A study on Galileo related to science and Space and discoveries ideas etc - then once the children have seen and watched this they write this up as a study as a class - all were really engaged and would suit years 4 and 5 well - great for something a bit different to !
Air resistance Science lessons 1 and 2 - ideal stand alone lesson with included slides and activity sheets for the class !
Although this is aimed at Upper Key Stage 2, Year 4 and 3 could easily access the materials also and the activity sheets within this - There is 2 completed good to go stand alone separate lessons here but they could be edited to cover a short 4 or 5 week term as necessary
