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...

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 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 lesson includes specific dialogue and steps for the teacher...

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

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...

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

Learners explore the causes of differences in density. Students choose objects, measure the mass and volume, and calculate the density of each. They perform additional density experiments to model atoms and their correspondence to...

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...

Learners verbalize a simple particle theory, They apply their particle theory to explain what happens during chemical reactions and how this theory supports the law of conservation of matter. Pupils comprehend that the atomic theory,...

Students study how to write chemical fomulas by reviewing the combinations atoms form into compounds. They write a procedure to test various substances and name the compounds and write formulas. As they construct models for formulas and...

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

Students determine what plasma is and why the sun is made up of plasma. They recognize situations where plasmas are found in nature and made by man. They discuss why the sun is a huge ball of plasma and if there are different levels of...

Lead your class through the amazing world of isotopes as they investigate the various properties they contain and further understand their respective location on the periodic table. They explore half-lives and radioactivity as each...

Facilitate learning by using small objects to teach the principles of atomic mass in your science class. Pupils determine the average mass of varying beans as they perform a series of competitive experiments. They gather data and...

Fifth graders investigate the structure of matter. They examine pictures of atoms and molecules and discuss their relationships, and construct a model of a molecule using toothpicks and gumdrops.

In this early history of the atom worksheet, students answer 4 questions about Thomson's Plum Pudding model of the atom and Rutherford's experiment that led to the understanding of some of the structures of the atom.

In this periodic table worksheet, learners answers 10 fill in the blank questions by reading information form a periodic table. Then also complete Bohr Models of the atoms of 12 different elements.

For this atom worksheet, students read about the model of the atom developed by Neils Bohr. Students complete 2 short answer questions based on what they read.

Students explore what causes differences in density. They observe an models depecting atoms, compounds, and molecules. Students determine if there is air in between atomic bonds. They study the structure and spacing of molecular bonds.

View molecular structure for various compounds with three-dimensional color images.
