Students conduct qualitative and quantitative investigations based on the interaction between water and various polymers. They determine the percent moisture contained in various plastics along with a qualitative procedure to determine...

Students examine water's properties. They participate in hands-on activities to show the properties of water.

Young scientists explore Earth elements by conducting an experiment. They define water vocabulary terms such as condensation and precipitation. In addition, they conduct a water experiment in which they build a terrarium, so they can...

Students investigate the properties of water. In this chemistry of water lesson plan, students observe a demonstration of the properties of water using sand, sugar, oil, vinegar and salad dressing. Students experiment with water, pepper,...

Through three activities, first-time physical scientists wonder at the properties of water. Freeze some soda cans and a container of water prior to the investigation to show that water expands when frozen. Lab groups experiement with...

Blend chemistry with cooking in this exploration of polymers, carbohydrates, and food science. Experimenting with gelatin produces concrete examples of the bonding and ploymerization discussed in the instructional activity. Copious,...

Learners examine distribution of water and minerals. In this surface and groundwater lesson, students conduct an experiment with fresh and salt water making hypothesis and drawing conclusions about minerals. 

High schoolers investigate how to denature proteins. In this denaturing protein lesson plan, students explore the different ways to denature proteins in the lab. They use heat, acids and bases, organic compounds and heavy metals to...

Students experiment with water as a component of suspensions, solutions, and heat conduction contributing to the use of food and the health and wellness of human beings.

Students examine a density demonstration involving ice cubes and beakers of water and alcohol. After observing how one ice cube floats in water and sinks in alcohol, they determine which mixture of the two would suspend the ice cube in...

Students construct models of the way water molecules arrange themselves in three physical states - solid, liquid, and gas. They explain the molecular behavior of ice, water, and water vapor.

Enzymes in our bodies each have a job to do. Learn the factors that affect the activity of some enzymes using the third activity of an informative 12-part biology series. A three-part laboratory activity asks teams to investigate how...

Students study the concepts of polymerization and the function of crosslinkage.  In this polymer lesson students complete a lab activity and write down their observations. 

Students investigate adhesion, cohesion and surface tension. In this molecular forces lesson plan, students observe multiple demonstrations that show surface tension, the attraction of water molecules to each other and the ability of...

Young scholars examine amino acids and discuss the properties of side chains.  In this proteins lesson students demonstrate the foldings of peptides.

Students investigate the affect of soap and water temperature on surface tension.

Pupils observe and record what occurs when yeast is added to hydrogen peroxide. They indicate why a chemical reaction (decompostion) must have occurred during the experiement. Pupils explain why yeast was used. Students comprehend the...

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

Young scholars experiment with crystals and polymers and examine their roles in food science.

Students conduct a simple test to determine how many drops of each of three liquids can be placed on a penny before spilling over. They come up with an explanation for their observations about different amounts of liquids a penny can hold.

Students explore chemical cahnges and the effect of temperature on chemical mixturees, They make observations of the behavior and appearance of certain chemical mixtures and reactions.

Tenth graders explore DNA using online tutorial. They perform their own DNA extraction from a clove of garlic and identify the key components of DNA.

Students examine a PowerPoint production on molecules. Then they construct their own molecule and define what an atom, molecule, and matter is. They make a H2, HCI, and an H2O molecule. Finally, a drawing to accompany the actual model is...
