In this module Activity 3 investigates When atoms get close to each other, what happens to their potential energy? This activity applies energy concepts to compare the potential energy of atoms that are bonded as molecules with the...

In this module Activity 2 investigates What holds the atoms of a molecule together?The activity will explore what holds atoms together and why they from a molecule. Bonus reading includes Same Molecules but Different Representations.

In this Activity 1 investigates What makes materials different from each other? Students will continue to learn about energy and to investigate how energy changes relate to changes in matter. Students will also explore what makes...

Students explore connections between electric forces and molecules using simulations, and explain energy transfers using conservation of energy. This concept will be explored in the following activities. Activity 1 What makes materials...

Activity 4 of this module investigates Why do I get shocked if I am too close to the Van de Graaff generator? This activity explores what happens to the potential energy of a system when objects are allowed to move freely (not held in...

Activity 2 investigates Why is water different from other liquids? This activity will investigate properties of different liquids. Students will explore what makes honey gooey and thicker than water. And why some liquids evaporate faster...

Activity 2 investigates Why is water different from other liquids? This activity will discover the properties of different liquids. Students will explore what makes honey gooey and thicker than water. And why some liquids evaporate...

In Activity 1 investigates How are water and other liquids similar and different? The student will see if ideas involving energy, electrostatic interactions, and atomic structure, can be used to explain why a hurricane is so powerful.

Activity 2 investigates How Hot Can Water Get? In Activity 2 students analyze the relationship between energy changes and phrase changes as they discuss what happens when water boils. Bonus reading includes Why is Temperature Constant...

Activity 1 investigates What does boiling do to water molecules? In this activity students will collect evidence to analyze what happens to water during boiling.

In this investigation students will add energy to the model of how molecules interact by completing the following activities. Activity 1 What does boiling do to water molecules? Activity 2 How hot can water go? Activity 3 How does energy...

Activity 4 investigates How does electron distribution impact our observations? Students have described how properties of molecules change depending on what atoms make up the molecule. In this activity students will use those ideas to...

Students will develop explanations connecting observations of water with properties that water exhibits through the following activities. Activity 1 How are water and other liquids similar? Activity 2 Why is water different from other...

In this activity, students perform a reaction with different concentrations of reactants and monitor the temperature of the reaction. Activity contains procedure, analysis questions, and graph template. Students can save their answers...

Adjust the mass of one of the balls to see how the other objects are affected in the animated Newton's Cradle.

Experiment to see how air resistance affects the periodic motion of a mass on a spring.

Observe how friction affects a mass connected to two springs that are on opposite sides of the mass. Create a graph while the friction is on or off.

See how motion is converted and the energy associated with the motion is used to do work.

View the conversion of linear motion to rotational motion.

Observe the motion of this animated system to represent an analogy for molecular mechanics of atoms and molecules.

Adjust the elasticity and mass of a rope suspended between two points to see how it will be affected by gravity.

Watch how the placement of two weights attached to a chain on different sides of a pulley affect the movement of the system. You can adjust the heaviness of the weights.

Watch as two particles move through a confined area. The emphasis is on their motion in a straight line until they encounter a barrier and are reflected off in a different direction.
