Mystery of the Eleven Unknown Substances
Fourth graders identify eleven white substances that are commonly found in the household. They, in pairs, perform experiments on a variety of substances, and must identify them based on the reactions they observe.
Curated OER
Physical vs. Chemical Change Lab
Students recognize both a physical and chemical change in different substances. They determine which particles actually changed into different substances, and explain if it represented a physical or a chemical change.
Curated OER
Lincoln's Secret Weapon
Students explore how principles of gas behavior relate to diving in order to plan safe underwater activities.
Curated OER
Kitchen Electrophoresis
Students investigate and explain the differences active transport versus passive transport. This lesson includes an individual and group activity. The basic steps of electrophores is the focus of inquiry. Identification of the pure...

How Do Scientists Research For Lab Activities?
Students explore the nature of scientific knowledge. They will also explore how to develop a lab plan to explain the structures of molecules and atoms. Research is essential to the success of the lab using necessary educational software.
Curated OER
Individual Gas Laws
Students learn the relationships between the different properties of a gas and use previous knowledge and make predictions. They predit and explain certain phenomena of gases using their chemical knowledge.
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.
Curated OER
Set the Stage
Students observe evaporation in a controlled environment. Evaporation is the change of liquid water into water vapor (a gas). The rate of evaporation is determined by many factors such as air temperature and humidity, liquid temperature...
