Use the scientific method to experiment with an egg. Your class can examine buoyancy and density by finding how many spoons of salt are needed to float an egg. They can predict, experiment, record data, and analyze results.

Students will determine whether various objects sink or float in water. They do not need to explain why objects sink or float. They are rather to be encouraged to observe that the same objects will sink or float every time, i.e., that...

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...

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.

Young scholars predict and test different items to see if they sink or float. In this sink and float lesson plan, students predict whether an item is buoyant or not, and learn that size and weight do not matter when it comes to 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...

First graders drop items into water, and discuss why some things float and others sink.

In this buoyancy worksheet, students read about why objects float or sink. Students apply the Archimedes' Principle in a buoyancy lab. Students complete 1 graphic organizer.

First graders conduct an experiment. In this density lesson, 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.

It's all about density! Here's a dense workbook for young scientists; they solve (and show work for) 29 density word problems, including a problem where they solve for the density of Godzilla. They complete labs analyzing metal...

Learners conduct a science experiment to determine whether a variety of objects will sink or float. They discuss the concept of density, and then make predictions about whether the objects will sink or float. They then conduct the...

Students observe and classify objects that float or sink.

Students have seen that solids, which are more dense than a liquid, that sinks in that liquid and solids, which are less dense than a liquid, that floats on that liquid. They use a metal boat to float in water. Pupils comprehend that...

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!

Integrate science and literature by using the scientific method to test the veracity of the floating peach described in Roald Dahl's James and the Giant Peach. Clips from a Bill Nye: The Science Guy episode about buoyancy frontload...

Students explore the concepts of float and sink by playing a game where they build things on mud, water, rock and jelly. In this Anthony's sink or float game lesson, students discover what materials remain strong in various conditions....

For this mass worksheet, students fill in a chart with different items and their volume, whether they float or sink, and their density. Students complete this for 10 items and answer 6 multiple choice mass questions.

Special needs students explore why certain objects sink or float. They will make predictions on what objects will sink or float. Students conduct an experiment using a large bowl of water and several objects and test their predictions....

An engating lesson plan relates mass and volume to better understand density. Young scientists explore and experiment with floating and sinking as well as density cubes. Then, they solve how to make a sinking item float.

Playing with balloons, water, oil, and bottles help put this instructional activity over the top! Participants use air-filled balloons in water tanks to experience gas compression. They also use oil-filled bottles to experiment with...

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 use their background knowledge of how scientists work to discuss and predict if a given object will sink or float. They record their predictions on a data sheet. Students test the objects and organize them into floating or...

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...

Students conduct experiments in which they investigate which materials float and which sink. They examine what qualities the materials that float have in common. They carry out a scientific investigation, predict, and test their...
