In this isomer worksheet, students learn about the structures of isomers and then they draw the isomers for six organic compounds.

In this atom worksheet, students read about the structure of the atom including its subatomic particles and John Dalton's theory of the atom. Students also read about the differences between atoms, molecules and compounds. They answer 30...

Students explain the concepts of what DNA is and where it is located in a cell, identify the two types of molecules that make up the rungs of a DNA molecule and identify the two types of Purine and Pyrimidine molecules

What's in a cell, anyway? Kids read informational text on what makes up both animal and plant cells, including a page of vocabulary terms they will need to be familiar with (cytoplasm, ribosomes, vacuoles, etc.). Full-color images...

Who knew that a possible answer to Earth's energy resource problems was lurking deep beneath the ocean's surface? Part four of a six-part series introduces Earth Science pupils to methane hydrate, a waste product of methanogens. After...

Students read the Who We Are Section on Calfee Designs Webpage and discuss carbon usage. They work in pairs to look up the minerals diamond and graphite then create a chart on the properties of each mineral then compare how they differ...

After drawing the valence electron distribution of 13 basic elements, there are spaces to draw 18 more complicated molecules.  For each molecule, there is space for a Dot structure and Lewis structure that best describes the...

Name is Bond, covalent bond. Through readings and answering questions, classes explore the different types of chemical bonds, their characteristics, valence shell electron pair repulsion theory, and atomic orbitals. 

Here is an interactive presentation on molecular geometry if you have materials for building molecule models along the way. Isomerism is introduced by means of a graphic organizer. Viewers then imitate two molecule models and learn that...

During this hands-on activity, young chemists build molecular models based on the Lewis dot structure before studying valence shell electron pair repulsion theory. 

Ninth graders examine the structure and function of biomolecules. In this food molecule instructional activity, 9th graders will examine various  types of biomolecules such as  carbohydrates, lipids, proteins, and nucleic...

What's smaller than a kiwi seed? Atoms! Basic atomic structure is detailed for beginning chemists in a light-hearted animation. Protons and neutrons are explained as part of the nucleus, and so are electrons that encircle the nucleus....

In this solutions worksheet, students answer questions about the solubility of various substances in solvents such as oil in water and nitrogen gas in helium. They draw water molecules to show bonding between them and they diagram a...

How do changes in DNA affect an organism? Scholars explore chromosomes, genes, DNA, and mutations by modeling the DNA of a strawberry. They build a DNA model, then manipulate it to show how changing the genes transforms the strawberry...

Atomic theory, experiments that contributed to our knowledge of matter, atomic structure, isotopes, and ions are covered in these 33 slides. Quality diagrams and labeled charts will help activate understanding. The presentation concludes...

Ninth graders conduct research on the subject of sea water. They use a variety of resources to obtain information. There are helpful resource links listed in the lesson. In conjunction with the research students make inquiry of the...

Young scientists demonstrate their understanding of cell transport on this comprehensive worksheet. Focusing on cellular structure and the different processes that allow materials to move into, out of, and throughout animal...

Tenth graders identify the parts and functions of the cell. In this series of science lessons, 10th graders investigate crystal formation in covalent compounds. They investigate the factors affecting reaction rates.

Here is a PowerPoint that displays multiple organic compound structures and asks viewers to identify the formulas, isomers, or potential products after a given addition reaction. This is a comprehensive set of slides that reviews...

For this chemistry, learners draw the Lewis structures of 20 covalent compounds. They demonstrate how the lone pairs are distributed in the molecule.

Young scholars view videos and worksheets and construct a model of a water molecule. In this atomic structure lesson plan, students view video clips and handouts about matter and nanoscience. They construct a model of a water molecule...

In this biology worksheet, students complete 20 fill in the blank questions about eukaryotic cells. They identify the parts and functions of cell organelles.

Students explore the properties of enzymes. In this chemical reaction instructional activity, students explore enzymes through a Web-quest and investigative study. Students will collect and summarize data and create a class presentation....

Eighth graders investigate the effect of temperature on the volume of a gas in a closed container. They measure the height of the water in their beaker/container, conduct their experiment, and create a graph to illustrate their data.
