Students examine different types of DNA fragments. They record and analyze their results. They determine who is the criminal in the story.

Students simulate the Sanger method of DNA sequencing using color pop-beads as a representation of nucleotides and dideoxynucleotides. Students assemble DNA sequences and run their sequences through a "sequencing gel" and sketch what...

High schoolers compare different DNA and run a gel electrophoresis.  In this DNA lesson students complete a DNA activity that allows them to better understand its structure and function. 

Students investigate the effects of an acid and a base on the structure of milk protein. They observe the changes to droplets of milk when adding ammonia and lemon juice and relate the changes to old, curdled milk. An extension using...

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

Students examine the genetic relationships of different organisms. In groups, they discover the importance of genes and how different amino acids show various evolutionary relationships. They use an online database to continue their...

Students investigate the physical structure of a protein by using a computer simulation tool. They record its primary amino acid structure while viewing it in three dimensions for a better visual recognition. There is also a comparison...

Young scholars balance chemical equations and solve for gram to mole ratios.

Students are taught how to format and enter data into an Excel spreadsheet. They make a graph and interpret graphed data. Students discuss possible impacts of water chestnut invasion. They graph data on water chestnut. Students report...

In this dietary fibers worksheet, learners compare and contrast the properties of different fibers: cellulose, hemicellulose, pectin, guar, agar, and xanthan gum. This worksheet has 5 short answer questions.

Learners witness various stages of mitosis through preparing onion root tip slides. With teacher guidance, they learn a great deal through the hands-on process of preparing the slides themselves.

Students pretend they are each genetic engineers with a test tube of unknown DNA (PCR'd) possibly taken from blood cells of someone with a genetic condition.

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....

What happens when genes change? Junior genetic investigators examine the effects of mutation in the third unit of a four-part Biotechnology series. Individuals discover the types of mutations through a series of PowerPoints, then partner...

Students identify various kinds of paints by using the scientific method.  In this solvents lesson students collect data and identify paint samples while working in teams.

In this chemical reactions worksheet, students answer 20 multiple choice questions about chemical equations, chemical formulas, oxidation and reduction reactions and acids, bases and salts.

Students test different water solutions for the presence of ions. In this water testing lesson plan, students test for iron, calcium, chloride and sulfate ions in solutions. They indicate positive tests based on their results and they...

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

In this chemistry worksheet, students identify the process of Stoichiometry and use it to calculate various chemical reactions similar to that of a recipe. In addition, they identify a connection between isoamyl alcohol and the product...

Students discover the law of conservation of mass though experimentation.  In this chemistry lesson, students experiment with acid - base indicators to determine the presence of carbon dioxide. Students complete the labs with...

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.

Learners study using analogies between common items or occurrences and science concepts. They use the analogy of cookie recipes to that of the DNA "recipes" for living things to help us explain more about mutations.

Students conduct an investigation of differentiating between different types of DNA. This is done with a simulation activity of being a scientist in charge of selling different sets of DNA for research which requires different...

Practice naming chemical compounds or stating the formula when given the name. Discover how well you have mastered these skills either by time or percentage correct.
