Ever wonder?
Why do we salt the roads in the winter?
Lets find out using the scientific method
Step one of the scientific method is ask a question
The question for this experiment is, why do we put salt on the roads in the winter?
Step two, do research.
From my research I learned that salt lowers the freezing point of water.
The next step is state a hypothesis.
By using our research we can make the hypothesis that the ice will melt faster in salt than by itself
Step four, conduct the experiment.
for the experiment we use two bowls. In one bowl we add salt and the other we leave empty then we added the ice cubes to both bowls at the same time.
Next, we set a timer for thirty minutes.
Step five, analyze the results.
When the timer is up, we check our ice cubes.
We place them on a paper towel to get a better look.
We notice that the ice cube that was in salt is smaller than the ice cube that was by itself.
Thus, the ice in the salt melted faster than the ice by itself.
Step six, conclusion.
We concluded that the ice with the salt melted faster than the ice by itself because the salt caused the freezing point of the ice to lower which means our hypothesis was correct.
Lets try the scientific method with a different experiment using m&ms and water.
First we ask the question, Do skittles dissolve faster in warm or cool water?
The next step is to do our research.
After doing research we can state our hypothesis.
The next step is to conduct our experiment.
Fill one bowl with warm water.
And fill the other with room temperature water.
Next add your two M&Ms at the same time.
Then set your timer for three minutes.
Step five, analyze the results.
When the timer goes off, check your M&Ms.
Notice you can see more chocolate on the one in the warm water than the one in the room temperature water.
Finally, make your conclusion, was you hypothesis correct?
Now lets review all six steps.
Step one, ask a question that your experiment will be based upon.
Step two, do research.
Step three, state a hypothesis.
Step four, conduct the experiment.
Step five, analyze the results.
And step six, the conclusion
Here is an easy way to remember the six steps of the scientific method.
People really hate eating donuts and cider.
People is for step one, ask a question. Or in other words, whats the problem?
Really is for research.
Hate is for step three hypothesis.
Eating is for step four, experiment.
And is for step five analyze the results.
And cider is for step six the conclusion.
