Today we learned about how light was reflected off surfaces. This game can help you investigate this using torches and mirrors. I wonder if you can make the torch light all of the objects using the mirrors.
This week, in science, the children will be investigating the fact that light travels in straight lines. In order to do this, each class will need one shoe box between 4-5 children. We will need them by Wednesday please.
If any of you have empty shoe boxes – or boxes of a similar size and shape, we would be very grateful for them.
Thank you in advance
Today we had a wonderful time at the Think Tank these are some of the things that we saw. What was your favourite?
In science, this term, we have looked at rock and stones, and this week, we discovered how fossils are formed.
Something we did not really have time for, was to see how something, which looks like water, can actually contain minerals.
We discussed how water, rich in minerals, drips into the cavity left by bones, teeth and shells, and settles into the natural moulds before hardening in the shape of the animal or plant parts from many million years earlier, but have not actually seen how water can be rich in minerals – and yet the minerals are not visible!
An investigation you could try at home – with your adults permission of course – is to add a few tablespoons of salt into some warm water and stir until it is dissolved – and invisible! That water is now rich with minerals. Leave it for a few days/weeks until the water evaporates, and you will find those minerals (salt) still in the container! That is exactly how fossils are formed. (Although the minerals are a little harder!)
The children enjoyed finding out about Mary Anning, someone they had heard of in Year 2. More can be learned about her here. Watch the video of her life and try the game.
We made fossils, in the classroom – but did not really have a few million years to spend waiting – so cheated a little! Instead of waiting for the minerals to drip in and harden, we filled the moulds created by pressing a toy animal into plasticene with wall filler. We have still got to wait for it to dry out though before revealing our fossils!
In science, this term, we are looking at rocks. This week, we have tested rocks to find out if they are porous, how hard they are, whether they flat or sink and whether they are affected by vinegar.
We also used
to check our results and to find out about how rocks split as we were not able to try this for ourselves.
The children were very excited to find out that one type of rock does float! Another types of rock fizzes when vinegar is placed on it.
Over the next few weeks, we will be discovering how rocks were made, how fossils were made and how soil is made.
