New science project

During the week end for science we had to make a 3 dimensional miniature garden That we sprayed of different type of solution to grow some colored crystals on Tuesday.
day 2
I chose to add some more crystal  on the grasses with a green salt solution and on the trees with a pink gorax solution and finally poot some blue sugar solution in the river.
Day 3
Incredible!!The Salt Crystal climbed up some of the tooth pics and the borax crystals on the cotton tree began to grow with some litle sprakles !!!!!!!!
Day 5
Nothing had changed during the weekend
2 weeks later
 I realized sadly that my crystals had stopped growing


                                          This is my garden (didn't work very well)

 What did the chrystal grow the best on?
I think that it grows the best sponges. I think so because all the best gardens had a crystal in it. And I think sponges have this effect because they absorbe the solution.

What did the christal grow the worste on?
For me and oher people the crystal grow worste on coton .It did like coton sugar when we poot it in our mouth , it bicame small and hard and impossible to grow crystale on.

What solution was the hardest /easiest to grow crystal ?
Looking at all of our projects the easiest and fastest solution to grow srystals were borax ,salt and solfate . I also think that sugar and phosphate were the hardest and slowest solutions to grow cystals.


Conclusion
This experiment teach me a lot of things because some of my crystals succeed to grow but some didn't ,but I also watch others crystal garden and it's how I figured out the answer to the main question: How does crystal grow? I think that what happens is that first crystal need to be poot on an absorbing substance after slowly the liquide part of the solution will evaporate letting the solide part of the solution grow slowly finally forming crystal.

  1. Be sure that you include the various questions to the Data Analysis section, answer the guiding question and include a further inquiry. You may check Clare's and Hannah's for a good idea.
