Others Like “Jack It Up! Lift a Load Using Hydraulics”

Science Fair Project Idea
thumbnail A ship is a busy place. When out to sea, naval, research, and fishing vessels pull or push heavy loads, like research equipment and crab pots, into and out of the water. But equipment and pots can weigh hundreds of pounds. So how does a ship's crew lift loads efficiently and accurately? With a hydraulic knuckle crane, of course. But what is hydraulics and why does hydraulics make certain tasks easier? Hydraulics is the study of liquids and their mechanical properties: how they move, resist… Read more

thumbnail Did you ever notice the cool patterns around your footprints when you take a walk in the wet sand at the beach? The pressure of your feet has effects far outside your footprints. Here's a project that uses a simple experimental apparatus to investigate how the volume of wet sand changes under pressure. Read more

Science Fair Project Idea
The insides of a car engine get very hot when the engine is running. Motor oil lubricates the moving parts, to keep the engine operating smoothly. What happens to motor oil as the engine temperature goes up? Read more

Safety Adult supervision required. Use caution when heating oil in the water bath, and when handling hot containers.
Science Fair Project Idea
thumbnail Here's a project that involves a different kind of sandbox than the ones you usually think of. This one has a moving wall inside, acting like a piston, to compress the sand. You can make layers using two different colors of sand, and then see what happens when you compress the layers with the piston. If you're handy with woodworking tools, this is a good project to give you a feel for the effects of geological forces that deform the Earth's crust. Read more

Time Required Long (2-4 weeks)
Prerequisites To do this project you should have some experience building things from wood. You will also need access to a reasonably well-equipped wood shop for building the apparatus used in this experiment
Material Availability Readily available
Cost Average ($50 - $100)
Safety Adult supervision required for using power tools
Science Fair Project Idea
thumbnail The world's oceans are home to the most strange and amazing creatures. What do scientists know about these deep-sea animals and how can they study them easily? One way to learn about these animals in their homes is to use underwater robots. Underwater robots can record data that would be difficult for humans to gather. But what are robots and how are they made? In this robotics engineering project, you will discover what makes up a simple robot and build and test your own underwater robot. Read more

Time Required Average (6-10 days)
Prerequisites None
Material Availability To build an underwater robot you will need a motor and a model boat propeller. See the Materials and Equipment list for details.
Cost Low ($20 - $50)
Safety You will need glue and epoxy to waterproof the motor for the robot. Follow the instructions that come with the glue and epoxy and always work in a well-ventilated area. If you have a latex allergy, you will have to exercise great caution with the balloon and ask a volunteer to help you. Keep fingers away from the spinning propeller to prevent injury. Do not test the robot in saltwater.
Science Fair Project Idea
thumbnail Have you ever had a cut or a bloody nose that seemed like it would bleed forever? Though it might have seemed like a long time, it probably did stop pretty quickly. This is because different factors in a person's blood normally work together to plug the opening caused by the cut in a process called blood clotting or coagulation. However, some people have a genetic disorder called hemophilia that causes them to bleed excessively. If a person has hemophilia, he or she is usually missing some of… Read more

Science Fair Project Idea
thumbnail The ingredients in Alka-Seltzer® tablets undergo a chemical reaction that produces carbon dioxide gas as soon as the tablets hit water. Do you think you can cause the tablets to produce gas faster by breaking them into smaller pieces before dropping them in water? Find out for yourself with this project. Read more

Science Fair Project Idea
thumbnail When you think about robots, chances are they are contraptions that you have seen on TV, in movies, or even in real life — and they are usually made of metal. What if you could make a soft robot that could bend, twist, or squirm like an octopus or an earthworm? Researchers at Harvard University have done exactly that, developing soft robots made of rubber and powered by air instead of electricity. In this project you will use their designs to build a soft robotic gripper of your own. Read more
