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...

Students use the Scientific Method steps to complete an experiment on various brands of soap to determine their floating capabilities. In this scientific method lesson, students write a hypothesis about the ability of various soap bars...

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...

Learners must plan, design, and conduct an experiment that answers the scientific question: "Come up with a question that addresses the factors (variables) of the water and its effect on whether an object floats or sinks."

Students analyze density. In this density lesson, students experiment with floating an egg. Students discover that salt added to water changes the density of the water allowing an egg to float.

Students measure the properties of two different types of soap and wood and calculate their densities. Then they predict whether or not whether or not each object would float or sink in fresh or salt water.

Students listen to a PowerPoint presentation and complete a Venn diagram comparing the methods of transportation in the early 1800s with today's transportation. They experiment with the buoyancy of keelboats.

Students observe experiments in density and describe the results. In the experiment, milk, corn syrup, and oil are added in different orders to three glasses, while one other glass contains only water. As objects are dropped into each...

Students experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.

In this earth science worksheet, students read a poem about the wind and learn why the wind blows. After reading the poem and informative paragraphs that follow it, students answer 2 questions regarding the information they read....

Students draw upon their prior knowledge of the density of water and practice writing a hypothesis, making an observation, and analyzing data while watching a density demonstration.

In this elements, compounds, and mixtures learning exercise, students answer questions about the properties of elements, mixtures, and compounds. Students identify the physical changes that is made to a substance to determine if it is an...

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...

In this hot and cold water worksheet, students use hot and cold water to experiment and see what happens when the two mix together. Students also answer 7 questions.

Students define density in their own words. In this physics lesson plan, students calculate density using mass and volume. They explain why some objects sink and some float.

Students will make a lava lamp. In this density instructional activity, students will combine water and oil and make observations, then add salt to the oil and observe the oil sink, then float again when the salt dissolves in the water.

In this mass worksheet, students fill in a chart with different items and their volume, whether they float or sink, and their density. Students complete this for 10 items and answer 6 multiple choice mass questions.

Groups of young oceanographers get to use action figures to experiment with the property of buoyancy! This memorable lesson plan provides detailed background information, a link to the laboratory worksheet, and thorough instruction...

Although this is a science lesson, it can be adapted to help meet Common Core standards in math as well. Starting scientists describe physical properties of objects and explore three forms of water. To address the Common Core, they can...

Learners perform experiments to examine if debris float, or blow in the wind. The effects of these characteristics on the marine debris are then discussed. They determine how a material can influence what becomes marine debris.

Now is the time to educate tomorrow's citizens to care for the planet, and here is a instructional activity to help facilitate the process. Collect some marine debris and bring it into class. Have your class separate it into types and...

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...

Students identify the various states of water and its natural flow downward. As a class, students take digital pictures of different forms of water and create a multimedia presentation describing their photographs. Groups of students...
