Students investigate buoyancy. In this buoyancy lesson, students apply the Archimedes Principle of Buoyancy to the experiment conducted in class to determine how battleships float.

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.

Students investigate the concept of density by observing demonstrations. In this density lesson plan, students make observations while the teacher demonstrates the Cartesian diver, a density column, a candle trough, a wave bottle, an...

Tenth graders experiment with floating and sinking objects and heavy and light liquids, using correct terms, like density, to explain what happens.  In this Hindenburg instructional activity, 10th graders watch a demonstration...

Sixth graders investigate the properties of water. In this life science lesson, 6th graders create a concept map of water. They share their work with the class.

Students investigate surface tension and bubbles. For this scientific inquiry lesson plan, students explore how the surface tension of water is able to support tiny objects that actually weigh more than the water as they collect date by...

Why does a seastar sink, but a jellyfish float? Through a fun investigation, learners examine the concept of buoyancy using simple household items. The challenge: create neutral buoyancy for an action figure in water. With ample...

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...

Study how plants grow with your English language learners with a cross-curricular lesson plan revolving around pumpkins. These activities provide opportunities to practice new scientific vocabulary while practicing skills such as...

Here is a nice lesson, which includes some good worksheets, on pumpkins and how they grow. It is an ESL lesson designed for beginning and early intermediate students. After listening to some books about pumpkins, learners label pumpkin...

Students calculate the densities of several liquids that appear similar.  In this physical science lesson, students go beyond understanding the way liquids of different densities behave to researching how this knowledge applies in...

High schoolers determine the linear equations of the density of water and oil by collecting data on the mass of various volumes of each liquid. They construct scatter plots from the data and use these to write the linear equations for...

Students participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.

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...

Sixth graders develop an understanding of floating, sinking, density, and buoyancy and apply it to the design of testing of ships.

First graders study ways in which the earth changes due to erosion and weathering in this series of lessons.

Students investigate the density of liquids. In this geometry lesson, students calculate the volume and differentiate between volume, mass and density. They observe similarity and differences between coke and diet coke.

Fourth graders, in groups, experiment with density and the displacement of water by creating and designing their own boats and seeing which boat holds the most centimeter cubes without sinking..

Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.

Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

Learners examine the flow of water. They observe and test the properties of water by using sticks in flowing water. The lesson plan has streaming video, resource links to access, and a good hands-on activity that is clearly described in...

Students experiment with water density, temperature and salinity. In this water lesson, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.

Fourth graders explore and experiment with objects that float to see if they float differently in salt water or fresh water. After the experiment, they write a paragraph in their science journal explaining how fresh water and ocean water...

Young scholars explore rotating frames of reference, focusing on the weightless environment in space and the Coriolis force.
