In high school we have to do a 200 word abstract that belongs in the front of our research paper. So it’s very important, unless you want points counted off.

Hi. I need middle school-level science project ideas for my science fair. Please don’t make it too complicated as I need to have it by April 16th. Also, please no links, because if you send me a link, I’ve probably been to that site a dozen times already.

Thanks SO much!
By the way, I live in the city, so I have no yard for backyard demonstrations/experiments/projects. Thanks.

Just construct a wind mill with the help of cycle wheel and funnel on its circumference. This will drive a small generator. You can use any toy motor and connect it via belt to increase the speed. You can connect LED to show the illumination.

-lithium oxide
-magnesium sulfide
-aluminum fluoride
-potassium nitrate

Also, How did you know how many of each ion to write in the formula?

Thanks so much for helping! I guess it’s hard for me since this is all new for me?

This is pretty hard for middle school!
But as my Chemistry teacher liked to say, Chem is try (get it? chemistry)

Anyways….

-ide is a suffix that means negatively charged, aka has space for taking on positively charged ions.

What comes before the suffix is the chemical that is negatively charged. In your case oxygen, sulfur, fluorine, and nitrogen.

A *general* rule is that the very last column (starting with He, Ne, etc) has 0 negative charges. The 2nd to last column (starting with F, Cl, etc) has one negative charge. This goes on backwards till you go 4 (or is it 5?) columns backwards.

A similar *general* rule is that the first column (starting with H, Li, etc) has one extra positive charge. The second column has 2, and so on.

So lithium oxide, for example, has lithium (one positive charge) and oxygen has 2 negative charges. You want the total charge to be zero. So you need 2 lithiums (+1 x 2 = 2) for your one oxygen (-2 x 1 = -2) to get zero (+2 + -2 = 0).

So the way that you would write that would be:

2 Li^-1 + O^-2 -> Li_2O

(The ^ means superscript and the _ means subscript… you may know that, but I didn’t in middle school). See the Wikipedia page below to see the notation for the left hand side to get an idea if you don’t know what I’m talking about.

Magnesium sulfide would look like:

Mg^-2 + S^-2 -> MgS

Both have the same but opposite charge so you don’t need to double (or triple) up to balance the charges.

Hope that helps and good luck. Chemistry really isn’t that bad once you get past all the background stuff like what you’re doing right now.

We just need help choosing the topic???Can you help us choose a topic that is fun to do with three people???Thanks-you

How about the dangers of some things found within the household such as using inhalants (’huffing’ fumes) or playing ‘the choking game’ or even those teens that chug robitussin (over-the-counter/otc cough medicine) that can cause dangerous hallucinations (Any hallucinations can be ‘dangerous’ though) and can be addictive and lethal. A friend has a traumatic brain injury (tbi) and bone marrow (fatty inner lining of bones that makes blood cells) damage from huffing at age 12, now in her 30’s. It can be very interesting to research as well as priceless information for both you and your peers.

I once saw a photo from a science/community fair which showed a mother who had tragically lost her son due to inhalant use and she had a table display of enlarged pictures of makeshift products that can mame or kill. An example of what was displayed was a tube of glue that instead of the name ‘rubber cement’ or ’superglue’ on it, she printed ‘brain eraser’ or such.

any good ideas? all i really need is a research question.

Can our parents be too nurturing?

It has to be related to biology and also i am willing to spend a little money on it…not too much though

When I had a science fair I did something to do with what your lungs look like when you smoke. You put a couple of cotton balls in a sandwich baggie and then get a cigerate and make the cotton balls turn black which is suppose to be what your lungs look like when you smoke. You just put some more information of your own about smoking and your done! I got a C on that and won 3rd place when I was in 5th grade

I’m in 8th grade and I need to come up with a good idea for a science project. My teacher takes this very seriously. Any suggestions?

According to the theory of evolution, which of the following processes leads to adaptive changes in the genetic makeup of a species over time?
A. Genetic differences among
individuals in a population make
some individuals more likely to
survive and reproduce than others.
B. Physical changes in individuals
that are caused by environmental
conditions are passed on to their
offspring through their genes.
C. Environmental changes produce
mutations in the genes of individuals
that help their offspring
survive and reproduce.
D. Populations of individuals with
relatively low mutation rates eventually
replace populations that have
unstable genetic material.
What’s the best way to understand this theory and Natural selection as well? aren’t there 5 parts to natural selection? Do you have a website link that best explains all this? b/c not only would I like to understand this question, but others like it

The best answer is A.

Natural selection is very simple. Those organisms with the best genes for the organisms’ survival in its environment are more likely to be passed on to fertile offspring. Changes in the genes of the germ cell line are passed on to the next generation, and if the genetic changes make offspring more fertile in their environment, the frequency of the gene will rise in the population.

Note that changes in the environment may favor new genes to cope with the changes. Also, keep in mind that the genetic changes are random, but the selection process is not.

This is survival of the fittest, where fitness only means producing fertile offspring.

what are the parts of it that all teachers are looking for and that have to be in the packet and on the board? both please seperately

the scientific method of course. all the steps hypothesis, procedure, observation, results, conclusion…. etc. all that and the presentation. if it was challenging and if you did an awesome job. presentation always count. it has to be neat and awesome looking. even the simplest of science fair project make it to display if it’s presentable.

How do I get a certificate after being away from teaching for about 25 years?

too vague – here is what is needed to answer correctly:

Were you certificated before? All states have a method for recertification.

which state? every state has different rules on this.

until I know more: go to your states website, look for credentialing rules.

If you have never been certificated, then its: credentialing program, tests and student teaching.
