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...

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...

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.

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.

Earth or environmental science pupils are assigned to be carbon sources or sinks. They ask yes-or-no questions to try to figure out which one they are. Then they discuss ways people can have positive effects on the changing climate by...

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.

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.

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.

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.

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...

We're not talking about the kitchen sink. Learners explore what types of objects sink and float in water in an inquiry-based lesson. With experimentation, they find similarities between materials that float and those that sink.

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

Special needs students explore why certain objects sink or float. They will make predictions on what objects will sink or float. Students conduct an experiment using a large bowl of water and several objects and test their predictions....

Investigate the sinking of the Titanic with young scholars. They will read actual documentation from the Titanic and answer questions. They will then draw conclusions from the pictures they see and information they read.

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...

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

Students explore sinking and floating.  In this buoyancy lesson, students conduct an investigation dealing with regular and diet soda. Students drop various soda cans into water and then discuss why some float and some sink. 

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...

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...

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...

Keep your class afloat with a hands-on density lesson. The challenging lesson has learners experiment with different materials to compare their densities. They learn that increasing or decreasing the amount of the material doesn't change...

First graders conduct an experiment. In this density lesson, 1st graders work in groups to test 10 different objects to see which ones sink and float. Students discuss why certain objects float and others do not.
