Although biochemistry of the human body is a vital topic, it doesn't have a chapter dedicated to it in many biology textbooks. If that's the case with your text, you can use this resource as a guide for designing your own lecture and as...

The majority of this presentation is a collection of diagrams and graphs that back your lecture on biogeochemical cycles. The last few slides define ecosystems and the Gaia hypothesis. You may find these slides valuable, but will...

A three-page quiz assessing budding biologists' understanding of classification. Middle-level learners may need a little additional time on this, but should be able to handle the concepts with ease.

Have you ever wondered why you aren't taller or invisible? It all comes down to your dominant and recessive genes. Introduce your class members to genetics with a presentation that includes worksheets for young geneticists to...

Framed as an organic chemistry practice test, this resource could be used for a variety of purposes. Composed of 15 questions about organic compounds such as isomers, alkynes, alkenes and amines, and other topics related to organic...

In this electrolytes and solubility learning exercise, students answer questions about electrolytes and write balanced equations for the dissociation of salts in water. They also determine solutes that are soluble in water and write...

Fifth graders investigate evidence for changes in matter that occur during a chemical reaction.

Students see how an infectious disease such as AIDS may be quickly transmitted throughout a population. They conduct a simulated transmission of an infectious disease and mathematically determine the number of possible infected individuals.

Students use indicator paper to determine if substances are acidic, basic, or neutral. They test for Ph levels in them. They investigate the effect of oxygen on darkening fruit cut and exposed to the air. They observe vitamin C as an...

In this organic chemistry worksheet, learners solve 20 problems including isomer structure, functional groups, types of reactions and the polymers that make up the structures of organic molecules.

For this compounds worksheet, students review the rules for naming compounds. Students apply these rules by writing the chemical name or formula for the 50 compounds given.

Young scholars write and balance five chemcial equations which have been observed throughout the process of completing the experiment. They use vacuum filtration to recover suspeneded particals from a colloidal suspension. Students...

Students examine the molecular studies of organisms that have led to a new era in their understanding of speciation and evolutionary relationships. Students study the allelic frequency of genes controlling specific molecules and assess...

Young scholars determine the amount of vitamin C present in 3 samples of juice stored in various light conditions. In this vitamin lesson plan, students investigate the amount of vitamin C present in juice exposed to different quantities...

Students examine solubility and the significance of water.  In this aqueous solution lesson students complete a lab activity on soil profiles.

In this molarity worksheet, students apply the definition of molarity to the given balanced equations. This worksheet has 4 problems to solve.

In this pH worksheet, students experiment with dilutions of acidic solutions to test for the pH using cabbage as an indicator. They then test a variety of substances for pH. On day two of the lab, they test conductivity of solutions and...

Students investigate the best antacids for sour stomachs. In this antacids lesson plan, students use different antacids, balloons and flasks containing 0.1 M HCl. They place the balloon with the antacids in them on top of the flaks and...

Learners analyze data taken from proteomic experiments. In this biology lesson, students explain the importance of bioinformatics tools in the study of proteins. They evaluate scientific results using math and computer software.

Did you know that meat tenderizers contain DNA cutting enzimes? Did you know that you can isolate your own DNA? Or the DNA of fruit? Explore with your learners the DNA world with a series of experiments using readily available materials...

Tenth graders are provided with a piece of paper such as index, art, construction, or computer coating it with a universal indicator. They use cotton swabs HCl and NaOH to draw a picture repeating the same process using lemon juice and...

Students are guided through a process in which three questions are addressed by retrieving beta hemoglobin sequences from online databases, and using online tools to compare those sequences in student-selected animals.

In this environment worksheet, students answer 6 different questions. The questions are really an activity for each one. This requires extra space to complete them on separate worksheets.

Students illustrate the molecular nature of matter and show that chemical change involves alteration of molecules.
