All over the Roman empire were mints where coins were made.
To make a coin, they put a disc of silver, gold, copper or bronze between two harder metal ‘dies;’ with back-to-front pictures and writing on them. Then they hit them with a big hammer, squashing them together and stamping the coin on both sides.
How do magnets, if rotated correctly, attract themselves?
Alexandre, aged 11
Y answered:
Hi Alexandre! Well, this is pretty complex, so let’s start with a simpler idea. When you stretch an elastic band, the work you do puts potential (stored) energy in the band. When you release the force, the elastic band snaps back, because things move in the direction which reduces the amount of potential energy. Pushing together like-poles (N-N or S-S) takes energy, so the magnets push each other apart (repel) to reduce the potential energy. When you put together two unlike poles (N-S), the potential energy in the magnetic field is reduced, pulling the magnets together (attraction).

British Science Week (5th-14th March 2021) was always first in my calendar as a Primary Science Co-ordinator and I usually started with very grand ideas! Whilst a whole week of science is brilliant, this year it might be more realistic to consider just planning one day – it will be just as exciting, but manageable both in school and for any pupils isolating at home. Here are some FREE ideas and resources for creating a super exciting Fly High Friday!
Did you know that Whizz Pop Bang magazine also creates curriculum-linked science resources for primary schools? Scroll to the bottom to find a brilliant offer that’s running throughout March 2021!
Here’s everything you need to make planning your science day as simple as possible:
A whole-school challenge with suggestions for each year group
Science lesson plan with curriculum links
Downloadable, printable resources
FREE PowerPoint presentations to help teachers run the day
Theme – Flight, linking with the curriculum topic of Forces with a comparative/fair testing enquiry and for EYFS the characteristics of learning.
Challengethe whole school to work together on a flight investigation! The mission: who can make paper fly the farthest? Keep reading to find activities and resources for each year group…
We all love to make a paper aeroplane but is that the only way to make paper fly? Here are some different ways:
For all these ideas you will only need paper, straws, sticky tape, glue and sticky tack – and some space, preferably outdoors! Each year group could have a go at making these different paper flying machines.
EYFS – Allow the children the time to explore how they can make paper fly. The teacher could demonstrate the air-powered rocket, then the children could make either the stunt planes or the straw planes. The children will choose the one they think will fly the farthest, try it and then the class teacher should record the result.
KS1 – Again allow the children the time to explore how they can make paper fly. Then the children should make each of the flying devices and choose the one they think flies the best, then test it. The teacher can collate all the results as a class.
Years 5 and 6 – children can test each design and then make their own flying machines. They should throw their final design five times and calculate the mean result. This will be their final result.
At the end of the day all classes should share their results. This might be by email or you could hold a virtual assembly! Don’t forget to ask for photographs so you can make a display or share them on your school’s social media platforms. We would love to see what you’ve been doing so please tag us @whizzpopbangmag

“Using Whizz Pop Bang school resources has enabled investigations to be an integral part of my science planning. I now have investigations and experiments throughout my planning rather than just at the end. The lessons are easy to resource and the pack has everything I need to teach the lesson so it saves me time as well!” Louise Hampson, Year 3 teacher

Make a volcano Print out a volcano template and create your very own miniature volcano using the harmless chemicals you find in your kitchen cupboards! You will need: the volcano printout below, a small container (e.g. a spice jar), bicarbonate of soda or baking powder, sticky tape, vinegar, red and yellow food colouring, uncoloured soap or washing up liquid, a tray.
Bubbling magma experiment Explore the difference between runny magma and viscous magma. You will need: two glasses, water, a viscous substance (like honey or golden syrup), two paper straws, safety goggles or sunglasses
We love this pancake recipe: BBC Good Food’s perfect pancakes but your science pancakes can be American style, vegan, savoury… whatever takes your fancy.
Next, decorate your pancakes with something inspired by space, nature, engineering or anything else linked to science! Here are a few ideas to get you started:
Today’s the day to get outside and do something to help nature! You could refill bird feeders and bird baths, plant some wildflower seeds or go on a litter pick. To make an upcycled bird feeder, you will need: An empty, clean and dry plastic bottle (e.g. milk bottle), a sharp knife, some sticks, strong glue or glue gun, 30 cm twine
If you want to do something inside instead, give these seed dispersal activities a go – it’s a great way to understand how plants and animals work together. To make a super-speed peashooter, you will need: Biro or gel pen, dried pea To make a model dandelion seed, you will need: A sheet of A4 paper, ruler, scissors, pencil, sticky tape

Pancake batter isn’t the easiest medium to work with, especially if you’re making thin pancakes that are often associated with Shrove Tuesday in the UK. We’re on the lookout for creative ideas and stacks of enthusiasm rather than anything that belongs in a gallery. After all, they’re not going to hang around for long, are they? Yum!
Living in a lockdown often means that we need to think creatively, so if you haven’t stocked up on pancake ingredients then there’s no need to go to the shops – decorate a biscuit, slice of toast or even a bowl of porridge instead!
