The Big Balancing Act
Students describe chemical changes occurring in hydrothermal circulation systems. They make inferences about the significance of these systems to ocean chemical balance compared to terrestrial runoff.
Curated OER
How is a REDOX Reaction Used to Power a Car?
Students explore electrolysis and Redox reactions. For this exploratory lesson students demonstrate an example of electrolysis and how it brings on a chemical change.
Curated OER
What's the Matter with My Orange?
Students use oranges to informally explore decomposition, dehydration, fermentation, the water cycle, bacteria, yeast, food webs, the needs of living things, and physical vs. chemical change over a period of three or more months.
Curated OER
Transfer of Thermal Energy
Students define temperature and heat, distinguish between temperature and heat flow, calculate amount of heat energy released or absorbed in chemical process, and design procedure, through experimentation, to gather and evaluate data to...
Curated OER
What is Matter?
Students investigate what matter is and how it changes states. In this physical properties lesson, students examine the vocabulary database and identify the characteristics of the three phases of matter. Students perform a liquid vs....
Curated OER
Chapter 3 Worksheet Matter
In this matter worksheet, students answer ten questions about matter including the phase of matter, mixtures and how they are different from compounds, the physical and chemical properties of matter and the difference between homogeneous...
Curated OER
Enzymatic Action
Students observe how a cell uses an enzyme to rid itself of a poisonous substance by experimenting with hydrogen peroxide, potatoes, liver and carrots. They record the temperature and changes of the hydrogen peroxide as other elements...
Curated OER
Mixed Review-Chemistry
In this chemistry review activity, students answer a variety of questions about matter, elements, the kinetic theory, chemical and physical properties and the distillation process. They complete a concept map about matter.
Curated OER
pH Scale, acids and bases
Eighth graders define the pH scale, acids and bases. They distinguish between acidic and basic solutions using litmus paper. Students review simple chemical formulas. They define the subscript and coefficient in terms of chemical...
Curated OER
Falling Into Leaves
Students investigate why leaves change color. In this chlorophyll lesson, students examine how chlorophyll effects the color changes in leaves. Students take pictures of changing leaves, and create a class quilt showing the changes of...
Curated OER
Investigation 3 - Weathering
Fourth graders study 4 types of weather processes: wind, running water, plant growth, and freezing water. They explain how the processes of weathering and erosion change and move materials that become soil. They draw diagrams...
Curated OER
What's the Matter with My Snow?
Students collect snow samples around their school. They explore the concepts of density and phase change as well as the math skills of measurement and statistics. Students explore the water cycle through an interactive, down loadable...
Curated OER
States of Matter
Students examine the properties of solids, liquids, and gasses. In this states of matter lesson plan, the teacher guides students through a series of experiments to illustrate each state of matter and how matter changes from one state...
Curated OER
Mixing Colors
Fifth graders perform experiments with color mixing and color changing. They observe the differences between physical and chemical changes and record their observations in journals.
