Steal cubes sink, but steal ships float. Lesson explores the density of solids as well as the density of water in determining what will sink and what will float. A hands-on group activity helps pupils see that weight and volume are...

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...

Integrate science and literature by using the scientific method to test the veracity of the floating peach described in Roald Dahl's James and the Giant Peach. Clips from a Bill Nye: The Science Guy episode about buoyancy frontload...

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...

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.

Students predict and test different items to see if they sink or float. In this sink and float lesson plan, students predict whether an item is buoyant or not, and learn that size and weight do not matter when it comes to buoyancy.

We don't think of liquids as floating typically, but a quick look at any oil spill tells a different story. Lesson explores various densities of liquids and why this fact is important. After observing the density variation, scholars...

Learners conduct a science experiment to determine whether a variety of objects will sink or float. They discuss the concept of density, and then make predictions about whether the objects will sink or float. They then conduct the...

Have your class predict whether objects will sink or float in water. Learners consider a data table of mass, volume and whether the object sank or floated. They develop an evidence-based explanation for the results.

Introduce your class to the concept of sinking and floating. In groups, they classify objects after making predictions about which materials will sink or float. They record their results and create graphs and charts to share with the class.

Students recognize that density determines whether objects sink or float.  In this sink or float lesson, students experiment with plastic in three liquids. students drop their objects into the liquids and observe and record their...

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

Second graders explore floating and sinking and make predictions about whether certain objects are likely to sink or float. They read the story Who Sank the Boat? by Pamela Allen. Pupils loacate rhyming words and discuss the events of...

Young scholars explore sinking and floating.  In this buoyancy instructional activity, students conduct an investigation dealing with regular and diet soda. Young scholars drop various soda cans into water and then discuss why...

Want to get your students motivated in science class? Given only a piece of aluminum foil, assign groups the task of designing a "barge" that will support the weight of a bunch of pennies.  The group who is able to put the most...

Where does all of the carbon dioxide come from that is supposedly leading to climate change? Earth science pupils test animal, plant, and fossil fuels as sources in this investigation. Using an indicator, BTB, they are able to detect the...

First graders discuss and predict if a given object sinks or floats. They record their predictions on a data sheet. Pupils test the objects and organize them into floating/sinking groups. Students observe the floating and sinking of a...

Is your current lesson plan for salt and freshwater literacy leaving you high and dry? If so, dive into part one of a seven-part series that explores the physical features of Earth's salt and freshwater sources. Junior hydrologists...

Cut milk cartons in half to make boats and let investigators attempt to sink them. They add dividing walls and observe what happens if marbles are put into only one of the newly formed compartments. Vocabulary is provided: buoyant force,...

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 experiment with different objects to see if they sink or float. They can also choose certain colored items if more review is necessary.

First graders work in cooperative groups and utilize a variety of materials to test objects ability to sink or float. For this sink or float lesson, 1st graders discover why some object sink and others float. Students will graph results...
