Rube Goldberg

I thought that Rube Goldberg was fun and frustrating

I think that Rube Goldberg was fun because you can never go to big and when you do it, it is does not work for most of the time and when you finally get it, it is super exciting. It was also fun for me because my Rube Goldberg took up my whole basement and it was hard to get in. Now that we took it down the basement is empty and looks so much bigger.

I thought that it was frustrating because eighty percent of the time it did not work and when we tested it, it worked all the way until the last step. It was also frustrating because it was super hard to get into the basement and every time you touch the ping pong table, it fell down and sadly did not work. When we got it to work it was the twenty sixth time.

In science we have been doing a project about plants. I will be telling you about my plants.

I will first tell you about my controlled plant.  My controlled plant looks healthy with only a few yellow leaves but mostly green. Today the biggest plant was 11cm and the smallest plant was 5 cm. On my controlled there are some big leaves which have a smooth feel and some small leaves which have a rough feel. My controlled has been growing slowly but it is ok. There  are little yellow flowers. It has grown pretty tall since the start.

My manipulated plant is dying slowly. The color is green with more yellow leaves than usual. The biggest plant is 8cm. The smallest plant is 5cm. The plant droops a lot. At the start it was doing well, until we added fertilizer. There are little yellow flowers. The are still little buds.

My controlled is doing well because it has the right amount of fertilizer My manipulated is probably not doing well because it does not the perfect amount of fertilizer.

In science we are doing a plant project. My group and I had to think of a question. When we thought of it we would do it on one of our plants. Our question was what would happen if we add fertilizer? We also made a hypothesis and mine was ‘’it might stop growing and the leaves will turn brown because once I spilled to much food in my fish tank and the two of the fish died, so maybe it would be the same for the plant.’’ There are two plants that we have, they are controlled and manipulated. Controlled has water, air, sunlight , soil and fertilizer. My manipulated one has everything but more fertilizer. So we are manipulating the soil.

After the first week I am noticing that the plants are growing and that they seem to be doing well. The color is green. The controlled is doing a bit better than the manipulated because it is more upright. The soil is very moist from watering it. There are some little leaves and some big. The bigger leaves are smooth and the small are ruff. I noticed that the manipulated is not looking great. I wonder why and if my prediction is right.

A maglev train is a train that levitates with magnets that repel. The train goes fast because it has less friction. The poles repel when north and north or south and south face each other.  For the track and train we put strip magnets on the train and the track.

What failed on Friday was the magnets were overlapping and that the magnets were in the wrong places. That kept the train from levitating.

My group is very helpful and nice when we were working. They were especially good at filling me in.
