In this isomer worksheet, students use molecular model kits to build isomers. Students work in groups and draw and name the isomers they build. They answer 9 questions about both geometric and structural isomers.

Students create models of structural isomers, geometric isomers, and polymers.  In this chemistry lesson, students are given definitions and molecular model kits to create a variety of different isomers and polymers.

Learners explore the concepts of energy transformation and conversion. They engage in Internet and hands-on activities. Students visit the Atoms Family Website and complete a Building a Better Pyramid activity by adding insulation to...

Learners conduct a series of activities to explore the nature of cells. In this biology lesson, students observe plant and animal cells under the microscope and compare them. They differentiate osmosis and diffusion.

Science teams make models of four different hydrocarbon compounds that we commonly use for fuel. Then they demonstrate chemical reactions that result when energy is produced. This can be used as an enrichment when your class is studying...

Students examine the importance of proteins including their function and structure.  In this protein lesson plan students play a game to help them better understand proteins.

Students examine a microscope from the 18th century. In this microscope lesson, students investigate how it works, what it was used for and how the tool has evolved through the years. Students also build knowledge on how compound...

Young scholars conduct several simple lab activities to explore the five fundamental load types that can act on structures: tension, compression, shear, bending, and torsion. In this activity, students play the role of molecules in a...

Learners in pairs, select and view proteins from the Protein Data Bank. After downloading the tutorial and instructions, they identify the protein's structures and primary biological functions. Then, students present their findings to...

Students study the basic structure of the atom. In this chemistry lesson, students explain how colors relate to energy that electrons emit. They calculate energy of the emitted photons.

Molecules to the Max! refers to a movie released in 2009 about the world of atoms and molecules. A helpful discovery guide provides five posters on science topics typically covered at the middle school level. It also explains the...

Students engage in lesson concerned with the concept of the ozone layer. They write a reflective journal using prior knowledge. Students read sources of information about the existence of a hole in the ozone layer. Finally they create...

Students analyze the amount of space required to pack round objects. For this geometry lesson, students practice using space economically by practicing packing spheres into beakers. They then translate this concept to molecules being...

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...

Learners construct cladograms (evolutionary trees), showing how shared derived characters can be used to reveal degrees of relationship. They interpret and analyze cladograms, and determine where unclassified vertebrates would fit on a...

Tenth graders work with a partner, and copies of the attached worksheet "Amino Acid Codon Table" They discuss ways an organism, obtains and uses proteins. Students view a teacher prepared DNA strand banner, and record the complementary...

Tenth graders work in teams to order events of DNA transcription and translation protein synthesis. In the second lesson, they put the steps of mitosis and meiosis in order using a concept map poster. They use modeling clay to create...

In this interactive activity from NOVA, learn about the molecular structure of steroids. See the intermediate molecules that are part of the pathway for synthesizing cortisone from diosgenin.

Build a molecule in 3-D. Add single, double, and triple bonds, or a lone pair of electrons to an atom, learn what the molecule's geometric name is, see the bond angles, and manipulate each molecule to view it from all sides. Then study a...

Explore molecule shapes by building molecules in 3D. How does molecule shape change with different numbers of bonds and electron pairs? Find out by adding single, double or triple bonds and lone pairs to the central atom. Then, compare...

Explore molecule shapes by building molecules in 3D. Find out how a molecule's shape changes as you add atoms to a molecule.

This lesson covers chiral molecules, which are important in carbohydrate and protein chemistry. Understanding the difference in their structures helps with understanding the different biochemical properties of molecules with similar...
