Students define density and explain how to determine the density of an object. Students participate in a demonstration that shows the differences in the densities of different liquids and how they affect the liquid's physical properties.

Students observe and record the corrosive nature of oxidation-reduction reactions, and determine the electro-chemical series of selected metals.

Students construct a volcano using baking soda and vinegar. In this earth science lesson, students explain the reaction that takes place when these two chemicals combine together.

Students articulate the difference between the terms heat and temperature. They calculate the amount of energy associated with a given temperature rise and design an experiment to measure the energy of a fuel.

Students study the difference between types of ionizing radiation and how elements are transmuted. They determine that radiation is normal and surrounds us. They calculate the amounts of alpha, beta and gamma radiation emitted from a...

Students create a pond habitat inside and outside their classroom. In this pond lesson plan, students create a habitat with animals, water, and plants in order to create a proper pond habitat.

Young scholars collect specimen and analyze it. In this biology lesson, students analyze and evaluate the diversity found in specific environment. They use the correct terminology as they do their write up for the experiment.

Students examine color perception and how it relates to metamerism.  In this color lesson students complete a lab activity that shows them the three basic components of color perception. 

Learners investigate the effects of acid and bases on dyes made with plant materials.  In this chromatography lesson plan students predict color outcomes and complete a lab activity on color combinations.

Learners explore the different phases of a crystal.  For this mineral lesson students grow their own sugar crystals using a sugar recipe. 

Students compare various brands of floor polishes and test their durability and appearance.  In this floor polish lesson students test different polishes and check performance. 

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.

Students examine water and what causes it to become hard.  In this water instructional activity students use the soap test and determine the mineral content and hardness of a sample of water.

Students examine the different propereties of ice, such as freezing temperature.  In this scientific lesson students complete several activities using ice, like making ice cream.

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 explore what chemical indicators are and use pH paper to determine if something is alkaline or basic.  In this pH lesson students manufacture their own soap.

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

Students research on the history of adhesives. In this science lesson, students select one test to use in finding the stickiness of adhesives. They collect data and formulate a conclusion.

Students examine how and when rust and corrosion occur.  For this corrosion lesson students complete an experiment to see why metals rust. 

Students investigate the concept of an insect. They conduct research about six different insects and identify the different body parts. Students look at the life cycle of the developing monarch butterfly. They also use the library to...
