Research the solar system together, in a book or online. Talk about how you might decorate biscuits to look like the Sun and planets. To make simple biscuits, mix 200 g of butter and 100 g caster sugar together until pale and creamy, then mix in 300 g of plain flour. Ask your child to divide the dough into nine pieces – one for the Sun plus the eight planets of the solar system. They could try to represent their sizes, or even make them to scale! Roll out the balls into circles around 5 mm thick, and bake them on a lined baking tray at 160°C for 15-20 minutes.

When the biscuits have cooled, it’s time to decorate them. Set out any decorations you have to hand: icing sugar for dusting, melted chocolate for painting, coloured icing, or chopped up fruit. This is your child’s chance to be creative with the information they’ve learned. Will they add craters to Mercury, rings to Saturn or a great white sweetie spot to Jupiter? When the biscuits are ready, you could put them in order of distance from the Sun. This activity gives a hands-on focus to something that’s quite hard for a child to imagine, and it ends with an edible treat!

A scavenger hunt adds a fun science focus to a walk in the woods or a trip to the park. You can write your own list of things to find (look at books about seasonal change for inspiration) or download one from an organisation like the Woodland Trust. Take a bag along, or stick a few strips of double-sided tape to a piece of card, and peel them off when you get there. Then your child will be able to create their own natural art on the move.

Scavenger hunts encourage children to look closely at the world around them. Back at home, talk about the things they’ve collected. They could compare their collection with the results of a scavenger hunt from a different season, e.g. noticing that trees drop flowers in spring, and nuts in autumn. Children will be thinking like scientists as they make observations and notice patterns. Make sure they avoid picking wild flowers or berries.

Ask your child to create a mini sculpture using a pipe cleaner. They can dip it into cold water, then into a saucer of dry sugar until it’s completely coated. Leave it to dry.

Meanwhile, heat 250g of sugar in a small pan with 750 ml of water. When the sugar has dissolved and it starts to boil, take the pan off the heat. Be very careful when heating sugar, and don’t let your child near the mixture until it is completely cool. When the mixture is cool, pour it into a large jar or glass.

Bend both ends of second pipe cleaner to create a hook. Use this to dangle their sculpture into the jar of sugar syrup, hooking the other end over a pencil. Make sure the sculpture doesn’t touch the side of the jar. Leave their creation on a sunny windowsill.

Over the next few days, your child will be able to see crystals grow. When they are happy with the size and shape, remove sculpture and let it dry. This activity lets your child see that solids that dissolve in water have not vanished. They are still there, but broken up into pieces too small to see. As the sugar comes out of solution, it forms crystals. Talk about the shape of the crystals, or look at them through a magnifying glass. How do they compare to the original sugar?

This is a very popular activity, which gets even better if you scale it up! Tip a tub of cornflour into a tray. Half fill the empty tub with water and mix it in gradually. Talk about how the mixture changes. While it is still thick and gloopy, it’s time to play. Drop items in. Try pouring the mixture, banging the container, or scooping up a ball of goo and scrunching it tight. Relax your grip and watch what happens.

If you’re outside, get barefoot and try standing or jumping on the gloop. Mix science and storytelling by adding some toys – dinosaurs in a primordial swamp, or dolls in sinking sand? Cornflour washes off easily afterwards! The mixture doesn’t behave as we’d expect, which prompts lots of curious questions. It’s brilliant for experimentation and play, which are really the same thing!

Your lungs are like spongy balloons inside your chest that help you breathe. When you take a breath in, air fills your lungs, bringing in oxygen, which your body needs. When you breathe out, your lungs push out air with carbon dioxide, which is a waste your body doesn’t need. This breathing happens all the time, even when you sleep, to keep your body working and healthy.

When the card rises due to the weight of the coins,it drags a thin layer of water by cohesion.

You would think that if you placed a piece of paper on a glass and turn it upside-down, the paper would just fall to the ground, and it would, unless you change how you place the paper. In this experiment, I filled a glass to around just under a third of the way full with water and placed a square piece of paper on top. After doing that, I pressed down on the paper with force and kept my hand there, before turning it upside-down and gently removing my hand. As there were no gaps in between the paper and glass, the paper stuck to it. This is because when the water tries to escape, air must replace it, but the paper stops water flowing out and air coming in so the air trying to go inside the glass ends up making the paper stick.
