SCIENTIFIC METHOD
1) What are the 6 steps of the scientific method?
2) Define Controlled Varialbles, Independent Variable, Dependent Variable, Control Group, Experimental
Group
3) 1 - Patty Power
Mr. Krabbs wants to make Bikini Bottoms a nicer place to live. He has created a new sauce that he thinks will reduce the production of body gas associated with eating crabby patties from the Krusty Krab. He recruits 100 customers with a history of gas problems. He has 50 of them (Group A) eat crabby patties with the new sauce.
The other 50 (Group B) eat crabby patties with sauce that looks just like new sauce but is really just mixture of mayonnaise and food coloring. Both groups were told that they were getting the sauce that would reduce gas production. Two hours after eating the crabby patties, 30 customers in group A reported having fewer gas problems and 8 customers in group B reported having fewer gas problems.
What is the control group? Experimental Group?
What is the Independent Variable, Dependent Variable?
What should Mr. Krabs’ conclusion be?
Why do you think 8 people in group B reported feeling better?
4) Slimotosis
Sponge Bob notices that his pal Gary is suffering from slimotosis, which occurs when the shell develops a nasty slime and gives off a horrible odor. His friend Patrick tells him that rubbing seaweed on the shell is the perfect cure, while Sandy says that drinking Dr. Kelp will be a better cure. Sponge Bob decides to test this cure by rubbing Gary with seaweed for 1 week and having him drink Dr. Kelp. After a week of treatment, the slime is gone and Gary’s shell smells better.
What was the initial observation?
What is the control group? Experimental Group?
What is the Independent Variable, Dependent Variable?

What should Sponge Bob’s conclusion be?

Make sure you can experiment using the scientific method to CORRECTLY test a single variable.

Write a testable hypothesis that clearly states the Controlled Vars, Ind. Variable and Dep Variable
DATA

Make sure you can evaluate the effectiveness of an example experiment (are their steps missing, does the test correctly test a single variable, is there a hypothesis?)
 Below write out 2 different experiments of your choosing… Make sure to include the following… o Problem, o Hypothesis, o Experimental Design (How is it set up, Independent Variable/Dependent Variables, Controls,
Control Group, Experimental Group)

You should be able to set up a line graph given a simple set of data.

You should be able to set up a series of bar graphs given a set of data.

Each graph must include all labels needed (title, axes, labels, key, etc.)
METRIC SYSTEM

List all the base units from the metric system (length, mass, volume)

List all the metric prefixes… Remember your pneumonic device!!!

With each jump between prefixes in the metric system, the amount changes by an order of
___________________. (How much do you multiply or divide by in one step)
456 m = _____________________ mm
675.69 km = ___________________ mm
345 kl = ________________________ml
6) 957.95 mg = _____________________ kg
7) For the following things answer with the correct measurements (meter, liter or gram)
 mass of a penny
 length of a football field
 amount of air in a basketball
 density of a marble
 use a graduated cylinder to measure this
 use a triple beam balance to measure this

You should be able to use a ruler, scale, and graduated cylinder to find length, mass, and volume respectively.

Calculate density, volume or mass given the other 2 variables in a word problem.
1) A block of lead has a volume of 15 L. The block weighs 1201 g. From this information, calculate the density of the block.

2) Define Density. Describe how liquids and materials layer based on their density (remember the density column lab)

INTRO TO MATTER
8) For the following things give the proper state of matter (solid, liquid, gas)

CO2

H20

Sugar
 metal
 steam

Fixed Shape and Fixed Volume

No Fixed shape

No fixed shape and no fixed volume
2) What is matter?
3) Identify the following as intrinsic or extrinsic properties:

Color

Mass

Volume

Malleability

Conductivity

Length

Reactivity
3) ID the following as Mixture, Element or Compound:
 water
 sand in water
 salt water
 oil in water
 milk
 carbon
 carbon dioxide
 hydrogen
What is a period on the periodic table? Give one example
What is a group on the periodic table? Give one example
How many valence (outer shell) electrons does Carbon have? Boron? Neon? Out of the 3, which is the most stable and why?

How many outer shells does Hydrogen have? Helium? Silicon?
Metals are likely to (give up or take) electrons while non-metals are more likely to (give up or take) electrons.
What are 4 properties of metals?
Draw the bohr diagram, for the following elements: a) Calcium b) Oxygen c) Flourine d) Magnesium
