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...

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...

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.

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.

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...

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 consider density and how it affects sinking and floating. Students make predictions, test liquids, and observe why some liquids sink and others float. They perform experiments to determine relational causality and how liquids...

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

This particular lesson plan was written by the National Earth Science Teachers Association, but density is a concept that you can teach at the beginning of the school year in your life, physical, or earth science classes. It would be fun...

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...

Students explore the characteristics of water. In this water exploration lesson, students participate in various learning centers to inquire how water drains and how to increase the flow of water. Students use estimation and measurement...

Sometimes the simplest experiments leave the biggest impression! Introduce young chemists to the Cartesian Diver by having them make one of their own. Use the Diver to further their study of liquids and gases, as well as compression.

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...

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...

What do we do when a dive is too dangerous for humans to accomplish? Send in the robots! Middle school scientists get acquainted with several different models of submersible robots in the second lesson of six from NOAA. Lab groups then...

Third graders conduct an experiment. In this floating and sinking liquids lesson, 3rd graders discuss density and investigate it using syrup, vegetable oil and colored water. Students observe the results and complete a worksheet.

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.

Students examine whether objects will sink or float.  In this buoyancy lesson students bring in objects and experiment to see if they sink or float.

Students use the Scientific Method steps to complete an experiment on various brands of soap to determine their floating capabilities. In this scientific method lesson, students write a hypothesis about the ability of various soap bars...

Enhance your states of matter lessons with a hands-on science investigation that compares six different balls' color, texture, size, weight, ability to bounce, and buoyancy. 

Eureka! Using the clay boats made in the previous lesson, learners investigate the idea of buoyancy and water displacement to finish the last installment of five in a Floaters and Sinkers unit. Their observations during the activity...

Learners must plan, design, and conduct an experiment that answers the scientific question: "Come up with a question that addresses the factors (variables) of the water and its effect on whether an object floats or sinks."

Students measure the properties of two different types of soap and wood and calculate their densities. Then they predict whether or not whether or not each object would float or sink in fresh or salt water.
