Hello! It’s been a while since I’ve updated about my technology experience. This term my group (1), is now in steam class! For the first week, we looked at something very intriguing, the Scientific Method. Here is a diagram I took online to give you an idea of what a scientific method could be.
Storm in a Jar
In that same week, we looked through a project called “Storm in a Jar”. Obviously, there’s not a literal storm trapped In a jar, but the name comes from its appearance when the experiment is completed.
This science experiment is quite simple, it involves; water, shaving cream, two jars, and food colouring (any colour).
Get a jar, then fill it up halfway with water. This can be Jar A. Next, coat the top of the water from jar A, with shaving cream—that’ll play as our cloud to support the term “storm”, you’ll see soon.
Take your separate jar and fill it halfway with water. We will call this jar B. Pour a bit of food dye inside jar B, then stir it. After a good stir, take a table spoon of jar B’s liquid and pour it on top of jar A on the shaving cream.
The food dye liquid should be able to break through the shaving cream, and create the illusion of a storm in a jar. Cool, right? Completely harmless too, just don’t try drinking it…
Robot Frogs
For the other few weeks of tech, we’re focused on a quite interesting topic—The Study of Robots. Our project is a robotic frog, there’s no grouping in this project, we’re supposed to make one ourselves!
The robotic frog, not what you think it is—-yeah I know what your thinking, its not some flashy metal robot frog, but really, it’s basically just cardboard that jumps, powered by batteries and a rubber band–yet I see where ‘frog’ comes from because the cardboard is almost shaped like a frog.
This project includes:
Cardboard, Batteries, A motor, Skewers, rubber band, and Popsicle sticks.
Measure 14 CM and 7cm to make a triangle. Draw exactly 4 triangles then cut them ou
t.
Use the same measurements to make a rectangle and cut it out. Next, get a glue stick, or any cylinder so you can trace it on cardboard and make three perfect circles—cut those out.
With your triangles, poke a hole near each corner, do this with all your four triangles. Then get your circles and poke a hole in the centre of each of them.
Now with the rest, I’m not sure what happens next because we haven’t finished our project, but I’m sure the following bits include hot glue, if you’re interested, the video is in this link!

That’s basically all I can recall from tech, if you have many questions, dump them all in the comments, I’ll try my best to reply to them.
Thank you for reading, have an amazing day.
