"The blue pen will fall faster than the red pen." is an example of this type of hypothesis.

Alternative

200

"There is no difference between pen color and rate of falling." is an example of this type of hypothesis.

Null Hypothesis

300

Now that I have my hypothesis in place - what is the next step I should take?

Conduct the experiment

400

In the hypothesis: "The blue pen will fall faster than the red pen", what is the dependent variable? 

Time it takes the pen to fall

500

Name one thing that could be a control group in an experiment testing how fast different colors of pen fall.

Air temperature, speed, same amount of ink in each pen, etc.

Cell Chemistry

100

If you look at the periods of a periodic table, they can tell you this piece of information. 

# of electron shells

200

This specific type of bond can be seen between the nitrogenous bases of DNA.

Hydrogen bond

300

The pH scale is based on the number of this type of ion in a solution.

Hydrogen ions (the more Hydrogen ions, the more acidic)

400

Detergents help break up dirt particles by forming micelles around them. What is the name of this property that allows a micelle (or phospholipid bilayer) to form?

Amphipathic (hydrophilic head, hydrophobic tail)

500

The atomic number of Magnesium is 12. This means it has this many electrons.

12

Vocabulary
