How do drones automatically balance themselves when you let go of the controls? Find out in this project as you build and program an experimental setup to make a drone automatically control its tilt angle about a single axis.

Remember going to the doctor and getting vaccine shots? It's no fun getting poked with a needle, but fortunately, a vaccine gives you protection against a serious illness for years to come. This project will show you why.

Have you ever tried to pull out a nail out of wood with your bare hands? Or have you tried to shove a staple through a stack of papers without a stapler? A hammer's claw, a stapler, a pair of pliers and a shovel are each examples of everyday tools that use levers to make our work easier.

Science and math abound in baseball. In this project, you can produce some interesting baseball statistics of your own and perhaps settle a long-standing debate. You'll set up experiments at your local playing field to find out which type of bat is better, wood or aluminum.

Sometimes bats can "whoosh" right by you, and not be seen. In this science fair project, you will be able to detect flying bats by listening in on the ultrasonic signals they produce to locate objects in their environment. The bat detector is a useful and fun tool for studying the biology of this nocturnal flying mammal.

With this project you'll send ping pong balls flying through the air with a rubber-band powered catapult. This catapult makes it easy to reproduce the launch angle, and to measure the amount of force applied to the projectile. Armed with this information, find ways to keep the ping pong balls flying accurately on target.

In this activity, you build and test two types of bridges: a simple suspension bridge and a beam bridge. Which bridge design is stronger?

In this science activity, you will make a little toy raft that is powered by surface tension, and use your vessel to investigate how surface tension works.

In this fun activity, you will build your own simple bottle centrifuge and test how it works.

In this activity, explore the distinct characteristics of a river by creating a river model inside a pan with sand, pebbles, and real water.

Build your own bathtub or pool toy from simple craft materials in this fun activity. You will build a rubber-band-powered boat that can zip across the surface of the water after you wind up the rubber band.

Find out what makes a bridge strong in this fun activity as you build simple bridges with paper and test to see how much weight they can hold.

Will using agrofuel offer a substantial alternative to using fossil fuel? With this experiment you can compare the amount of heat energy released by agrofuel and fossil fuel. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on terms, concepts, and questions, bibliography, list of materials and equipment, experimental procedure, suggestions on how to vary the experiment, plus a focus on the sort of careers this experiment might relate to.

One of the characteristics that makes M&Ms so popular is dye that colors the hard shell, and of course the chocolate. But, many are unaware of what dyes are used to make those colors. This day long lab uses paper chromatography to explore the many different dyes that give your favorite candies their color.

This Science Buddies site lays out the requirements needed to become an aerospace engineering and operations technician, as well as the education and job description. Included are interviews with people who have pursued this career. Try out some aspects of this career by doing some of the projects referenced on the site.

We all expect that the food we eat is safe. Agricultural inspectors are the ones who check food processors, farms, and businesses to assure that they are following the governmental regulations that protect our food safety. This Science Buddies site lays out the requirements needed to become an agricultural inspector, as well as the education and job description. Included are interviews with people who have pursued this career.

As the world's population grows larger, it is important to improve the quality and yield of food crops and animal food sources. Agricultural technicians work in the forefront of this very important research area by helping scientists conduct novel experiments. If you would like to combine technology with the desire to see things grow, then read further to learn more about this exciting career.

Do you think a career in animal breeding might be interesting? This article in Science Buddies gives a clear assessment of what you might expect in that career. Find out what education you need, what the work environment is like, and what the job itself entails. Included is a video that explains the responsibilities of an animal breeder.

Animal trainers are needed in many circumstances. From training animals in animal parks to training service animals, there are many opportunities for those interested in this career. Science Buddies gives a good overview of what is necessary in terms of education, work environment, and on the job requirements. Included are interviews with individual animal trainers and a video showing a trainer at work.

Does examining all aspects of human life appeal to you? Would you like to explore the origins of man, of language, of culture? This Science Buddies site gives a good overview of what is involved in the career of anthropologist. Find out what education you need, what the nature of the work is, and what your on the job responsibilities might be. Included are interviews with anthropologists and a video about "Ardi," one of the most important fossils ever found.
