A great way to learn about molecular structures is to make a model. Gumdrops and toothpicks are used to construct crystal models. The models are based on theories of crystal shapes that occur because of positive and or negatively charged...

In a simple activity, physical scientists model nuclear fission using a droplet of oil. This can be used alone in a unit on different types of energy, or as part of the energy conservation unit produced by the Texas State Energy...

Explore the excited states of atoms through an interactive lesson. Scholars adjust the initial speed of atoms and observe the kinetic energy of the system as the atoms interact. As they change the initial speed and location of the...

Things are about to heat up in your classroom! A kinesthetic lesson asks learners to play the part of the gases in the earth's atmosphere and interact with the sun's radiation. The focus is to learn the impact of the increasing...

In this atom worksheet, students explain how different scientists added to our knowledge of the atom, specifically the structure and parts of an atom. This worksheet has 4 matching and 5 short answer questions.

Students list the names and symbols of common elements. They describe the present model of the atom. Students describe how electrons are arranged in an atom. They identify quarks as particles of matter that make up protons and...

Students investigate how information about the atom has been determined. In this atomic structure lesson, students draw what they think an atom looks like. They conduct Internet research about the types of atomic models and how...

Eighth graders study the conservation of matter.  For this chemical reaction lesson students examine what happens during a chemical reaction and complete a lab activity. 

Eighth graders explain what makes up matter.  In this atoms lesson students define an atom and what its components are and identify properties of elements. 

Young scholars analyze the way atoms function and how they combine to form molecules and various compounds. Using a software program, they create a diagram of an atom and write a summary about their functions. They complete a worksheet...

Students investigate the concept of elements and atoms. They conduct research using a variety of resources and use the information in order to create a class presentation. The instructional activity includes specific dialogue and steps...

Students examine a PowerPoint production on molecules. Then they construct their own molecule and define what an atom, molecule, and matter is. They make a H2, HCI, and an H2O molecule. Finally, a drawing to accompany the actual model is...

A two-hour final exam covers a range of physics topics related to electricity and magnetism. It employs a variety of methodologies for assessing your physics learners' understanding and mastery of these concepts. You will need to review...

Thanks to this game, teaching isotopes will never be the same. Physical science scholars work their way toward understanding isotopes in an entertaining game. Pupils play rummy in groups while practicing good sportsmanship and creating...

Build learning by breaking atoms! Young scientists study the way energy changes with a hands-on activity. As they roll steel marbles down a ramp, learners test the hypothesis that kinetic energy does not go away with friction...

I can move about freely, but you cannot. The class models the movement through cell membranes by way of passive and active transport. Members of the class play the roles of various proteins, atoms, compounds, and cell actions and mimic...

Did you know that jumping spiders sometimes wear water droplets as hats? A seventh grade science lesson introduces the concept of what makes up water: tiny molecules that are attracted to each other. Starting with a...

Get to you know your new class members with an ice breaker activity that uses their name and creativity. Scholars write their first name in cursive on a folded sheet of paper, cut around the curved lines, open the paper to view its new...

Viewers learn how to identify the substances in a chemical reaction, how to balance it, and the different types of chemical reactions by watching a presentation that also includes a review of monomers and polymers. The presentation...

Let the star's color be the guide! The color of a star indicates its temperature and its mass and distance affect the gravitational force. The lesson presentations address these concepts as well as how the theory of special relativity...

Simple in format and standard in content, this resource is an assessment of your beginning chemists' grasp of the atom. Using a periodic table of elements, they fill in a chart of missing chemical formulas, atomic masses, and numbers of...

Eighth graders explain the development of the atomic model over time. In this chemistry lesson, 8th graders research about the scientists who made a contribution to the atomic theory. They create a three-dimensional model based on their...

Students compare and contrast how the theory of atomic structure has changed over time. They explore how different people have contributed to our knowledge of the atom and its structure. Students identify how matter is made of discrete...

In this atomic models quiz learning exercise, students complete an on-line quiz, clicking on questions and matching answers, scoring 1 point for each correct answer. A printed version is available.
