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...

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
Density and Buoyancy Experimental Design
Learners must plan, design, and conduct an experiment that answers the scientific question: "Come up with a question that addresses the factors (variables) of the water and its effect on whether an object floats or sinks."
Curated OER
Soap, Wood, and Water
Students measure the properties of two different types of soap and wood and calculate their densities. Then they predict whether or not whether or not each object would float or sink in fresh or salt water.

To Float or Not to Float, That is the Question?
Ninth graders develop operational definition of density, do computations using density equation, categorize pieces of matter as being able to float on
water or not, based on density, explain why some objects sink or float based on...

Density: Floating, Sinking, and Suspending
Students observe teacher demonstrations that illustrate density. In 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...

Changing the Density of an Object - Adding Material
For this sixth of seven activities revolving around the concept of density, physical science fans figure out if anything can be done to change the density of an object. Demonstrate by placing a can of regular and a can of diet soda into...
American Chemical Society
Changing the Density of an Object - Changing Shape
Continuing with the concept of volume and its effect on density, learners now work with a piece of clay to see if they can get it to float in water. This is a memorable end to a seven-part investigation of density. Make sure to check out...
American Chemical Society
Changing the Density of a Liquid - Adding Salt
Fourth in a set of several little lessons on density, this one compares the density of fresh and salt water. First by demonstration, and then by a hands-on activity, learners find that adding salt increases the density, as is evidenced...
Curated OER
Floating Oranges
Students get into groups or watch one demonstration of the game. They observe an orange floating in the pool, pretending it is a little boy/girl wearing a life jacket. Next, they watch as the orange is peeled and thrown back in, with the...

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...

Temperature Affects Density
Different substances can have different densities, but can the same substance have different densities? Lesson explores the effect of temperature on the density of water. Extension idea connects the concept of how melting ice in lakes...
Curated OER
Float Your Boat
Students investigate buoyancy, displacement and density. In this flotation lesson students study the Archimedes' Principle, analyze data and draw conclusions.
Curated OER
You Are What You Eat: Plastics and Marine Life
Students study the different types of plastics and see which ones sink or remain buoyant. For this ocean environmental lesson students complete several handouts, and view a film on PBS.
Curated OER
Density Studies of the Earth
Density comes to life as investigators place soda cans into containers of various liquids to find if they sink or float. They layer different density liquids, compare densities of different gases, and more. A total of six different...
Curated OER
Interactive Writing
First graders write about vehicles that float using the interactive writing procedure.
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.
Curated OER
Designing and Floating Boats
Middle schoolers participate in an experiment to determine if a toy boat will sink or float. They make the boats out of different materials and determine its carrying capacity by adding pennies. They graph their findings on a classroom...
Curated OER
Pumpkins, Pumpkins, Pumpkins
Students identify and interpret the lifecycle and parts of the pumpkin. Students utitlize interactive ways to discover this process. Students create a big book of their own by researching further information about pumpkins and what...

Gift for the Indians: Model of the Mayflower in the Ocean
Students build a miniature replica of the Mayflower. They make the boat float in a cup of water while studying the concept of gift giving on Feast Day.
Curated OER
i-Density Crisis
Eighth graders determine the density using mass and volume. For this science lesson, 8th graders explain why some materials float or sink. They estimate the density of objects based on whether it floats or sinks in a liquid of known...

Layers of the Earth
In this layer of the earth instructional activity, students label and color each layer of the earth. Then students are asked to describe each layer below.

Spring, Summer, Fall, Winter
In this seasons worksheet, students cut out the picture cards at the bottom of the page, sort the pictures and paste them with the matching season.
