Throughout history there have been a lot of myths that have been taken as fact. For example the fact the earth is round – pre Christopher Columbus most of the modern world thought the earth was flat. As hard as it may seem, today there are still myths that many people believe to be fact. […]
Solar energy has many uses such as electricity production and heating of water through photovoltaic cells and directly for drying clothes. Solar energy can also be used to heat swimming pools, power cars, for attic fans, calculators and other small appliances. It produces lighting for indoors or outdoors. Solar energy has many uses such as […]
If you need to collect data that involves length measurements then these conversion factors will be helpful: 1 centimeter = .394inches 1 meter = 39.4 inches 1 meter = 3.28 feet 1 kilometer = .621 miles You may need to use length measurements in your fuel cell car science fair projects.
Multiples of SI units are very important to understand when you are collecting data that have large measurements. Some of the most common prefixes for multiples of SI units include: hecto- which is 10^2 power, kilo- which is 10^3 power, mega- which is 10^6 power, giga- which is 10^9 power and tera- which is 10^12 […]
It is important to understand the prefixes used to describe subdivisions of SI units. For example, pico- means 10^-12 power, nano- means 10^-9 power, micro- means 10^-6 power, milli- means 10^-3 power and centi-means 10^-2 power. Keep these prefixes in mind when creating your own energy science fair projects
In order to make the understanding of data universal the International System was developed. This system standardized measurements for nearly everything that scientists are interested in measuring. Here are a couple of examples: meters, joules, seconds and watts. These are the measurement units that you will need to use in your energy science fair projects
An insect’s blood is yellow, light green or clear. If you squash a blood and see red you can be sure it is the blood from someone that is sucked! A mammal’s blood is red. Is a lobster’s blood is blue or clear? What color is your blood?
