Give young scientists a new appreciation of fresh, clean drinking water. After learning about the ways astronauts recycle their air and water, your class will work in small groups creating and testing their very own water...

Introduce organic chemistry through an analysis of flavor. A three-part unit begins with an overview of the components of flavor. Next, scholars prepare esters through esterification. Finally, they examine how all senses have an impact...

Make a Winogradsky Column to discover how microbes live within the digestive tract. First, participants take a tour of the stomach. Then, gather supplies and start building using a variety of materials. Over eight to 10 weeks,...

In this chemicals worksheet, students review how to read chemical labels, define an acid-base indicator, and decide which way strong acids can be dangerous. This worksheet has 15 short answer and 20 fill in the blank questions.

Eleventh graders use titration methods to study properties of antacids. They look at the strength, effectiveness, PH, and effect of supplements taken at the same time. They make observations after the different mixtures are combined and...

Learners use red and blue litmus paper to determine the category of common substances. They then set up an experiment using vinegar, water, and ammonia (or milk of magnesia) to determine that acids make the best solution for dyeing...

Eighth graders study the concepts of acids, bases, salts and neutralization. They discuss steam adoption program, acid rain and other ecological implications. They use indicators to obtain pH values of household chemicals and to...

Learners describe pH and the importance of it in the natural world.  In this Biology lesson students compare the pH of different mixtures.

Titration, and the lab skills that are needed to support it, is detailed here, with the reasoning behind standard solutions, concentration and volumetric analysis covered. Your young lab assistants will learn the skills of determining...

Ninth graders study the configuration of atoms in molecules to see that it determines the molecule's properties.  In this chemistry lesson students divide into groups and complete their assigned task.

In this ionic equations worksheet, students are given 20 equations to complete. They are to write the net ionic equation and indicate if a precipitate or gas is formed. In addition they are to determine if 11 compounds are acids or bases...

In this solubility equilibria instructional activity, students solve five problems. They calculate concentrations of ions at equilibrium, they determine the effects of adding compounds to a saturated solution and they determine if...

In this DNA instructional activity, 9th graders read a brief excerpt pertaining to the genetic code and identify how proteins know which cell to create. Then they use the genetic code dictionary to draw a diagram showing the codons for...

Students experiment with household solutions and classify them as a base or acid.  In this exploratory lesson students complete a lab where they test products to see if they are an acid or a base. 

Students classify liquids as an acid, base or neutral. They use purple cabbage juice as an indicator to test several liquids in order to group them as acids, bases or neutrals.

Students use a pH indicator to measure the pH of some fruits, common beverages, and borax. Students discover how to differentiate between an object that is an acid or a base.

In this DNA worksheet, high schoolers read information about DNA and messenger RNA. Then students complete 16 short answer questions and color 2 images.

Students discuss the steps of protein synthesis before acting out the process as a class. They are assigned specific roles and receive an instruction card and get materials listed in order to perform their role. Students switch roles...

Students examine how every element is classified based on the physical and chemical properties.  In this properties of metals lesson students divide into groups, complete a lab and finish a data sheet. 

Ninth graders first summarize the process of translation, and then they identify and restate the processes of DNA replication, transcription, and translation in their own words. They also define the purpose of each and identify what the...

Students observe the pH change of an acid mixture poured over soil in a filter. Since the buffering capability of soils differs, you may want to do this experiment with several different soil types.

Young scholars describe DNA and the roles in which engineers are involved with the human body.  In this DNA activity students participate in a class demonstration. 

The question of the structure and function of DNA being the same in almost all organisms is raised here. You will find this PowerPoint a great summary of the building blocks and replication of DNA. The differences between...

You can use these slides to explain the many complicated steps of the Polymerase Chain Reaction. The diagnostic and forensic uses of gel electrophoresis are detailed. This PowerPoint could be used to communicate facts, or to prompt...
