Are Our Chemical Measurements Accurate or Precise?
What is the difference between accuracy and precision? This worksheet has students define the terms accuracy and precision, and compare bulleye diagrams to find examples of both. Students analyze given data and determine the accuracy and...
Curated OER
Are You a Trend Setter?
Learners are introduced to the periodic table of elements. They devise and perform and experiment in which they determine the density of specific elements. They use their results to predict the density of other elements in the same group.

Weighing a Dinosaur
Students role play as paleontologists who make inferences about the weight of dinosaurs. They use models and the density of water to make these inferences.
Curated OER
How Big is a Molecule?
Students calculate the size of a molecule. For this molecules and their sizes lesson plan, students find the size of an oleic acid molecule by using a measured amount of drops of oleic acid to find the volume of the sample, the thickness...

Water Density and Stability Lab
Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.
Curated OER
Salinity Lab
In this salinity worksheet, students simulate conditions of salt and fresh water mixing and observe the various densities of these solutions based on their salinity.
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
i-Density Crisis
Eighth graders determine the density using mass and volume. For this science lesson, 8th graders explain why some materials float or sink. They estimate the density of objects based on whether it floats or sinks in a liquid of known...
Curated OER
More Volume Please! Don't Be Dense!
Fifth graders determine volume and density through their knowledge of mass, volume and density.
Curated OER
Biocomplexity Lab Activity: Density and Buoyancy of
Students investigate how the density of water changes the buoyancy of
water. Students create a hypothesis about what will happen when placing the
egg into the water.Students can research online different bodies of water (The Red Sea, The...

Supernova Chemistry
By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...
Polar Trec
Do You See What Icy?
Here is a lesson that kicks off with a question. "How does ice floating on the ocean act as it melts?" As learners investigate this natural phenomenon, they'll discover that it has a lot to do with temperature, salinity, and the effect...
