Explorify (https://explorify.wellcome.ac.uk/en/activities) is a fun science website we've only just started using. I'm suggesting this today because most of the activities just involve a tablet, phone or computer instead of lots of craft or ingredients being needed to entertain the children.
Sign up as a 'home educator' and you'll have access to their wealth of science games, videos, investigations and mind boggling puzzles.
Here's one for you...An object has been put under a microscope and zoomed up really close. Can you guess what the object in the title photograph is?
To find out the answer go to Explorify and type in 'Cosy Comfort.'
Have a fun day!
