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.

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...

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.

Keep your class afloat with a hands-on density lesson plan. The challenging lesson plan has learners experiment with different materials to compare their densities. They learn that increasing or decreasing the amount of the material...

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.

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...

Students construct clay boats and predict whether the boats will sink or float. Students will hypothesize what caused the boats to sink or float.

Students analyze the relationship between density, buoyancy, and salinity. In this chemical properties lesson, students read a background activity for the lesson and experiments to the topics. Students discuss the questions and complete...

Use the scientific method to experiment with an egg. Your class can examine buoyancy and density by finding how many spoons of salt are needed to float an egg. They can predict, experiment, record data, and analyze results.

Learners explore how density can cause things to sink or float by experimenting with a jar, oil and corn syrup.

Learners conduct an experiment. In this water lesson, students watch the lesson "Float and Sink" on an interactive website. Learners learn how to test items in water and then work in groups to test their items. Students discuss their...

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...

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.

Young scholars describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas,...

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...

Students experiment to find which liquids are more dense.  In this density and mass lesson, students predict and then test objects to observe and measure their density. students observe which items sink and float. Students complete...

Students use descriptive vocabulary to discuss the attributes of matter. Then, they sort objects or pictures by the type of matter they are comprised of. Finally, students match objects of matter with similar attributes and create a...

Students observe teacher demonstrations that illustrate density. In this density lesson, the teacher demonstrates how air bubbles in a carbonated drink can cause a raisin to float and how an egg sinks in fresh water, but floats in salt...

Third graders recognize that different materials have different properties which can be observed such as texture and bouyancy, and compare and contrast, through observation, ability of some objects to float because of action of...

Investigators construct a makeshift balance and compare equal volumes of wax and water. They do the same for clay and water. Then they discover whether the wax and clay will float or sink in water. Ultimately this is a comparison of...

Why do some things float and others sink? A creative simulation allows learners to adjust mass and volume of an object to affect its buoyancy in water. A graph records the effect of each manipulation.

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.

Students discover density.  In this density lesson, students discover the properties of objects that allow them to float or sink in water.

Students explore the density of soap. In this science lesson, students conduct an experiment to find which types of soap will float. Students make a hypothesis and record their observations.
