Curated OER
Unknown Liquids
Learners must design and conduct an experiment to determine which unknown liquid has a greater density based on basic information about the liquids and containers. Students are given specific materials to work with.
Curated OER
Concrete Canoes
Students explore and analyze the relationship of buoyancy and displacement needed to make an object float. They examine various boat designs, then design and build clay and aluminum boats that hold a cargo of marbles.
Curated OER
Science of War
Tenth graders, from an environmental perspective, study the pros and cons of war. Distinctions between characteristics of biological, chemical and nuclear threats and the impact of economic development are considered.
Curated OER
Density of a Sinker
Eighth graders determine the density of a sinker by first finding the mass and then the volume using a graduated cylinder. Students must write the procedure they use to find the volume of the sinker then apply their data to follow-up...
Curated OER
The Awful Eight
Middle schoolers investigate the concept of a carpool and its contributions to either reducing or increasing air pollution. They conduct research using a variety of resources for background information. The information is used to write a...
Curated OER
Octopus Legs
Students have oceans of fun transforming a wienie into an octopus they can eat! After counting, cutting halves and fourths, observing steam and the effects of heat, they mix colors as they create a yummy dipping sauce from mustard and...
Curated OER
Catch a Dream
Students apply the concepts of air pressure, the Bernoulli Effect, and angle of attack to build their own model planes out of paper, plastic, wooden rods, and drinking straws.
Curated OER
Identifying Elements
Young scholars use diffraction glasses to find similarities and differences between observed spectrum of fluorescent light and an incandescent light They work in groups of 4-6 for the experiment/activity part of this exercise.
Curated OER
Acid Precipitation
Students test the acidity of unknown solutions. They use this information to make inferences from data given from recorded rainfall records to identify areas that receive the most acid rain.
Curated OER
Can You Make A Penny Float?
Students explore the concept of density by trying to make a penny and other materials float.
Curated OER
Synthesizing Pigment and Dyeing Cloth
Students create a synthetic dye and oxidize the dye and record the effects.
Curated OER
Paper Structures
Students demonstrate that material strength varies with shape and arrangement.
Curated OER
Oxidation And Corrosion
Students sort tarnished metals by type and experiment with different cleaning solutions and techniques to restore them to their natural color and shine.
Curated OER
Acid and Base Testing
Learners study descriptions of indicators and the way they are used to identify acids and bases. They use this information to determine if unknown solutions are acids or bases.
