What it is
A friendly quiz show for curious minds. Every grade from Preschool to Grade 8 has twenty quizzes of eight questions: ten topics such as plants, animals, weather, matter, forces, Earth and space, then mix-up and challenge rounds. Questions use pictures, true or false, choose-all, numbers, short words, ordering, matching and tapping a part of a diagram. After each answer Olly explains the science in a sentence or two. Pre-readers get picture answers and every question can be read aloud.
What children learn
Age-appropriate science knowledge and vocabulary across life, physical and earth science, from the five senses and animal homes to cells, chemical reactions, Newton's laws and natural selection, with a short explanation after every answer.
