For your report, you should research your element from several different sources. Some things to include are:
- What does your element look like? What state is it in at room temperature? Can it take different forms? (for example, carbon can exist as graphite, which is pencil lead, or diamond!)
- What are its properties? Does it conduct heat or electricity? Is it a metal, non-metal, or metalloid? How dense is it? (This is given as a number. For example, the density of water is 1 gram per cubic centimeter. If your element is less dense than water it will float, and if it is more dense than water it will sink!)
- Where do we find your element? Is your element found lots of places on Earth, or is it hard to find? Where do we find it? (For example, is it found in a certain type of rock? Is it part of the air?)
- What do we use your element for? Is your element useful for anything? Where might we have seen your element in everyday life?
- Anything else interesting? Is your element unique or special in any way? Tell us about it!
Remember, your report should be in your own words–not copied from a webpage (we can tell!). Try searching on Google, or finding your element’s video on the periodic table of videos (search google or youtube for “periodic videos <element name>” to find it).

Elements report
Do you know that nitrogen is so important and interesting? Nitrogen’s atomic number is 7 and its chemical symbol is N. Its state at room temperature is a gas. Its other forms are dinitrogen which is its most common form, nitrate that is used by plants, ammonium nitrogen that’s taken by plants, and organic nitrogen which exists in many forms for example ammonium and nitrate. Nitrogen is a nonmetal because it’s a gas and its density is 1.251 and because of that it is slightly more dense than water and conducts electricity. You could find nitrogen everywhere since it’s in the air and in every living thing for example people and animals. This element is what we breathe, use to make building blocks of our proteins, and is found in fertilizer to explosives. Some other interesting facts about nitrogen is that its 79% of the air we breathe, when you crack your knuckles the cracking sound is actually nitrogen gas bubbles popping, its responsible for the colors of the aurora, and is 78% of the Earth’s atmosphere.

I bet you know what copper is, but you may not know everything about it! Copper is an element that is used for phones, cars, and pennies just to name a few uses. Even The Statue of Liberty is made out of copper!
First, copper looks like a reddish brown color. It is a solid at room temperature, and it can take many forms. It can make different compounds including the following: copper salts, copper oxide, brass and zinc.
Second, copper can conduct heat and electricity very well. Copper is actually a metal. Copper’s density is 8.92g/mL so if you put it in water it would sink. Copper is 7.92g/mL more dense than water. You can even try it at home and try to prove me wrong!
Third, copper is used in everyday life. You may not think so, but your phone, doorknob, and car use copper. There are also many more uses for this element. You might see it in your money, jewelry, wires, and even kitchen appliances.
Finally, copper can also be a bad thing. If you don’t have enough in your body, it can cause grey hair, skin wrinkles, crow’s feet, and shaggy skin. Copper is often compared to the “fountain of Youth.” It improves your body from having facial problems and helps hair stay its natural color.
Now, you should know more about the element copper. Try to do as many experiments as possible with copper or any other element that is safe. While doing your experiments, try to accomplish the goal of doing a question, hypothesis, observations and conclusions.
