How Much Weight Can Your Boat Float?

Science Fair Project Idea

Scientific Method

Have you ever wondered how a ship made of steel can float? Or better yet, how can a steel ship carry a heavy load without sinking? In this science project you will make little "boats" out of aluminum foil to investigate how their size and shape affects much weight they can carry and how this relates to the density of water.

Have you ever wondered where the rain that falls from the sky comes from? You might say the rain falls from the clouds, but what are clouds and where do they come from? All these questions and many more can be answered by looking into how water moves on land and in the atmosphere, which is described in the water cycle. In this activity, you will investigate some of the processes that make water move in and out of the atmosphere by making a miniature water cycle model inside a plastic bag. Read more

Make a Robot Hand Using Drinking Straws

Science Fair Project Idea

Scientific Method

Imagine how cool it would be to build a robot hand that could grasp a ball or pick up a toy. In this robotics engineering project, you will learn how to use drinking straws, sewing thread, and a little glue to make a remarkably lifelike and useful robot hand. What will you design your robot hand to do? Pick up a can? Move around a ping pong ball? It is up to you! With these starting instructions, you can design any type of hand. You will simulate human finger anatomy as the basis for a… Read more
