Did you know that Room 21 is full of young scientists? It’s
true! We have been learning how to think like a scientist and have started by
doing cool experiments.
We have begun by learning how to make observations like a
scientist would. We have used our five senses to help us with our observations.
The first experience we had was finding out which parts of
our tongues taste bitter, sour and sweet flavours. We worked with a partner to
drop a little bit of sugar, salt and lemon juice onto different parts of our
tongue to see if each part tasted the flavours stronger than others. We made
sure that we recorded our observations on a chart – just like a real scientist!
Some flavours definitely tasted stronger than others. The
tip of our tongue picks up sweet tastes, the sides pick up sour flavours and
the back picks up bitter flavours.
The next experiment we did was to see what would happen to
mnm’s when they were put into water. We made a prediction (a guess) before and
made sure we recorded it so we could refer back to it during the experiment.
I think the mnm’s will sink when they are put into the water
– Nivarah
I think the colour will come away from the mnm and it will
make the water dirty – Perez
During
our observation we made sure that we recorded any changes we saw. We also
checked what was happening against what we thought might happen (our
prediction). Look
at what happened!
At first the colours formed a wall. They didn’t blend at
all. We needed to keep watching. - Fesui
After seven minutes the colours started to blend together, a
white colour appeared. We think that might have come from the shell. We made
sure we kept recording what observations we were making.
We
love science in Room 21 and can’t wait to do more experiments next term!
