Curated OER
TE Activity: A Roundabout Way to Mars
Students investigate Hohmann orbit transfers using cardboard and string while focusing on the orbits of Earth and Mars. They look at the planets orbits around the sun and transfer orbit form one planet to another to determine what a...
Curated OER
Weathering and Erosion Splashdown
Fourth graders investigate how plants and their roots help slow the erosion process.
Curated OER
Simple Harmonic Motion
Students explain the theory of simple harmonic motion (SHM) by performing hands-on, practical application experiments.
Curated OER
Magnet Trackstar
Young scholars explore websites created by other young people on the topic of magnets. These sites are in the form of a TrackStar and are accompanied by a worksheet to guide them in their information gathering.
Curated OER
Vectors
Students describe motion by the use of adding vectors. They identify the difference between the x and y components of vector quantities. Students are given the Paper Bridge Building handout and the instructions as to where to perform...
Curated OER
Avalanche
Students investigate the concept of avalanches and how they effect people who use the slopes. They conduct research using multiple resources that includes the internet in order to create a final oral presentation.
Curated OER
Pendulum Motion Experiments
Students experiment with simple pendulums to determine the validity of an equation for all angles. Students discover the usefulnes and limitations of approximations in science. Using spreadhseets and a java applet, students observe the...
Curated OER
Satellites
Eighth graders explore the history of space travel and satellites. Through a teacher demonstration, 8th graders observe how a satellite revolves another object. They identify natural and artificial satellites, explore how satellites...
Curated OER
Animating Motion
Students apply what they recall about objects in motion by animati ng sequences of pictures that model a set of physical conditions. They animate the orbital motions of the Earth, the space shuttle, and the Moon based on calculations of...
