There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

Archimedes' principle is practiced as chemistry learners practice computing the density of different gases, liquids, and solids. Using a chart of standard densities, they also identify unknown materials by similar calculations. Fifteen...

Middle schoolers investigate the role of temperature and salinity in determining seawater density. They use a Temperature-Salinity Diagram to examine the effects of mixing on density.

Not many lessons on states of matter can hold a candle to this one! Junior chemists gauge the density of paraffin in both liquid and solid phases. They fill 60 mL syringes with different materials to experiment with compressibility and...

Through a station rotation activity, scientists complete 9 chemistry activities to complete this interactive worksheet. Concepts include molar masses, percent composition, accuracy vs. precision, mass of an object, scientific notation,...

Investigating the large numbers of science is the task in a simple but deep activity. Given a one-sentence problem set-up and some basic assumptions, the class sets off on an open-ended investigation that really gives some...

Energy is just energy, right? Explain various forms of energy to your young scientists by using an interactive experiment that contains common objects to demonstrate complex concepts. Pupils conduct experiments for radiant, thermal,...

What do we do when a dive is too dangerous for humans to accomplish? Send in the robots! Middle school scientists get acquainted with several different models of submersible robots in the second lesson of six from NOAA. Lab groups then...

Ice is nice, and its condition on the planet has a significant effect. Junior geoscientists experiment with ice melting in both water and on land to discover how each affect the rising sea level. This detailed lesson outline even...

Students compare and contrast the mass, volume, and density of various objects. They use a triple beam balance, measure and record the volume of a cup of water, and discuss the results.

Pupils participate in a discussion of volume and density and then engage in a hands on lab. They weigh equal volume cubes at lab stations of an assortment of common substances in a lab setting and record data on their findings on...

Middle schoolers (teachers) complete the activity, they should not come in contact with Alka-Seltzer. They comprehend that the density of a gas can be calculated from its mass and volume. Pupils calculate the volume of gas generated by...

Pupils practice determining liquid densities in a short, hands-on lab activity. Students use a graduated cylinder to measure out 100 milliliters of a liquid, find its mass using a balance, and record measurements in a data table. Pupils...

In this measurement worksheet, learners identify the units of measurement, the instrument used to measure and the method used to measure weight, mass, density, volume and length. They also answer questions about measurements and find the...

Here is a planet worksheet in which learners read about organic molecules detected through spectral lines of the planet Osiris. They calculate the mass, the volume and the densities of common ingredients for planets including Osiris and...

It's all about density! Here's a dense workbook for young scientists; they solve (and show work for) 29 density word problems, including a problem where they solve for the density of Godzilla. They complete labs analyzing metal...

Who pilfered the pin? Scholars practice measurement skills as they solve the mystery of a stolen pin. They measure length, temperature, and mass and determine which of select suspects committed the crime. During the STEM hands-on...

Fifth graders determine volume and density through their knowledge of mass, volume and density.

Students observe a demonstration of regular soda versus diet soda.  In this exploring density instructional activity students complete a lab on density and present a PowerPoint presentations of their results.

In this density worksheet, students review how to calculate density and how to apply Archimedes' Principle, Boyle's Law, and Charles' Law. This worksheet has 10 matching, 13 short answer, and 6 fill in the blank questions.

For this density and buoyancy worksheet, students read about the equation to find density and practice finding the density of substances. They read about buoyancy and match 10 terms with their definitions related to density, buoyancy and...

For this density laboratory worksheet, learners complete 2 prior knowledge questions, then use the "Density Laboratory Gizmo" to complete several activities, answering short answer questions when finished.

Students participate in Density Discoveries, which is a hands-on learning opportunity for students to find the mass, volume, and density of solid matter.

High schoolers explore the causes of differences in density. Students choose objects, measure the mass and volume, and calculate the density of each. They perform additional density experiments to model atoms and their correspondence...
