For the first 2 weeks of term we have been doing an amazing project with the Wellcome trust: The Crunch! It is all about food: where it comes from, how it grows, the nutrients it contains and how if affects our bodies! So today is your lucky day: to learn all about the Crunch at Irchester with us!! Every class in the school is taking part with different activities, not just in Science but in Maths and English as well. Every single child has taken one of our “mystery seeds” home for one night, and showed the rest of the class what it might grow in to! We’ve seen a cookie tree, a flower that grows its own sun and rain cloud so it can grow anywhere, and a space plant that travels between Earth and Mars.
We had a very special visitor: Sefan Gates The Gastronaut! He did an amazing show all about food and science: it has given the committee and Miss Draper lots of ideas for new experiments to do!
Year 5 and 6 have tested how much vitamin C is in different orange drinks using Iodine and starch. We discovered that there is twice as much vitamin C in fresh juice as in a fruit shoot, and hardly any in orange squash. We have also looked at Halo Priming which is where you soak seeds in salty water and to see if it changes how well they germinate. The results of that experiment will take a few more weeks! In groups we also created and performed a play to show how farmers are cutting down the rainforest to grow soya beans. Many of the soya beans are turned into food for cows, which are kept by farmers to provide us all with beef and burgers.
Year 3 and 4 are looking at why we need to eat different foods, because they all contain different nutrients. They made their own Top Trumps games, and their own pizzas! Then they tasted them and compared them to bought pizzas, three quarters of the class preferred the “school made” ones. Year 4 measured how much food is thrown away in the school kitchens, and are going to write a letter to the council asking them to provide compost bins so the food waste can be used for compost and energy instead of just being thrown into a landfill site. All of year 3 and 4 also went to Tesco in Wellingborough. They collected 10 different types of food from the shop to check for palm oil in the ingredients, and discovered that about half of all foods have palm oil in them. This is a problem as it is not very healthy, and the rain forests are being cut down to make space for growing the palm oil plants. Then they went into the staff only areas to see how Tesco recycle almost all their rubbish.
Year 1 and 2 are looking at lots of different fruits! Discovering how they look, feel and taste; investigating what countries they come from all around the world and what plants they grow on. They are trying to grow lots of seeds they found in food: like tomato seeds, apple seeds and even an avocado seed! They have also looked at how different foods are packaged to keep them safe while they are transported to the shops. In the lab, we investigated how food can be preserved, and tried making our own apple jam and pickled apple!
