Students add and subtract polynomials. In this algebra lesson, students use algebra tiles to perform operation of polynomials. They model their problems and understand how to combine like terms using tiles.

Students identify the unique pattern DNA forms in each individual, and how that pattern can be used to identify criminals. They have the opportunity to simulate the process of matching DNA samples to those taken at a crime scene.

Fourth graders investigate elements of physical adaptation in insects and organisms. They discover how adaptations can select an insect for survival and make an insect that be used in an outdoor discovery activity.

Students use a rapid method to render the bacterium Escherichia coli "competent" in order to uptake plasmid DNA. They also have growth on the plain LB plates by the untransformed cells (which serve as controls). Students perform a cell...

Students investigate a rapid method to render the bacterium Escherichia coli "competent" to uptake plasmid DNA. They demonstrate the phenotypic changes associated with transformation. They perform a cell resuspension from the...

Students investigate the coefficients in a chemical equation and their relation to moles. In this moles and coefficients lesson plan, students perform a single replacement reaction of copper (II) sulfate and zinc and find the ratio of...

Create trigonometric functions from circles. The first lesson of the module begins by finding coordinates along a circular path created by a Ferris Wheel. As the lessons progress, pupils graph trigonometric functions and relate them to...

Students experience the rotation of the Earth and the Moon, and the revolution of the Moon around the Earth using a playground model.

Students graph and outline the path of a typhoon. In this algebra lesson, students measure the path of the typhoon and create a graph with their data. They analyze the data and make predictions.

Students gather data, make and share predictions about the time of sunrise ans sunset in their area. Patterns are analyzed and shared with students from other areas.

Students conduct an experiment. In this temperate forest lesson, students discuss what kind of animal life can be found in the forest. They read The Magic School Bus Meets the Rot Squad: A Book About Decomposition and complete an...

Young scholars work together to discover the path water follows in plants. They create multicolored flowers. They label each part of the plant and note their function.

Students investigate the flight of paper boomerangs. In this flight lesson, students examine the flight variables of paper boomerangs, which they make, by investigating the concepts of lift and drag. They examine what happens when an...

Students explore the effect that environment has on memory. They analyze their own study habits and draw conclusions about their work behaviors. Baseline capacity is established for the subjects' ability to memorize an increasing series...

Students use the Internet to research the history of Long Island Sound. In groups, they identify the sources of point and nonpoint pollution and how humans are impacting the area. After watching a video, they discuss the role of...

Students discuss force, gravity, and friction as well as examples of each based on what they viewed during a Discovery video. They examine first hand the effect of forces by building their own luge track, making predictions, and testing...

Sixth graders investigate time, distance and speed. For this math lesson, 6th graders convert elapsed time into hours, minutes, and seconds. They analyze a marathon to find data on elapsed time.

Students name the factors (concentration, temperature, and a catalyst) which can affect the rate of a chemical reaction. They use their knowledge of particle theory to explain their observations. Pupils comprehend that the...

Students compare and contrast different versions of "Hansel and Gretel" and "The Gingerbread Boy". Using a software program, they color a gingerbread house design of their choice. Based on the house, they write thier own story making...

Students experiment with currents caused by temperature variations that simulate the origins and flow of polar bottom currents. They discover water density is affected by temperature and salinity, resulting in deep water currents.

Students classify liquids as an acid, base or neutral. They use purple cabbage juice as an indicator to test several liquids in order to group them as acids, bases or neutrals.
