Atoms are the smallest building blocks of matter and molecules are two or more atoms connected together.
Today in class we investigated a drop of water and examining it on a molecular level.
Watch the video of a water balloon popping in slow motion and write a comment answering the question:
Why do you think the water keeps its shape the moment the balloon is popped?
The water stayed together because the water molecules are attracted to each other.
ReplyDeleteI think that the water in the balloon kept it's shape when it was first popped because, the molecules were so attracted to each other. Also the balloon had shaped the water, so that for a few split seconds,the water was able to stay in the shape of the balloon. Also today in class, when the water came out of the dropper it kept it's shape as it landed on the wax paper, I think the same thing happened to the balloon.
ReplyDeleteI think the water keeps it shape when the balloon pops because even though the water molecules are always moving they still stay together. Like today in our experiment with the water droppers the water kept its form when it hit the wax paper.

ReplyDeleteThe water keeps its shape the moment the balloon is popped. This is because the composition of the water molecules is two hydrogen atoms, and one oxygen atom. The hydrogen atoms contain one proton that is positively charged, making the hydrogen atoms positively charged, which is attracted the negatively charged oxygen atom. This attraction, or bond, is called the hydrogen bond, which is a chemical bond. A rather weak bond, but it is present. This attracts the water molecules inside the water and causes the water molecules to stay together a moment after the balloon is popped, though after a few second the molecules and pulled from each other by the force of earths gravity, which is 9.807 metres per second squared.
I think that the water in the balloon kept its shape because the molecules were attracted to each other and they were so connected that they couldn't separate until they hit something solid. By Karina PatEl
ReplyDeleteI think the water keeps its shape the moment the balloon is popped because of the atoms and molecules in a liquid,(the water in this case) have a strong attraction. That makes the atoms and molecules stay pretty close together and makes the water keep its shape the moment the balloon pops.
ReplyDeleteI think that the water still holds it's shape even when the balloon is popped is because the water molecules are very strongly attracted to each other. This way, even when the water is moving, the molecules stay connected.
ReplyDeleteI think the water keeps it shape because the water molecules wanted to stay together. We learned why and how in class. They are attracted to each other like magnets.
ReplyDeleteHomework Question:
ReplyDeleteThe water kept it's shape the moment when the balloon popped because the movement of popping the balloon was so sudden that the water molecules stayed together in the shape it was in the balloon.
homework question
ReplyDeleteI think that the water kept its shape because the balloon popped so fast that the water maintained its shape as the balloon popped
Great thinking about water molecules!
ReplyDeleteThe water stayed together because the molecules in the water are attracted to each other.
ReplyDeleteThe molecules are trying to stick together. In Solids the molecules are packed tightly together. In liquids they move a little bit around because they have more space but they are trying to stay together. In a gas they have plenty of space but they are still trying to stick together. When It is hot the molecules move around faster. When it is cold the molecules slow down. If the video continued to show the water balloon drop to the ground you can still see the water is connected. Lets say that you leave a glass of water outside when its freezing out. The molecules will slow down until they turn into ice or a solid. When it gets warmer out the molecules move around and transform into a liquid in this case water. Lets say its extremely hot out the next day. The molecules will speed up and turn into a gas. This process can go on forever. This is why solids are harder to break than liquids or gasses.
ReplyDeleteThe water molecules help its shape because they were attracted to each other.
ReplyDeleteThe water stayed together pretty well because the water molecules are attracted to each other so they stay tightly packed together.
ReplyDeleteThe molecules in the balloon stick tightly together because they are suck it that certain area. Once the balloon is popped the water stays because the molecules still stick closely together.
