Students find the mass, volume, and density of various objects. In this density measurement instructional activity, students observe how same-sized objects can have different masses, then use water displacement to find the density of...

Students experiment with a variety of liquids to calculate density. In this integrated science and math lesson plan, students listen to a story in which the characters must prove and explain why 5 "mystery" liquids react in a certain...

Students investigate matter. In this physical science lesson plan, students will learn about matter, physical states, and reactions. There are a series of four lab activities that will be conducted.

Learners explore water density and design a hydrometer to measure density. This activity is part of Ocean World's home site and excellent resources and links are provided.

A micro-unit on the phase changes of water includes three laboratory activities. Junior scientists compare the densities of ice and water, and then they do the same for cold and warm water. They examine freezing and boiling temperatures....

Students explore the meaning of density. In this density lesson, students use interactive whiteboards to review definitions regarding density and compare the density of selected objects.

Students identify different woods based on their density. In this density lesson, students use a triple beam balance to find the mass and a metric ruler for the volume. They look through various wood blocks and identify what type of wood...

Students examine the effects of temperature and density in ocean currents. In this density lesson, students explain how coastal climates are impacted by ocean currents. They investigate how the ocean currents are affected by temperature...

Students explore the concept of density. In this density lesson, students determine the density of various objects. Students use the density of the various objects to predict the density of various unknown solutions.

Students discover density.  In this density lesson, students discover the properties of objects that allow them to float or sink in water.

Students observe teacher demonstrations that illustrate density. For this density lesson, the teacher demonstrates how air bubbles in a carbonated drink can cause a raisin to float and how an egg sinks in fresh water, but floats in salt...

Students experiment floating a variety of objects in various liquids. They discover how density affects the ability of an object to float and apply the concept of density to solve problems.

NASA presents a mini-unit on distances in our solar system. It incorporates scientific concepts of gravity, mass, density, and payload while your aspiring astronauts also employ mathematics skills. They calculate speed, they determine...

All soil is not created equal! A lab activity asks learners to collect and analyze soil. Specific calculations determine the amount of sand, silt, and clay in a sample and allow individuals to identify the soil texture. 

Tenth graders investigate the carbon monoxide level at a fixed latitude. They determine if there is a relationship to population density. They download data sets and generate a graph. They determine a link between human activity and...

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 instructional activity of six from NOAA....

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

Swirling and churning, the waters of the North Atlantic play a vital role in Earth's climate! Discover the many factors that produce circulation using a multimedia instructional activity from PBS's Weather and Climate series for high...

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

Middle schoolers analyze given data on density and diameter of objects in space by graphing the data and then discussing their findings. This ninth installment of a 22-part series emphasizes the Galilean moons as compared to other...

How is it possible for ocean water to have layers? The sixth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates factors that cause different water densities to occur. Experiments...

Use this art lesson to study insolubility and density. Combining water-based paint and mineral oil will cause a fun and interactive painting. This is a great art project to incorporate during a science unit.

Junior chemists manufacture biodiesel in the lab. In this exercise, they check the purity of the biodiesel using thin layer chromatography. They also calculate its density and heat of combustion. They are sure to rise to the...

Fifth graders apply the concepts they know regarding mass, volume and density in the previous activities to design a boat. Student teams must make a boat which can travel the waters of the Amazon Rainforest. Each group makes a...
