Pressure in gases - complete lesson (KS3)

A full differentiated lesson based on the activate 2 (P3.3) SOW but can be used for others. The lesson covers pressure in gases and the effects of volume and temperature. Student understanding is checked with a differentiated question grid challenge. Atmospheric pressure is introduced ahead on the 'crushing can' demonstration - very easy; a can, water, tongues and bunsen burner is required (youtube for demo). Students then reorder statements to explain their observations. The effect of altitude on gas pressure is then discussed with use of examples. The plenary is an 'articulate' activity where students make logical and scientific speeches making use of key words from the lesson. Those with the most key words used can be given a reward. This lesson includes all answers for self/peer assessment and no additional worksheets are required. The use of animation and the choice of topics to explain each theory were chosen with an emphasis on promoting a love of learning. Timers are included to promote pace.
