Explore how electricity splits water molecules into hydrogen and oxygen. Learners begin by calculating the voltage necessary to separate the water. They then perform the experiment and measure the ratio of hydrogen and oxygen bubbles.

Sometimes being different is an advantage. An engaging activity has scholars match cards with quadratic functions in various forms. Along the way, they learn about how each form highlights key features of quadratic functions.

How does sound travel through different mediums? Scholars explore this question by creating and observing sound waves as they learn the difference between transverse and longitudinal wave motion. Using their new knowledge, class members...

De-icing materials may have a harmful effect on our environment; have your class perform an experiment to test the nature of these effects. Scholars monitor the survival rate of a sample of daphnia as the concentration of a de-icing...

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...

Stability is key when building a bridge. Scholars explore the forces acting upon bridges through an analysis of Newton's Laws and Hooke's Law. The activity asks individuals to apply their learning by building a bridge of their own.

The size of a nanoparticle is difficult for pupils to grasp. A hands-on experiment is designed to give your classes perspective. Learners analyze different sports drinks for the content of electrolytes as an introduction to nanoscale....

Scholars are sure to get a charge out of an electric lesson! They examine the potential energy of charged particles while they make changes to the electrical field. The simulation allows them to change the position of particles and the...

Does the charge on a particle affect its energy? Scholars first explore how the strength of a charge affect the potential energy. They observe the change in the electric fields as this potential energy changes.

Explore the relationship between the distance and the force of charged particles. Scholars adjust the location of charged particles to change the path of a launched particle. By displaying the electric field, they can make a connection...

Build an electric field to direct a charged particle to a target. Scholars determine how location and strength of charge affect the electric field that surrounds the object. They complete two challenges to strengthen their understanding.

Challenge your classes to use electric fields to hit a target. Scholars place positively and negatively charged particles on a game board to direct a charged particle to a target. They can choose to view the electric field and force on...

Why do different substances have different boiling points? Through an interactive lesson, learners explore how intermolecular attractions affect boiling points. They interact with molecules through an animation and make conclusions about...

How is a mean affected by changes in data? A well-designed animation allows individuals to manipulate data and watch the effect on the mean. Challenge questions help guide users to conclusions about outliers and skew within data.

Learning isn't a random process. A well-designed interactive lesson helps classes make key conclusions about stratified random sampling. They calculate group percentages and use those percentages to decide on sampling totals.

Teach the concept of simple random sampling through an interactive lesson. Learners explore the concept by considering the strength of sampling methods. Size of the samples varies also as individuals determine which methods lead to the...
