Introduction to the Scientific Method
Students designs and conduct a scientific experiment that identifies the problem, distinguishes manipulated, responding and controlled variables, collects, analyzes and communicates data, and makes valid inferences and conclusions.
Curated OER
Simple Machines
Students discover what simple machines are and identify a gear, a pulley, and a lever. In teams, they build at least two models each of simple machines and challenge them with specific instruction cards. Finally, students present and...
Curated OER
Ice Cold
Students design and conduct an experiment to investigate what happens when salt and ice come together and to determine if one form of salt is better for melting ice on steps and sidewalks.
Curated OER
Endothermic or Exothermic That Is the Question
Students conduct an experiment to determine what happens to heat energy during a chemical reaction. They examine an endothermic reaction by observing a chemical reactions.
Curated OER
Physical/Chemical Properties of a Burning Candle
Students investigate the physical and chemical properties of a candle before and after it is lit. They conduct a burning candle experiment, and complete a KWL chart and worksheet, recording the results of the investigation.
