This was our second project in science, and it was all about matter! For our final project, we made a functional video game on Scratch. But before we look at that, let’s look at all the keystones that we had to do!

Keystone 1

For the first keystone, we learned about the physical and chemical properties of matter. We used a lot of math, which was unfortunate. The main assignment for this keystone was a guess who. We had to pick an object from around the classroom, find out its mass, measure its area and volume, and see if it was combustible or reactive with other chemicals. I chose a paper towel, and I said:

“Some basic physical properties of me include: I have a mass of 1.85g (quantitative observation), I have a volume of 20.14184 cm3 (quantitative observation), I have a density of 0.091848609 g/cm3 (quantitative observation). Some other physical observations are that I can be easily folded (qualitative observation), I am a very light brown in colour (qualitative observation) and I am extremely light (qualitative observation). One of my chemical properties is that I am EXTREMELY combustible when introduced to fire. What am I?”

This was a nice keystone because it was fairly easy to work on. It was also fun because we got to find an object around the class to use for our keystone.

Keystone 2

With our second keystone, we learned about the states of matter and the Kinetic Molecular Theory. The Kinetic Molecular Theory tells us that molecules are in constant motion, the more energy is added, the faster they move, and in between them there is empty space.

Another thing we learned was about diffusion and osmosis. Diffusion is where one type of particle mixes with another particle, an example of this would be smell.

For our assignment, we had to diffuse a gummy bear in different liquids and take observations.

As you can see, they grew quite a bit bigger than their original size. This is because the liquids diffused into the gummy bear and made them squishier and larger.

Unfortunately, two red gummy bears formed a mutiny against their friend, and by the time I got there, it was too late. RIP, red gummy bear, you will be missed.

Keystone 3

For our final keystone, we learned about how atoms are made up of proton, neutrons, and electrons. For our main assignment, we had to pitch an idea for a video game we would make on Scratch. This keystone was harder than it sounds. Because I have no idea how to code, I wasn’t sure what I could even do. I had a couple ideas, but because I didn’t know how to code, I wasn’t sure what I could do with Scratch. But, I came up with my idea: a game where you zoom in on water until you get very small.

Video Game

For making the video game, we used Scratch. Scratch was a little confusing at first, but after a while I got the hang of it, and my game works! This was the hardest part of the project for me. I have no idea how to code, but by clicking around on it, I was able to figure out how to use Scratch. Click this link to see it.

Alright, that’s pretty much it! Goodbye!
