One of our activities this week was to create a Popplet or word web to increase our range of vocabulary. The word we were given was accomplish. I found 28 words that are synonyms for accomplish.

For inquiry this term we are studying sound which is what we hear all around on a daily basis. Have you ever wondered what sound is? Well, this explanation will explain everything about sound and how it works.
The scientific process of sound begins once a material is hit, that material begins to vibrate. Sound travels through the sound wave in a high tone or a low tone. Depending on the pitch. The vibration continues to travel until it reaches your eardrum and sends a signal to the brain. Your brain then transfers it into a recognized sound. Sound initially starts from when an object is loudly hit but sometimes sound begins from power. If you turn on something from the plug like a speaker and it plays music, then the noise didn’t start from you hitting the material.
What would you think if there was no such thing as sound? Well I think that it would be really boring but simultaneously difficult because if you were trying to communicate with the person next to you, you wouldn’t be able to hear them. Instead, you would have to text, write on a piece of paper or use sign language subsequently if there was such thing as sound and there is, you could just talk to them.
You could conduct sound experiments to help increase your knowledge about how sound works. For example, the whispering cups experiment. You could find three different types of strings and test out which string would be best of use to be able to hear the other person's voice from your cup.

Name: Quziyah & Mua:)
Title of experiment: Talking Cups Experiment.
Question: (What do we want to find out?)
We want to find out if we could hear each other from far just by using cups, a small string, a small rope and a thicker string.
Hypothesis: (What do you think will happen?)
We think that we will be able to hear better with the plastic string because when we first used the thin string, we couldn’t hear each other clearly. Since we couldn’t hear our voices properly, we think that the thicker the string gets, the better you can hear the other persons voice.
Procedure: (How will we find out? (Step by step)
First we were given three strings, two pins, two cups and also two ice blocks sticks. After collecting all of the equipment we needed to poke a small hole at the bottom of each cup that will be big enough to fit a very thin string into it. Next we concentrated to put the string through the hole and tie the string to the ice block stick. Adventually we got it through without a struggle. After that we went outside and tested it out. We couldn’t really hear each others voices by speaking into the cup so we changed the string and attached a thicker string which was a rope. We did the same thing we did to the thinner string and tested it out. This time we could hear each others voices clearer. My partner and I were onto the last string.
Results: (What actually happened?)
After following the instructions, we found out that we could hear better with the wool rope. We think that the reason for this is because the voice goes throw
Conclusions: (What did we learn?)
We learned that the vibrations travel through the string into the other side of the cup making the other person able to hear their voice. We also learned that you have to pull the string tight enough because if it’s crooked then the vibration won’t be able to travel.
