Week Beginning 1st February 2016 - Amelie and Elodie
In year four we have been doing 2 science investigations this half term. Our first test was to see which of the following solids melted first: chocolate, butter, wax , jelly or ice. The second test was to see which tin can (with water inside) would stay warmest for the longest. The can represented penguins because we wanted to find out where the best place is in a penguin huddle to keep warm! This is because in year four it’s our big freeze topic which is about Antarctica and penguins. The centre can stayed the warmest!
We also did some work on states of matter which are solids, liquids and gases. The bonds in solids are stronger than in a liquid where they’re more separated and in a gas they are much more spread out.
Year 4 Science Review of the Ice Investigations Day!
This week, Year 4 have been investigating various things to do with ice. This includes observing what happens to the temperature of ice when placed in different liquids or wrapped in different materials. Some people were timing how long the ice took to melt in different rooms, and a couple of people even tried to see how far they could push an ice cube on different surfaces! Investigating all of this was great fun, and we were all happy with our results.
It was great! ( -;) - ZH
Z’s Science Fair Blog
The Science Fair was on the 20th March. It started with experiencing the Solar Eclipse outside, using pinhole cameras and colanders to view it safely. Some people had special glasses to wear, so you could look directly at the eclipse without damaging your eyes.
Then we went back inside, and classes visited other classes and saw their experiments. We worked either in groups or alone to come up with our experiments, and had been working on them for a couple of weeks. There was everything, including chromatography, human reactions, chemical reactions, air pressure, and much more. Eventually, most classes got to see most other classes.
This was a fun and interesting way to end Science Week!
