What an exciting term it has been so far! The students in 3/4E have really enjoyed working through the Discovery unit in inquiry. They have had a great time experimenting and making new discoveries. This group was hard at work planning their "Raft Challenge".



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.


Results:

Objects:
Time 1
Time 2
Time 3
Golf ball
99 ml
57ml
48ml
Down ball
38ml
43ml
55ml
Paper
1.47
1.35
1.49
Pompom
31ml
58ml
55ml
Soft soccer ball
34ml
74ml
73ml
Scrunched paper
34ml
64ml
72ml
Marble
60ml
46ml
57ml

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.
