Venture into the world of macromolecules with three exciting, distinct laboratory activities. Young chemists examine the forms of carbon and discover how they are associated with atomic arrangement, construct models of carbon-containing...

Meteorologists view an animated video by the Environmental Protection Agency to learn how the carbon cycle works, and then move into groups to analyze and graph actual data of the atmospheric carbon dioxide concentration from Hawaii's...

Making models is always memorable. In this activity, physical science starters examine the structure of hydrocarbons using marshmallows, raisins, and toothpicks. They even act as atoms themselves and link arms to represent covalent...

In this chemistry worksheet, learners respond to several multiple choice questions relating to bonding and acid-bases. They also identify the various types of bases and how they differ from each other.

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...

Using toothpicks, marshmallows, and round colored sticky dots, physical science enthusiasts build models of an atomic nucleus. In this eighth grade chemistry lesson plan, they play an atom-naming game with the models that they have...

Students conduct a series of experiments to explore carbon dioxide properties. In this chemistry instructional activity, students explain the production and uses of this gas. They measure its amount in soda and waste product of yeast.

High schoolers investigate the carbon dioxide content of different sodas. In this chemistry instructional activity, students explain why PET containers are preferable than HDPE for soda bottles. They collect data and graph them.

So how does the carbon cycle work? Kids participate in a hands-on activity that allows them to understand the chemistry behind climate change and global warming. They act out the process of photosynthesis by labeling themselves as...

Students create a polymer using Borax and Elmer's Glue. In this chemistry lesson, students identify monomers made of hydrocarbons and then brainstorm a list of polymers and their uses.

Blend chemistry with cooking in this exploration of polymers, carbohydrates, and food science. Experimenting with gelatin produces concrete examples of the bonding and ploymerization discussed in the lesson. Copious, comprehensive...

Students work together to observe the bond lengths of single, double and triple bonds. They make their own predictions about the strength of the bonds and chemical reactions. They answer discussion questions to complete the lesson plan.

High schoolers 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...

Lost an electron? You should keep an ion them. Young chemists learn qualitative analysis in the second lesson of an 11-part chemistry series. After observing reactions of simple salts, the teacher provides pupils with unknown...

Students measure the temperature change involved in the production of carbon dioxide by yeast. They also identify products and reactants in a chemical and balance the equation.

In this chemistry review worksheet, students practice using Avogadro's number, calculating number of moles, and using the gas laws. This worksheet has 39 multiple choice questions.

Students examine the carbon cycle while identifying its sources, sinks, and release agents. Using magazines and newspapers, groups of students design collages illustrating the carbon cycle. Finally, they write responses to several...

High schoolers will draw Lewis structures of common covalent compounds using a Chem 3D computer program. They will predict the shapes of the molecules, complete a data table, and formulate rules for predicting shapes of molecules. In the...

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...

In this drawing Lewis structures worksheet, students read about the 5 steps taken to draw Lewis structures for atoms and molecules. These include identifying the valence electrons, placing pairs of electrons between atoms to be bonded,...

High schoolers cuminate their study of molecular structure and bonding with this activity.

Fifth graders study how respiration and circulation are connected.  For this respiratory lesson students complete several activities to better understand heart rate and carbon dioxide in the body. 

Students construct models of hydrocarbon molecules using candy and toothpicks. In this hydrocarbons lesson plan, students are given a sheet with the molecular formulas of hydrocarbons. As a group, they construct each molecule using...

Students investigate stereoisomers using models that can be rotated and manipulated. For this stereoisomers lesson plan, students try to make models of molecules look alike by rotating the bonds. Using a mirror, the teacher demonstrates...
