Rube Goldberg Project

Our Rube Goldberg the “Boat Pop” is a Rube Goldberg that starts with a phone on a ramp and then the phone gets a call and vibrates down the ramp and hits the dominoes which hits the marbles then the marble rolls down a cut pool noodle on to a ramp of Popsicle sticks onto a boat with a needle attached at the end which is on a cardboard ramp and the boat slides down the ramp and pops the balloon.

Our three energy transfers are the phone hitting the dominoes(Potential to Kinetic), the marble sliding down the ramp(Potential to Gravitational) and finally the boat sliding and popping the balloon(Mechanical to Sound)

Science 10: Baby Making

My child has wavy hair, large eyes with short eyelashes, medium nose with round nostrils, and a long-thick mouth. He has ugly squiggly ears and thankfully thin eye brows and no uni-brow. He was born with a square chin, round face with 2 dimples, and no widows peak

A. It relates to the probability because of the probability, there’s a chance of the genes of the parents being different or the same, whether is be dominant of recessive. These probabilities of the traits of the baby is like real life because you can have same traits from your Dad and some from your Mom.

B. This simulation is accurate because you can differentiate the dominant and the recessive to decide which trait the child will have.

C. Yes I found some traits I would rather have than others, I feel this was common because all the traits were about appearance and we didn’t want our child to be”ugly” but I think that if it was a real child and you were a real parent you would love your child because there’s more than just appearance.

Float Your Boat: Sally

In this experiment we made an aluminium boat to see how many pennies it could hold, we got one piece of aluminium, two mini marshmallows, two tooth picks, one small strip of tape. Our boat held 95 pennies, We made sure no water leaked into our boat, and placed the pennies strategically. Our design was a bowl shape with two tooth picks crossing at the bottom, we use the marshmallows to help stick the tooth picks.

 

Hypothesis (If, then, because…)

If we make our aluminium boat then it will hold a couple hundred pennies because air that is in the boat will help it float .

Conclusion

My hypothesis was very over exaggerated because we didn’t even get one hundred pennies. As I was observing the boat while the pennies were being placed the boat was slowly crumpling and was being pushed into the water. As I was the penny placer I could feel the impact each penny was making as I was placing them down, I tried to put the dry pennies down because the less water on the pennies means that it will be lighter. For some reason something I notice was that the pennies weirdly smelt like vinegar to me. I feel having high walls on your boat really made the boat have a bigger weight capacity because most of the boats sank due to water flooding the boat, which made the boat sink.
