Defining Density
Three simple activities kick off a unit investigation of density. Your physical scientists make observations on the volume and mass of wood, water, and rocks, and make comparisons. Though this is written for grades three through eight,...

Float or Sink?
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...

Density
Students find the mass, volume, and density of various objects. For this density measurement lesson, students observe how same-sized objects can have different masses, then use water displacement to find the density of each object and...

Activity #7 Mass, Volume and Density
Learners comprehend that density depends on the type of material and not on the amount of material. They use a spoonfl of table salt and a box of table salt and have the same density. Pupils comprehend that density is calculated by...

Activity #4 The Density of Irregularly Shaped Solids
Students comrehend that water displacement is a simple way to measure the volume of a solid object. They pour water into a graduated cylinder or measuring cup and its volume is read and recorded. Pupils the volume of an object by...

Density - An Intrinsic Property
Learners discover the property of density while participating in a lab exercise. In this scientific measuring instructional activity, pupils utilize a scale to measure the density of different metal materials. They document their work...
Curated OER
Density Discoveries
Students participate in Density Discoveries, which is a hands-on learning opportunity for students to find the mass, volume, and density of solid matter.

Will It Sink Or Float?
Have your class predict whether objects will sink or float in water. Learners consider a data table of mass, volume and whether the object sank or floated. They develop an evidence-based explanation for the results.
Curated OER
Density of Minerals
Young scholars determine the mass, volume, and density of two different mineral samples. Students show data and calculations as well as answer questions about the mineral identities.

Comparing Densities of Different Liquids
Students experiment with a variety of liquids to calculate density. In this integrated science and math lesson, students listen to a story in which the characters must prove and explain why 5 "mystery" liquids react in a certain manner....
Curated OER
As a Matter of Fact
Elementary-aged scientists discover that all matter has mass. They are shown the difference between mass and weight, and learn how to calculate mass using the appropriate tools and methods. The scientific method is used while estimating...
Curated OER
Exploring Buoyancy
Learners use materials found at a resource table to design simple devices that will house instruments to take water samples from a tub of water. They design 3 instruments, each varying in density so that one will float, one will hover...
Curated OER
Why Do Some Things Float?
Students recognize that density determines whether objects sink or float. In this sink or float lesson, students experiment with plastic in three liquids. students drop their objects into the liquids and observe and record their results.

Visualizing Density: Density is Non-obvious
Students explore models of density; wooden balls and marbles discussing whether they think the volume and mass are the same or different. They then compare the density of a loaf of bread that is squished and one that is not compressed.
Curated OER
Estimation Task
Upper graders practice their estimation skills by observing different objects then making their best guess without using measuring instruments. Students are asked to estimate mass, length, volume, and area.
Curated OER
Activity #3 Finding Mass
Learners use graph paper to construct a graph and determine the slope of a straight line. They determine the weight (mass) of paper clips with a pan balance. Pupils weigh an unknown number of paper clips, and to interpret the graph to...
Curated OER
Diving Raisins
Students hypothesize and observe what occurs when raisins are dropped in a carbonated liquid. They examine buoyancy and how density effects ascent and descent.
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
Characteristics of Matter
Students study matter. In this science lesson plan, students examine the relationships among gravity, weight, and mass, the metric measurement of distance and volume, and density and its application to physical properties.
Curated OER
Big Enough?
Students explore the concept of density and buoyancy. In this physics lesson, students discover the different factors that affect an object's density and buoyancy in water. Students conduct several investigations to further understand...
Curated OER
Activity # 13 Float or Sink?
Pupils have seen that solids, which are more dense than a liquid, that sinks in that liquid and solids, which are less dense than a liquid, that floats on that liquid. They use a metal boat to float in water. Pupils comprehend that...
Curated OER
The Floating Golf Ball
Young scholars explore density by floating golf balls. They explore having their golf balls float halfway in a container of water and discuss density and its realtionship to where the golf balls are floating. After adding food coloring,...
