What should I bring to my 7th grade science class as an element?

Question

I have to bring in 6 elements to my science class tommorrow and my teacher said it can't be anything like water or air or whatever...What should I bring in? (Something that I should have lying around my house)

Answer 1

There are some very common elements that you use every day. Aluminum foil is elemental aluminum. The graphite (lead) in your pencil is elemental carbon. Any cast iron (pans, candle holder, fire place tools) is elemental iron. You could bring a coin (pennies used to be pure copper), or a nickel (don't think it ever was made of nickel). Any old copper plumbing is copper. Put some table salt in water. Then you would have suspended sodium and chlorine ions in the water. Get a helium balloon from your local flower shop, That is elemental helium. Starting to get the idea? There really is a lot of stuff that are elements. Just remember that things like wood, sugar, steel and bronze are all compounds, not elements. I just rembered another one. Bring in a thermometer. Some of those still use elemental mercury.

Answer 2

I hope your elemental samples don't have to be pure -- rather they need to be examples of the element. So, here are some ideas:

A piece of charcoal -- Carbon
Aluminum foil -- Aluminum
a penny -- Copper
a nickel -- Nickle
a nail -- Iron

If you have any gold or silver jewelry or coins, those would be obvious examples.

If you have a smoke detector, you can borrow it for long enough to show the Americium ionizer.

And, for a lark, you could bring a plastic bag filled with air -- representing the elements nitrogen (78% of air) and oxygen (21%).

Answer 3

Carbon - burnt toast, charcoal
Aluminum - pots, pans
Iron - nails, other hardware
Copper - penny
Silver - jewlery
Gold - jewlery

Maybe you could memorize and sing this song for your teacher...

``There's antimony, arsenic, aluminum, selenium,
And hydrogen and oxygen and nitrogen and rhenium
And nickel, neodymium, neptunium, germanium,
And iron, americium, ruthenium, uranium,
Europium, zirconium, lutetium, vanadium
And lanthanum and osmium and astatine and radium
And gold, protactinium and indium and gallium (inhale)
And iodine and thorium and thulium and thallium.

``There's yttrium, ytterbium, actinium, rubidium
And boron, gadolinium, niobium, iridium
And strontium and silicon and silver and samarium,
And bismuth, bromine, lithium, beryllium and barium.

``Isn't that interesting?
I knew you would.
I hope you're all taking notes, because there's gonna be a short quiz next period.

``There's holmium and helium and hafnium and erbium
And phosphorous and francium and fluorine and terbium
And manganese and mercury, molybdinum, magnesium,
Dysprosium and scandium and cerium and cesium
And lead, praseodymium, and platinum, plutonium,
Paladium, promethium, potassium, polonium, and
Tantalum, technetium, titanium, tellurium, (inhale)
And cadmium and calcium and chromium and curium.

``There's sulfur, californium and fermium, berkelium
And also mendelevium, einsteinium and nobelium
And argon, krypton, neon, radon, xenon, zinc and rhodium
And chlorine, carbon, cobalt, copper,
Tungsten, tin and sodium.

``These are the only ones of which the news has come to Harvard,
And there may be many others but they haven't been discovered.''

Answer 4

bring some dirt and a match :P
and there are only 4 main elements, earth, air , fire and water though:P

unless of course you mean the rest from the periodic table
then you could bring in a metal which could be also be easy such as tin, copper coin etc.

Answer 5

water is not an element, it's actually a mixture of two elements (H, O)

If I were you, I'd bring a soda can (Al), a gold chain (Au), a silver chain (Ag), salt (Na, Cl), and a penny (Cu)

that sounds about right for a 7th grade science class. hope it helps =)

Answer 6

maximum freeze-dried foodstuff so which you may purchase at carrying products shops is analogous to astronaut meals. mixed with water and heated makes gravy, meat and vegetables. Puddings, potential bars, lemon drops, are styles of candies that save and are undemanding to eat with out mess in weightlessness. there is even a action picture scene on the thank you to Mars the place an engineer makes a DNA double spiral helix out of M&Ms floating in midair. i'm specific our NASA adult males observed that action picture.

Answer 7

Bleach (Chlorine)
Calcium supplement
something with chrome plating (Chrome)
a penny (copper -- though most are made of other stuff now!)
Aluminum foil (Aluminum)
A can (Tin -- though, again, many are made of something else)
something silver, if you have it, or silver plated
same with gold
a diamond (carbon)

just some thoughts -- hope it helps!

Answer 8

aluminum foil, salt, gold (jewelry)
