Students will investigate concepts related to endothermic and exothermic reactions and activiation energy. Students will construct and interpret an energy diagram showing the progress of an exothermic reaction.

Students will: determine the number of protons, neutrons, and electrons for a ...

Students will: determine the number of protons, neutrons, and electrons for a given element by using the periodic table; construct and draw models and diagrams of atoms; use the concept of the stable octet to predict simple molecular formulas; and distinguish between elements and compounds.

Students make observations of a ball bouncing off a hard surface one time or sequentially for several trials. From these observations students will then describe and explain the motion of the ball.

Students will explore several striking and unusual properties of bouncing superballs. They ...

Students will explore several striking and unusual properties of bouncing superballs. They will measure and understand the elasticity coefficient of a bouncing superball and understand the role of energy conservation in relation to bouncing balls.

Students will distinguish between reactions that go to completion and those that ...

Students will distinguish between reactions that go to completion and those that are reversible. Students will also explain the concept of chemical equilibrium and understand how Le Chatelier's Principle works on a chemical reaction at equilibrium.

Students review the basic characteristics of waves and recognize visible light as ...

Students review the basic characteristics of waves and recognize visible light as part of the electromagnetic spectrum. Students will also model electon energy levels and identify elements based on flame color.

Students will enhance their understanding of combustion using the reaction between dry ...

Students will enhance their understanding of combustion using the reaction between dry yeast and hydrogen peroxide. The eperiment demonstrates that certain things are needed for combution - especially oxygen.

This lesson reinforces concepts about atomic structure. Using their copy of the periodic table of the elements, gumdrops, toothpicks, a model wave three wavelengths long, and a calculator, each student will construct a correct model of the magnesium atom.

This lesson demonstrates that in a chemical reaction where a gas is ...

This lesson demonstrates that in a chemical reaction where a gas is produced, the mass does not change. Students will weigh an empty bottle, water, and a peice of antacid tablet, and then add the antacid tablet to water and close the bottle. When the reaction is complete, they will weigh the bottle again; then open the bottle to release the gas and weigh the bottle again. Students will communicate the results of the experiment in a written lab report.

Students will observe qualitatively the relationship between electrical charge and force and ...

Students will observe qualitatively the relationship between electrical charge and force and determine experimentally the quantitative relationship between force and the center to center distance between charged objects.

Students will be given a bag of materials and asked to find ...

Students will be given a bag of materials and asked to find out how a current-carrying coil is influenced by a magnetic field. They will also construct models of galvanometers and DC motors using film cannisters.

Students will demonstrate the difference between one-dimensional elastic and inelastic collisions. They ...

Students will demonstrate the difference between one-dimensional elastic and inelastic collisions. They will also calculate momentum of various balls colliding against three different surfaces and compare results with theoretical principles of conservation and energy. Students will record and graph data.
