Curated OER
Heat from Light
Second graders explore solar energy. For this science lesson, 2nd graders use hand lenses to see that light energy can be converted to heat energy.
Curated OER
Mighty Minerals
Students identify the characteristics of minerals. They complete proper identification tests and record the data in an organized fashion. They list important uses for minerals as well.
Curated OER
No Bones About It
Students conduct Internet research on the different parts of the skeletal system. Then they create a model arm that demonstrates how muscle and bone work together to create movement.
Curated OER
Helpful Microorganisms
Students study how some microorganisms are helpful and practical in foods. They work with microorganism in a number of food, such as yeast in bread and yogurt.
Curated OER
Demonstration of Ideal Gas Law
You know that liquid nitrogen turns into a gas at room temperature. Place some in a two-liter bottle for a physics demonstration of the ideal gas law. Beware, however; this is a dangerous demonstration! Not to mention that you may not...
Curated OER
Tie Dye
High schoolers practice writing research proposals to test the color fastness of a dye once it has been exposed to a t-shirt. Each proposal needs details of experimental design, length of treatment, and means of cleaning the shirt. All...
Curated OER
The Chemistry of Refining Crude Oil
Consider our energy sources: wood, coal, oil, uranium. Learners compare the pollution to energy produced for each. They practice fractional distillation of an alcohol/water mixture to simulate the process of refining crude oil....
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
Acid Rain
Students perform experiments to determine how different acids cause acid rain. They measure the pH of the water to calculate the water's acidity. They discover how acid rain dissolves rock materials.
Curated OER
Roll with the Punches: Depression Era Machinery
Students construct models of simple and complicated machines with Legos. Then they design an experiment using the scientific method. ESE modifications included.
Curated OER
Change It
Fourth graders expand their knowledge about how the physical properties of a substances can be changed. They are given multiple opportunities, using first-hand experiences and familiar objects in different contexts, to identify...
Curated OER
Dissolved Oxygen in an Aquatic Ecosystem
Students explain why dissolved oxygen is important in aquatic ecosystems. They evaluate the optimal dissolved oxygen levels for living organisms.
Kenan Fellows
Industrial Knowledge of Acids and Bases
Over a 10-year period, EPA regulations cost businesses less than $30 billion, while businesses saved over $82 billion. Scholars experiment with acids and bases to better understand the pH scale. Then they debate environmental regulation...
Curated OER
An Introduction to Microbes and Microbes Are Everywhere
Seventh graders define the term microbe. They identify the five main groups of microbes. Students give examples of ways in which microbes have impacted or currently impact human life. They create a hypotheses for where they expect to...
Curated OER
Plant and Animal Cells
Students investigate the difference between plant and animal cells. They observe a variety o plant and animals cells by looking at a piece of cork, an onion, elodea, prepared slides of paramecium, human bone, frog blood, and human...
Curated OER
Physical/Chemical Properties of a Burning Candle
Students investigate the physical and chemical properties of a candle before and after it is lit. They conduct a burning candle experiment, and complete a KWL chart and worksheet, recording the results of the investigation.
Curated OER
The Average Atom - Isotopes
Seventh graders, in groups, complete an Isotopes model and notice that atomic masses are decimal numbers. These masses are an average of all the isotopes of that element.
Curated OER
Boom and Fizz
Learners investigate the differences between a physical and chemical change. They observe various demonstrations involving physical or chemical changes, make predictions, and record what they see, hear, and smell.
Curated OER
Candy Cane Chemistry
Fourth graders, in groups, examine the effect of heat on bonding forces by doing laboratory work.
Curated OER
GUM: More, Less, or the Same?
Pupils confirm the law of conservation of matter by weighing chewing gum before and after it is chewed.
Curated OER
Endothermic or Exothermic That Is the Question
Students conduct an experiment to determine what happens to heat energy during a chemical reaction. They examine an endothermic reaction by observing a chemical reactions.
Curated OER
What Is the Freezing Point?
Students remove heat energy and determine how it causes a phase change.
Curated OER
Acid Rain
Learners create acid rain using carbonic, nitrous, nitric, and sulfurous acids.
Curated OER
Chemical or Physical?
Fourth graders make observations of the reactions that happens between calcium carbonate and various liquids. During the experiment the students determine if there is a chemical change, a physical reaction, or no reaction when they mix...
