Sink or Float

Our Sink and Float lesson plan teaches students the basics of why objects sink or float based on their density. Students practice predicting whether an object will sink or float and will be able to speak about density.

Our Sink or Float lesson plan introduces students to the concept of sinking and floating relative to an object’s density. During this lesson, students are asked to work with a partner to complete an activity in which they predict whether a given object will float or sink, put the object into water, and then record whether they were correct or not; they are then asked to draw the object and answer questions about their hypotheses. Students are also asked to tell whether each statement about sinking or floating is True or False.

At the end of the lesson, students will be able to define and distinguish the difference between sinking and floating, and predict and identify objects that will sink or float, and explain why.

    Excellent Free Resource

    I was truly impressed with the quality of the lesson that was free of charge. It was such a professional presentation. This lesson truly saved me so much time. I have not presented the lesson yet however, I am sure the students will be engaged in such an inviting hand-on approach to teaching the concept of buoyancy. I appreciate having access to such quality materials without an additional charge. Keep up the great work. Teachers definitely need the support that this organization provides.

    Great Materials

    I am going to be teaching 3rd grade Math and Science this fall and these materials are a great starting point. Thank you for making them available.

    Great lesson

    We used the density lesson with my 2 year old. He loved doing the experiment.

    Great and easy to use

    My son and I read the materials on the computer screen and I just printed out the worksheet he would write on. I liked it because it made him practice his handwriting (which he hates) without him even realizing it!
