Will it sink or will it float? Learners predict the outcome as they drop random objects into a container of water. Then, they keep track of the results and record the data in a t-chart to draw a final conclusion.

Explore the concept of density within states of matter—gases, liquids, and solids—through a group experiment in which young scientists test objects' texture, color, weight, size, and ability to sink or float.    

There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...

Why do some things float and others sink? A creative simulation allows learners to adjust mass and volume of an object to affect its buoyancy in water. A graph records the effect of each manipulation.

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. 

Use STEM activities within the class to provide connections to concepts. The resource includes activities that range from working with buoyancy to building rockets and launching them. Other activities involve the engineering design...

Make a splash with young scientists as you teach them all about water using this activity packet. Thirstin, a cartoon glass of water, walks children through the water treatment process, teaches them about different sources of water, and...

Students determine whether a liquid will sink or float in water by comparing its density to the density of water.

Learners determine whether an object will sink or float by comparing its density to the density of water.

This is an educator's guide for a unit on things that sink or float. It includes lesson plans, experiments, and activities. Students apply the scientific method as they investigate whether objects sink or float.

In this activity, students will learn about density by determining how to make an egg float in water. By the end of the lesson plan, students will understand that density and weight are different and that density matters in floatation....

Throughout the activities in this investigation, students may have wondered how a boat made out of steel, which is more dense than water, can float. This activity addresses that question. Students will see that changing the shape of an...

By the end of this section, you will be able to define buoyant force, state Archimedes' principle, understand why objects float or sink, and understand the relationship between density and Archimedes' principle.

Help the Sesame Street characters while completing various early learning tasks. Students will develop language, reasoning skills, and independence as they play the games provided.

A collection of interactives, videos, and documents on a variety science concepts.

[Free Registration/Login Required] Students will be able to change the mass and volume of an item and observe if it floats, sinks, or remains at a certain depth in the water. Students will also be able to change the liquid in level 2.

Experiment with a helium balloon, a hot air balloon, or a rigid sphere filled with different gases. Discover what makes some balloons float and others sink.
