Why Do Certain Things Float, While Some Sink?
First graders conduct an experiment. In this density instructional activity, 1st graders work in groups to test 10 different objects to see which ones sink and float. Students discuss why certain objects float and others do not.

Applied Science - Science and Math Post-Lab
Students explore optical illusions. In this Applied Science lesson plan, students view optical illusions and record the data of what they see. Students graph the data that they collect.
Curated OER
Density Currents
Learners study how fluids of differing densities interact with one another, how densities of fluids can be changed, and how density currents transport and deposit tremendous amounts of sediment in lakes and in the ocean.
Curated OER
Graphical Determination of Density
Students determine the density of metal shot by a graphical method using significant digits in making measurements and calculations. Students graph a seris of laboratory measurements and determine density from a mass verses volume graph.
Curated OER
Water Density Boundaries
Learners create observable layers in water that represent a separation based upon density differences. They model density boundaries using differences in temperature and salinity. They, in groups, perform a meaningful experiment...
Curated OER
Water Density
Students identify and analyze the concept of density using the formula, density equals mass divided by volume. They review the differences in salinity levels of the ocean and note that the changes in density are caused by wind and...
Curated OER
Immiscible Liquids and Density
Students will make a lava lamp. In this density lesson, students will combine water and oil and make observations, then add salt to the oil and observe the oil sink, then float again when the salt dissolves in the water.
Curated OER
Teacher's Guide For: Water Temperature and Salinity Experiment
Students experiment with water density, temperature and salinity. For this water lesson, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.

Circular Pave-Stones Backyard
Pack the lesson into your plans. Young mathematicians learn about packing and optimization with the context of circular paving stones. They use coins to model the paving stones, and then apply knowledge of circles and polygons to...
Curated OER
Population Biology
Students define the following terms: predation, competition, carrying capacity and population. They can explain the patterns of growth and the limitations of growth. Students explain the difference between density-dependent and...
Curated OER
Water Pressure in the Ocean
Young scholars compare the pressure of water at different depths and gain an understanding of how increased water might affect animals living in deeper waters. They participate in an experiment to show that depth, not volume, affects...
Curated OER
Give Me a Tall Ship
Sixth graders develop an understanding of floating, sinking, density, and buoyancy and apply it to the design of testing of ships.
Curated OER
Investigating Properties of Water: Temperature
Investigate how temperature affects the density of water and stratification that occurs in bodies of water when temperatures vary. Water of differing temperatures is given different colors to see the layers that form. The lesson is meant...
Curated OER
Examine Methods of Reporting Research Results
Students analyze a research report and the list of components needed in a research report and then identify those components based on a set of standards using the scientific method. They collect data which can be used for a graphical...
Curated OER
Adaptation and Diversity on Sheffield Island
Written for an exploration of shoreline ecosystems on Sheffield Island, this gives ecology or marine biology buffs a hands-on experience. Using GPS or visual triangulation techniques, they lay transect lines on a high and a low energy...
Curated OER
Biomanipulation
Young scholars explore the effects of aquatic trophic relationships on water transparency. They observe and explain the effects of reducing nutrient inputs on agal density on water transparency.
Curated OER
Physical properties of matter
Sixth graders find the physical properties of matter. In this matter lesson, 6th graders measure mass, volume, and density. Students are broken into 3 tiers with 3 different activities based on their understanding of mass and volume.

Vegetable Olympic Swimming: Will it Float?
Students inspect nutrition by conducting a science experiment in class. In this vegetable identification lesson, students examine a group of different veggies and predict whether they will sink or float in a tub of water. Students check...
Curated OER
Air Engine - Air Races
Students conduct an experiment about air volume, density, and pressure. In this air lesson, students discuss air, and how it moves. They make predictions about what will happen during the balloon and string experiment. They document the...
Curated OER
Force and Motion
Students experiment with force and motion. In this force and motion lesson, students test gravity using a variety of objects. Students rotate through a series of stations which use force, motion, friction, and inclines. Students predict...
Curated OER
Evidence of Chemical Change
In this chemical change worksheet, students conduct 4 experiments set up around the room. They follow the instructions at each station for each experiment and list the physical properties and observe any changes at each station. Students...
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
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...
