Salt Crystal

Today in Science, we’re starting to make some salt crystals.

  1. We have created a “SUPER SATURATED SOLUTION“. A normal saturated solution is where there is a solution, like water, at room temperature with the maximum amount of salt dissolved into it, but a SUPER SATURATED SOLUTION is where the solution is heated up and able to have more salt dissolved into it.
  2. We were instructed to form groups of two or three, and I paired up with my good friend Andrew.
  3. Then we got a paper clip and straightened it out and tied a piece of string to it, which will be where the salt crystals grow.
  4. We got a tube and put the SUPER SATURATED SOLUTION into it and dyed it blue.

I will update this when the crystals grow.

UPDATE:

NOOOO

Our (Andrews and mine) salt crystals didn’t grow!!!

We also got to use some microscopes. Here’s a diagram of one

Wavy Water

We are learning about the water cycle in science right now, and here are the different types of precipitation and the water cycle

Evaporation is where the sun, or a heat source, heats up the water and turns it into water vapour. Then it condensates and turns into a visible gas, a cloud. Precipitation is when the cloud holds enough water that it starts letting it out, making it rain. It then might go into a river or lake, and it flows back into the ocean.

Invention

In JSCI we were tasked to design an invention. an invention is a device made by a person to help with a problem.

it has microscopic fans to cool down the wearer and it has a USB-C charger port. I thought of this because as you know Oodies are really comfy but you always overheat in them so this cools you down in it I call it Coolies.

Recap of Term 1 Paper Plane Experiment

Last term in JSCI we learned about the Scientific Method. We also did an experiment with paper planes, me and my friend Ryle measured how long they glided for. To make it fair I got three paper planes that were from 3 different creators and are said to be really good at gliding. The way we measured was by throwing the planes with the same force (roughly), and seeing how long they glided for with the stopwatch.

Plane 1 Results: 1: 3.50    2: 0.78    3: 0.82    Average: 2.29

Plane 2 Results: 1: 1.60    2: 1.16    3: 2.9       Average: 1.886666667

Plane 3 Results: 1: 0.56    2: 2.22   3: 0.53    Average: 1.103333333

 

ZMR Science: Paper Plane Challenge

today in science we are making two paper air planes and seeing which one goes further. I have two videos so you can make these yourself as well. I will just be using basic A4 paper for the paper air planes. I will 1: make the planes 2: test them in the lane way 3: count how many steps each one went 4: do it a few more times each 5: collect the data and get a rough average. 6: see which one went further. also I got the two videos from the same guy and made sure they both said they would go the same length to make it fair.

P1:

P2:

I think that P1 will fly further as it looks more aerodynamic.

P1: 36

P1: T1 – 14

P1: T2 – 12

P1: T3 – 10

P1: average ~12

P2: 46

P2: T1 – 18

P2: T2 – 16

P2: T3 – 12

P2: average ~15

P2 got the furthest the reason is because P2 had a longer wingspan so it can sit on the wind a lot better, but P1 was more straight and had a shorter wingspan so it couldn’t glide as more.
