Help your children learn tricky science words with these free primary science resources from our resource HUB. There’s no getting away from it – science words are big. Even some of the words that our children encounter from a really early age can be pretty daunting – think about herbivore, dehydration even microscope can be pretty challenging to remember when you are also learning tens of other new words a day. Luckily, although us scientists might be fans of overcomplicated words, we are (mainly) quite logical so by teaching children a few root words to recognise, we can give them a clue as to what the word is about and how to decode it which is a brilliant shortcut to teaching scientific vocabulary. The resource contains 2 printable pdf sheets with 18 root words and their meanings and a link to 2 online games: The root word matcher - using the same pictures as in the printables, children can match up the root word to it’s meaning. Decode the word - using the root words in the printable, the task is to match up the word to it’s description. The games are perfect to use on a whiteboard as a class or on individual devices.

A free printable worksheet for this really simple science experiment to show how surface area affects floating. Perfect for looking at materials, if you are doing stand alone working scientifically investigations or for something easy to keep up your sleeve when you need to kill 10 minutes! THE SCIENCE BEHIND THE EXPERIMENT The science behind the experiment is that as you give your animal bigger feet, you are increasing the surface area that the weight of the animal can be spread over and it can float upright. When it has tiny feet, all the weight is on that very small area so it is too unstable and falls over. TURN IT INTO AN INVESTIGATION There are lots of ways to turn this experiment into an investigation: Increase the size of the feet by a tiny amount each time, how big do they have to be for the dinosaur to start floating? Does the shape of the animal affect how big the feet have to be? This is also a great opportunity to think about fair testing. It’s important that the same amount of paper is used even if it’s in a different shape. Doing the experiment with different materials. How does the size of the animal affect the size of feet needed?
