Experimenting in Science!


In JK we are kicking off Science in a fun way! Each week we have Science on Mondays and I will be involving the students in some kind of experiment or scientific adventure!!! This week we looked at density and experimented with water, oil and food colouring. Ask your kids how the experiment went! They loved coming up with ideas of what they thought would happen and they enjoyed seeing it occur.

I love to document and take notes of what the students say during our science experiments because they always amaze me with their hypotheses and I can really see their critical thinking skills in motion.


What do you think will happen when we add the oil to the water?

Students Responses: 

It will turn yellow.
It will make bubbles.
It will turn red.
It will go to the bottom.


What do you think will happen when we add red, yellow, green and blue food colouring to the water and oil?

Student Responses: 

It will add all sorts of colours to the water and oil.
It will turn blue.
It will turn into a rainbow.
It will change colour and make a rainbow.
It will turn pink.
The colour will go to the bottom and then pop back up to the top.
During the experiment the kids were amazed and really got involved in what was happening, lots of excitement!
Want to do the experiment at home? I know your kids would love to show you how.
Take a tall glass of water and put about 3/4 of a cup of vegetable oil on top. Once settled, add a few drops of food colouring and watch what happens. The kids thought it looked like FIREWORKS!!
The next day all the colours mixed into a brown/black colour and the kids guessed what would happen when we dropped a marble and a pom pom into the mix. Some students even said that the marble was heavier so it would sink and the pom pom would stay on top, which they did.
Science Rules!!!
