I see 

a red Jelly fish 

And a mass of red yellow and blue 

And when the yellow and blue mix it change in to green

What would happen if We added dishwashing liquid to the exsperamint

I think that there would be a ceemicol reaction when you put the dishwashing liquid.

I wonder if it matters what food colouring you yse to put in the experiment 

I wounder if it depends what dishwashing liquid you use to get the same ruzoalta?

I think that the jelly beens will dye the worm water.
What will happen when we add vinegar?
I think that the jelly beens will dazove.

I see I see  the colour draneing from the jelly beens.
I think I think that the jelly beens will change to a white colour because the colour is drained out.
I wonder I wonder if my predictions will be right?
The jelly beens are looking like they are in a x-ray minion.

I see I see the vinger making the the materle stick to the jar.
I think I think that the vinger is helping it stick.
I wonder I wonder if it depends what sort of materle you use?
The materle is only just changeling  a little bit.

I think that the materle will turn white.
I see
I think
I wonder

Anna: I see that the mordant does not make much of a difference to the colour.
Grace r : I sore the fabric trying to ritziest the mordint.
Tawhara: I see the mordant sticking to the fabric
Ben I: I wonded if the mordant would make differents.

Color Changing Milk

EXPERIMENT

1. Pour enough milk in the dinner plate to completely cover the bottom to the depth of about 1/4 inch. Allow the milk to settle.
2. Add one drop of each of the colours of food colouring to the milk. Keep the drops close together in the center of the plate of milk.
3. Find a clean cotton swab for the next part of the experiment. Predict what will happen when you touch the tip of the cotton swab to the center of the milk. It's important not to stir the mix. Just touch it with the tip of the cotton swab. Go ahead and try it.

I see...

I think...because

1. I wonder what will happen when... I place a drop of liquid dish soap on the other end of the cotton bud. Place the soapy end of the cotton bud back in the middle of the milk and hold it there for 10 to 15 seconds. 

I see...

I think...because

1. I wonder what will happen when... I add another drop of soap to the tip of the cotton swab and try it again. 
2. Experiment with placing the cotton swab at different places in the milk. Notice that the colors in the milk continue to move even when the cotton swab is removed. What makes the food coloring in the milk move?

This is what I changed...

1. Repeat the experiment using water in place of milk. Will you get the same eruption of color? Why or why not?
2. What kind of milk produces the best swirling of color: trim, whole milk, cream? Does the fat content of the milk affect the reaction?

The dish soap must remain the same in the experiment. Use the same brand for each trial and the same amount of soap. Use the same colors and the same amount of food coloring in each trial. Pour the same amount of liquid into the bottom of the dish. All of these steps ensure that you have standardized the conditions as much as possible and have isolated a variable--the one thing that changes in the experiment. In this case, the variable is the type of milk you are using. Take photos of the reactions (maybe even videotape the reactions) to document your discoveries and share at the science fair.
