Lesson Five: The Earth, Rocks and Minerals
Apply the principles of geology to a series of collaborative, hands-on class activities. Young earth scientists learn more about igneous, metamorphic, and sedentary rocks before classifying and weathering rocks that they find....
Curated OER
Coal Flowers
Students observe the effect of various chemicals on coal. Using coal, laundry bluing, water, salt, and ammonia, they observe crystal formations after a period of a few hours, and discuss their observations.

The History of Creation
Students explore the properties of matter. In this lesson about matter, students will do a series of experiments to enable them to understand about creation of the universe. In these some of the experiments students will makes stars,...
Curated OER
Minerals
Students define the characteristics of a mineral. In this geology lesson, students are given out various materials to observe such as a chicken bone, salt shaker, white paint, and chalk. Students categorize the items and are told what...

Solutions, Suspensions, and Colloids
In this solutions, suspension, and colloids worksheet, middle schoolers answer questions as it relates to their reading information about solutions, suspensions, and colloids. Students observe different examples and complete a chart as...
Curated OER
Sea Ice
Students observe the freezing times and temperatures of water with varying levels of salinity. They determine how icebergs form, how they act, and what they may be made of. They discover that salinity level affects the time it takes...

How Organisms Respond to Changes in their Environment
High schoolers observe the reaction of living cells to mechanical and chemical stimuli by introducing different stimuli to an organism under a microscope and recording the response.
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.
Curated OER
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.

Ice Cream
Students explore the concept of the colligative property. Through experimentation, students lower the freezing point of a liquid in order to create a solid by using household ingredients to create ice cream.
Curated OER
Quick Freeze (Demonstration)
Students witness an demonstration in which a bottle of club soda will go from a liquid to a solid when it is opened and the carbon dioxide is allowed to escape. This will help them understand that the freezing point of a solution will...
