We think like scientists by carefully observing, predicting and explaining. We know we have to take our time and not rush the observations, otherwise we can miss things.
Being a scientist takes time and patience!
This week we are learning about fossil fuels, renewable and non renewable energy, and the impact these have on our environment.
First we matched up cards with the type of energy and where the energy comes from
We mixed oil and water together and learnt that they are 'immiscible', this means they cannot be mixed together.
We added detergent to the water and oil mixture and saw how this changes things. We observed that the detergent is attracted to both water and oil and helps join it all together.
We put water on a feather and observed how it stays sitting on top, but on a paper towel it soaks in.
This is how birds stay warm and dry, by having oily feathers.
Next we talked about how the fossil fuels 'Coal, Gas and Oil' are made and that they are nonrenewable, when they run out, they are gone forever!
We talked about renewable energy sources like 'solar, hydro, geothermal and wind power.
We made a model of how the fossil fuel oil is created. We used:
Playdough to represent the sea bed
Glitter to represent the dead sea life and sea plants that have sunk to the bottom.
Coffee mixed with water to represent dirt
Small stones to represent sediment.
We layered these, then squashed it all down really hard and observed how the liquid seeped out. This shows the process that creates oil, but over millions of years.
We are looking forward to the next learning learning we do with the science kit.
