Learners investigate which objects sink and which ones float. Learners engage in an experiment, make predictions, and record results on a graphic organizer. This is a comprehensive and easy to follow resource.

Have your class explore density and buoyancy using this resource. Learners read the book Who Sank the Boat, and use several items, such as rubber balls, bottle caps, wood, and other household items to conduct an experiment. Using a tub...

Students investigate whether different objects sink or float in water using the Scientific Method. They listen to the book "Christopher Columbus" by Stephen Krensky, identify the steps of the Scientific Method, conduct the sink or float...

Using a variety of objects, learners conduct buoyancy experiments. They make predictions on which object will sink or float and test their predictions. They use a graphic organizer to record their findings.

Students make and test predictions about sinking and floating, and classify objects according to whether they sink or float.

Students will determine whether various objects sink or float in water. They do not need to explain why objects sink or float. They are rather to be encouraged to observe that the same objects will sink or float every time, i.e., that...

Investigate which items float and which ones sink using this resource.  Learners participate in an activity in which they investigate this phenomena. Then they describe the experimental process, and learn how to display their results.

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

Students observe and classify objects that float or sink.

In this early physics activity, learners cut out pictures of 16 everyday objects. Students determine whether each of the objects will float or sink and then paste the pictures in the appropriate boxes.

In this early physics activity, learners respond to 4 short answer questions regarding a "float and sink" experiment they conducted.

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.

Don't just sink the boat. Using a closed container as a submarine, pupils experiment to see what to add to the container to make it float, sink to the bottom, and hover in the middle. After finding one option, learners see if they can...

Students explore the concepts of float and sink by playing a game where they build things on mud, water, rock and jelly. In this Anthony's sink or float game lesson, students discover what materials remain strong in various conditions....

Make a splash with young scientists as you teach them all about water using this activity packet. Thirstin, a cartoon glass of water, walks children through the water treatment process, teaches them about different sources of water, and...

Pupils use their background knowledge of how scientists work to discuss and predict if a given object will sink or float. They record their predictions on a data sheet. Students test the objects and organize them into floating or...

Students examine whether objects will sink or float.  In this buoyancy lesson students bring in objects and experiment to see if they sink or float.

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 predict and explore to discover which objects sink or float in fresh and salt water, predict how salt affect objects, write predictions on T chart, discuss difference between man-made and natural waters, and graph results.

Learners examine the flow of water. They observe and test the properties of water by using sticks in flowing water. The lesson plan has streaming video, resource links to access, and a good hands-on activity that is clearly described in...

Match animals to their environments with a cute lab activity. Kids draw a line between each animal, such as a fish, a rabbit, and an ant, to the place where it lives. For hands-on practice, a science investigation instructs learners to...
