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
Heating Crystals
Students examine the effects of heating on various crystals. They formulate and revise scientific explanations and models using logic and evidence. Students work individually during this experiment.
Curated OER
Animal Behavior
Students investigate stimulus-response behavior, learned behavior in animals and innate behavior in animals. In this animal behavior lesson plan, students answer questions about their reactions to a toy cap gun that is fired off in...
Curated OER
Titration Lab
Students determine the concentration of an unknown solution using titration. In this chemistry lesson plan, students explain the difference between acids and bases. They discuss the role of indicators in titration.
Curated OER
Don’t be a Stoic about Stoichiometry
Students review balancing chemical equations. In this chemistry lesson, students calculate moles of an unknown substance based on stoichiometric relationships in the balanced equation. They cite applications of stoichiometry in the real...
Curated OER
Photosynthesis and Respiration
Eighth graders differentiate photosynthesis and respiration. In this biology lesson, 8th graders draw a diagram explaining these two processes. They answer a quiz after the lesson.
Curated OER
Code Makers - Electron Configuration, Aufbau Principle
Learners write the electron configuration of elements using the Aufbau principle. In this chemistry lesson, students build their own key that demonstrates the principle.
Curated OER
I Have the Solution!
Young scholars explain how to make solutions with specific concentration. In this chemistry lesson, students differentiate acids and bases. They calculate molarity of solutions.
Curated OER
A Solution for Moles
Learners calculate the concentration of different solutions. In this chemistry lesson plan, students explain what a solution is. They explain ways to change the concentration of a solution.
Curated OER
Cycles Review
Eighth graders discuss the four major cycles of matter. In this general science lesson, 8th graders decide which of the four is the most important. They share their opinion in class.
Curated OER
Australian Ecology and Bushfires
Eighth graders discuss the different types of ecosystem. In this earth science lesson, 8th graders explain the benefits and harm of fire. They research articles about bush fires or controlled burn instance and share it with the class.
Curated OER
Pellagra Case Study
Students examine a case study documenting the experience of three teens in the 1920's era with a disease (Pellagra) which was prevalent throughout the United States, most particularly in persons with a corn based diet. They create a...
Curated OER
Where My Peeps At?
Students conduct a series of activity that demonstrates Charles' and Boyle's Law. In this chemistry lesson, students determine the relationship among pressure, volume and temperature. They solve problems using mathematical equation.
Curated OER
Acid and Base Testing
Young scholars study descriptions of indicators and the way they are used to identify acids and bases. They use this information to determine if unknown solutions are acids or bases.
