experiment lab report
what will happen when we add water, vegetable oil, food coloring and Alka seltzer tablet.(i thought it was going to overflow)
materials
- Plastic cup
- Paper towel
- Vegetable oil
- water
- dye
- Alka-seltzer table
How it happen:
First: we watched a video of what happens when we mix water, vegetable oil, food coloring and alka seltzer tablet.
Second: then the teacher placed the paper towel on the ground in four places.
Third: the teachers placed the plastic cup on top of the paper towel.
Fourth: then the teachers poured water into the cup.
Fift: next was the oil, as it got poured into the water it started fizzing a lot and tiny air bubbles started to form.
Sixed: then the teachers added the food coloring and it started slowly sinking to the bottom.
Last: when they added the alka seltzer tablet everything started to change. It was like a colorful lava lamp.
the water and the oil were fizzing together. Then suddenly it stop. And all you could see was that the oil and the water was separated. Once they put the food coloring in the cup the drops started slowly sinking into the oil but didn't go any further then the bottom of the oil. Last but not least they put the alka seltzer tablet in once it touched the oil cup it started fizzing and fizzing and fizzing, i thought it was going to overflow the cup but luckily it didn't. Everything started to finally mix together like a lava lamp. It was so SPARKLY.
There were four groups and they each got one cup one of them got red food coloring and two of them got blue and the last one got green. I got one of the blue. Once they put the food coloring in my groups one it turns out that my groups one was the slowest to reach the bottom. And when the teacher put the alka seltzer tablet in everyone's acted the same. With an EXPLOSION!
It is probably the most confusing experiment we've done so far and the prettiest.
The thing that i learned was that what waters made up of are more attractive to each other then oil.
If i use a different type of oil will it still work?
What would happen if we used all the colors and put them all together?
(It would probably turn brown and turn out like sparkly co-cola)
PS: weave done more experiments before.
