Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, young scholars build molecules based on the chemical formulas of common...

Students are able to discuss the difference between a proton, a neutron and an electron. They also can explain the difference between an ionic and a covalent bond. Students know the main structure of atoms and molecules. Student are able...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

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...

Show young chemists what a chemical reaction looks like with two parts of a hands-on experiment. First, learners conduct a wet lab where they observe the reactants (baking soda and calcium chloride, with phenolsulfonphthalein)...

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...

Fifth graders explore the differences between elements.  In this elements and atoms lesson students complete an activity that shows how chemicals react to a flame test. 

It's all relevant, really. Individuals use the scientific method to learn more about elements, atoms, and their placement on the periodic table. They conduct experiments using materials common in nature to explore how elements affect our...

Excited atoms lead to exciting lessons! Learners use heat and light to excite both atoms and molecules. They display their learning in the form of Bohr models depicting the excited state of the atoms.

Glucose is a simple sugar and a molecule that can be illustrated through modeling. Scientific investigators with visual impairments use hands-on models to reconstruct the process of bonding molecules. The tools used in this activity are...

Pupils examine the differences between elements, compounds and mixtures. Using diagrams, they compare and contrast atoms and molecules and describe various chemical reactions. They distinguish the differences between ionic and covalent...

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

Students explore many of the basic properties of matter including atoms, ions, elements, molecules, and density. The class explores an interactive flash-animated Web site to answer questions and clarify misconceptions they might have had...

Future chemists practice laboratory techniques by creating a monochloramine solution. The objectives are to use of dilution, 9concentration, and measurement skills and to prepare a solution that will be used in a water treatment...

Students watch video, The Elements, research information about elements using both the Internet and CD-ROM program, and create atoms out of gumdrops and licorice.

First graders discuss, at their level, the concept of elements making up all matter. They discover the story of Dimitri Mendeleev and his discovery of the Periodic Table of the Elements. They locate and color some of the most common...

Pupils explore the concept of atoms and how they combine to form molecules and compounds. In pairs, they read an article on how atoms work and discuss the main points. They draw atoms and write a paragraph about their elements.

Cookies and chemical equations have a lot in common! Using cookies as a reference, scholars learn to balance chemical equations. Pieces of the cookies represent different parts of the compounds and elements. This is the sixth installment...

For this making molecules worksheet, students complete a table of elements with their symbol, atomic number, atomic mass, number of protons, number of electrons, period and group. Students then make models using pipe cleaners and beads...

In this minerals worksheet, students read about the relationship between elements, rocks and minerals. They experiment using 6 different colored gumdrops to represent 6 common elements. Students construct gumdrop and toothpick models of...

Learners experiment to find which liquids are more dense.  In this density and mass lesson, students predict and then test objects to observe and measure their density. learners observe which items sink and float. Students complete...

Pupils are introduced to the elements on the Periodic Table and what is meant by element. Using the Table, they identify the name, atomic mass, number and symbol of each element. To end the lesson, they discover the characteristics of...

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...

Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for...
