We LOVE encouraging learning and these questions are designed as a bit of fun for kids of primary school age. They offer a great way to learn about science and create all the the same time. And we all know that it can be incredibly helpful to have fun trivia questions as a slightly sneaky was of giving our kids a spot of learning in a fun way that’s engaging so they don’t even realise that they are doing it!

We have split our questions into specific age groups for you; and we do hope these work. If not, drop us a line and make suggestions. The trivia questions are designed for you to be able to chop and change things if you want to though as they don’t have age specific titles on any of the pages. This means that you can move sheets in and out and effectively use them how you see fit. We have provided explanations. Some include the odd fun fact in to help make the trivia games a little more interesting for you all. We have given a few samples of the printables below for you to see what they are going to look like.

All the Trivia questions are listed too, as well with interesting facts and explanations. We’ve got the answers for you in the final packs of course, but we couldn’t fit in the explanations on our printables. We have covered various topics and different subjects in science within the questions.

There are easy trivia questions, as well as some harder ones for the older children within your home, or school. You might even be able to do these questions on long car rides too – get them doing a little research on their phones while they are travelling perhaps?
