I’ve put together a comprehensive set of useful websites and resources for primary science activities, primarily for parents to use with children whilst self isolating/social distancing/supporting schooling at home during the coronavirus situation, but they may also be of use to teachers providing content in schools and online.
You can find them on my website at https://drjosciencesolutions.co.uk/workshops-2/resources/
Have lots of fun – make it memorable, experience-led and not worksheet heavy! I can’t take responsibility for content of external sites. Stay safe – and wash your hands!
