US Department of Education Free Resources
Link to all kinds of great resources for all subjects, but the science pages are especially good. There are great pages for chemistry, physics, and life sciences. Every time you visit the site, a different activity is featured. You can research just about any project here.

Create a Graph
Also from the Department of Education, you can choose from many different types (pie, bar, line), input your own data, and even customize the color scheme. This is a great tool for labs, science fair, and allowance tracking!

Interactive Periodic Table
Link to a really great periodic table. Click on the element's symbol to see a picture of what it looks like, hear how to say it, and find out more about it.

Periodic Table of Videos
This periodic table has a short video about each element on the periodic table. If it explodes, glows, smokes, or changes color, you'll see it here.

ACS Periodic Table
This periodic table is published by the American Chemical Society (ACS). It has a lot of historical information about each element, including famous scientists. Super for report writing!

The Why Files
This site tells you all of the science behind the news, including everything about Hurricane Katrina, global warming, and high oil prices. This is a great site to search for researching a project.

What's that Stuff?
This is yet another great research site. Ever wanted to know what the stuff inside a glowstick is, or what Cheez-Wiz really is? How about What makes a sticky note sticky, or what new car smell is? This site tells about what all sorts of ordinary and not so ordinary things are made of.

The Element Song
Haven't you always wanted to memorize all of the elements? This song is brilliant!

Brainteasers:

1) This problem requires basic algebra, but it's pretty hard. Let 'a' and 'b' be two variables that are equal, so that a=b. From these two variables, we can show that 2 is equal to 1:

Given: a = b
Left-multiply both sides by a: a*a = a*b
Subtract (b*b) from both sides: a*a-b*b = a*b-b*b
Factor both sides: (a-b)*(a+b) = (a-b)*b
Cancel (a-b) from both sides: (a+b) = b
Replace a with b (given, see line 1): (b+b) = b
Simplify (b+b) to 2b: 2b = b
Answer: 2 is equal to 1: 2 = 1

What is wrong with this reasoning?

2) This one is easy as pie! Fill in the blanks with five different numbers so that it makes sense when read aloud:

We had been on a losing streak __________ much __________ long, but today we finally __________. To celebrate, we __________ __________.

Good Luck!

There are 11 elements with names that can be spelled using only the symbols found on the periodic table. For example, Neon can be spelled using Ne (Neon), O (Oxygen), and N (Nitrogen) - (Ne)(O)(N). On the other hand, lead can't be spelled because there is no symbol (L) or (Le). Can you put together the other 10? If you can get 9 out of 10, the movie ticket is yours!
