Echolocation Writing

ECHOLOCATION

Echolocation, also called bio sonar is used by several kinds of animals like bats and whales. Dolphins also use echolocation. Animals make sounds and listen to the echoes of those echoes that return from objects near them. They use these echoes to locate and identify the object

Ben Underwood could not see with his eyes but he could see by using sound. When sound rebounded off objects he knew where he was going. He could hear cars from far away and that would trigger sound waves. Ben Underwood used prosthetic (fake) eyes and he can skate, ride a bike and shoot a basketball inside a basketball hoop.

People who learn how to play and knows all of the moves they can go to the toumament at and you can also win the cup.

PIcture Of Reading Task

Kyal funnel ears Science experiment template

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)

Links to research about Sound:

http://www.thetech.org/exhibits/online/robotzoo/guide/bats_and_echoes.html

Hypothesis: (What do you think will happen?) e.g. I think that the sound will be louder or Echo

Materials needed:  Paper . Tape . Tissue . or . cotton .

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? Is the sound quality the same?

Step 5 - Next, roll the piece of paper up and face one end of the paper roll towards your partner. Listen to your partner speak. Is there a difference to the sound you hear?

Step 6 - Finally, turn to the side with your paper roll and listen to your partner speak. What is the sound like?

Data (What happened?)

	Shape/object/materials	Results:
1	flat piece of paper	didn’t make any difference.
2	funnel facing to the front	louder and sounds clearer
3	funnel facing to the  other side	person sounded quieter. background noise was louder
4	cotton ball or tissue  blocking the narrow end of the funnel	It will sound the same a bit, but it was a little bit quieter
5	rolled up piece of paper (facing to the front)	sounded a bit funny, but was clear.
6	rolled up piece of paper (facing to the other side)	couldn’t hear clearly. could hear lots of background noise

Observations: (This is your description of what happened)

When Miss Lagitupu put the funnel up to my ear she sounded louder.

When we used the flat piece of paper it didn’t make a difference. When we used the funnel the sound was louder and clearer. The sound was a bit quieter when the funnel was blocked.

Conclusion

My hypothesis was right because the sound was louder when the funnel was used.

KSET

Science experiment:

Question: What will happen to the sound if I cut the straw shorter?

Hypothesis: (What do you think will happen?) e.g. I think that the sound will go higher.

Materials needed:  Cut the straw shorter and cut it with a scissors

Experiment (procedure):

e.g. Step 1 - Take the straw and flatten the end 2-3cm making some sharp creases in the side.

Step 2 -  Then cut the straw into a triangle.

Step 3 -  Then when your finish you can blow on it.

Step 4 -  Then when you blow on it it will sound funny.

Step 5 -  Then if it make a  sound it is finish.

On the first day of school in Assembly all of teachers at Pt England showed us some equipment about stuff. Team 5 showed us about sound and showed us the movie. Team 1 is going to the zoo tomorrow to protect the animals and find out about things. Team 4 was giving out stuff.

This Term we are learning about sound.
