Rube Goldberg How I Think Building is Going to Go

So first off, I think that it will be hard because well I’m working alone so I will have to do all the work and setting up and measuring etc, also building will take longer because it is only me setting this whole thing up. Second I think that it will be easier in some ways like I wont have to decide who will do what and this person wanted to do that etc. Also if someone got sick then what would what we do but lucky for me I don’t have to decide that because I don’t have a partner/s. But if it doesn’t work the  first time (which I don’t think it will work on the first time) I will have to set it up all over again. Well now you know the ups and downs of building alone that I think will happen while I’m working on building the machine in the future.

Rube Goldberg Designing the Machine

So I thought originally to ring a bell as the thing I wanted to accomplish for my Rube Goldberg, but then I thought wait could I do something more practical. This was a challenge because there was not a wide variety of things to choose from what I was thinking of so I came up with the idea of getting a ball into a bin. My bins are going to be rectangular baskets and best of all I can use most of the same steps that I was going to use for my first idea and it also has the same amount of steps which is good because the minimum is 8 steps but I have more, that is good so I don’t have to think of a whole different plan. The process required a lot of research, I spent a couple hours after school one day. So basically I had to make some changes to the original and some challenges occurred and the process was hard.

3rd week Lima beans

No air                                                                                No sunlight                                                                          controlled

No Air

2 of the plants exploded I think its because we are not giving  those plants carbon dioxide.

No sunlight

It is tall but sick because we gave that plant no sunlight so it cant feed itself and smells like stinky socks and its pale. You may  think since it’s tall it’s a little bit healthy. However, it’s not healthy, it’s tall because it’s looking for the sunlight.

controlled

It is tall and healthy because we gave that plant sunlight, carbon dioxide, and water.

 

Plants can grow with out  soil its called “hydroponics.”

Seed pods

What’s happening now.

My plants are starting to lose their leaves and the pistols are starting to grow seeds inside.  We have been observing our plants for over 10 days, maybe even 20 and we pollinated our flowers with q-tips.  We rubbed our q-tip on the stamen of a flower and put the pollen that was on the q-tip on to a pistil of another flower.  That is how we pollinated in class because there are no bees or humming birds or wild animals to pollinate the flowers.

Prediction.

I think in a few days that all of the flowers will have fallen off and some of the pistols will be breaking open and dropping seeds.

Growth.

My plant started out as just a teeny seed.  Then it just sprouted and grew a stem and then some leaves.  But then a big change happened.  The plant grew taller and started growing leaves.  We pollinated the flower of the plant.  After this the pistils started getting fat with seeds in them.  I am excited to see what is going to happen next.

 

week 1 plant

We are observing our first  plant  observation.

My plants are  just starting to  sprout , there’s a lot of  excitement in the first week.

Grown a lot since I planted my  seeds.

I put up lot of hard work into this I’m proud of how my plant has grown and it’s really fun.  I wonder how much more it will grow.

Week 2 Plants

       We started week 2 of our plant observation unit. Our  controlled plants show cell 1 my plant is 7 centimeters tall in cell 2 my plant is 5 centimeters tall, and in cell 3 one of my plants are 3 centimeters tall. The other one is 5 Centimeters. In cell 4 my plant is 8 centimeters tall. My manipulative no plants have grown yet. I’m excited to see what’s going to happen and if they’re going to grow or not.
