Last Friday class 2 and class 5 went to tamaki college  to  go to the science roadshow. When we got tamaki college then we line up waiting for someone to take us inside. Then a man came out and his name was sean and he was like 6 foot tall. Then he take us inside and we sat on the chris. Then she picked 3 volunteers and there names were Anthony, Iisa , and Emmy.

How does a musical instrument create sound?

1. Intro:

I am writing about how a guitar  instrument create sound.

2. Part of a guitar: A guitar is a instrument that has strings, notes, tone

and a sound hole and tuning keys.

3. How is sound created from a guitar? When you strum a guitar the sound goes into the hole and it bounces of the wood and come out of  hole and come out louder.

4. How to play a guitar: When you strum the guitar the strings vibrate.

5. Conclusion: I learn about guitar. I learn how to hold the guitar and how it vibrate and makes sound.

Funnel ears science experiment

Science experiment:

Question: What will happen to the sound if I change the shape of a piece of paper? (e.g. from a flat shape to a funnel shape)

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

Materials needed:

Experiment (procedure):

e.g. Step 1 - First hold a flat piece of paper against your ear. Block your other ear with your hand. Get your partner to speak to you. What is the sound like? Can you hear clearly?

Step 2 - Next, roll the piece of paper into a funnel shape. Put the funnel against your ear. Face the funnel towards your partner and listen to them speak. What does it sound like? Can you hear clearly?

Step 3 - Next, face the funnel to the side while your partner speaks to you. Does it make a difference to the sound that you can hear?

Step 4 - Put some cotton balls or tissue paper into the funnel to block one end. Does it make a difference to the sound you hear?

Step 5 - Next, roll the piece of paper up and l

Data (What happened?)

	Shape/object/materials	Results:
1	flat piece of paper	It sounded the same.
2	funnel facing to the front	It sounded a bit louder
3	funnel facing to the side	It sounded softer
4	cotton ball or tissue  blocking the narrow end of the funnel	It sounded softer than the one before
5	rolled up piece of paper (facing to the front)	It was louder and clearer
6	rolled up piece of paper (facing to the side)	It was not that clear.

Observations:

When I used a flat piece of paper it sounded the same. When I used the funnel facing to the front it sounded a bit louder. When I used funnel facing to the side it sounded softer. When I used cotton ball or tissue  blocking the narrow end of the funnel It sounded softer than the one before. When I rolled up piece of paper (facing to the front) it was louder and clearer. When I rolled up piece of paper (facing to the side)It was not that clear.

Conclusion:

l learned that when I use a funnel facing to the front it helps me to hear better. When it is facing to the side I can’t hear as well as before.
