Immersion Assembly

Omg, what a great start to term two. Immersion assembly was amazing. I loved how there was lots of excitement in the hall and seeing all my friends.

What is an immersion assembly you say? Well at our school every start of the term we have an “immersion assembly”. The teachers perform or show a movie of what they're team topic is about, and us, team 5, our topic is about ‘SOUND’!

I loved the costumes that they had on. The costumes were colourful. They also had funny wigs on. These were bright as well.

My favourite performance was team 5. I like their movie about sound. In the movie they had showed them playing instruments. They danced, it was so cool and funny. My highlights of being back to school is seeing my friends.

Grace-Science Experiment

Science experiment:

Question: What will happen to the sound if I cut the straw shorter and blow through it?

Hypothesis: (What do you think will happen?) e.g. I think that….

The sound will go up

Materials needed:

Straws & Scissors.

Experiment (procedure):

e.g. Step 1 - Crease straw

Step 2 - Cut crease into triangle shape with scissors. Blow air into cut end

Step 3 - Listen to the sound it makes, then record it.

Step 4 - Cut the straw shorter

Step 5 - Blow on cut end, then record it.

Data (What happened?)

15cm:	Makes a sound
10cm:	The sound went higher
5cm:	The sound went higher at 5cm than at 10cm

Observations:

First we each got a straw. Then we cut one end of the straw into a triangle form. At 15cm makes a little sound. Next at 10cm then sound went higher. The final time I had cut the straw the sound went higher at 5cm than at 10cm.

Conclusion:

My hypothesis was right because the sound went a little higher every time I cut the straw shorter.
