Research: Changing the color of flowers is very easy and simple. Flowers and plants normally drink water through their roots in the ground, but the stem will continue to drink water even when the roots are gone and provide it for the flowers and leaves. The reason that this happens is because of transpiration, transpiration is when water evaporating from the petals and leaves evaporates, which in turn pulls water from the roots, this process works similar to that of a straw. Dyeing the water just makes the movements of water throughout the plant visible, while at the same enhancing the flowers look.

Clean up: We can just throw away the materials when we are done

Looking back:
The results of our project were really good, everything that we thought was going to happen did happen. The flowers absorbed whatever color we put in the bottle blue, green, orange. My experiment turned out very, very well when we came back from break they were dead but still has a lot of color.
Looking beyond:
On a molecular level I noticed little splotches and dots on the flower only our after we put it in. A couple days later those tiny dots kept collecting and created colorful streaks on the flower.
Looking Inward:
I got very, very desirable results from our project everything we predicted to happen, happened. We put different colors in every plant and they all absorbed those colors. We tried making our experiment a little more trickier by cutting one of our flower stems down the middle and put each end into a different color food dye to see if it would turn half and half and yes it did work.
Looking Outward:
I worked with Nayeli and Marco on this project and I think we performed very well everyone had a very good understanding of the material we needed to know before doing the project, so I thought it was very helpful that they also did their own research.
Looking Forward:
If I could do this again I definitely would try to make it like tie dyed flower or just do something wild because this one was very simple.

Steps:
- cut the stems and prepare plants
- dye water
- put the plants inside
- wait
Materials:
- Flowers
- Water food coloring
- tube or flask
- knife
Hazards:
- knife, cutting stems
- thorns, roses have sharp thorns
Precautions:
- Gloves to prevents easy pricks or cuts
Clean up: We can just throw away the materials when we are done
