What a busy, exciting week Science Week has been! Take a look at these pictures to see what we have been up to.
First of all we carried out lots of different experiments based on the theme of sound.
Aisling watched sugar move because of sound vibrations.
“Me and my sister made a telephone out of paper cups and string to see how sound can travel. It really worked. We could really hear each other. It was fun.”
We made our own xylophones and composed our own songs!
Senan put different letters beside glasses of water. They contained different amounts of water. Then he spelled words by tapping the correct glasses.
Lots of us tried the Walking Water experiment. We learned that the coloured water moves up the paper towel by a process called capillary action. It was fun watching the colours mix too.
We discovered how flowers bloom in spring and made flowers that bloomed in water! We were amazed to watch them slowly open!
Katie and Robyn tried the Poke the bag experiment. Katie watered the herbs in her garden with the water when she was finished!
The Science Behind the Experiment– Plastic bags are made out of polymers, chains of molecules that are flexible and give the bag its stretchiness. When the sharp pencil pokes through the bag, the stretchy plastic hugs around the pencil, creating a watertight seal around the pencil…and the bag doesn’t leak.
These are some of our favourite experiments we discovered and tried ourselves.
As part of Science Week we carried out an Egg Drop Challenge!
We had to design and make a container or contraption to hold an egg and drop it from 1 metre. The aim was to keep the egg in one piece! Disclaimer…some eggs didn’t make it! If the egg cracked we tried to think how we could change our designs the next time to stop the egg from cracking. Judging from the faces on the videos that were submitted this challenge was enjoyed by all! Take a look at the video below to see for yourself!
We had such fun this week with this Egg Drop Challenge and carrying out all our experiments. Katie’s Mum sent us this picture which sums up our week perfectly!
