Students design an experiment to discriminate between chemical diffusion, osmosis, facilitated diffusion and active transport through a membrane. Be specific about predictions and interpretations!

Students explore oxygen and its physical and chemical propeties.  In this investigative lesson students complete several experiments using oxygen.

Fourth graders paricipate in a demonstration about bond strengths and bond types.

Fourth graders study sickle-cell anemia.

Learners watch a demonstration that introduces them to the idea that friction is a force that impedes motion when two surfaces are in contact. They work in groups to experiment with frictional force using a coffee cup on which they alter...

In this word search activity, students locate words related to biology. The word list includes protists, viruses, plants, spiral, and biotechnology.

Students explore and define methane hydrates and describe ways that it can impact their own lives.  In this methane hydrate lesson students create a molecular model and research methane hydrate. 

Middle schoolers isolate DNA from different food sources. In this biology lesson, students research DNA extraction. They analyze DNA stands collected from the lab, and compare the differences between each.

Students write a hypothesis and complete a lab.  In this investigative lesson students complete their lab and a worksheet about energy. 

Students research carnivorous plants and how they trap insects. They role play as botanists to write a research field guide about a newly discovered imaginary carnivorous plant.

Students discuss how hydrothermal fluid is different from seawater and what happens to it as it passes through the oceanic crust. They observe and manipulate calcuim chloride and baking soda to comprehend how precipates form.

Students engineer new organisms using biotechnology. In small groups, they write procedures, list benefits and drawbacks, and explain how their new organism might affect the environment. After creating their new organisms, they present...

Short slide show provides basic information about drawing Lewis dot structures for covalent compounds. Starts with anatomy of the atom, and then shows the relationship between atomic particles and the Periodic Table of Elements. Offers...

Instructional module focusing on the physical structure of DNA. Discussion incorporates the description of the nucleotides, base pairs, and the double helix shape of a DNA molecule. Site also includes an interactive practice quiz and...

Through this activity, students work with macromolecules, proteins and nucleic acids. The focus is on the atomic structure of proteins, how linear polymers are made, and the surface charges of the resulting polymers. . Multiple-choice...

Investigate the three-dimensional structure of various molecules- both organic and inorganic.

Investigate the three-dimensional structure of various molecules of pigment structures.

Investigate the three-dimensional structure of various molecules of prescription and over-the-counter drugs.

Investigate the three-dimensional structure of different types of organic molecules.

Investigate the three-dimensional structure of different types of material molecules.

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...

Here you will learn how to understand, write, draw, and talk-the-talk of organic molecules. Why were different drawing techniques developed? Organic molecules can get complicated and large. It is a tedious to have to constantly draw out...

[Free Registration/Login may be required to access all resource tools.] Covers structure of water molecule, hydrogen bonding on water, polarity of water molecule, and bond angles of water molecule.

These models show the structures of some basic molecules such as water and carbon dioxide, then move on to show more complex molecular strautures.
