Rube Goldberg Project

rosef2016 on

My Rube Goldberg project is named the effortless bell. The machine starts with a marble being pushed off higher ground onto a ramp. At the bottom of the ramp there are a line of dominoes which are triggered by the marble, which then hit another, larger marble that falls off a ledge into one side of a scale, which falls onto a bell and rings it.

There are three different energies used in this machine, potential, kinetic and gravitational. It starts with potential because it is about to fall from the first ledge onto the ramp, where it changes to kinetic because it begins to move quickly. When it falls into the scale and causes the other side of the scale to go up because of the weight on the other end, it is gravitational.

Baby Project – Science

My child has a round shaped head and medium sized facial features. He has brown eyes and hair. His eyebrows are bushy and his hair is wavy. His ears are Darwin pointed and he has freckles all over his face. He’s got long eyelashes as well.

The coin flip relates to the probability of genetics being passed down because what is given from each parent is completely random, as was the coin flip.

It does not represent real life accurately however, because if both parents have brown hair and their child somehow has red hair, and there is no trace of red hair in their ancestry, it’s impossible to inherit that. A coin flip has nothing to do with the parents so the child could have red hair regardless.

I found some preferences that I had based on where I was raised. I liked that my child had freckles and long eyelashes, which are considered nice in Canada because they give a more feminine and childish look. Here, youth is considered beautiful, so having characteristics that keep you looking young are nice. He also had fuller lips which was a preference as to having very thin lips. Many beauty and lip products advertise full lips only, so that’s the ideal image for us.

Float Your Boat Activity

In the experiment, we were challenged to create a boat that could withstand weight being put in it using only aluminum foil, two marshmallows, two toothpicks, and a strip of masking tape.

Our hypothesis was if we put a strip of masking tape underneath the boat, then the boat would stay afloat, because it would stop the boat from caving in from the weight of the pennies put in it.

In conclusion, our boat did pretty well. It held 45 pennies before sinking. Our hypothesis was supported because the tape did keep the bottom of the boat sturdy. Our boat, sadboat, had many pennies put in the middle of the boat because we knew the middle was the most safe because of the tape. In the end, our boat sank because of the corners not being strong enough, so the middle of the boat was the strongest point. An error that could’ve been made would be the shape and amount of marshmallows put on each side of the boat. The shape because it was not a perfect rectangle, the corner and sides were wonky, and the amount of marshmallows for each side was uneven which could have affected the stability of the boat. To improve our boat, we would have four full marshmallows for each side and more tape to cover the entire bottom of the boat.
