::: floating, sinking and predicting


We have been talking to teachers’ groups about everyday science and having discussions about simple experiments.

We all do floating and sinking-type experiments, but it is good to be able to think outside the square a little. Deborah at Teach Preschool showed us an experiement just using balloons and water.

 Have the children fill some balloons with air (differing amounts) …

 and some with water (again, differing amounts).

Let them hypothesise which will float and which will sink.

We tried this with our children and they were actually very on the ball with their predictions.

They knew that air was lighter than water!

This of course moved onto them hunting around for anything they thought could go in the water …

but we kept them on target by encouraging a prediction every time something was about to be tossed in.

Many teachers are afraid of science but …

science can be easy and spontaneous …

when you simply use whatever is at hand.

    Science really can be so simple! Sometimes, I think we as adults overthink it a bit!

    ::: Your right Debeorah and we are surprised by the number of adults who are afraid of science for that very reason. Science is simply ‘the discovery of new things’ something our children do every single day. Many teachers are surprised and excited when they realise that they are if fact opening their children up to science even though they didn’t realising it … And when that happenes for them it’s real WOW moment for me and Sherry too. :) :)

    I love doing floating & sinking in the water tray – it’s my favourite activity. We are actually going to be doing this next week too! Will make sure & take some pics.

    ::: We look forward to seeing what you and your children get up too Kierna! :) :)


  3. Love the balloon idea! Can’t wait to try this one.

    ::: Have fun Jill! :) :)

    The best advantages of science with young children for me is that it is hands on, perfect for the kinesthetic learners, as well as having literacy, numeracy & social skills like turn taking & negotiation embedded in most experiences.

    ::: Discovery is every where Greg … Isn’t it wonderful! :) :)

    My daughter (6) done this activity last week whilst in the bath lol, she was surrounded by all different items that she had me throwing in the tub while she guessed whether it would float or sink. A simple bath time turned into a science lesson :-)

    ::: Brilliant Aamilah … SEE Science really IS all around us! :) :)
