Curated OER
pH Change and Brine Shrimp eggs
High schoolers determine if brine shrimp eggs hatch and develop more readily in an environment which has an acid or a basic pH. They evaluate the pH level which is optimal for the hatching and development of brine
shrimp.

Organic Materials in an Aquatic Ecosystem
Pupils evaluate the relationship between oxygen levels and the amount of organic matter in an aquatic ecosystem. They explain the relationship between oxygen levels, bacteria and the breakdown of organic matter using an indicator solution.
Curated OER
Multiplying Microbes
Learners examine environmental conditions that effect bacteria growth. They culture bacteria, design and conduct an experiment, and identify the conditions that effected the bacteria growth using the scientific method.
Curated OER
Franklin Mountains
Students review the steps of the rock cycle. In groups, they identify the natural forces that cause weathering and erosion. They describe how sedimentary, metamorphic and igneous rocks might be formed in nature to end the lesson.

Molar Ratio
Students conduct an experiment in which they react sodium bicarbonate with hydrochloric acid to determine the molar ration between the two reactants. Students must write correct formula and a balanced chemical equation and explain how...
Curated OER
The Importance of Water
Students explore the importance of water. They discuss why water is important and students design an experiment that evaluates the water quality and methods of improving water quality. Students perform testing and report their findings.
Curated OER
Transpiration
Pupils explore what affects the rate of transpiration in plants. They measure the rate of transpiration and analyze variables and additional factors that might slow or speed up the rate of transpiration.
Curated OER
Painter's Area
Students demonstrate geometric relationships of finding area of rectangles and squares. They apply determine the quantity of paint needed to cover the area by using the concept of quantity.
Curated OER
Cracked Marbles
Fourth graders determine how weathering, specifically ice, snow, and freezing water change the Earth's surface and rocks. After completing the investigations, they explain how heating and cooling expand and contract marbles until cracks...
Curated OER
The Penny Factory
Fourth graders identify the characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and separate or sort items using these properties. Students explain...
Curated OER
Determination of the percentage of Acetic Acid in Vinegar
Students determine the concentration of acetic acid when the concentration of the base with which is titrated is known. They investigate how to weigh a sample using the balance, measure volumes using graduated cylinder, explore the...

Graphing Your Motion-Day 1
Ninth graders explore the concepts of motion, velocity and acceleration through graphing their own movement using LoggerPro. They become more familiar with the computer technology. Students explore graphing in real time and graph on...
Curated OER
Animal Kingdom: Phylum Chordata
Students use a dichotomous key to classify various vertebrate jar speciments into classes. They examine the speciments for general characteristics of each class and fill in a corresponding chart and then complete a few final assessment...
Curated OER
Exploring Ecology
Students explore the basics of ecology through numerous hands-on and relevant activities. They participate in an online food chain demonstration, which explores food web dynamics. They dissect owl pellets, examine the prey's bones, and...
Curated OER
Hyperbolas
Learners find the center, foci, vertices, and asymptotes of hyperbolas. They graph hyperbolas and determine the equation of a hyperbola with a horizontal transverse axis. They derive general coordinates for the foci of a hyperbola with a...
