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...

Let's go sailing! An instructive unit includes six lessons with multiple activities to teach scholars about density, center of gravity, buoyancy, and the Archimedes Principle. They can complete the final project of building a boat...

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

First graders discuss why some things sink and some float after dropping a variety of items into water.

Discuss Archimedes' Principle and fluid forces with your young scientists as they describe the relationship between mass, volume, and density during a series of engaging activities. They use the Participle Theory of Matter to explore the...

Enhance your states of matter lessons with a hands-on science investigation that compares six different balls' color, texture, size, weight, ability to bounce, and buoyancy. 

Third graders recognize that different materials have different properties which can be observed such as texture and bouyancy, and compare and contrast, through observation, ability of some objects to float because of action of...

Third graders conduct an experiment. In this floating and sinking liquids lesson, 3rd graders discuss density and investigate it using syrup, vegetable oil and colored water. Students observe the results and complete a worksheet.

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

Investigators construct a makeshift balance and compare equal volumes of wax and water. They do the same for clay and water. Then they discover whether the wax and clay will float or sink in water. Ultimately this is a comparison of...

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...

Ninth graders predict when an object will sink or float based on comparison of the density of the object to the density of the substance in which it is placed.

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...

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...

Students explore the concept of density by trying to make a penny and other materials float.

In 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 a...

Students design a simple boat and predict how much weight it can carry. They should also discover why objects float or sink and how this can be determined experimentally. A great lesson on buoyancy!

In this buoyancy worksheet, students read about the principles behind objects floating including density, buoyancy and Archimedes' Principle. Students complete a buoyancy lab where they use a balloon and water and a film canister and...

Young scholars explore the changing density of water. For this physics lesson, students investigate how an object's density determines whether it will float or sink in water. They explain why this unique property of is important to...

Students discover fluid dynamics related to buoyancy through experimentation and optional photography. Using one set of fluids, they make light fluids rise through denser fluids. Using another set, they make dense fluids sink through a...

Third graders graph how much water is wasted while waiting for it to get warm in the spigot in the sink. In this graphing lesson plan, student first predict how much water is wasted. That night they test it out at home and the next day...

For this science instructional activity, 6th graders take a multiple choice quiz about properties, energy, formulas, and more. Students complete 30 questions total.

First graders write with his or her pencil on a worksheet created by the teacher his or her prediction of whether each part of a pumpkin will sink or float. They drop each of five objects in the water one at a time allowing enough time...
