Magical Magnets 🧲

In our expedition lesson, we began to experiment with magnets, investigating how they work. We identified that opposites attract. This means that when you put a North Pole with a South Pole, they will pull together and ‘stick’! It was so fun to feel the force of the magnets pushing each other away when like poles were placed together – North and North, South and South repel!

Magnificent magnets 🧲

In our expedition lesson, we have been investigating how magnets work and what items around the classroom were magnetic. We found that when you put North Pole and North Pole together (the same) the repel but when you put North Pole and South Pole together (opposite) they attract. We found that items such as scissors, paper clips and coins are magnetic but things such as paper, cardboard and pencils are not. 🧲

Which materials are magnetic? 🧲

Yesterday afternoon, we explored a range of materials to investigate which were magnetic or non magnetic. We sorted our materials into 2 groups. We also discovered that that attraction was stronger with some items. To help us understand why some metal materials are magnetic we watched a video that explained for an item to be magnetic, it just contain cobalt, iron or nickel.

Magnets

In science we were looking at magnets and finding out which items were magnetic and which ones wont . We also looked at what happens when you put 2 magnets together. If you put N and N together they would repel , same for S and S but if you put S and N together they would attract. Here are our findings

How does temperature effect how ice melt?

We set up our science experiment by measuring 200ml of water to put in each of the jugs. We then placed these into the freezer for 24 hours. After they had frozen, we placed one in the freezer, one on the radiator and one on the table. We then measure the amount of water (ice melted) every half an hour and recorded the results. We then plotted a graph to show our results. We wrote all this up in a scientific report including: a title, prediction, equipment list, method, results and conclusion.

Science Experiment – Results! 🧊

Today, Crew Hamill completed their science experiment in which we investigated the impact of temperature on ice. We used the ice we had created in our last lesson and put them in three different places – on the radiator, on the table and in the freezer. We’d predicted that the ice that was left at a higher temperature would melt quicker and we were correct! We checked each block of ice at 30 minute intervals throughout this afternoon and measured how much of it had melted each time. There was almost double the amount of water in the cup that had been on the radiator as there was in the cup that was left at room temperature on the table. The cup in the freezer remained solid! This showed us that the temperature really does impact on the speed at which ice melts so the rising temperatures are a huge factor on climate change.
