Kia Ora Everybody! This Term we have a new subject which is Science! At the start of Term 3, our first experiment, it's called "Hokey Pokey". The thing is I'm not there on that day when they did the experiment, because I was in "ESOL", stands for English Speaking of Other Lauguages.
But for a change, I attended last week (Just on last week Tuesday) science second experiments it's called "Red Cabbage Indicator".
For those who don't know it, here's a video that might help you:
(This is similar to what are we doing)
This is the materials/recipe that we used in Science to make to make this colorful indicator:
Bunsen Burner, Tripod (Not the one that you to stand a camera), 6 test tubes, mat, glass rod, red cabbage an cut it into pieces, beaker at least 200ml, wire gauze, Funnel, water, shampoo, florclean, lemonade, toilet cleaner, toothpaste, sodioum hydrox.
Step One: We set up the mat then put the bunsen burner and set it up, next put the tripod above the bunsen burner. Place the metal map above the tripod and finally put the wire gauze before the beaker at the top. Set it up like this:
(We take the photo while letting the red cabbage boil)
Step Two: We put water inside the beaker at least 100ml of water, then we put the red cabbage at least 100ml, then we turn on the bunsen burner into blue flame (Blue flame is very hot) as you can in the pics, there's no flame at all, but trust me there's a flame. The reason why you can't see it because the light was on so yeah.
Step 3: At first you need to mix it with the glass stick, it will turn into light blue then to dark blue. The more you mix it, the more it will turn darker. Just let it boil in a few minutes. At the start of it, you will see tiny bubbles on the edge or in the middle. That means it's starting to boil.
Step 4: After a few minutes later it's starting to boil like crazy, you need to turn off the bunsen burner, (You need a brave person to turn it off). Now we need our funnel, put the funnel at the top of one test tube. Then let the red cabbage cooler in a couple of minutes. After that pour the red cabbage to one of the test tubes, do the same to other test tubes.
After that put each test tubes this thing: shampoo, florclean, lemonade, toilet cleaner, toothpaste, sodioum hydrox. It's doesn't matter which test tubes you put those things in.
This is the result of our Experiment:
Reflection: It was pretty, but there's still a room for improvement.
Bye see yah!
