I would use the science kids website for some quizzes to complete after the lessons. There are also some amazing projects and experiment ideas on this website to give the teacher new ideas. The website includes super videos for the children to enjoy and resources are easy to find as they are grouped into topics.
Wow science has some interactive games and activities for the children to complete. There are some apps linked on the website, one which the children can monitor and investigate the sun and complete hands-on DIY activities to give a greater understanding of the sun. I would use this online resource to do a lesson on investigating the sun and moon – linking with maths night and day in the junior classroom.
I would use GetEpic! for storytime in the classroom. This website has a plethora of science themed books that are very engaging for children as it highlights the words as you read along with it.
