Curated OER
Chemistry
In this chemistry worksheet, students describe an atom, its parts, the charges of these parts, and atoms life functions. Then they explain what the octet rule states for the placements of electrons around the nucleus of an atom. Students...
Curated OER
Your Digestive System
In this digestive system worksheet, 9th graders identify and explain any difference found in color of the mixtures in two glasses. Then they determine what enzyme was produced by glands in the mouth changing the starch in a chewed cracker.
Curated OER
Temperature and Enzymes
Students compare the times it takes the milk in each of two cups to curdle. They are told that an enzyme that is added to the milk, rennin, is involved in the natural curdling process of milk. Students are asked to consider what...
Curated OER
Catalase Enzyme
Pupils design and conduct an experiment to test their ideas about how to speed up or slow down the rate of an enzyme-catalyzed reaction. They have access to an array of physical and chemical factors that might influence enzyme activity....
Curated OER
Are Enzymes Specific for Their Substrates?
Students discover enzyme to substrate specificity. The experiment uses samples of glucose and lactose in combination with the enzyme lactase. Students observe the reaction between the lactose and the lactase; the lack of a reaction...
Curated OER
An Enzyme- Substrate Model
Students explore reaction rates of an enzyme-mediated reaction. They examine the effects of environmental variables on enzyme function. Students collect, graph, and analyze data relating to the reaction.
