I am very proud of how hard the students in 3/4E have been working. They did and excellent job of conducting an experiment and then writing a procedural writing piece based on the experiment. Here is an example of some of the writing:
Gravity
drop experiment
Aim:
How gravity effects objects falling from a chair.
Hypothesis:
I think all of the objects could take at least 40 milliseconds
or 1 second to fall.
Materials:
·
Golf ball
·
Down ball
·
2x paper (Flat and scrunched)
·
Pompom
·
Stopwatch
·
Soft soccer ball
·
Marble
Method:
1) First, step onto a chair.
2) And then, get a one meter
ruler.
3) After that, get one piece
of paper and scrunch it up so it is like a ball.
4) Now, drop the object of
your choice.
5) Then, as soon as the object
gets dropped you start the stopwatch.
6) Finally, press the ends
button on the stopwatch as soon as the object hits the ground and repeat this
with every object.

Conclusion:
There
were only 3 drops that took 1 second, also 3 different things that took 40
milliseconds and the times were 1.47, 1.35, 1.49 and the 40 milliseconds were
46ml, 48ml and 43 milliseconds.

We are looking forward to the rest of the term and are excited for book week and The Cardboard challenge.
