Today was day 1 for Noah and I to start on our Magnetic silly putty that we researched just yesterday. We were going to ask for Black Iron Oxide because Andrew said he did but today he said he was just regular Iron Oxide so it didn't work out. He said that he could order it but we could get more points for making it ourselves. Andrew said he knew how to make the magnetite so we followed his instructions and did it with him. I dont have the instructions written down since we just did what Andrew said but I remember what we did.
1. Pour the PCB Etchant (ferric chloride) into a small beaker and add water. 2. Place a piece of steel wool into the beaker and stir it using a glass stirring rod. 3. Crush the steel wool to break it up while stirring. 4. Stop when the solution turns bright green The way that Andrew instructed us was completely wrong. And it began to rust almost immediately.

I got really afraid that I wasn't going to get enough points so I did as many worksheets as i could!!
Today me and my partner Kobe, decided to switch project ideas in another direction because we just had NO luck finding the parts we needed for the Lava Lamp.We decided on glowing water. Hopedully this turns out the way we imagine!
Some questions we had were:
Today I brought in food coloring and Kobe and I talked about what colors we wanted and what different kinds of ink from sharpies we wanted too.
Dry Ice Lab:
Today in class we had the opportunity to experiment with dry ice. We got to do whatever we wanted for the most part as long as we were safe. My group put dry ice in water, both cold and warm, measured the diameter of the dry ice till it was 1 cm and put it in a sphere balloon and measured the diameter and put the balloon in water. Looking Back: What happened?
Today I made another mini project which was creating an Oobleck Stress Ball. This was a simple project but very messy and full of laughs. Since I had missed school the day before because I was sick, I tried to catch up and get more points by doing another mini project. All I needed for this was some cornstarch, water, a couple balloons,a funnel and something to make the oobleck in a bowl. I started off just making the oobleck into the bowl like normal, only I knew just how i wanted mine to be because everybody else seemed too watery so I wanted to add less water and more cornstarch. After mixing the powder and the water to the consistency I wanted, I then started to grab the oobleck with my hands and carry it into the funnel that was attached to the balloon. The oobleck was going in fine until the balloon was getting full and wouldn't stretch. I decided i needed to do something about it, so i washed the top of the balloon after removing the funnel and blew into it so that there would be space for the rest of the oobleck and it eventually got in. I had to do that a couple of times, and I do wish that I had some more cornstarch so I could get it just a little thicker and ever have some more oobleck to out into the balloon. Anyway, after I tied the balloon and put it in another balloon and tied that one too, so that way the likelihood of it leaking or breaking is much smaller.
In class my partner and I discussed what ideas for projects we wanted to try. I found it extremely difficult to find project ideas that weren't so elementary.
