Greenhouse measurement and modelling


No, the greenhouse isn't planning to become a supermodel. We are going to work out how to accurately measure it and draw up scale model diagrams of it.
Does anyone know how to do wany of that? What do you think you have to be able to do...?
Once we have successfully worked it out and drawn it in our maths books, fast finishers can use google sketchup to create a 3D drawing of it.
The basic shape is similar to the one pictured above. The dimensions and proportions are bigger.

I know how to draw up a scale its pimple simple really, and i cant wait to start it's nice to know we can actaully start this!!!
ashy mashy
peace out

ohh i think you might of thought i might have just been rude by saying we can actaully get started but i was being happy!!!(i'm excited)
ashy mashy
peace out!!!

So what's the formula for working out the area of a roundy half circle 3D shape? And what's the real name for it?
And yes, it did sound rude, so thank you for clarifying, MissMashy.I appreciate it. :-)
We will start measuring tomorrow

I think that it will be a challenge measuring the greenhouse in height ways. We will probably need some ladders or something.
I do not know the formula for a roundy half circle 3D shape Mr Woody but I do know that the formula for a full circle is pi(3.14159.....)multiplied by r2 (radii) It will be cool making a exact scaled copy of the Greenhouse on Google Sketch-Up. I know that there is Sketch-Up talent in this class!!! I think that we need people to actually pay attention in this section in this part of the project. I think the reason why out of 51 votes 14 people (27%) voted no on No Thanks is because some people don't want to be bossed around and ordered around to do things by one or two people so thats why there pulling out.
I really can't wait to start measuring and working things out.
It's all about Geometry and Measuring.
I think that we will need to be switched on tomorrow.

And Mr Woody do we have groups and what will we be doing in them?

And remember we are not also doing this for fun, we are learning new things every step of the way.
We are also developing research skills and we are starting to really pitch in as a team of Room5ians!!!!

On Tuesday I watched the new tv show what's in my food and I have gathered info and put it onto my blog.
And remember to try and comment on all of the latest posts like the Spongebob one and the Thought one.
I really appreciate your feedback!!!!

HEYA!
I agree with you hamiltron, people are pulling out because some people will not be heard and some people will always take charge and tell everyone what to do.
Volume of Greenhouse:
area of end wall x length of house.
Area of end wall:
height of rectangle x width of rectangle + area of semicircle i.e. half pi x radius squared.
Area rectangle: 10 x 5: 50mL
Area semicircle: 5 x pi x 5L= 39mL
Total: 89mL
50: Volume: 89 x 10= 890m3
I don't really get all this but my dad wrote it down on a piece of paper so I wrote it down here.
If any of you understand, please tell me.
My reference is my Dad!

You are not alone kerli! We did all the ruling and so on today. And, Hamiltron, you do like 5 comments at the same time!

Wow, Kerli! You've done well! I don't know what to say because I havn't been at school. (I am really sick lately) and I've been trying to keep up on the blog.

Mushroom Shortie said...

Those formula's are cool for working out the volume, but wont that give us the solid volume, like the capacity of the 3D shape?
We need the surface area of the curve. A volume of an object measures how much space it takes up. How will we know how much fabric/plastic or whatever we need for the curve? I think we need to work out the surface area.I think it might be - 1/2PiR squared X Length.
It's a semi-circlular prism. We are finding the surface area of a semi-circular prism.

Thanks to my Mum and my brother for this fine comment :D

***Not including the surface area of the base***

Sorry to be off topic but, mushroom shortie, who are you exactly??? Tell me when I get to school - as long as you know who I am!! (Are you in Room 5 this year or last year?!)

Anyway, I am not a maths genius so I have absolutely no idea how to do any of that stuff!!!

Mushroom Shortie said...

Mudpies, I'm Marz Barz.

If you want to measure the roundness of the half cylinder thing couldn't you just put a rope over the top of it and put that up to a tape measure. -_-

Er, No Chicken Feety. Then you'd have already built it!

Sorry to be off topic, but Mr. Woody, can you please check out this website me and my mum found?
It's called SchoolTube and It's for students and teachers!
