Seventh graders calculate the area of certain cages at the Miami Metrozoo after observing a teacher demonstration.

Students simulate an archeological excavation to explain how archeologists identify, date, and make inferences about their findings. They explain the importance of spatial and stratigraphic contexts in archaeology.

Students create three-dimension models demonstrating exponents, multiplying and dividing of fractions, and the use of repeating patterns in tessellations, mirror images, and tiling.

Students create different shapes by putting light on different objects. They change the distance from the object, the light source and angles to make the shadows different. They are to describe the relationship between the light, object...

Students evalute evolutionary theories and processe of Geology. They examine evidence that the movement of continents has had signicicant global impact, major geological events. Students evaluate the forces which shape the lithosphere...

Third graders read a thermometer with accuracy, record observations and data, and infer conceptual meaning. They integrate mathematical charting and graphing skills to organize their data. They explore what happens when they touch or use...

Third graders keep a journal and record the growth of their plant everyday over a two week period. With an observation written down for everyday of the week, they draw a picture of their plant in their journal on Monday and Friday...

Learners identify and describe various organisms living in a pond water environment. They describe the characteristics of living things. Students compare and contrast organisms created by asexual reproduction and sexual reproduction....

In this fraction worksheet, students use twizzlers to demonstrate various equivalent fractions. Students complete ten greater than, equal to, and less than questions.

Middle schoolers determine density and hardness of wood samples based on several investigations. In this physical science and music lesson plan, students visit four centers and perform tests on wood samples to determine densities and...

Emergine space engineers discover the area of complex geometric shapes. They find that, just as a spacecraft is composed of many smaller parts, so can polygons be broken into smaller shapes.

Third graders identify what plants need to grow. In this agricultural lesson, 3rd graders read the book The Empty Pot and discuss the steps to take when planting a seed. Students plant a seed and water it each day. Students discuss their...

High schoolers examine why diffusion and osmosis happen in an egg cell.  In this diffusion lesson students demonstrate a semi permeable membrane.

Fifth graders use tan to solve problems involving right-angled triangles. They solve equations of the form tan(8) =a, for a between 180 degrees and 360 degrees. They state the value of tan (8) in special cases.

Students study fractions. In this equivalent fractions lesson, students utilize fraction strips to enhance their understanding of equivalent fractions. They watch a demonstration and then work independently with their own set of fraction...

Students solve problems using dimensional analysis. In this chemistry lesson, students choose a problem and present it in class. The rest of the class will evaluate the solved problem on the board.

Students observe that colored markers are a mixture of many different colors by performing a chromatography experiment. They make observations, record information, and make generalized inferences from their observations.

Students compare the price and quality of different kinds of plastic kitchen wraps and then rank them from best to worst. They take into account how well it comes out of the roll, if it seals well, it is tangles, how much weight it...

Students examine the properties of a liquid that contains water and food coloring and a liquid that contains water, food coloring and a liquid detergent. They interpret their data, describe properties, and make reasonable explanations...

Students observe a balloon rocket and how it relates to Newton's Third Law of Motion. In this balloon rocket lesson plan, students make a balloon rocket out of balloons, clothespins, straw, fishing line, and duct tape.

Students experiment with a converging lens. They observe the image of an object through a lens. They determine the magnification of the lens.

Students relate the ratio of Pi to the diameter of a circle. In this geometry lesson, students investigate the relationship of the chord of the circle the the number Pi. They define ration, chord, circumference and diameter and find...

Fourth graders rank balls by size from smallest to largest and from lightest to heaviest and then by how much they made the water rise. They then discuss why certain balls make the water rise higher than do other balls.

Twelfth graders build a model of the following figures with the base from column I and the cross-section from column II. Draw the base with labeled axes on the graph paper and construct the figure on top of the base with the play dough...
