Rather than setting learning per day this week, we are going to go on a journey around Alchemy Island, learning all about the properties of materials!
Each of the challenges that you will face on your journey are below, along with some bonus Love to Investigate boards for you to try at home too - just remember to follow the steps on the boards carefully!
As we're being scientists all week, keep checking the enquiry cycle below to see which skills you are developing, as well as thinking about what new knowledge you are adding to your Science Capital bag!
Welcome to Alchemy Island!
The map above shows you some of the destinations we will be exploring on our travels this week!
The Island's Chief Alchemist has asked us to explore some materials from around Alchemy Island to help us get to know the area!
Now, unfortunately, the Chief of the island only sent the samples to school...but you can still explore some similar samples from your own home!
See if you can find as many of these materials, or something similar, around your home (the 'silver grit' would actually be spray painted lentils - shhh!) Don't worry about the 2 that are crossed out - ferrofluid is magical but expensive and you may not have jelly marbles around.
For each material, you need to test the following properties and record your results:
Record your findings in a table. Did anything surprise you?
There's a problem at the Bottomless Well near the Ancient Citadel! The water has been contaminated - there's soil, sand, pebbles, tea leaves and salt (or sugar - we can't tell as we are NOT tasting contaminated water to find out!) in it - eurgh!
You second challenge is to see how many of the contaminants you can remove from your own sample of water by using a mixture of separation techniques (sieving, filtering and evaporation). We did something similar earlier this year when we learnt about the River Nile - try and remember how we did each of them!
Watch the video below for a reminder if you need it!
Again - the Chief only sent the samples to school so you will need to create your own contaminated sample before starting the cleaning process! If you don't have the same contaminants, don't worry! You don't need to use all of them anyway.
Make your way through the long, dark halls of Dragon Vine Towers and find Alchemy Island’s Chief Alchemist, who lives there with his team. In his laboratory, there are benches are lined with reagents. Your task is to explore what’s on each bench and record your experiences, using scientific vocabulary to describe what happens.
Below is a document (you don't need to print it) with 3 ideas for investigations for this challenge! All 3 require things you might already have around your home and 2 of them are amazing! The 3rd (creating a plastic polymer with milk) will require more adult help but it's worth it!
Take photos of your investigations and email them to us at firstname.lastname@example.org - we really would love to see some Science in action!
Discover where to travel next by taking on a challenge set by the alchemists – hide the gold dust!
Add level spoons of ‘gold dust’ (caster sugar or salt) to one cup containing 50ml of cold water and one beaker containing 50ml of hand-hot water – stop when a saturated solution is created. Plan and carry out your test fairly, recording and your results. Look for any differences in the number of spoons of gold dust you added to the cold or hot water, then explain your results. Leave all or some of your saturated solutions in a sunny or warm place. Monitor changes that occur each day over a couple of weeks and note what happens when all the water has evaporated.
IMPORTANT KNOWLEDGE: A saturated solution is made by adding spoonful after spoonful of solute (making sure it all dissolves before another spoonful is added) until no more can dissolve. At this point, there is no more ‘room’ between the water molecules for the solute to occupy and sugar or salt granules will remain undissolved in the bottom of the beaker.
Continue the journey to Dragon Vine Towers and travel through Crystal Hedge Forest. A bag of mysterious gold crystals has been collected and placed in a cup of cold water to make the magic happen. What do you think will happen to them? Why might this happen? How much water would they need for them to change?
