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 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...

Students experiment with objects of different densities. In this density lesson, students examine same-sized objects with different weights, then look at a teacher explanation of density. Students make wave bottles and a density jar to...

First graders examine the water cycle through readings and experiments. In groups, they conduct interviews with others and use the information to create a chart displaying the various uses of water. After brainstorming lists of ways to...

Students discover how seeds travel from their parent plants in search of water, sunlight, and nutrients, and conduct experiments in which they note characteristics that encourage seed dispersal by means of wind, water, animal carriers,...

Enhance your states of matter lessons with a hands-on science investigation that compares six different balls' color, texture, size, weight, ability to bounce, and buoyancy. 

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

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

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.

Young scholars perform simple and fun experiments to use the scientific method, take careful notes, and write a lab report. They first make and test a hypothesis about how many drops of water they can fit on the face of a penny and then...

Learners construct their own submarine following a certain procedure. In this physics lesson, students calculate the density of objects using a mathematical formula. They explain why some object floats in water while some do not.

Learners design and construct a boat out of aluminum foil and a few other simple materials. The boats then be tested by floating them in water, then adding mass until they sink. They explore the various shapes of boat construction.

Students participate in a hands on activity simulating an oil spill. In this oil spill lesson plan, students conduct an experiment about an oil spill, discuss how it would affect the environment and provide solutions to prevent oil spills.

Students experiment observing a demonstration on models of density-driven currents which are typically found in an estuarine system of water flow. They compare/contrast water temperature and salinity to the formations of estuarine currents.

In this plastics worksheet, students experiment with an unknown plastic and determine the polymer name and resin code by using a flow chart of various tests. They answer five questions after they collect their data.

Students investigate why some objects float or sink in water. In this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.

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 listen to the book "Mr. Betts and Mr. Potts" and examine the career of being a veterinarian. They categorize animals based on whether they could be house pets or not, develop a class pet graph, and list the various...

How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...

Present the class with a question on whether the water level of a pond will rise they take a large rock out of a boat and drop it into the pond. Groups come down on all sides of the question and try to justify their answers. The activity...

In this density worksheet, students complete a science lab experiment to determine the density that an object will float or sink in water. Students fill in a chart with their data, answer 4 short answer questions and write 1 conclusion...

Students 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 use hands on scientific observation to determine characteristics of wood. They work directly with the materials and record their observations. Students test if wood absorbs water, if wood floats or sinks, and if all wood...

Students explain that some things can float on top of water because of what we call "surface tension." They see that if something happens to disturb these water molecules from tugging on each other, the skin-like surface breaks up.
