Subject: Science (5)
Title: How does the USS Alabama Float?
Description: This is a science lesson on buoyancy and the USS Alabama. The students will discover how a battleship floats. They will complete hands on activities to better understand Archimedes' Principle of Buoyancy.

Subject: Science (5), or Technology Education (3 - 5)
Title: Volume
Description: Students will learn the concept of volume by determining the amount of sand that is needed to fill the long-jump pit at their school (or any rectangular- or square-shaped container). This lesson will explain the importance of knowing how to determine volume and how to use the concept in real-world situation.

Title: Who Sank the Boat?
Description: This lesson teaches the concept of measurement using grams and ounces through a student-created experiment. The students will get to test their own scientific predictions by constructing a boat and trying to sink it. This lesson provides students with an interactive way to learn about weight and buoyancy.

Title: Light, Dry and Nutritious - A Look at Dehydrated Food
Description: This is a hands-on, inquiry-based activity that involves study and exploration of dehydration and dehydrated foods. Students are actively involved in using math and science skills.

Title: Does Soap Float?
Description: In this lesson, from Science NetLinks, students form hypotheses and carry out an investigation in order to answer a central question: Does soap float? They then demonstrate their understanding of the topic through oral or written reports.

Title: Sink It
Description: This Science NetLinks lesson is designed to develop students' understanding of sinking and floating. Students first classify a group of common objects by a characteristic of their own choosing. Then they reclassify the same group of objects by their predictions about whether each item will float or sink in water. As a group, they design an experiment to test their predictions (hypotheses).

Title: Hot and Cold Colors
Description: The primary purpose of this Science NetLinks lesson is to engage students in an activity that allows them to observe that hotter conditions can speed up changes in materials. Students predict whether food coloring disperses more quickly in hot, cold, or room temperature water, then carry out a short activity to explore their predictions.

Subject: Science
Title: Color Burst
Description: In this Science NetLinks lesson, students gain experience in asking questions and conducting inquiries by exploring the separation of colors in water and other solvent. This lesson uses a technique called paper chromatography. This activity helps students gain experience in conducting simple investigations of their own while working in small groups.

Title: Buoyant Boats
Description: The purpose of this Science NetLinks lesson is to design and construct a boat that takes into account factors such as buoyancy, the properties of materials, and design constraints. In this lesson, students design and construct a boat out of aluminum foil and a few other simple materials. The boats are then tested by floating them in a pool or sink and by adding mass until they sink. While students may not be able to articulate it, they intuitively begin to understand the scientific laws required for the design of the boat, including buoyancy and Archimedes Principle. They also explore shapes of boats and construction techniques that may work for the boats.

Determining Density via Water Displacement
http://www.explorele...
This website allows students to interact to determine the density of objects based on the amount of displaced water using Archimedes' principle by dropping objects in a beaker that is filled with water and measure the water that flows over the edge. Requires flashplayer.

Density
Why do objects like wood float in water? Does it depend on size? Create a custom object to explore the effects of mass and volume on density. Can you discover the relationship? Use the scale to measure the mass of an object, then hold the object under water to measure its volume. Can you identify all the mystery objects?

The Magic Ketchup Experiment
http://www.sciencebo...
The is an amazing, quick, and inexpensive experiment about buoyancy and density where pressure is used to make the packet of ketchup more dense than the water around it. It also has "Make it an Experiment" questions at the end.
