Curated OER
Acid and Base Testing
Pupils 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.
Curated OER
Acid and Bases - Alien II
Eighth graders determine which of two solutions is more acidic by adding each to a given base. Students have to apply this analysis process to a problem scenario involving an alien creature.
Curated OER
Get Down With Density
Students define density and observe that things that are less dense than water will float. Students find the density of copper, iron and aluminum
Curated OER
Rain Drops
Students examine drops of water on several materials used on the outside of buildings. They make selective observations on and compare plastic, wood, brick, metal, roof tiles and glass.
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
Food and Fiber: Helping the Environment and You
Fourth graders explore the many uses of corn-based products and the importance of water resources. They consider how biodegradable products help to keep water clean. They perform experiments to observe how corn pellets dissolve while...
Curated OER
Acids And Bases -- Universal Indicator
Eighth graders design and perform an experiment that uses a Universal Indicator Color Guide to measure the strength of acids and bases. They also determine happens when acids and bases are mixed together. They decide which of three...

Angles: Angles, Angles, Everywhere
Middle schoolers estimate and accurately measure the size of angles communicate with the appropriate geometric terms and symbols to describe and name angles, lines, line segments, rays
Curated OER
Fallout!
Students plot the locations of fallout from two disasters that polluted much of the world's air. They plot the ash fallout from the 1980 Mt. St. Helen's eruption to see what the wind patterns in the United States look like overall. Next...
Curated OER
Physical and Chemical Changes
Eighth graders distinguish between physical and chemical change. For this chemistry lesson, 8th graders observe a series of demonstrations showing physical and chemical changes. They identify the signs that a chemical reaction took place.
Curated OER
Losing An Island
Students examine carbon dioxide and determine the impact of greenhouse gases on the earths spheres. In this pollution lesson students complete a lab activity to see the impact of gases on the environment,
Curated OER
Wig-wag Physics
High schoolers make observations on the effects of a small, medium and large weight on the movement of a wig-wag apparatus. They use their observations to develop a generalized inference of the effect weight on movement patterns.
Curated OER
Nuclear Reactors
In this nuclear reactors worksheet, students use a diagram to match 28 words into a paragraph describing the parts of a nuclear reactor and what job they perform.
Curated OER
Float or Sink?
Students examine why some objects float while others do not. They place various objects in water to observe their floating capability. Students record the object, its weight, and if the object floated. They construct a graph plotting...
Curated OER
Converting Metric Units and Prefixes
Young scholars investigate the length of various objects. In this measurement lesson, students convert one metric unit to another. They explain the importance of a uniform system of measurement.
Curated OER
Physics Post-Lab
Students explore physics. In this science lesson, students discuss physics in their everyday lives. Students complete a physics worksheet.
