Last Friday, the Science lesson in 3C was interrupted and we didn't get to complete our activities. We are going to start this week's lesson by finishing off that lesson. You will need to ask a grown up at home if they can help you get some of the resources you need.
Rocks for dinner
L.O. Can I collect and record data from observations and tests?
What kind of things are used to make a meal? For example, pots and pans. Make a list using the sheet attached.
Which of these items do you think come from rocks? Fill in the second part of your sheet. If you're not sure, simply put 'not sure' next to the item.
What about plastic?
Plastic comes from oil. Oil is formed between layers of rocks from dead plants and animals. So, what do you think?
We also eat rocks! Or rather, the minerals that rocks are made of.
Have a look at the food labels on some of the food you have at home (e.g. breakfast cereal, flour, bread, toothpaste, tinned and packet foods, bottled water and fizzy drinks). Your task is to decide which foods/ drinks contain minerals/ rocks. Use the internet to help you if you're not sure!
Task 3 - Consolidation
Lots of paper and cardboard is used in packaging. Most paper contains some clay - the glossier the paper, the more clay it contains! Cereal packets also contain clay to give them weight and make them easy to print on. If you can, weigh a magazine. Then, fold a newspaper so it is the same size and thickness and weigh it. Why do you think there might be a difference?
