What Floats Your Boat?
Clay's as good a material as any to build a boat, right? An introductory lesson sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats to measure the...
Curated OER
Density
Learners predict when an object will float or sink based on comparison of density of the object to the density of the substance in which it is placed. The access a website and sketch the object in the first column of their table and then...
Curated OER
Density in Relation to Float and Sink
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.

What Floats Your Boat?
Middle schoolers are introduced to the concept of buoyancy. The Video used in this lesson demonstrates and explains the characteristics of objects that sink and float. It presents the concepts of displacement, weight, and buoyancy.

Floaters and Sinkers
Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...
Curated OER
Sink or Float
Students explore water properties by conducting a class experiment. In this buoyancy lesson, students make predictions as to whether or not specific objects will sink or float in water. Students conduct the experiment and record their...
Curated OER
I'm Warm Now
Third graders graph how much water is wasted while waiting for it to get warm in the spigot in the sink. For this graphing lesson plan, student first predict how much water is wasted. That night they test it out at home and the next day...

Determining Densities
Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...
Curated OER
Heavy Ice: Day Five
Learners explore physics by conducting a class experiment. In this density lesson plan, students examine a list of items and discuss whether they will sink or float and then determine their density. Learners examine the objects over five...
Curated OER
Day Six: Floater What Ifs
Young scholars observe earth science by examining results from an experiment. In this buoyancy lesson, students practice floating different items in two different liquids and identify why certain objects will float and others sink. Young...

Regular Coke vs. Diet Coke: Which is Denser?
Learners define the terms "mass," "volume," and "density." The relationship between these three terms is established. They observe the differences between Regular and Diet Coke. They develop an hypotheses about why a can of Regular Coke...

Clay Boats
Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

Buoyant Boats
Eureka! Using the clay boats made in the previous lesson, learners investigate the idea of buoyancy and water displacement to finish the last installment of five in a Floaters and Sinkers unit. Their observations during the activity...
Curated OER
Sink or Float?
Students predict and explore to discover which objects sink or float in fresh and salt water, predict how salt affect objects, write predictions on T chart, discuss difference between man-made and natural waters, and graph results.
Discovery Science Center
Kindergarten Observing, Comparing and Contrasting
Although this is a science lesson, it can be adapted to help meet Common Core standards in math as well. Starting scientists describe physical properties of objects and explore three forms of water. To address the Common Core, they can...
Curated OER
Regular Coke versus Diet Coke, Which is Denser?
Students investigate the density of liquids. In this geometry lesson, students calculate the volume and differentiate between volume, mass and density. They observe similarity and differences between coke and diet coke.
Curated OER
Pumpkin Science
Students investigate how plants grow by analyzing pumpkins. In this agricultural lesson, students read The Biggest Pumpkin Ever by Steven Kroll, and draw pictures of a pumpkin in each of its growing stages. Students measure and dissect...
Curated OER
Boat Design
Young scholars build a boat and make predictions. In this geometry lesson, students design a cargo boat. They must show that the boat they designed can carry the cargo.
Curated OER
Buoyant Force
Students illustrate Archimedes' Principle of Buoyant Force. In this graphing activity, students will observe that the buoyant force on an object is equal to the weight of the fluid it displaces. Students will then create a graph showing...
Curated OER
Density Destiny
Sixth graders measure and investigate the densities of several objects. They, in teams, determine the mass and volume of each of the 5 objects and record the measurements in the data table.
Curated OER
Pumpkin Circuit
Learners complete a variety of activities using pumpkins. They visit various stations with various pumpkin activities.

Mystery Liquids: Linear Function
High schoolers determine the linear equations of the density of water and oil by collecting data on the mass of various volumes of each liquid. They construct scatter plots from the data and use these to write the linear equations for...
