Density
Second graders watch a demonstration and complete an experiment to determine how an objects' density allows it to float or sink. They work in small groups to assimilate the characteristics of items that float as opposed to simply...
Curated OER
Density of Liquids
Pupils apply knowledge about density of solids from previous experimentation to this activity which they investigate the density of liquids. They work in small groups to mix water and syrup, and water and oil to see what occurs. Finally,...
Curated OER
Denser Sensor
Fourth graders calculate density, compare densities of solids and liquids, measure liquids using a balance, and investigate the significance of density. They conduct an experiment to determine an order of densities, and complete a...
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,...
Curated OER
Population Density In Fish
Middle schoolers investigate how a population of fish multiplies in an ecosystem and the kinds of things that must be done to maintain a healthy population balance with other organisms that live there. They conduct an experiment to test...

Pumpkin Properties are a Smash!
Learners receive a miniature pumpkin and proceed through several stations to measure a variety of physical properties. The data is entered into a data sheet and the mass and volume measurements are used to calculate density. They also...
Curated OER
Comparing the Density of Iron
Learners use scientific measuring tools to collect and use scientific data. They determine the density of four different objects by using their data to explain why objects have similar/different densities even though they are both made...
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
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...
Curated OER
Density of Solids and Liquids
Pupils calculate the density of regular and irregular solids and liquids. They relate the term dense to science as well as its literal meaning that society uses it as everyday. A worksheet is completed on density.
Curated OER
Properties of Matter/Comparing Mass, Volume and Density
Students 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...
Curated OER
It's OK to Reach Your Boiling Point!
Students view a video which introduces them to density and the states of matter. They experiment, collect data, and graph the boiling/freezing points of several edible items...and then make brownies!
Curated OER
Sampling and Comparing Biodiversity
Young scholars compares the density and distribution differences of four species of spiders in two hypothetical habitats. They "sample" two habitats and then do calculations such as average density and relative distributions to compare...
Curated OER
8th Grade Earth Science: Density
Students draw upon their prior knowledge of the density of water and practice writing a hypothesis, making an observation, and analyzing data while watching a density demonstration.
Curated OER
Density Lab Activities
Students participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.
Curated OER
"Eggs-perimenting" Fun
Learners dissolve salt into water, place an egg into a glass of salt water, observe and record observations, make a scientific hypothesis, summarize what they studied from this hands-on experiment. They share their ideas and findings...
Curated OER
Classifying Materials
Students collect data and make observations on how given element samples respond to the field of a magnet and they calculate the density of the samples by finding the mass and volume.
Curated OER
Powder
Pupils investigate several unidentified substances and suggest a use of each substance. They can explain that a substance has characteristic properties, such as density, a boiling point, and solubility, all of which are independent of...
Curated OER
Blue
Pupils follow directions for a simple chemical experiment. They use the appropriate tools and techniques to gather, analyze, and interpret data. Students identify a substance that has characteristic properties, such as density, a...
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
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...
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.
Curated OER
Aluminum Foil Boats
Pupils design a boat of aluminum foil and calculate the density of the boat. Washers are added to the boat until it sinks. Students then redesign boat to hold more washers and recalculate the new density.
Curated OER
The Causes of Differences in Density
Students explore how density changes. Students read an article on density. They observe a ball and ring demonstration and discuss the outcome. Students draw models of the demonstration and explain what happened.
