The Chemical Nature of Water
Seventh graders simulate a Jeopardy game to examine the chemical nature of water. Among the topics featured are evaporation, water, salt, and temperature. finally, as review, 7th graders answer a battery of questions presented by the...
Curated OER
Unknown Liquids
Students 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
Packing Materials
Students observe the effects of water on four different packing materials to determine which ones are more soluble. They then decide which material would be a good packing material to use for the environment and which may be a bad...
Curated OER
Volcano!-Thar She Blows!
Students describe how volcanoes are formed. They name the types of boundaries where volcanoes occur. They utilize models to illustrate the occurence of volcanoes and earthquakes along plate boundaries. They compare and constrast the...

Chromatography
Students study about chromatography, a process used to separate mixtures.
Curated OER
Paper Chromatography
Small groups of learners perform paper chromatography to separate food dyes into their component colors. Students perform the experiment and collect, organize, and represent their data to form an explanation of their outcomes. Learners...
Curated OER
Blindfolded Building
Students build a Lego design and then work with a partner to reproduce that design. They guide the building of the reproduction by description only and then check their work.
Curated OER
Colored Dots 1
Students observe that colored markers are a mixture of many different colors by performing a chromatography experiment. They make observations, record information, and make generalized inferences from their observations.
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...

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
Atmospheric Cells
Students 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 from...
Curated OER
Sound And Motion
Students 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
To Float or Not to Float - A Lesson on Density
Learners 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.
