Science Reports from 2nd Class, Room 6
We experimented with magnets
We found out that
cloth and wood
are not attracted to magnets.
They are non-magnetic
We found metal was magnetic.
Things made out of metal like
and some coins
were attracted to magnets.
We found out how strong the different magnets were
by seeing how many paperclips they could lift.
We saw the designs a magnet made with iron filings
We found a magnet could work through a sheet of paper
We lifted a paperclip out of a glass of water without getting wet!
We learned about static electricity as a whole class
and it was very nearly the best fun we had.
Teacher had balloons, blown up all ready for us.

We rubbed the balloons on our jumpers and cardigans
to charge them.
When the balloons were charged they attracted
small pieces of paper
and the balloons stuck to the wall of the classroom.
The charged balloons were unfriendly to one another
and when one charged balloon
was placed beside another
they jumped apart.
The funniest thing was the way
a charged balloon made our hair
stand up on end.
We did this on a dry day
and it worked well.
On a damp day teacher had one balloon
and we were surprised when she showed us
that on a damp day static electricity
hardly worked at all.
Our favourite experiments that we did with light
was when we made rainbows.
We held the prism so that the light
from the overhead projector passes through it.
The rainbow danced high on the wall

When we experimented with water,
we guessed what would sink and what would float.
We made plasticine boats.
We saw how many dried peas they could hold before the boats sank.
Here is one of the experiments we did with sound
We got two tin cans and string
from the box of sound experiments.
There was a hole at the bottom of the can.
We threaded the string though each hole
and put a knot on the string to stop it pulling through.
We passed the can to a friend who moved
far enough away to make sure that
the string was tight.
We talked into the cup
and we could talk to our friend
We then let the string not to be so tight.
The sound wasn’t as good then.
