The egg drop project is a time-honored tradition in many science classrooms. Students build a device to protect an egg and prevent it from breaking when dropped. This project typically relates to lessons about Newton's laws of motion or potential and kinetic energy. However, it is also a great way for students to practice the engineering design process, and learn about the importance of design iteration and learning from failure. Read more

NGSS Performance Expectations:

MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

NGSS Performance Expectations:

MS-PS3-5. Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from that object.
MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

Effect of Trebuchet Arm Length or Counterweight Mass on Projectile Distance

Science Fair Project Idea

Engineering Design Process

Before cannons widely replaced them, siege engines were often used by armies to throw large stones and other projectiles to break down castle walls. One of the most advanced siege engines used in the Middle Ages was the trebuchet, which used a large counterweight to store energy to launch a payload, or projectile. The horizontal distance the payload would travel is called the trebuchet's range. Figure 1, below, shows a modern reconstruction of a trebuchet. The range of a trebuchet has… Read more

Lift a Load Using Hydraulics

Science Fair Project Idea

Scientific Method

Can you lift a car? No? You say you are not strong enough? True, our bodies are not built to lift heavy loads like cars. Fortunately, our brains are smart enough to harness the power of fluids, like water and oil, to create hydraulic lifts. By pushing a button on a hydraulic lift, a mechanic can easily raise a car with one finger. Lifts can also be used to raise lots of other heavy loads - even such massive things as steel girders to construct a skyscraper! In this mechanical engineering… Read more

Bombs Away! A Ping Pong Catapult

Science Fair Project Idea

Scientific Method

If you were in a raiding army in the Middle Ages, a catapult would come in mighty handy for taking down castle walls. But only if you could aim it reliably! With this science project, you will try your hand at catapult technology. Using a rubber-band-powered catapult you will send ping pong balls flying through the air. The catapult's design makes it easy to measure and repeat how hard the ball is launched and its direction, so you can find the right catapult settings to hit the target reliably. Read more

Marble Machine

Science Fair Project Idea

Engineering Design Process

Put your engineering skills to the test to see if you can build a machine—powered by nothing but gravity—that will automatically sort out two different sizes of plastic spheres. That might seem like a strange task, but have you ever used a coin sorter to separate pennies, nickels, dimes, and quarters? How about using a sifter in the kitchen to separate fine grains of flour or sugar from bigger lumps? Machines that can automatically sort objects or particles of different sizes are… Read more

Volleyball Machine Challenge

Science Fair Project Idea

Engineering Design Process

Can you build a volleyball machine? It will need one part to launch a ping pong ball over a net and another to return the ball. How many back-and-forth volleys can you get before the ball touches the ground? Looking for inspiration? You can see how other students have tackled this and other annual Science Buddies Engineering Challenges. Teachers, lesson plan versions of this challenge are available. Read more

Are paper airplanes a nuisance in your classroom? They don't have to be! Those distractions can be a constructive learning opportunity: use them to teach your students about the engineering design process. In this fun lesson, you will be the "customer" ordering a paper airplane, and your student teams will be engineering companies that will manufacture planes. Before they start making planes, they need to define the criteria and constraints of this engineering problem. Read more

NGSS Performance Expectations:

3-5-ETS1-1. Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.

Before the Industrial Age, people had to rely on muscle power to move and lift heavy objects. Simple machines like pulleys, levers, and ramps made it easier for humans to lift heavy objects like rocks and logs. In this project you will use simple household materials to explore one of these classic machines – the pulley. Read more
