Step 1: State the problem
description: define the problem as clearly as possible.
Example: The front brakes are making a loud noise.
Step 2: Gather information
description: Gather data about the problem and make good observations using all 5 senses.
Example: He checked all his other songs and found they all did the same thing.
Step 3: Form a hypothesis
description: a prediction that can be tested.
Example: Luke decided he would try a different set of headphones and see if that helped.
Step 4: Test the hypothesis
description: Use an experiment to test your logical answer to the problem.
- Use controlled conditions to test your hypothesis
A. Controlled experiment: Everything in an experiment that is the same except for the variable.
~ Variable: Something in an experiment that you change, only one per experiment.
~ Constant: Factors in an experiment that stay the same.
Example: Luke asked to borrow 3 diffetent friends' headphones. All the headphones were the same brand. After switching the ears, he found all the headphones worked. However, Luke tried the headphones in his friend's ipod and found they didn't work.
Step 5: Analyze Data
description: go over all the data you have and go over conclusions.
Example: Luke wrote down all his findings and read over all his notes.
Step 6: Draw a conclusion
description: Based on data and observations, conclude the answer to your hypothesis.
- should be logical answers to the question based on data and observations.
- if needed, retest this theory ( possibly with a new hypothesis)
Example: Luke concluded with his data and and observations that his headphones were broken and he needed a new pair.
Step 7: Share results
description: report journal to classmates, or publish a journal of findings.
Example: Luke shared his findings with his mom and friends, and his mom bought him another pair for his birthday.
I hope this helps!
Answer:
A negative charge exists because of the electronegativity of oxygen. A polar water molecule is made up of hydrogen and oxygen. Due to its atomic structure, there is an unequal distribution of charges and thus oxygen gets a more negative charge while hydrogen gets a positive charge.
Explanation:
Genetic variation. We all have different gene expressions and often times we have different parent cells than somebody else of the same species, though, it's possible to share similar characteristics.
The pH scale measures how basic or acidic a substance is, and it ranges from 0 to 14. On the pH scale, a pH of 7 is neutral, less than 7 is acidic and higher than 7 is basic.
