Second graders identify three forms of matter- solids, liquids, and gases with 100% accuracy. They observe water evaporating from an open container and water evaporating and condensing in a closed container. The students assess that a...

Second graders discover what changes occur in various types of matter under different conditions. They make predictions about the changes in an apple left out in the air, water placed in a freezer, and a nail left in a cup of water. They...

Students use plastic bottles, water, and condiment packets to simulate how natural gas comes from decaying ocean plants and animals. In this natural gas lesson plan, students also fill out lab packets and answer exit questions.

Students explore whales. In this animal adaptation and whale lesson, students access prior knowledge about whales from previous lessons, then use background knowledge to predict the eating strategies of a baleen whale and a toothed...

An interactive simulation that teaches about buoyancy and density by applying various forces and modifying the properties of objects and fluids. This simulation can either be downloaded or played online and includes handouts, lesson...

As part of a larger resource called "Getting started in Chemistry," this page examines various topics related to density and buoyancy. Included in the study are definition of density and buoyancy, measurements, applications, and examples.

Students studying buoyancy will better understand its concepts with this virtual experiment using various balloons and testing what makes them float or sink.

Sure you understand what makes submarines cool, they allow us go underwater and explore the sea! But understanding how they function is a completely different matter. This lab will help you investigate how submarines dive and surface by...

This is an inquiry-based activity in which students will need to work together as a class to solve the following problem: they must construct a "boat" entirely out of modeling clay that is capable of supporting 150 grams of cargo without...

Adjust the ratio of the masses of different particles to see how buoyancy is affected.

Description of buoyancy and a definition of Archimedes' Principle. Problems are presented and solved using Archimedes' Principle.

This lab was designed to have students test the relationships that affect the force buoyancy. Not all things they change will be factors. They can change mass of bottle, volume of bottle, fluid type and planet.

This interactive brainteaser from the NOVA: "Voyage of Doom" Web site challenges you to figure out what causes an object to sink.

In the following lesson for grades 6-8, learners learn about environments with gravity and those with reduced gravity by observing the behavior of a water-filled plastic bag, both inside and outside of a container of water.

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.

Students explore material properties in hands-on and visually evident ways via the Archimedes' principle. First, they design and conduct an experiment to calculate densities of various materials and present their findings to the class....

Young scholars learn that buoyancy is responsible for making boats, hot air balloons and weather balloons float. They calculate whether or not a boat or balloon will float, and calculate the volume needed to make a balloon or boat of a...

Students explore buoyancy. Some topics examined in the activities are buoyant force, stability of floating objects, and Archimedes' principle. The resource consists of video clips, lecture notes, practice problems, and exam questions....

Ever wonder why/how things float? This concept is called buoyancy. Take this interactive journey to learn and understand how and why certain materials float and others sink to the ocean floor.

In this science fair project, measure the "lift" of a set of balloons and track how it changes over time as the helium escapes from the balloons. The Science Buddies project ideas are set up consistently beginning with an abstract,...

A lesson and activity sheet on buoyancy. Students add weight to a helium-filled balloon to keep it suspended so that it won't float or sink, but instead will 'flink.'

Students must figure out the number of people that can go on a raft without having the raft go fully under the fluid.

In this lab, learners will use the scientific method to design an experiment that explains how/why a submarine floats and sinks.
