experiment lab report(water cycle)

this week we made another lab report and this ones about the water cycle!
and here's my lab report.

Water cycle experiment

Materials:
  • plastic bag
  • marker
  • water
  • blue food coloring
  • Tape
  • a warm sunshiny area to put the plastic bag or tape it to a window that gets lots of sunshine


How we did it:
First: we got handed a plastic bag.
Second: we got a marker and drew on the bag the cycle of rain.
Third: then we went over to the teacher and she filled are plastic bags up(1 centimeter) with water.
Fourth: we went back over to the teacher and she did about two or three drops of blue food
coloring in the bag and the color magically transformed.
Fiffed:we sealed it up and made sure we left a tiny*tiny bit of air in it.
Sixed: then we got a bit of tape and stuck it on the window.

The change i saw was that it was becoming foggier and foggier each day some even foggier
then the others.

When you look really close you notice that it kind of starts to look like a geyser exploding out
of nowhere. But not everyone's turned out like a beautiful exploding geyser but it was still pretty.

  • Day one observations: it wasn't really forming at first but i could see it coming.
  • Day two observations: it was finally working and i really happy. Some of others was
  • working as well they all look super cool.
  • Day three observations:its become more steamier and blurry and same with everyone
  • else's.
  • Day four observations:I think it's reached the point where it looks like a bunch of clouds
  • shining down on the middle of nowhere

they all dont look that bad, they look kind of cool actually. But of course there's only one that
formed the most and one that formed the least. I don't think mine formed the least but it definitely
wasn't the most. I think mine actually formed second to least or third to least.

The word Evaporation means:the process of something abstract ceasing to exist.
The word Condensation means:the conversion of a vapor or gas to a liquid.
The word Precipitation means the: rain, snow, sleet, or hail that falls to or condenses on the ground.

experiment lab report

last week we were experimenting and here is my lab report.
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.
