Scientific Method
Leah, LaRenda, and Gabi decide to test what factors influence water absorption by an egg. They remove the shell from 3 eggs by dissolving them in vinegar. They create three different water solutions.
What is the independent variable?
Water solutions
It is 9:05
Observation
In a hypothesis the __________________ variable is what is being tested, while the _________________ variable is the one being measured in response.
Idependent, Dependent
If available, the body will always digest which macromolecule for energy first?
Carbs
Monomer of Nucleic Acids
Nucleotides
Leah, LaRenda, and Gabi decide to test what factors influence water absorption by an egg. They remove the shell from 3 eggs by dissolving them in vinegar. They create three different water solutions.
What is the dependent variable?
Egg Shell removal
There is water on the ground
Observation
What is the "cause"
indepdendent
The macromolecules that would most likely be involved in contracting muscles would be .
Proteins
What is the monomer for lipids
Fatty acids
Leah, LaRenda, and Gabi decide to test what factors influence water absorption by an egg. They remove the shell from 3 eggs by dissolving them in vinegar. They create three different water solutions.
What would a control variable be?
An egg in just water.
I see Sally sweating. Sally just went on a job.
Observation...then inference.
What is the "Effect"
Depdendent
We obtain all macromolecules we eat except...
Example of Carbohydrate
Starches
Leah, LaRenda, and Gabi decide to test what factors influence water absorption by an egg. They remove the shell from 3 eggs by dissolving them in vinegar. They create three different water solutions.
List three potential constants.
Amount of solution, weight of egg, scale measurement, time in solution..
What makes something an inference?
It is an assumption based on an observation
What format is a hypothesis in, be specific in independent and dependent variables.
If (IV), then (DV)
List the order our bodies absorb macromolecules
1. Carbs
2. Lipids
3. Proteins

List a hypothesis.
What defines something as an observation?
You must use one of your five senses
If a player practices longer, then he will score more points in the game.
What is the independent and dependent variables?
DV - points in game
