Learners write the electron configuration of elements in the ground state. In this chemistry instructional activity, students draw how subatomic particles are arranged in the atom. They construct Lewis dot diagrams of valence electrons.

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.

Ninth graders explain how atoms and molecules form different substances during chemical reactions and how these processes require losing, gaining or sharing electrons. They correctly write chemical formulas and show how a balanced...

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.

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,...

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...

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...

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.

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.

For this physical vs. chemical change worksheet, high schoolers answer 10 questions about identifying chemical and physical changes. They identify exothermic and endothermic reactions and the parts of a chemical equation. Students answer...

For this science worksheet, students examine how the universe is bound with the atomic particles and focus upon the findings of two historical scientists.

In this atomic structure activity, students select answers to 8 fill in the blank questions on subatomic particles from the drop down box.

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

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.

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...

In this word search worksheet, students search for 32 hidden words found vertically, horizontally, backwards or diagonally. Words are words encountered during visits to "The Jefferson Labs."

For this cells learning exercise, students answer questions about the first person to see a cell as well as the evolution of microscopes. They define the parts of a cell and tell the differences between Prokaryotes and Eukaryotes. There...

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

Young scholars investigate elements by by defining scientific terms.  In this Periodic Table of Elements lesson, students utilize a glass of water, and powdered fruit drink to perform a lab activity demonstrating properties of...

Pupils observe the behavior of different charged objects. In this science lesson, students perform a series of static electricity experiments. They discuss their observations in class.

Learners investigate the atom and how it is formed. They conduct research using a variety of resources and then construct a model of the atom. Then students have class discussion. The lesson includes background information for the...
