Students observe water as it changes form.  In this water lesson plan students observe, measure, and describe water as it changes state. 

Students explain concepts related to static electricity, based on a single example: lightning.

Students reinforce the concept that static electricity is a phenomenon that involves positive and negative charges.

Students watch instructor present demonstrations of the basic principles of static electricity, and then conduct some of their own experiments. In small groups, students build simple circuits, using batteries, to try to light up a light...

Students examine water. In this chemistry lesson, student examine the physical properties of water and how it changes from a liquid to a solid or a gas. This lesson contains links to a second and third complimentary lesson on...

Students explore the properties of water and how it changes states. In this kindergarten to 2nd grade science lesson, students pair a hands-on science activity with two suggested books. This inquiry lesson has...

Students explore the nature and composition of a comet. They research comet facts, legends, and myths. They identify different types of comets and describe what happens to a comet as it travels closer to the Sun.

In this science puzzle activity, students solve a crossword puzzle related to matter. For example, "Scientist who discovered protons."

Students study magnetism. For this science lesson, students participate in an activity to discover how electrons in a magnet move. Students identify items around the classroom that are magnetic.

In this chemistry worksheet, students are provided with the answers to a 28 clue crossword puzzle about elements and compounds.

In this electricity and circuits worksheet, students read a 2 page article, answer 5 questions with multiple choice answers and read 10 statements and determine if they are true or false.

Trace the sequential process of the developing theories of atomic structure in the early 20th century, show, in historical development, how scientists "know" things, how experiments are set up and how interpretations are drawn from them,...

In this energy and nuclear power instructional activity, students, with a partner, discuss what thirteen energy terms mean and match those same terms to their definitions in the second activity.

In this elements worksheet, students determine the atomic number, mass, number, electrons, protons, and neutrons for elements. Students review the electromagnetic spectrum. This worksheet has 1 graphic organizer and 13 multiple choice...

In this radiation worksheet, students complete a crossword puzzle by figuring out the vocabulary terms associated with the 25 clues given.

Fourth graders compare electricity and magnetism. In this science lesson, 4th graders discuss the concepts of electricity and magnetism and brainstorm examples of electrical and magnetic forces.

In this chemistry review instructional activity, students explore their knowledge of solutions, acid and bases, nuclear reactions, and radioactive decay as they answer 33 matching, fill in the blank, and short answer questions.

For this stars worksheet, students read about the different stages in the life cycle of a star. Then students complete 3 short answer questions.

Students examine the atomic structure of elements.  In this chemistry lesson students organize elements of the periodic table according to their atomic mass, and compare their order within the periodic table. 

High schoolers describe how elements are arranged on the periodic table. They compare metals, nonmetals, and metalloids based on their properties and on their locations in the periodic table. Students describe the differences between a...

Fifth graders explore energy transfer. In this thermal energy lesson, 5th graders stretch rubber bands several times and estimate the band's temperature change. Students identify this action as an example of thermal energy. Students...

Learners read periodicals relating to radioacitivity and interpret a Geiger Counter. They work in small groups, share information and help each other explain the Geiger Counter. They discover the relationship distance to...

Young scholars use a video, the Internet and hands-on activities to explore how to determine the age of rocks and fossils based on radioactive decay data.

Students examine concepts of nuclear chemistry. They compare and contrast the topics of nuclear fission and nuclear fision. They predict the outcome of reactions based on the types of emissions and reactants.
