Curated OER
Pond-water Populations
Young scholars design and conduct and experiment on algae, for a two week period, to answer the question "In your investigation, how does changing one factor affect the growth of organisms?"
Curated OER
Tree Growth
Students fill in a diagram. In this tree growth lesson plan, students view a model of a tree, learn how trees grow and explore the layers of a tree. Students complete a diagram where they label the layers of a tree.
Curated OER
Electromagnets
Students are introduced to the relationship between electricity and magnetism. Using a compass, they observe and record the effects of placing the object near magnetic fields and electric currents. They also experiment using a steel and...
Curated OER
Linkages Between Surface Temperature And Tropospheric Ozone
Students collect and interpret data to make predictions about the levels of ozone in the atmosphere. Using the internet to collect data students use their collected data to create a line graph for analysis. Students make mathematical...

Selecting Soil For a Sports Field
In this science worksheet, high schoolers take part in a laboratory exploration looking at different types of soil. The soil is evaluated in order to fill the role of becoming a sports field.
PBS
America's Infrastructure: Miller Center National Discussion Debate Series
Junior high and high school learners study infrastructure and its relationship to the current economy. They review handouts, watch a PBS clip, and review case studies in order to answer provided questions and role play over...

How Strong Is It?
Students investigate the adhesion conditions and surface for using post it notes. In this post it notes lesson plan, students discover the adhesive properties, test the notes for strength, and interpret data and draw conclusions.
Curated OER
Stratification
Learners study the process of stratification and seed dormancy. In this germination instructional activity students prepare a medium in which to grow seeds.
Curated OER
Sequence Alignment
Learners explore the uses of sequence alignment. In this DNA activity students complete several experiments on sequencing and algorithms.
Curated OER
Water-holding Capacity of Earth Materials
Students design and conduct an experiment to test their ideas about how to speed up or slow down the rate of an enzyme-catalyzed reaction. They have access to an array of physical and chemical factors that might influence enzyme...
Curated OER
Barometer Investigation
Students construct a barometer to use in an experiment that they design to measure the air pressure on a daily basis. These observations of air pressure allow students to determine how weather is affected when a storm is approaching and...
Curated OER
The effectiveness of Antacids
High schoolers design and conduct a scientific experiment to test which of four antacids would be most effective for neutralizing acids. They rank the antacids in order from most effective to least effective and explain how they...
Curated OER
That's the Way the Ball Bounces
Students investigate and compare the bouncing ability of the materials from which four different balls are made. They determine which material performs the best for use as a basketball. After collecting data in a small group they...
Curated OER
Rate of Cooling Experiment
Ninth graders measure the insulation properties of different fabrics by immersing cans of water covered with fabric "socks" in an ice bath and measuring temperature changes. They then calculate heat loss and graph the data individually.
Curated OER
The Nutritional Content of Food
Students are given three unknown samples and must perform two chemical tests in order to determine if the samples contains protein and/or starch. Students work with corrosive or toxic reagents.
Curated OER
Build an Anemometer
Students investigate wind speed. In this wind instrument activity, students build an anemometer to measure wind speed and discuss the importance of wind speed knowledge in various professions.
