Science Fair Project Idea
thumbnail What do rocks and clocks have in common? Both keep track of time. Yes, radioactive isotopes present in rocks and other ancient material decay atom by atom at a steady rate, much as clocks tick time away. Geologists use those radioactive isotopes to date volcanic ash or granite formations like the giant Half Dome in Yosemite National Park. Anthropologists, archeologists, and paleontologists also use radioactive isotopes to date mummies, pottery, and dinosaur fossils. Does this sound abstract… Read more

Science Fair Project Idea
thumbnail In our , we provided a template with four materials: two active materials that expand and contract in the physics sandbox mode, and two passive materials — one hard and one soft. The project mentioned material properties, but it did not go into much detail — you just used the default settings from the template. Changing the material properties can drastically change how your robots behave. Engineers must take material properties into account when designing robots and other machines.… Read more

thumbnail In our , we provided you with a template file that included default material properties and physics simulation settings. These settings include friction, gravity, and temperature — all of which can drastically change how fast your robots move. However, we did not explain what exactly all these physics simulation settings meant, or how to change them. You can access the physics settings through the Physics Settings tab after entering the Physics Sandbox mode, as shown in Figure 1: [[… Read more

Science Fair Project Idea
thumbnail 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

Safety

You will be working with radioactive material in this science project; it is completely safe as long as the simple safety instructions in the Procedure are followed.

This project uses isopropyl alcohol, a flammable product. Do not use it near an open flame or anything hot.

Dry ice is colder than regular ice and can damage your skin. Wear insulating gloves when handling it.

If you choose to take apart a smoke detector, be very careful when cutting through metal or plastic. Cut edges might be sharp. Adult help and supervision is required. Minor injury is possible.

thumbnail In our , you were challenged to use the VoxCAD software to design the fastest possible robot using different materials. However, we did not ask you to think about one big thing — efficiency. It is great to design a robot that is very fast, but what if it also consumes a lot of energy? Engineers must consider this when designing robots in the real world — robots that use more energy to move will drain their batteries faster, which can be a problem. This is similar to the concept of… Read more

thumbnail Do you know someone who has an autoimmune disease? Autoimmune diseases are fairly common, affecting more than 23.5 million people in the United States, which is about 1 in 13 people! You may have heard of some of them, such as diabetes (type 1), rheumatoid arthritis, and celiac disease. Many autoimmune diseases are poorly understood, but they all have one thing in common: they happen because a person's immune system (which normally fights off germs to keep the person healthy) attacks the… Read more

thumbnail In baseball, coaches use hit charts to track the results of every hit each player makes, giving a measure of the player's performance. Have you ever wondered what things affect where a baseball goes when a player hits it with a bat? In this project you will set up an experiment to hit a ping pong ball in a controlled manner using a toy catapult, then learn about the physics of baseball by making your own hit chart. Read more

thumbnail We use passwords every day for our email and other computer accounts. How secure is the password that you use? How hard would it be for someone to guess your password? How hard is it to write a computer program to guess a password? You can see for yourself by writing a simple password guesser in the computer language Python. We will get you started with some ideas, a little sample code, and a few passwords for your computer program to try and guess. Read more

thumbnail If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will… Read more

thumbnail Jumping discs can be a fun toy to play with, and with their sudden POP!, they can even be a good way to startle people who have never heard them before. Jumping discs use a neat trick to jump. They are made of two different types of metal, and these metals expand when they heat up (or shrink when they cool down), but not by exactly the same amount. In this science project you will explore how temperature affects the reactions of your jumping discs— and how to get the timing right if you… Read more
