource, students will learn about static electricity and observe the interactions of charges between a sweater, balloons, and a wall. The main information page for this resource offers a link to a teacher's guide and other suggested resources.
With this interactive resource, students can practice building models of neutral atoms and ions. Atoms can be viewed as a Bohr model or electron cloud model. Students can review information from the periodic table for each atom as they build it. The associated game serves as an assessment of the concepts reviewed through the practice portion. The main information page for this resource offers a link to a teacher's guide and other suggested resources.
Investigate collisions on an air hockey table. Set up your own experiments: vary the number of discs, masses and initial conditions. Is momentum conserved? Is kinetic energy conserved? Vary the elasticity and see what happens.
With your mouse, drag data points and their error bars, and watch the best-fit polynomial curve update instantly. You choose the type of fit: linear, quadratic, cubic, or quartic. The reduced chi-square statistic shows you when the fit is good. Or you can try to find the best fit by manually adjusting fit parameters.
Students will use the simulation to develop a general knowledge of distance-time graphs. Basic graphing skills are needed to complete the activity. This lesson plan accompanies the PhET simulation, "Moving Man."
How many calories are in your favorite foods? How much exercise would you have to do to burn off these calories? What is the relationship between calories and weight? Explore these issues by choosing diet and exercise and keeping an eye on your weight.
This lesson plan accompanies the PhET simulation, "Eating and Exercise." Students can manipulate variables such as age, height, and body fat composition and compare the effect on weight of varying ratios of caloric intake to calories burned. Students will then use this information to explain which variables affect BMI and which do not. They will also investigate how dietary changes affect weight and overall health.
This lesson plan accompanies the PhET simulation, "Electric Field of Dreams." In this activity, students will visualize the effects of the movement of one or more negative charges across an applied external field. They will also explain the relationship between the size and direction of the electric field to the sign and magnitude of the charge of a particle.
This lessonplan accompanies the simulation "Faraday's Electromagnetic Lab". Students will use the simulator, in which they can manipulate a magnet, compass, and electromagnet, to answer questions about polarity, Faraday's Law, electric fields, transformers, and generators.
This lesson plan accompanies the PhET simulation "Electricity, Magnets, and Circuits". Students will answer basic questions about electrostatics. Students will then use the simulator to manipulate positive and negative charges and answer questions about electric fields and field diagrams. There are real-world applications students will research and an air hockey style game students play with a simulator using electric charges to score goals.
Learn about conservation of energy with a skater dude! Build tracks, ramps and jumps for the skater and view the kinetic energy, potential energy and friction as he moves. You can also take the skater to different planets or even space!
Explore what it means for a mathematical statement to be balanced or unbalanced by interacting with objects on a balance. Discover the rules for keeping it balanced. Collect stars by playing the game!
Learn about graphing polynomials. The shape of the curve changes as the constants are adjusted. View the curves for the individual terms (e.g. y=bx ) to see how they add to generate the polynomial curve.
This lesson plan accompanies the PhET simulation, "Reversible Reactions." The instructional goals for this lesson are for students to understand that equilibrium is reached at the most stable ratio of reactants and products, and that when stress is placed on a system at equilibrium, the system acts in a way to counteract the stress and restore equilibrium. In this lesson, the teacher leads whole-class instruction through demonstrations and implementation of simulation. Student handouts are provided.
In this interactive simulation, students manipulate a bar magnet and coils to learn about Faraday's law. Moving a bar magnet near one or two coils will make a light bulb glow. There is an option to view the magnetic field lines. A meter shows the direction and magnitude of the current.
