Science Word Problem Solving Steps : Science Word Problem Solving Steps Step-by-Step Procedure to Solve algebraic Science Problems
Problem Example : Problem Example Here is a typical word problem based on a familiar concept.
What is the area of a surface that is 2 meters long and 1.5 meters wide?
Step One : Step One From the problem, list what you already know (the knowns). Include variable, number and unit for each term.
In this example, what is given?
Length = 2 meters
Width = 1.5 meters
Knowns: l = 2m w = 1.5m
Step Two : Step Two List what you are solving for as “?” and a unit (unknown).
We are calculating area in this example.
Unknown: Area = ? square meters
Unknown: A = ? m2
Step Three : Step Three What formula do we need for this problem?
Write the appropriate formula based upon knowns and unknown
In this example, the formula we need is Area = Length x width
A = lw
Step Four (if needed) : Step Four (if needed) Rewrite the formula to solve it for the unknown, if necessary.
The example doesn’t need rewritten. We are already solving for area.
If the unknown was length, we would rewrite the formula, solving for length
l = A/w
Step Five : Step Five Put the knowns (numbers and units) in formula
For this example A = (2m)(1.5m)
Step Six : Step Six Solve the formula, including units with the answer
For the example Area = 3.0 m2
A = 3.0m2
Slide 9 : This method works for most of the numeric science problems you will encounter, especially ones which involve applying formulas to equations.
