You Are What You Eat: Testing for Organic Compounds in Foods
We have all heard that we are what you eat, but what are we eating? An informative lesson opens with a discussion of the foods pupils have recently eaten. Then, young scientists perform four experiments on seven different foods to...
Curated OER
Sugar and Light
Students connect starch to sugar as the storage form of energy. They find that no starch is produced in the plant without light. Students perform the old favorite of looking at starch deposition in geranium leaves using Lugol's iodine...
Curated OER
Circle Surprise
Students create a large circle out of construction paper and use a hole punch to make many holes. In this art lesson, students brush liquid starch over the holes putting different colored tissue paper over the starch.

Concept Map - Organic Compounds
In this organic compounds, students complete a graphic organizer by placing 36 vocabulary words into their correct places in the concept map.
Curated OER
SEPARATION OF A STARCH-GLUCOSE MIXTURE USING GEL FILTRATION
High schoolers 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
Digestion Experiment and Teacher Made Test
Students complete a digestion experiment using sugar, iodine, corn starch, and sugar test paper to test for starch and sugar in the body. In this digestion lesson plan, students learn how the body breaks down different ingredients.
