Students estimate the area of boxes using centimeter cubes. They find the actual area and compare it to the estimates.

In this imperial units worksheet, students read the definitions to the following list of imperial units: mile, pint, gallon, foot, inch and pound.

Young scholars apply measurement techniques to create a flying object. They measure, draw, and cut out a flying wheel out of a six inch card.

Students use graphs to calibrate an RCX car. They must then program the car to traverse a maze using their calibrations

Students read the novel Stone Fox by John Reynold Gardiner. Using Lego RCX units, students build and program sleds to re-enact the "home stretch" of the National Dog Sled Race.

Students explore the aspects of a frog's anatomy that allow it to be such a good jumper and jump and record the length of each jump to determine which style of jumping allows them to jump the farthest.

Students explore the concept of perimeter. In this perimeter lesson plan, students discuss how to find perimeter of various shapes. Students use the Perimeter Explorer applet to find the perimeter of various shapes.

Students design different shaped plots and determine the perimeter, area and shape of each. They compare the shapes that have the same area but may have different perimeters.

In this unit, 3rd graders investigate one variable to see if they can make a paper plane fly farther. They use scatter plots to establish a possible relationship between variables then use what they have found to make a paper plane to...

Students recycle discarded automobile tires and create gardening sites for limited space areas.

Third graders create a box big enough to hold a million dollars. This is a project fun to do near the winter holidays with inexpensive gifts included in the boxes. This hands-on lesson very effectively demonstrates the concept of volume.

Third graders estimate the volume and mass of one marshmallow using appropriate standard units. They design and carry out an investigation to find the average of volume/mass of one marshmallow.

Students read and relate the poem, "Clouds" by Aileen Fisher to a demonstration on cloud formation. They create clouds in jars using ice water and matches then discuss the ways clouds can be used to predict weather.

Young scholars research the size of whales using print books or the internet. Students do the research in  groups. They compare and graph the results.

Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...

Learners use seconds, minutes, and hours. They then discuss the size of a thousand. After that they read time in digital or analogue form.

Third graders complete an experiment to introduce them to the concept of water pressure. In this water pressure lesson plan, 3rd graders create pressure in a water bottle and observe the force of water that is created.

Students listen to the book, "Oobleck," by Dr. Suess before experimenting with mystery powders. They determine the proper ratio of powder to liquid to make the Oobleck.

Students use a ball to push and pull to demonstrate the concept of force. In this force lesson plan, students talk about the importance of force in space and use balls to demonstrate this phenomena.

Students investigate how friction affects the movement of a block across surface areas. They test five different kinds of surfaces—smooth surface, wax paper, a paper towel, course, and fine sandpaper. They predict and record the results...

Learners choose a number from one to twelve and tell a number story about it. They listen to the teacher read "Numbers in Art" by Lucy Micklethwait. Students choose three numbers from one to twelve and view works of art while looking for...

Third graders demonstrate how to read and analyze food labels. In this nutrition lesson, 3rd graders watch a food label video and investigate labels from various canned foods. Students create a chart showing the percentage of vitamins...

Learners identify the different steps in the scientific method. In this inquiry lesson, students determine the mass of the gum after chewing it for sometime. They explain what happens to the lost mass.

Students describe the characteristics and behaviors of bats. After viewing a video, they explain how bats use echolocation to navigate and how they find their young within a group. They list four misconceptions about the animal and...
