Students watch the teacher do a demonstration of density with diet and regular soda. Note: try this first, as different types of artificial sweetener have different densities. Students discuss density and volume. They discuss "Relational...

Middle schoolers explore the relationship between density and buoyancy. After watching a video explaining buoyancy, students discuss displacement and floating. Middle schoolers have a raft building competition. Afterward, they conduct...

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...

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...

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.

Students explore density by floating golf balls. They explore having their golf balls float halfway in a container of water and discuss density and its realtionship to where the golf balls are floating. After adding food coloring, they...

Let's go sailing! An instructive unit includes six lessons with multiple activities to teach scholars about density, center of gravity, buoyancy, and the Archimedes Principle. They can complete the final project of building a boat...

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 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"...

Young scholars explore animal and plant adaptation.  In this ecosystems science lesson, students view websites to gain information about plankton and its  interdependence within ecosystems. Young scholars identify ways in which...

Students investigate ways to find the density of irregular shaped objects. For this physics lesson, students calculate density using its mass and volume. They explain why some objects float or sink in water.

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...

Why does a seastar sink, but a jellyfish float? Through a fun investigation, learners examine the concept of buoyancy using simple household items. The challenge: create neutral buoyancy for an action figure in water. With ample...

Second graders watch a demonstration and complete an experiment to determine how an objects' density allows it to float or sink. They work in small groups to assimilate the characteristics of items that float as opposed to simply...

Students observe earth science by examining results from an experiment. In this buoyancy instructional activity, students practice floating different items in two different liquids and identify why certain objects will float and others...

Students will make a lava lamp. In this density instructional activity, students will combine water and oil and make observations, then add salt to the oil and observe the oil sink, then float again when the salt dissolves in the water.

Students explore the states of matter. In this physical science lesson, students observe what happens to water when it freezes and record observations. Students then observe ice when it melts and record observations.

Students study the ocean and its characteristics.  In this oceans lesson students complete a lab activity and are able to predict temperature of certain depths. 

Sixth graders develop an understanding of floating, sinking, density, and buoyancy and apply it to the design of testing of ships.

Sixth graders investigate the properties of water. In this life science lesson, 6th graders create a concept map of water. They share their work with the class.

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

Middle schoolers are introduced to the concept of buoyancy. The Video used in this lesson demonstrates and explains the characteristics of objects that sink and float. It presents the concepts of displacement, weight, and buoyancy.

Students inspect nutrition by conducting a science experiment in class. In this vegetable identification lesson, students examine a group of different veggies and predict whether they will sink or float in a tub of water. Students check...
