Students conduct a variety of experiments to explore gel electrophoresis. In this biology lesson, explain how this process separate DNA and RNA. They discuss the practical applications of this method.

Students conduct various experiments on glucose. In this biology lesson, students differentiate the process of diffusion and osmosis. They test different foods for the presence of glucose and starch.

Students explore how PCR works through various activities. For this biology lesson, students explain how PCR generate copies of DNA. They simulate the process using an online interactive website.

Students explore tobacco smoking and the impact it has on society.  In this health instructional activity students complete several experiments on smoking and lung cancer.

Students build their own kite following certain procedures. In this physics lesson, students explain the aerodynamics concepts involved in flying kites. They trace the development of aviation.

Students examine what a sunspot is and how it is produced.  In this sun lesson students locate and measure sunspots then view them through a camera.

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

Students investigate which diaper is the most absorbent. In this chemistry lesson, students calculate how much water is absorbed by diapers. They identify an unknown powder based on physical and chemical properties.

Students conduct an experiment to observe oxidation. For this chemistry lesson, students explain how rusting happens. They rank metals according to their conductivity.

Students conduct a series of experiments on water electrolysis. In this chemistry lesson, students explain what happens to the molecules during the process. They cite real world applications of electrolysis.

Students identify the characteristics and composition of emulsions. In this chemistry lesson, students classify household products according to emulsion type. They explain how to make the best emulsion.

Students conduct a series of experiments to explore Graham's law. In this chemistry lesson plan, students differentiate effusion and diffusion. They perform calculations using Boyle's, Henry's, Charles' and Graham's Laws.

Middle schoolers investigate the hardness of different water samples using the conductivity meter. In this chemistry lesson, students build their own meter following specific procedures. They identify an unknown sample of water.

Young scholars 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 study the characteristics of yeasts. In this biology lesson plan, students conduct experiments to measure yeast respiration. They discuss the favorable conditions needed for growing them.

Students examine the different propereties of ice, such as freezing temperature.  In this scientific instructional activity 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 activity students manufacture their own soap.

High schoolers identify auxins from their structural formulas. They understand the process of refluxing in chemical synthesis. Students perform thin layer chromatography using silica gel plates to differentiate chemical substances.

Students design and build a foam core house which has a light in each room. They demonstrate an understanding of series, parallel, and complex circuits. They complete a worksheet, in complete, sentences expressing these electrical concepts.

Students explore the use of different textures in watercolor paintings in this late-elementary lesson. Emphasis is placed upon the art element of texture using the science of chemical reaction. The lesson includes one possible extension.

Students learn along with Ms. Frizzle's class. In this Magic School Bus lesson plan, students observe ants doing some tasks by making them a temporary indoor home.

Students investigate the factors affecting projectile trajectory. In this physics lesson, students calculate the range, time and speed of projectiles using mathematical equations.

Learners study practical data analysis within the constraints of the scientific method.  In this data lesson students collect and enter data into a computer spreadsheet then create graphs.
