Students conduct an experiment.  In this marine debris and environment protection instructional activity, students categorize trash into piles, predict whether these trash items will sink, float or be picked up and carried by the...

Students discover fluid dynamics related to buoyancy through experimentation and optional photography. Using one set of fluids, they make light fluids rise through denser fluids. Using another set, they make dense fluids sink through a...

Third graders graph how much water is wasted while waiting for it to get warm in the spigot in the sink. In this graphing lesson plan, student first predict how much water is wasted. That night they test it out at home and the next day...

For this science instructional activity, 6th graders take a multiple choice quiz about properties, energy, formulas, and more. Students complete 30 questions total.

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...

This is a brief survey of the states and properties of matter directed toward upper elementary physical scientists. Solids and liquids are compared. Density and buoyancy are related. Use this presentation just prior to demonstrating...

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...

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.

Students explore the concept of buoyancy through experimentation. Given materials of various weights and composition, they drop them in club soda and determine which substances sink or float. Students discuss their results in terms of...

Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.

This open-ended boat building exercise is meant to be part of a three-lesson series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat, find its load line...

Students observe and experiment with the concept of density. This is done using a simple experiment that helps them to apply scientific principles of observation and proving a hypothesis.

Students participate in an experiment to determine if a toy boat will sink or float. They make the boats out of different materials and determine its carrying capacity by adding pennies. They graph their findings on a classroom graph.

What did the sea say to the boat? Nothing, it just waved. An inquiry-based lesson starts with a simple concept on the Archimedes Principle and challenges pupils to make something out of clay that floats. Then, they design...

Fourth in a set of several little lessons on density, this one compares the density of fresh and salt water. First by demonstration, and then by a hands-on activity, learners find that adding salt increases the density, as is evidenced...

During a unit on density, pupils ponder whether or not temperature affects this property. By carefully inserting blue cold water and yellow hot water into a room-temperature sample, they will see the answer. Make sure to have done the...

How many pennies can an aluminum foil boat hold? That is the challenge in a collaborative activity designed to explore the concept of buoyancy. Learners use aluminum foil to build makeshift boats and test the weight they hold before...

Students examine how salt water is more dense than fresh water. They discuss how manatees need to float and sink, conduct a sink or float experiment, and conduct an experiment with eggs and salt and fresh water.

Begin with an introduction to famous deep-sea submersibles. Learners work in groups to gather information on different vessels and then share with the class. Each group then uses water displacement to help calculate the density of...

First graders discuss with the teacher if everything will float in water. They observe a marble and determine whether it will float making predictions as a class. After observing the results, they discover that liquids exert an upward...

Students discover density.  In this density lesson, students discover the properties of objects that allow them to float or sink in water.

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

Students explore the density of soap. In this science instructional activity, students conduct an experiment to find which types of soap will float. Students make a hypothesis and record their observations.

Students observe teacher demonstrations that illustrate density. In this density instructional activity, the teacher demonstrates how air bubbles in a carbonated drink can cause a raisin to float and how an egg sinks in fresh water, but...
