Collision theory / kinetic theory crossword Do Now Students are required to 'fill in the gaps' to complete the crossword. The purpose is to check their understanding about the collision theory and how scientists can increase rates of reaction. This resource tests students on 7 words which are present at the bottom of the worksheet in a 'word bank'. To differentiate this resource for more able students, you could remove the word bank. The 7 solutions are: activation, collide, energy, kinetic, orientation, speed, temperature
