An engating lesson plan relates mass and volume to better understand density. Young scientists explore and experiment with floating and sinking as well as density cubes. Then, they solve how to make a sinking item float.

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...

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,...

The difference between sinking and floating may be a little salt. Young experimenters analyze the effect of salt and temperature on the density of water. They use their results to predict the effect of climate change on ocean ecosystems.

Students predict whether objects will sink or float in water. They classify objects as sinking or floating in water. Students identify and explain similarities between objects that sink and float.

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.

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...

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...

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...

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...

Students explore physical science by conducting an in-class experiment. In this density lesson, students define vocabulary terms dealing with physics and discuss their knowledge of density. Students conduct several "sink or float"...

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.

Some of these beautiful diagrams should help your students understand the connections between pressure and flight. Pressure and density are also discussed, and a number of links are included to give fantastic interactive examples of...

First graders drop items into water, and discuss why some things float and others sink.

Students observe and classify objects that float or sink.

During a unit on density, pupils ponder whether or not temperature affects this property. By carefully inserting blue cold water and yellow hot water into a room-temperature sample, they will see the answer. Make sure to have done the...

Discuss Archimedes' Principle and fluid forces with your young scientists as they describe the relationship between mass, volume, and density during a series of engaging activities. They use the Participle Theory of Matter to explore the...

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...

Fourth graders examine pumpkins and use the scientific method to explore its contents.  In this Pumpkin Science lesson, 4th graders measure pumpkins for circumference. Students dress as if they were in a lab and work in pairs to...

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.

Explore the concept of density within states of matter—gases, liquids, and solids—through a group experiment in which young scientists test objects' texture, color, weight, size, and ability to sink or float.    

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...
