RCX Car Line Graph
Pupils 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.
Curated OER
FOOTSTEPS IN TIME
Learners measure and correlate their foot lengths and body heights, then use this data to estimate height of Laetoli hominids. They use metric measurement and graphing to determine these heights.
Curated OER
Extinction
Students explore reasons why the dinosaurs became extinct, and the specific needs (habitat, environment, food) of individual types of dinosaurs.
Curated OER
Comparison of Snow Cover on Different Continents
Students use the Live Access Server (LAS) to form maps and a numerical text file of snow cover for each continent on a particular date. They analyze the data for each map and corresponding text file to determine an estimate of snow cover...
