As well as collating a collection of excellent websites, activities and resources for parents and teachers during the corona virus pandemic on the resources page of my website, I’m also posting a daily science or STEM activity on Twitter, Facebook and Instagram. I’m posting ideas seven days a week, through the easter holiday too, because science fun is for every day 😀.
Here are the posts from weeks five and six all in one place!
Have a go at this opening paper flowers activity 🌼🌸🌼🌸🌼🏵️
Use different size and different types of paper to see which one absorbs the water the quickest and opens up! Cut out flower shapes and then fold in the petals. Place in a bucket, bowl, sink or bath and watch them unfurl as the spaces between the paper fibres fill with water. Try tissue paper, printer paper and thin card. Which ones open up the quickest? Why do you think this is? What about if you try different sizes? Are small ones quicker than big ones? Why?
Can you see sound? Sound is caused by vibrations. Can you see the effects of a drum vibrating by putting some rice on a plastic film covered bowl? Find more sound activities in this sneak peek mini sample online science club at https://drjosciencesolutions.co.uk/online-science-club/
Today is #EarthDay
Find out about the water cycle with this simple activity exploring evaporation and condensation. Place a small amount of water into a resealable bag and tape it to the window. You could add some blue food colouring if you like to make it easier to see. Leave in a sunny spot and observe what happens over time as the water warms up and evaporates, then cools and condenses, falling back down just like rain in the water cycle.
Lots of new leaves are unfurling on trees. Can you identify what they are?
There are lots of dandelions about at the moment, but before you pull them up, they are a great source of food for bees!
Can you take a picture every day to see how the dandelions change over time?
You could even try to set up a time-lapse film to watch the dandelion flowers close up at night time and open up in the day!
Today I should have been at the Department of Zoology, Cambridge with my hero, David Attenborough, who once wrote to me! Do some secondary research and watch a natural history programme in his honour 🦧🦥
Today was also the second #GlobalScienceShow on twitter. Follow @GlobalSciShow to see a virtual science show from around the world. Here’s my small part all about woodlice: 📹 youtu.be/hA2rGJLeVmk
This weekend is the City Nature Challenge big weekend
📷 Take pictures of what you find this weekend
🔎 then identify them next week
Investigate the cohesive forces of surface tension by seeing how many drops of water you can fit on a penny – use a pipette, syringe or straw. Does it change with temperature? Why or Why not?
Natural pH indicators – you’re probably familiar with red cabbage as an indicator (which I LOVE!) but I’ve been inspired by @CrocodileChemi1 and @UncleBo80053383 to have a go with tulip and bluebell anthocyanins and try some microscale diffusion too – bubbles of CO2 form where the acid and base react. The colours in the indicators intensified overnight too! Why not have a go, or just make some ‘potions’ with flower petals?
Why not investigate the amount of sugar hidden in food! You might expect to find lots of sugar in sweets and cakes, but do you know how much is also hidden in things like tomato sauce and breakfast cereal? Use the information on the labels to do some secondary research and work it out!
Inspired by the popularity of my post about surface tension of water drops on a penny earlier in the week (and the currently weather!), I though we could try it on some rain drop shapes – maybe you’ll have more luck if your table isn’t on a slope!
Could you try it on different surfaces too?
Why not have a go at splitting the colour from felt tip pens using a technique called chromatography – you could use filter paper, blotting paper or kitchen roll. Just add a few dots of colour, dip the very end into water and watch it go!
Let’s explore floating and sinking today. Find some items from around the house; use a bowl, bucket, sink or bath of water – can you predict which float and which sink? Why?
Following on from yesterday’s floating and sinking investigation, could you find out if all fruit float? Why, or why not? Can you change it?
What’s happening in this picture? Do you know why?
