Students determine the best solvent system for separating a methylene blue/sodium fluorescein mixture by thin layer chromatography. They conduct an initial TLC separation using ethanol and a different solvent mixture and analyze the data...

Students investigate hot melt glue using a hot melt glue gun as an an injection molding simulator and a melt index viscometer. They evaluate the effect of heating and cooling by weighing the glue extruded over a constant time period.

Students grow E. coli strain HB101, which contains the plasmid pUCD607 with the bioluminescence (Lux+) gene. The plasmid containing the Lux+ gene is isolated from the E. coli, then characterized by restriction analysis.

Students explore how an oil spill is contained and cleaned up. They investigate an oil absorbing polymer that is hydrophobic, absorbs up to 19 times its own weight in nonpolar liquids, floats on water, and can be reused or disposed of by...

Students investigate issues of degradation and weathering of polymeric materials during their useful life. They evaluate photodegradable plastics and their viability as an environmental solution for litter and investigate the qualitative...

Students compare their perceptions of risk to the perceptions of scientists and risk professionals. in small groups, they evaluate risks on a scale of 1 to 10 for the average American on a yearly basis.

Students investigate the cause of death of a fictitious school janitor. They develop hypotheses based on information discovered by examining the labels of household chemicals.

Integrate geography with literature in this interdisciplinary lesson. Begin by reading a poem such as The Time We Climbed Snake Mountain by Leslie Marmon Silko. On a large map, place push pins in the cities or states mentioned. An...

Engage your learners in global events. The makers of the film Invisible Children began the Kony 2012 Campaign to bring awareness to the Lord's Resistance Army. You can show your class the video Kony 2012 and spark discussion with the...

Students use an on line simulation to produce ammonia using Haber's process. In this Haber's process lesson plan, students use a spreadsheet to manipulate the pressure, temperature and catalysts used in the production of ammonia. Their...

Students investigate child labor during the Great Depression. For this US policy lesson, students evaluate multiple layers of the social, economic, and political affects of policy during the Great Depression. Students will engage in 5...

Design and construct buildings with rooftop gardens. Junior engineers work in groups to build two buildings and then perform experiments to determine whether or not a garden affects the building temperatures. They graph and interpret...

Students analyze the basics of an Excel spreadsheet. They highlight cells in a spreadsheet. They make a column graph. Students are introduced to X-axis and Y-axis. They play various address games on the spreadsheet.

Fifth graders define words. They create a dichotomous key. After carefully examining pill bugs, 5th graders record observations. They compare and contrast habitats of pillbugs.

Experiment with chocolate coating on cookies! What a delightful way to learn about food processing and chemical engineering. Throughout this activity, groups collect measurements and make calculations. They conclude by writing...

Tenth graders investigate dilations and explore the dilation transformation before investigating the properties of a dilation using Cabri Jr. Students extend the concept of dilatation to the coordinate plane.

Get some competition going in your life science class. Give lab groups a variety of plant parts, all of them fruits, except one. Their mission is to make observations, compare and contrast, in order to be the first to identify the...

Create models of the infrared, visible, and ultraviolet portions of the electromagnetic spectrum. Working in small groups, your class can investigate metric conversions calculations. They will find the length of the waves in nanometers,...

Your older elementary students investigate electromagnetic energy and the electromagnetic spectrum. They will observe 7 items represented in the electromagnetic spectrum and make a poster of all the things the items have in common. After...

Andree Walker thought of everything when he wrote this resource. It includes a detailed list of materials and background information links for the teacher. In addition, it has procedures, a macroinvertebrate identification key, and tally...

Groups rotate through a series of stations and work with a partner to observe sound waves. Children describe sound in terms of pitch, volume, and frequency. To apply their new knowledge, the class considers how these observations can...
