Curated OER
Glucose Factory
Fourth graders determine, through laboratory activity, the presence or absence of glucose in a variety of plant leaves and stems. They work in groups and perform a three part laboratory which shows them how plants convert sunlighht to food.
Curated OER
Mighty Minerals
Students investigate the physical and chemical characteristics of minerals. They make a list of the uses of minerals found in Illinois. They write a report individually based on their observations.
Curated OER
The Internal Anatomy of the Grasshopper
Sixth graders explore the internal organs of grasshoppers. They determine the function of the organs through a dissection activity.
Curated OER
Project Geode
Students predict the appearance of a geode's internal structure based on its mass and density. They form a hypothesis based on the data they collect. They also identify common minerals found in Illinois.

Does the Introduction of Pesticides and Fertilizers Alter an Aquatic Ecosystem?
Students conduct an experiment using a small sample from a local water source. They introduce fertilizers and pesticides, separately, and carefully examine the results in their simulated aquatic ecosystem.
Curated OER
HOW IS PH DETERMINED?
Students estimate the pH based on the use of an unknown substance, determine whether an unknown substance is acid, base or neutral, and evaluate, by the pH determination, which of the unknowns is the strongest acid or base.

How Dense Are You?
Learners examine how density is a value that describes what type of a material an object is made of regardless of its shape or size.
Curated OER
Physical Difference and Classification
Students use a microscope and observation skills to compare and contrast several physical properties and develop a classification system.
