Young scholars discover dangers to human health by researching what's in our drinking water. In this water purification instructional activity, students discuss the conditions of water in undeveloped countries and why it is unsafe to...
Curated OER
Glucose Factory
Fourth graders determine, through laboratory activity, the presence or absence of glucose in a variety of plant leaves and stems. They work in groups and perform a three part laboratory which shows them how plants convert sunlighht to food.
Curated OER
Volcanoes:How Safe Are They?
Young scholars explore volcanoes, locate them on maps, record general information about volcanoes, and organize information on a fact sheet.
Curated OER
Enzymatic Browning Experiment
Students, in groups, experiment with Heat Blanching, Vitamin C Dip, and Sulfur Dioxide Dip to see if they can prevent enzymatic browning.
Curated OER
The Flame and the Atom:
Students investigate the structure of atoms. Students read information about the Rutherford model, the Bohr model, and the Quantum Mechanical model examining each for its scientific validity. They watch a PowerPoint presentation of alpha...
