Curated OER
Measuring Water Quality
Learners are introduced to the various methods of measuring water quality. In groups, they test various water samples using the different methods, writing them down for pH, oxygen, salinity, and nitrate levels. They use their data to...
Curated OER
Investigating the Uses of Backyard Bacteria
Students discover that the answers to some of society's waste and clean-up problems may be no further than the soil beneath their feet. They perform a Gram stain on the colonies to determine some of their characteristics.

Plant Biotechnology: Controlling Tissue Differentiation
Students demonstrate hormonal control of plant tissue differentiation and relate this differentiation to gene expression. They explore the effects of hormones (auxin and cytokinin) on the genes that control tissue differentiation in callus.
Curated OER
Plant Biotechnology: Controlling Tissue Differentation
Learners demonstrate skills of biotechnology stringent aseptic technique and statistical analysis. They describe hormonal control of plant tissue differentiation and relate this to gene expression. Students observe the effects of...
Curated OER
The Story of the Transistor
Students brainstorm on how certain items have become smaller as technology advances. They watch a video about the history of the transistor.
Curated OER
SOME BASIC LESSON PRESENTATION ELEMENTS
Students review the Madeline Hunter Direct Instruction Model. They incorporate objectives, standards, anticipatory set and modeling. Students use guided practice/monitoring and closure daily.
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...

Separating a Starch-Glucose Mixture Using Gel Filtration
Young scholars 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.
