Students participate in an investigation in which they compare a polyethylene bag designed for recycling or disposal with a polyethylene food storage bag. Students use hexane to determine the differences between the low density...

Students examine the variety of food preservation methods available today. In groups, they participate in an experiment to determine the conditions that encourage or stop the growth of bacteria. To end the lessons, they discuss the...

Eighth graders investigate chemical reactions to produce polymers. In this polymers lesson plan, 8th graders experiment with sodium silicate and ethyl alcohol to make a polymer. They also experiment with borax and glue to make a polymer....

Students measure and record the mass of the nut to be tested to the nearest 0.01 gram.

Students investigate the effects of substances on the viscosity of egg yolks. In this viscosity lesson plan, students separate egg yolks from their albumen and then add different masses of albumen back to each egg yolk. They measure the...

Young scholars investigate ways to improve their bone strength. In this bone strength instructional activity, students explore the link between exercise and bone growth. Young scholars study the effects of proper nutrition and exercise.

Students determine the number of calories in various products, and the amount of energy created when objects burn.

Students investigate how small amounts of minerals or metals are mined out of very large masses of rock using birdseed. They study the economics of valuable commodities. They look at environmentally conscious mining and how reclamation...

Students examine the importance of good quality safety gear. In this investigative lesson, students will tests various polymers, collect data, and analyze the data to determine which polymer is best for safety helmets. They will design a...

Students collect and categorize solid waste produced in the classroom. They weigh the waste that has been collected over one week's time, and separate it into recyclable and non-recyclable waste. They talk about the role of engineers in...

Students experiment observing a demonstration on models of density-driven currents which are typically found in an estuarine system of water flow. They compare/contrast water temperature and salinity to the formations of estuarine currents.

Middle schoolers study Norman Borlaug. In this reading and math lesson, students research Norman Borlaug's work and write a narrative interview with Borlaug. Middle schoolers complete a variety of activities using wheat stalks.

Fourth graders, in pairs, explore energy transfer and species interrelationships by viewing slides on a microscope. hey explore phytoplankton (producers) and zooplankton (consumers)

Students conduct an experiment to observe the properties of both salt and freshwater. They explain why freshwater will stay at the surface while salt water will travel up a river bottom because of density. Students also research the...

Students explore the meaning of mining. In this Science/Math lesson, students engage in a small group activity to sort and calculate the value of seeds/beads.  Additionally, they are made aware of environmental damages which will...

Students investigate how the six natural regions of Arkansas work together to form the economic system of the state. They read a paragraph and articles about the state and complete an activity that demonstrates interdependence. They...

Students explore an estuarine system to gather data on density driven currents. This type of current is contrasted with temperature and wind driven currents.
