Students learn about acids, bases, and pH levels as they interact with the various features of this simulation.
How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?
Watch alpha particles escape from a polonium nucleus, causing radioactive alpha decay. See how random decay times relate to the half life. Java required.
Via this interactive SIMS experiment, students will grasp better understanding of decay in alpha particles and their relationship to half life. Lessons and teacher tips included.
Learn how to calculate area with this online game where you can choose to practice finding area and/or play a game. You can choose your level and whether you want to time yourself for an extra challenge!
Create shapes using colorful blocks, and explore the relationship between perimeter and area. CCSS.Math.Content.3.MD.C.7.a Find the area of a rectangle with whole-number side lengths by tiling it
Remember your multiplication tables? Practice your multiplication, division, and factoring skills with this exciting game. No calculators allowed!
This interactive simulation allows learners to drill the multiplication tables. This activity will also provide a good understanding of factoring and dividing.
Explore the interactions between various combinations of two atoms. Turn on the force arrows to see either the total force acting on the atoms or the individual attractive and repulsive forces. Try the "Adjustable Attraction" atom to see how changing the parameters affects the interaction.
Explore the interactions between various combinations of two atoms. Observe the the total force acting on the atoms or the individual attractive and repulsive forces. Customize the attraction to see how changing the atomic diameter and interaction strength affects the interaction.
Learn about balance by placing objects on a playground teeter totter. Take the challenge to show what you learn.
Play the Balance Challenge game to see how various objects can be used to make a plank such as a teeter totter balance and how changing the position of an object will affect the motion and tilt of the plank.
How does one know if a chemical equation is balanced? What can be changed to balance an equation? Play a game to test ideas!
An interactive simulation with weights and scales that teaches about balancing chemical equations and conservation of mass. This simulation can either be downloaded or played online and includes handouts, lesson plans, and additional materials.
Experiment with a helium balloon, a hot air balloon, or a rigid sphere filled with different gases. Discover what makes some balloons float and others sink.
Students studying buoyancy will better understand its concepts with this virtual experiment using various balloons and testing what makes them float or sink.
Investigate static electricity by rubbing a balloon on a sweater and observing what happens. Try it with two balloons. See the positive and negative charges that illustrate why there is attraction or repulsion between the balloons, the sweater, and a wall.
An interactive simulation with balloons and a sweater that teaches about static electricity, electric charges, and electric force. This simulation can either be downloaded or played online and includes handouts, lesson plans, and additional materials.
Explore the origin of energy bands in crystals of atoms. The structure of these bands determines how materials conduct electricity. Java required.
Test the pH of everyday liquids such as coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Investigate how adding more of a liquid or diluting with water affects pH.
