Oil Spill
Young scholars use one of four absorbent products to separate as much of the oil and water mixture they are able to do. The purpose of this task is for students to collect and analyze data for the purpose of determining which absorbent...
Curated OER
Acid-Base Titration
Students determine the concentration of an unknown solution. This task assesses students' abilities to state hypothesis, develop procedures for investigation, plan for recording and organizing observations and data, collect data, create...
Curated OER
Strong as the Weakest Link
Students discover the types of stress that materials undergo. They examine how bridges and skyscrapers are built to withhold the tension. They create their own structure out of marshmallows and spaghetti.
Curated OER
Sound And Motion
Pupils investigate the concept of sound and vibration. They use a tuning fork to make an observation. Students then propose the ideas of different experimental designs to test the concept. The ideas are constructed and then tested.
Curated OER
Atmospheric Cells
Young scholars recognize that the sun is the source of energy driving atmosphere cells. They relate the motion of the atmospheric cells to mantle convection cells. Students recognize that the function of atmospheric cells is to move heat...

To Float or Not to Float - A Lesson on Density
Students observe and experiment with the concept of density. This is done using a simple experiment that helps them to apply scientific principles of observation and proving a hypothesis.
Curated OER
Operations with Decimals
Teach your learners to solve word problems. They will review how to add, subtract, multiply, and divide with decimals. Then they solve multiple problems.
Curated OER
Diamonds Are Forever - Most of the Time!
Students examine the compositions and structure of diamonds. They conduct an experiment growing crystals, watch a video, and conduct Internet research.
Curated OER
Which Brand of Air Freshener is Most Cost Effective?
Students use scientific method to determine cost-effectiveness of air freshener, and create PowerPoint presentations to share their results.
Curated OER
Horns or Antlers-You Decide!
Students study the difference between horns and antlers. They identify animals who have each and draw pictures of these animals. They experience samples of actual horns and antlers.
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
Skyscraper Capers
Pupils discuss skyscrapers and listen as the teacher introduces the project. They use the Internet to perform research on one skyscraper. Students use information they gather to create a brochure of their building . They create an Excel...
Curated OER
Rain Drops
Middle schoolers 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
Angles: Angles, Angles, Everywhere
Students 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
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
Sort It Out
Students study classification systems by sorting Legos and determining how the different pieces are classified. They list as many attributes as possible to use for sorting.
Curated OER
Paper Structures
Students demonstrate that material strength varies with shape and arrangement.
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
SLIME!
Young scholars learn the effects of friction and examine how certain lubricants can only be used with certain materials.
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
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...
