People often call cardiovascular disease a "silent killer." This disease sneaks up and causes damage,
but patients don't realize it—until serious symptoms start. That is why physicians recommend keeping
your cardiovascular system healthy. A healthy cardiovascular system gives us the energy and the stamina
to do all of the things that we want to accomplish, such as do our best in school and perform well in sports.
But what makes a cardiovascular system unhealthy, and what are the…

Have you ever wondered how fun toys like Silly Putty®, Gak™, and Slime™ are made? These products are so much fun because of the properties of polymers, which make them delightfully bouncy, stretchy, sticky, moldable, breakable, hard, soft, and just plain fun! In this science project you can be the developer of your own slime product by changing the amount of a key ingredient. By observing the physical properties of your results, you can choose the best recipe for your new…
This is a great project for someone interested in both stargazing and photography. Bright city lights and even the light of the full Moon obscure the dimmest stars, which can make identifying constellations more difficult. In this astronomy science project, you will calibrate a digital camera to measure the skyglow in different locations. This can be a great tool to comparing the quality of different star viewing locations.
Digital cameras can be a great way to learn about photography. Most digital cameras today have LCD screens, so you get instant feedback on your photo. If you make a mistake, no problem, you just delete the picture. It's nice that you don't have to worry about the expense and bother of developing film! This project can help you learn to take better pictures.
The Science Buddies Bluebot Kit contains parts to build four different robots:
A motion-activated robot that uses a passive infrared (PIR) sensor
A light-tracking robot that uses photoresistors
A line-following robot that uses infrared emitter-detectors
An obstacle-avoiding robot that uses bump sensors
However, in each project, the sensors are hard-wired to control the robot's motors. This allows the robot to steer left and right based on input from two sensors, but it does not allow…
Watching a spacecraft launch is an amazing experience. It is thrilling to see it lift off and escape Earth's gravity. Did you know that it takes a chemical reaction to get a spacecraft into space? Every time you see a one blast off, you are watching chemistry at work. In this chemistry science fair project, you will also get to blast an object into the air. You will not be using the same fuel that NASA uses for the rockets that launch their spacecrafts; instead, you will use two simple…
Do you like to take pictures with a camera? It can be fun to capture important and humorous events in your life on film or on a memory card. Photography is a hobby that people of all ages enjoy because they can creatively express themselves both artistically and scientifically. But when did the science of photography start and have cameras always been such complicated pieces of equipment? In this photography science project, you will experiment with a simple camera called a pinhole camera and…
Measuring the value of a resistor with a multimeter is pretty simple. You set the multimeter to measure resistance, connect the two leads to the resistor (possibly using some handy alligator clips), and read the resistance value. This is called a two-point measurement (one probe on each of the two resistor leads). But what if the resistance you want to measure is very small, in the milli or micro-ohm (mΩ or μΩ) range? This can introduce problems because many low-cost multimeters…
Have you ever seen those cool wind tunnel pictures of cars with streams of smoke blowing over them? You do not need access to a wind tunnel to do a car aerodynamics science project! In this project you will use cheap, readily available materials—tape and yarn—to visualize airflow over a car. You will examine how you can affect the airflow over the car by making changes, like adding or removing accessories or making body modifications out of cardboard and duct tape. Maybe you can…
Before you head for school for the day, you might check the weather to see whether or not you need to wear a jacket or bring an umbrella. It is pretty easy for you to check the TV or internet to see what the weather will be like today, tomorrow, or even next week. The modern-day science of meteorology, or studying and predicting the weather, has many advanced tools at its disposal that make it easy for you to get this information.
How did people predict the weather before the invention of…
