Students explore the concept of density. In this density lesson plan, students determine the density of various objects. Students use the density of the various objects to predict the density of various unknown solutions.

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

Ninth graders develop operational definition of density, do computations using density equation, categorize pieces of matter as being able to float on water or not, based on density, explain why some objects sink or float based on...

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...

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...

Second graders discuss why some objects float while others sink. They examine various objects and predict whether or not they will sink or float. Students discover the properties needed for objects to float.

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

Students write and explain why an object sinks or floats.  In this buoyancy lesson students demonstrate how items float or sink and graph the results. 

Students participate in an experiment to determine which objects float or sink. They use different amounts of salt for the objects and discover as the salt content increases, objects will float. They record their predictions and what...

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.

Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.

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 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 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 conduct an experiment.  In this marine debris and environment protection instructional activity, students categorize trash into piles, predict whether these trash items will sink, float or be picked up and carried by the...

Students explore water properties by conducting a class experiment. In this buoyancy lesson, students make predictions as to whether or not specific objects will sink or float in water. Students conduct the experiment and record their...

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

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...

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...

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...

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...
