Build an aluminium foil barge that can hold the most pennies, experiment with what floats and sinks and why, explore the relationship between density and buoyancy, and more! My lessons are geared toward 4th-5th grade level children and their siblings. These are lessons I created to do with a weekly homeschool co-op.

Say something such as:<\/li>\n<\/ol>\n<ul>\n<li>Some things sink and some things float. We can look at something and know from its weight, size, and so forth whether or not it will float or sink. What if I put this rock in this water? Would it float or sink? (Drop it in.) What about if it didn&#8217;t sink? What would we call that? (A miracle.) When something happens that is contrary to all the rules of science, we call it a&#8230;<\/li>\n<p><\/p>\n<li>-Is it possible for you or for me to walk on water? This true event lets us know that Jesus really was God. He could do things that are impossible for people to do, such as walking on the water.

Ducks and geese float for a similar reason. Their feathers contain tiny tubes filled with air. Sometimes young swimmers use air-filled water wings to stay afloat. When you removed this layer of air pockets (the peel) from the orange, it sinks a bit, just like what would happen if you removed water wings from some young swimmers. <em>(Note: The peeled orange will not sink.

The material in the box does not weigh very much, because there is a lot of air occupying the spaces between the cereal flakes (or between the popped corn kernels, which themselves contain a lot of air, too). The sand and rice grains are denser; they can pack together more tightly in the box.

Density is defined as the <strong>amount of mass per volume of a substance<\/strong>. Per always means divide.

But if you wrap your arms around your legs and curl up into a ball, you will sink. It all has to do with how much water is pushing against you and a little scientific principle called buoyancy. Ask, \u201cHave you ever heard that word buoyancy? What does it mean?\u201d<\/li>\n<p><\/p>\n<li>When you stretch out flat, more water pushes against you since your body is laid out flatter and has more surface area.

The object must make room for its own volume by pushing aside, or displacing, an equivalent (or equal) volume of liquid. The object is exerting a downward force on the water and the water is therefore exerting an upward force on the object. Of course the floating object\u2019s weight comes into play also. The solid body floats when it has displaced just enough water to equal its own original weight. This principle is called buoyancy. Have the children again say, \u201cbuoyancy.\u201d<\/li>\n<p><\/p>\n<li>The lump of clay pushed down on a small area of water, so it sunk. Why do items that are hollowed out seem to float best?

(the more dense, the less buoyant) What did you find out from the Coke and Diet Coke can activity? (it\u2019s sometimes difficult to guess buoyancy; ingredients can make a big difference) How can you change an object that floated before and make it sink? (changing its surface area\/crumpling it up) How does a boat or ship float carrying hundreds of pounds worth of cargo while that same cargo would sink to the bottom of the ocean if dumped overboard? (spreading out the weight along a larger surface area). Show me your body with less surface area (they should curl into a ball). Shoe me your body with more surface area (they should spread out their arms &amp; legs) What did you learn today while building your aluminum foil barge\/boat? What did you learn about Noah\u2019s Ark? What was your favorite activity we did today?<\/li>\n<\/ol>\n<h2>More Good Books on Buoyancy<\/h2>\n<ul>\n<li><em><em>Captain Kidd&#8217;s Crew Experiments with Sinking and Floating by Mark Andrew Weakland<\/em><\/em><\/li>\n<p><\/p>\n<li><em><em>Things That Float and Things That Don&#8217;t<\/em> by David A.
