Students develop a line graph based on distances that an RCX car drives in specified amounts of time. They then are given a specific amount of time for the car to drive and be asked to extrapolate the car's distance from the graph.

For this metric system worksheet, students read about metric and place value relationships, examine some sample problems, and then complete 5 conversion charts.

Students examine how the circumference, diameter, and the relationship of Pi of a circle are related. They count the summer rings of a tree to determine its growth.

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 investigate Mexican holiday celebrations and compare them to American Christmas holidays. They conduct a Mexican Christmas Scavenger Hunt. The lesson uses a streaming video in order to engage students in the main objectives.

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 investigate why some objects float or sink in water. In this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.

Students discover plant chemical processes through three lab activities. Overheads, data sheets, and teaching procedures provided for the unit covering photosynthesis, respiration, and transpiration.

Students explore the concept of estimating and organizing a group of objects into an array to count the exact number of items. They create their own arrays and practice elements of estimation.

Students challenge "common knowledge" against newly learned estimation strategies and put those strategies into use. They consider variables in estimating different groups of objects and practice skills of representing numbers.

Students investigate recycling. In this environmental lesson, students design a recycling program for their school. Students collect data about how much recyclable materials they use in one week. Students also survey classmates about how...

Learners calculate the height and altitude of a pyramid. In this geometry lesson, students define the parts that make up a pyramid. They use the Pythagorean Theorem to find the missing parts of a pyramid.

Students create a simple paper parachute. In this parachute design lesson, students examine the effects of the wind and make napkin parachutes.  

Students discover how engineers use sound energy. They participate in hands-on activities in which they discover how we know sound exists. They identify different pitches and frequencies as well.

Learners participate in activities to learn about Atherosclerosis.  In this investigative lesson students participate in activities that allow them to describe parts of the body, analyze changes in the body and write a story about...

Students are introduced to the concept of surface tension, its dependence on material composition, and how it can produce uniquely shaped surfaces.

Young scholars investigate the properties of air through hands-on activities in conjunction with the demonstrations in a 3-2-1 Contact Video.

Young scholars examine tree-ring dating and discuss the lack of water the settlers in Jamestown faced. They create paper tree rings, simulate rain patterns, and describe the history of construction paper tree sequences.

In this math instructional activity, students find the solutions to the missing angles and sides of the triangles using the correct trigonometric ratios.

In this sample mean activity, students explore different ways "average" is used. Students use this information to find the sample mean of the height of a large class of students. Students find the mean, median, mode and range of two sets...

Sixth graders study friction and drag. In this science lesson, 6th graders use different models of gliders and test to see which of the gliders fly the farthest. Students analyze their data and construct a graph.

Students use the Internet to gather information about dinosaurs. They practice navagating through the different websites. They also practice listening to directions and also explore how to fill out a KWL chart.

Ninth graders explore how electricity is created and distributed through alternative production methods. Students participate in hands-on activities, research, lecture based instruction, and CD ROM resources.

Eighth graders complete worksheets on reading the distance on maps in miles or kilometers. In this maps lesson plan, 8th graders use a calculator and ruler.
