What to do with this activity?
Chemical elements are the building blocks that make up our world. Everything we see, touch, eat, drink, breathe or smell is made up of a recipe of various chemical elements. A different recipe will make something else.
There are 118 chemical elements. 98 of those are found naturally on Earth, and 20 have been created in the laboratory. Chemical elements can't be broken down because they are made from just one type of atom.
Most things in our world are made up of a mixture of chemical elements. For instance, water is a mixture of 2 hydrogen atoms and one oxygen atom, so it's written as H2O.
Chemistry is all around us. Your child might like to watch the video above to find out more about chemicals. For more information see the "DK Find Out!" website and follow the links.
Maths makes sense to children when they use it in everyday life - like measuring things, working out distances, estimating food for dinner or money for groceries. The more opportunities you give your child to use the maths they learn at school through everyday activities the more they will understand and enjoy working with numbers.
Discuss maths that you see around you. For example, talk about sales in shops – half price, 25% off, what is good value? Or how much will the item cost after the discount?
