STEM Workshop Term 3 Week 3

STEM Reflection

This week, my STEM workshop was about Vortex Cannons. The first thing we talked about was the 3 states of matter. The 3 states of matter are Solid, Liquid and Gas. An example of a Solid is like a cube where the atoms are closer together. A liquid is like water or juice where the atoms are a little bit apart meaning that when you pour water into a jug, it will take the capacity of that jug. But when you pour water into an open area, it will spill everywhere because the atoms are a more apart. And the last one is Gas. Gas is when the atoms are way more apart. Gas also goes up and the type of gases are, carbon dioxide, air or oxygen and when water evaporates from the heat, that's also gas too.

Our task was to make a smaller Vortex Cannon using a half plastic bottle, a balloon and some tape. Because the bottle was already cut into half, all we had to do was to cut a little bit of the balloon then put it around the plastic bottle. Then to make the balloon stay, you put the tape around the balloon.

This is what a vortex cannon looks like:

On Tuesday this week, my whanau class did a STEM workshop. STEM stands for science, technology, engineering and maths. Our workshop was a challenge and that challenge was to make the the tallest tower. For our tower, we needed to make it tall but to also make it stable or it won't stand up properly. The tower also had to hold a golf ball for 2 minutes long. The equipments were, 50 straws, 50 pipe cleaners and 25 paper clips. In my group, I had Erin, Mila and Sara and we won with a 22cm tower. Here is a picture of our winning tower:

This week I have been learning waterline with Adrienne. She taught us how we must save our precious water because we only 1% of water to use. Out of 100%, 97% is to salty for us, 2% is -  we can't get because it is underground or it is frozen, so only 1% is fresh for us to drink. What I really found interesting is how we get condensation on our windows. At night when we sleep, we breath and sometimes snore and the water vapor comes out from our mouth and touches the window. Then the gas turns into water. I also learned that one oxygen and two hydrogens makes one very, very small water drop. this is called a water molucule. I found this fun and interesting.
I also did talent time on Friday. I was in Room 2 making an apron. I found it very fun and I learned how to make it. But what I found very hard was to put the string into the hole of the needle. But luckily for me I had a big hole.
