Interactive Periodic Table

Teaching chemistry, physics, or a math class doing problems on exponential decay? Check out this spectacular interactive periodic table created by Michael Dayah. Among the awesome features:

1. pop-up windows showing Wikipedia entry for each element
2. temperature slider showing physical state of all elements at a given temperature
3. half-lives for every element (data for exponential decay problems in pre-calc!)
4. option to display every element's abundance in the universal, solar system, meteors, crust, oceans, and humans (uranium's abundance in humans: 1.0×10^-7%!)
5. electron orbitals with 3-D visualization
6. a useful About page telling students, among other things, how to cite the table in MLA and APA.

8th Grade Math Chapter 1 Test Preview

For the first 8th Grade Math test, you need to be able to...

• 1.1: Convert fractions to decimals, convert decimals to fractions.
• 1.2: Multiply fractions.
• 1.3: Divide fractions.
• 1.4: Add and subtract fractions.
• 1.5: Solve one-step equations involving fractions (3/4 + x = 1/2; 2/5*y = 1/4).
• 1.6: Solve two-step equations involving fractions (2/5*w + 1/2 = 3/2).

The test will give more problems focused solving equations.

You will complete this test without using a calculator.

Algebra 2: Chapter 1 Test Review

For the first Algebra 2 test, you need to be able to...

• Sec. 1.1: Use < and > to compare numbers.
• Sec. 1.2: Name the squares, cubes, & powers of from 1 through 10 without a calculator.
• Sec. 1.2: Use the order of operations to calculate answers.
• Sec. 1.3: Simplify algebraic expressions (distribute, combine like terms).
• Sec. 1.4: Solve equations (get x by itself!).
• Sec. 1.5: Rewrite formulas (turn d = rt into t = d/r).
• Sec. 1.6: Turn story problems into algebraic equations and solve.

The test will give more problems focused on simplifying expressions, solving equations, and rewriting formulas. The test will include one story problem.

You will complete this test without using a calculator.
