Paper Bridge for Pennies

Science Fair Project Idea

Scientific Method

Using just a single sheet of paper (8.5 x 11 inches) and up to five paper clips, can you build a bridge that will span 20 cm and support the weight of 100 pennies? The area beneath the span must be free (so that boats can pass beneath it). To test your bridge, place two books 20 cm apart, and set the bridge on the books, spanning the gap. Do not fasten the bridge to the book (nor to any other support). Does your bridge hold as much weight as you expected it would? If your bridge fails… Read more

Paper Circuits Science Projects

Blog Post

Use these free STEM projects and activities to learn about circuits and make interactive paper circuits with K-12 students. Teach About Circuits! With "paper circuits," students can learn about circuits and design and build their first circuits on a piece of paper. Paper circuits are great for introducing students to circuits because the materials are simple. With copper tape, an LED, and a coin cell battery, students can assemble a circuit, learn… Read more

Paper Maze Programming: Start to Finish Computer Logic

Blog Post

Explore the logic of computer coding — no computer required! Have you ever asked your student to give you directions, turn by turn, to get you home from a familiar landmark? It can be eye opening to hear how they might guide you, and you may or may not make it where you need to go! But the process of giving directions helps reiterate the steps involved in moving along a frequent path. Writing a computer program is similar in many ways. You need… Read more

Did you know that not all animals use their ears to ‘hear’ sounds? Snakes, for example, perceive sound waves through their jaw bones! And many insects perceive sound waves through their antennae. While these methods of detecting sound might be different, they all respond to the same thing that our ears do, which is sound waves in the environment. In this activity you will generate some impressive sound waves from very simple materials, and observe how these sound waves are… Read more

Particles in the Mist: See Radioactive Particles Decay with Your Own Cloud Chamber!

Science Fair Project Idea

Scientific Method

Are you fascinated by radioactivity and the emission of particles caused by the disintegration of an atom? This science project enables you to observe safely a spectacular display of radioactive decay. Following the instructions in the Procedure, you will be able to isolate a safe radioactive source and build a cloud chamber to watch the radioactive decay. Then you will use your cloud chamber to discover if a plastic lid can shield you from this type of radioactive decay particles. Read more

A popular science demonstration shows that when you overlap the pages of two phone books, they are nearly impossible to pull apart. Since most people do not have two phone books sitting around, we will show you how you can do the same experiment with sticky notes. Sticky notes are much smaller than phone books, so they should be easy to pull apart, right? Try this activity to find out! Read more

Have you ever spent time spinning a hula hoop around your waist or arm? Could you easily do it, or was it difficult? Have you ever wondered how hula hoops work, or, in other words, what makes them be able to spin around a person's waist or arm? It comes down to the physics that is involved. Physics can help you determine what makes one hula hoop a winner and another a flop. In this activity you will get to create your own hula hoops and investigate how their masses affect how they spin. … Read more

Pick a Card, Any Card

Science Fair Project Idea

Scientific Method

No matter what your favorite card game is, we all wish we could use psychic powers to draw the card we want on our turn. You may not have psychic powers, but you might have the power of probability on your side. In this science project, you will discover how math can help you avoid the words, "Go fish!" Read more

PID Controller Tuning for a Drone

Science Fair Project Idea

Engineering Design Process

Note: to do this project you will need the DIY Mini Drone Kit, available from our partner Home Science Tools®. An Arduino must be purchased separately. The Electronics Kit for Arduino, available from our partner Home Science Tools®, contains the additional parts you will need, including an ultrasonic sensor. The program in the DIY Mini Drone: Arduino™ Altitude Control project uses a proportional controller to control the drone's altitude. A potentiometer is connected to one… Read more
