This session we went over the homework from last physics lesson. Harry is still struggling to identify the correct trigonometric identity (sine, cos, tan) for right angled triangles but did improve by the end. We then went over his case study on verifying if the claims made on certain brands of tape match the practical results, and next session we will review his log book and journal. We finished off the lesson by starting the topic of waves which we will contine next lesson.
