Using blue prints, 4th grade students build a car and then perform experiments recording data as they clock the run time of their vehicles. Students use K'Nex to build their car. In the experiment a "pulley" is attached to the front axle of the car. Weights (washers) are added to the other end of the pulley which hangs off the end of a table. Gravity then propels the car into motion. Variables include adding more weight to the end of the pulley and also different loads (wooden blocks) to their vehicles. Run time is clocked with a stop watch. The data is recorded and graphed.

Many parent volunteers helped the students in Mrs. Kiker's class with this science experiment.
Animal Growth & Adaptations
As a part of the Animal Growth and Adaptations Science Kit, students have the opportunity to "dissect" an owl pellet. An owl pellet is the regurgitated indigestible parts of an owl's meal. Since owls eat their food whole, this provides a wonderful opportunity for students to see what an owl eats and how it relates to their environment.

Using toothpicks, students pick apart the pellet separating hair and feathers from bone. The pellets our students examined were from small rodents. Students use a Bone ID Sheet to help them determine which animal(s) the owl ate.
