Metamorphic Rocks
Rocks can bend? Pupils investigate how heat and pressure produce metamorphic rocks by modeling them using clay, and then categorize samples based on observable characteristics. The lesson ends with a metamorphic rock identification...
Curated OER
Changes in Nature
Fifth graders identify the chemical and physical changes in the water cycle, carbon cycle, and the effects of weathering. They analyze the periodic table, and observe how vinegar reacts with limestone in a chemical reaction that causes...
Curated OER
Changes in Nature
Fifth graders explore changes in nature. They identify chemical and physical changes in the water cycle, carbon cycle, and weathering. Students explore a chemical or physical change based on a chemical formula. They examine the effects...
Curated OER
Nothing New? A Physical Change
Fifth graders discuss the differences between chemical and physical changes. In groups, they complete experiments and discover how a physical chnage can be reversed. To end the lesson, they review the steps of the water cycle and...
Curated OER
Icecream in a Baggie
Students apply their comprehension of colligative properties to real-world situations. They review the concepts of physical and chemical changes. Students are reminded that science is used extensively in food-production. They are...
Curated OER
Ice Cream Chemical and Physical Changes
Fourth graders identify characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and that these properties can be used separate. Students describe the...

Weathering of Limestone
We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...
Curated OER
Rocks and weathered rocks
Students connect rock and mineral formation with the changes rocks and minerals undergo at the earth's surface. They observe changes produced by weathering and relating these observations to chemical processes such as oxidation,...
PBS
Breaking it Down
After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...
Curated OER
State Change
Eighth graders explore the physical change of matter. As a class, they discuss their favorite super hero and determine if the hero undergoes a physical or chemical change. Students examine the change of state and phase change. In groups,...
Curated OER
Eggs'ceptional Experiments
Students see evidence of chemical reaction and follow the scientific method to hypothesize, observe, and reach conclusions. They conduct a series of egg based experiments such as forming crystals and complete journal activities as a...
Curated OER
Reversible and irreversible changes
Students define the words "reversible" and "irreversible." They complete a worksheet that shows a number of changes. Students must decide which are reversible and which are irreversible.

Mad Science Lab: Original Lesson Plan
Students conduct a number of simple experiments, collect and categorize the results as either chemical or physical change. The lesson uses connections to folklore, science fiction and comic books to assist each student as they make...
Curated OER
States of Matter and Chemical/Physical Changes Stations
Learners break into four groups, starting at different stations. Each station should take about 10 minutes depending on prior knowledge of the topic. They then rotate when everyone is finished to the next station and discuss answers of...
Curated OER
Dust in the Wind; Chemicals in the Water
Students explore mechanical and chemical weathering at stations. They articulate some mechanisms of chemical and mechanical weathering through exploration in a lab. Students stations describe how chemical weathering differs from...

Climate and Forest Ecosystem Services
Forests, through sequestration, capture excess carbon dioxide in our atmosphere and store it, aiding in climate change. The third installment in a four-part series on how climate impacts forests explores carbon sequestration....
Curated OER
Sedimentary Rocks
Fourth graders discuss the basic properties of rocks, the processes
involved in the formation of soils, and the needs of plants provided by soil. They write descriptions in their Science journal and identify and discuss each type of...

A Model of the Rock Cycle
In this rock cycle worksheet, young scholars use different colored crayons to represent different types of rocks. They follow step by step procedures to model the rock cycle with the crayons. Students draw the rock cycle, show...
Curated OER
The Changing Earth
Students observe and analyze weathering. In this earth science lesson, students demonstrate physical and chemical weathering in two experiments, then write questions for a class Jeopardy game.
Curated OER
Climate Change: Is there a Controversy
Students explore climate changes. In this climate changes instructional activity, students research what causes changes. Students search the Internet, summarize reports they find and create a poster with the information.
Curated OER
Breaking it Down
High schoolers will identify the factors that contribute to erosion and weathering. They will start by differentiating between chemical and mechanical weathering. They then apply what they learned by playing the online jeopardy game. Key...

Solubility and Chemical Changes in Groundwater
Students test pH of water before and after it travels through different substrates (igneous pebbles and limestone) to detemine how soluble materials can affect groundwater. They answer questions such as: What happended to the pH of the...
