Welcome to Mrs Anderson’s Science Club! Every Friday at 3.30pm I will share with you some fun practical science activities which you can try out at home! Most of the activities will only need things that you probably already have lying around the house. If you do have a go, I’d love you to share what you’ve done by sending in pictures or a video, which I’ll add to the website if you have parental permission. Have fun!
Science Club – Summer activities
Hello all! As this is the last session, I have attached a document below which has a whole host of science activities for you to get stuck into over the Summer! Have a good Summer break!
Session 5 : 10th July 2020
Welcome to week 5 of science club! This week, why not have a go at making some Orange Fizz?! It’s really simple!
When acids and bases mix, you get some exciting chemistry! Oranges and other citrus fruits are filled with citric acid. It is a safe acid, and it’s what gives oranges, lemons, and limes their sourness. Baking soda is a base, the opposite of an acid. It’s also safe, but doesn’t taste very good on its own, and will give you a tummy ache if you eat a lot of it. As the citric acid and baking soda mix, it makes millions of carbon dioxide bubbles, the same gas you breathe out, and the same one that makes soda so fizzy.
Session 4 : 3rd July 2020
Welcome to week 4 of science club! This week, why not have a go at making your own lava lamp?
Lava lamps have been around for years and are mesmerising to watch. In this experiment, using no heat source we make a crazy lava lamp of our own.
You will need:
What to do
So what’s the science behind it?
At first the oil separates and sits above the water because it is less . When you add the vinegar or lemon juice, which is more dense than the oil, it sinks down through it and makes the coloured water at the bottom . Sometimes this doesn't happen right away and you will see little bubbles of the vinegar/lemon juice floating in the oil just above the coloured water! Don't worry, these bubbles will "pop" eventually and mix with the coloured water.
When the vinegar () and baking soda ( , a ) mix together a chemical reaction begins, and one of the products of that reaction is the same gas that we also breathe out, . This gas bubbles back out of the water and up through the oil, sometimes carrying globules of bubbly coloured water with it. When the bubbles pop at the surface, any water they carried with them will sink again while more bubbles continue coming up.
This carries on while the chemical reaction continues - you can keep adding more acid every now and then until it stops.
Session 3: 26th June 2020
Welcome to week 3 of science club! Thanks to Joel and Toby for sending in pictures of their investigation last week. This week we’re going to look at what happens when you add soap to milk which has food colouring in.
For this experiment you will need:
What to do:
What’s the science behind it? Milk has fat in it and the food colouring floats on top of the fat. The fat is all connected with bonds. Think of it like the little pieces of fat all holding hands with each other. Dish soaps are used on greasy or oily dishes because it breaks the bonds in fats allowing them to separate. When you add the soap to the milk, the fat separates and moves making your magical milk art!
Why not try more?
Does the temperature of the milk have any effect?
Try whole milk and skimmed milk.
Sprinkle pepper on the milk before you add the soap, what happens to the pepper?
Session 2 : 19th June 2020 M&M Experiments
Hello everyone! Welcome back to the second science club! This is a good excuse and reason to persuade your parents or carers to buy you some M&M sweets! Before you eat them all, have a go at the experiments below. You could try Skittles too – they would work too.
To begin this simple science experiment, slowly pour warm water in the middle of the plate. As the water moved from the middle of the plate to the rim, it touches the M&M's and begins to dissolve the sugar. Within seconds, you can watch as the colours begin to move toward the centre of the plate.
2. Floating M&Ms
Watch the clip (please note there are adverts): https://www.youtube.com/watch?v=1Odr5QFgcVw
Put 4 or 5 M&Ms in a bowl, with the M side up and cover with warm water. Watch what happens after the colour disappears?! Can anyone explain to me why this happens?
3. Make an M&M apple or heart
Make the outline of an apple (or a heart in red) with M&Ms. Cover with water, sit back and watch!
Session 1 12.6.20
Tornado in a bottle
Watch the link (this does have adverts at the beginning)
You can create your own tornado in a bottle. All you need is two bottles, a tube to connect the bottles, and some water.
When you whirl the liquid in the top bottle, it creates a vortex as it drains into the bottom bottle. That's because as the water flows down, air must flow up, creating a spiralling tornado.
You can even add glitter, food dye, or lamp oil to the bottle to make the tornado even cooler.
Please check with an adult before you do this experiment.
