GPS Receiver Basics
Pupils practice using a GPS receiver. They walk in different directions and monitor their progress on maps. They enter specific locations and use information given to them to get them back to their original locations.
Curated OER
State Your Position
Learners practice using a global positioning system. They discuss the use of celestial objects as navigation points and its problems. They list the advantages and disadvantages of GPS as well.
Curated OER
Testing the Hypothesis
Learners create and conduct various experiments to determine the origin of a family artifact, and then determine whether their results were successful. Students summarize their results and evaluate whether their hypotheses were correct.
Curated OER
Sediment Tubes
Students observe how different density soils and rocks behave in wind and in water. They make predictions and careful observations as they explore sediment transport and sediment rates in streams and rivers.
Curated OER
Building Paper Bridges
Students construct a bridge that can hold 100 pennies. In this math lesson, students evaluate the strength of their bridges. They predict how much weight a bridge can hold based on its design.
