Isotopes are different forms of the same element. Isotopes of an element have the same number of protons and electrons but a different number of neutrons. This means they have the same atomic number ( number of protons ) but a different mass number ( number of protons and neutrons ). Paper Plate Isotope Models…
An element is a substance that cannot be broken down into another substance. Each element is made up of its own type of atom! The periodic table lists elements in order of atomic number and is laid out so elements with similar chemical properties form columns ( groups ). Atomic number is the number of…
Everything is made of atoms. Atoms are really, really small and are actually made up of even smaller particles called electrons, protons and neutrons. Atoms are not all the same. They have different numbers of electrons, protons and neutrons. Each different kind of atom makes up an element. An atom consists of a positively charged…
If you enjoy making things fizz, pop and bang you’ll love these classic chemistry experiments! Make a rocket, an exploding bag, write secret messages and lots more!Chemistry experiments are some of the easiest and most exciting science experiments to try at home or school and are often the ones that children want to try again…
Single use plastics are plastic items that are designed to be used just once. Things like food packaging, straws and water bottles are all single use items. Around half the plastic thrown away is single use, although hopefully, this percentage is dropping as the use of reusable drinking bottles and straws becomes more common Did…
The Avogadro Constant is used to find the number of particles in a substance. What is the Avogadro Constant? The Avogadro Constant is 6.02 x 1023 What is a mole? One mole of a substance is the amount of the substance that contains 6.02 x 1023 particles. The particles measured can be atoms, molecules, electrons…
Find out what pollution is, why it’s harmful, and how we can reduce it with these simple but effective science activities to teach kids about pollution. They are all great for teaching kids about pollution in a fun, hands-on way. Plastic pollution has become a vast global problem. Plastic rubbish ends up in the oceans,…
When I think back to my own childhood and school days, I don’t remember any chemistry experiments until secondary school, which is a shame because there are so many wonderfully visual easy chemistry experiments for kids that can be done at home or in school with young children. I’ve put together a collection of my…
What can you do with red cabbage? Firstly, you could eat it? Boil it, make coleslaw or stew it with apples, or how about some red cabbage science experiments? To make red cabbage indicator all you need to do is slice a small amount of red cabbage and boil it for about 5 minutes until…
Red cabbage indicator is a simple way to tell whether a substance is an acid or alkali. Acids can be found in the food we eat, in our bodies and around the home. Some acids, especially those found in cleaning products, can be very harmful, so take care when using them and always read their…
