Scientific Method
Observe: Find something in the world that you wonder how it works.
Question: Develop questions about the thing you are wondering about (who, what, where, when, why, how)
Hypothesize: Develop a prediction to how it works; "If I do this, then that will happen..."
Experiment: Develop a way to test your hypothesis
Analysis: Question the results of your experiment; what happened, why, where, when, how?
Conclusion: Explain to others, what the thing is that we questioned. What our hypothesis was and how we tested it. What our results were and why they matter.
Independent Variables: is changed during the experiment
Dependent Variables: is measured during the experiment
Controlled Variables: stays the same during the experiment
Experiment: Flying Rockets!
Materials:
-
2x paper
-
Scissors
-
Pencil
-
Drinking Straw
-
Ruler
-
Measuring Tape
1) Cut one piece of paper into four smaller rectangles, by cutting it
in half lengthwise and widthwise. This will allow you to make four
rockets
2) Wrap one of the paper rectangles around a pencil to form a
cylinder, with the long edge of the paper along the length of the
pencil
Procedure:
3) Tape the cylinder closed so it does not unravel (don't tape it to the pencil)
4) Slide the cylinder off the pencil. Pinch
one end of the cylinder shut and seal it
with tape (this is the front end of your
rocket). Leave the other end open. This
will be your first rocket, with no fins
5) With plenty of room in front of you - no
obstructions - prepare to launch your first
rocket. Slide it over a drinking straw. Aim the
straw forward, then blow into it as hard as
you can. watch as it flies.
Record distance and flight pattern
6) Repeat launch sequence x3 and record the average.
Make another rocket with fins (4 triangles spread on
the end of the rocket.
Record differences in distance and flight pattern
