Metric Mania
Students practice converting units of measurement using the ladder method. In this metric conversion lesson plan students practice converting metric measurements and filling out the worksheet.
Curated OER
Can or Bottle Crusher (Demonstration)
Learners witness the gas law from a demonstration in which a can collapses after the steam escapes. The steam pushes out most of the air from inside the can and then the air outside presses against the can crushing it.
Curated OER
Fertilizer Frenzy
Young scholars design and conduct an experiment testing the effect of fertilizers/soaps on algal growth. They estimate and predict, identify the variables, formulate a hypothesis, and record and analyze the data, presenting their...
Curated OER
Water Cycle Column
Students use common materials to construct a working model of the water cycle. They then observe and explain evaporation, condensation, precipitation and percolation as aspects of a continuing cycle. Students also complete worksheets and...
