Curated OER
Mixtures
Sixth graders experiment with mixtures. In this chemistry lesson, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.
Curated OER
Celebrate The Four Seasons
Students investigate cause and effect and compare and contrast how recurring cycles are evident in multiple aspects of their education. They answer questions in the chosen field. Students model each aspect by interpreting, perceiving and...
Curated OER
Scientist Simulation
Students imagine themselves working as research scientists completing the end-steps of a molecular research project and interpreting the data. They compare the gene sequences of normal and abnormal mice and evaluate the protein product...
Curated OER
SEPARATION OF A STARCH-GLUCOSE MIXTURE USING GEL FILTRATION
Students make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other...
Curated OER
Separating a Starch-Glucose Mixture Using Gel Filtration
Students experiment using the basic principles of gel filtration. They use the gel filtration technique for testing for the presence of specific substances. Students discover that starch is a larger molecule than glucose.
