Wednesday October 22nd - The Senses We've been learning about our senses this week. We carried out experiments to check them out.
Sight: Touching the ends of two pencils together using one eye or two eyes. We found that two eyes are better.
Hearing: We shut our eyes and Mr Musgrave made various noises and we had to guess what they were. We did really well and this shows that our sens of hearing is very acute.
Touch: We worked in pairs and one of us closed our eyes. The other partner placed something in our hands and we had to guess what it was.
October 2018 We have been studying The Weather in SESE this week. We made our own thermometer.
The first photo shows the thermometer when the room is cold and the second shows the thermometer when the room is warm.
Wednesday 19th of September - Dancing Raisins We have been investigating different forces in science this week.
We put raisins into a glass of 7-Up and into a glass of tap-water. The raisins in the 7-Up began to bob up and down from the bottom of the glass to the top and then down again. The raisins in the water just sank to the bottom and stayed there.
The 7-Up contains carbon dioxide which causes the fizziness. The raisin surface is rough and little bubbles of carbon dioxide cling to it. The force of all the little bubbles lift the raisin to the surface (like the balloons lift the house in the film Up). When the raisin reaches the surface the bubbles burst and the raisin sinks back down again.
After a while the dancing raisins became less active as the carbon dioxide leaves the 7-Up (this is what happens when soft drinks go flat).
