A video and laboratory investigation are highlights to this lesson on acidification of ocean water due to increased atmospheric carbon dioxide. Using bromothymol blue (BTB) as an indicator, pupils analyze the amount of carbon dioxide...

Students explore the states of matter. In this physical science lesson, students observe what happens to water when it freezes and record observations. Students then observe ice when it melts and record observations.

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 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 test...

Students create a model boat. In this art lesson, students identify what makes a boat float and use milk cartons to create their own boat.

Clay's as good a material as any to build a boat, right? An introductory lesson plan sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats to measure...

Students perform experiments to see if items will sink or float. In this sink or float lesson, students work in groups to make predictions, and record the results. After the experiments are complete students make a book of the results.

Students investigate the states of matter. In this physics lesson, students use water and ice to demonstrate the characteristics of a solid and liquid. Students record their observations as the state of the water changes.

Students examine how salt water is more dense than fresh water through experimentation with eggs.

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...

Students examine how weight and balance can effect if an item sinks or floats. They listen to the book "Who Sank the Boat?" by Pamela Allen, and discuss how the smallest animal sank the boat. Students then conduct an experiment in...

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

Combine science and literature with this activity on buoyancy. Read There's an Ant in Anthony by Bernard Most to examine words containing the letters a, n, and t. Then introduce your class to the word "buoyant." Demonstrate how an...

Flotsam by David Wiesner and The Magic School Bus on the Ocean Floor by Joanna Cole, illustrated by Bruce Degen, begin a reading adventure pack focusing on oceans. With story listening and thoughtful discussion, scholars complete several...

Students examine why some objects float while others do not. They place various objects in water to observe their floating capability. Students record the object, its weight, and if the object floated. They construct a graph plotting...

First graders explore items that sink or float. They cut and glue pictures of objects that they predict will sink or float. Students place thir pictures on a picture of a bucket of water. Students then color the objects that they had...

Junior high schoolers explore possible theories for the cause of the Hunley submarine sinking. Through hands on activities, they investigate how to create a waterproof seal. Afterwards, they discuss how seals work and various...

Students experiment with different objects to test if they sink or float. They predict what the object will do before it is put into the water. They are allowed to play with the items after the experiment is over.

Students participate in an experiment about the weight of water. They work together to discover that seawater is more dense than fresh water. They also determine which objects float and sink.

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...

There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...

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 lesson, 10th graders watch a demonstration called the invisible...

Students form hypotheses and carry out an investigation in order to answer a central question: Does soap float? The focus of this lesson is on scientific inquiry, but it incorporates scientific topics such as sinking and floating.

Third graders sort objects into those they think will float and those that will sink and test their predictions. They experiment with clay molding it into shapes that float. They place pennies in them until they sink. They test other...
