YEARS 7–12 IDEAS FOR THE CLASSROOM Year 7 Practical Skills for Inquiry Learning – Part 3 By Dr Jennifer Jones The activities described in Part 3 of the Year 7 Practical Skills follow from those described in the previous two editions of SEN 2019. The students have been undertaking activities which aim to build both their practical and thinking skills, in addition to increasing their overall confidence and competence at working in the laboratory. Again, we will be expecting their expertise to have increased, so we will not go back to square one with our instructions, but we will be on the lookout for instances where students may need a gentle reminder of what they have already learned! is important for deep understanding that students come to this realisation by themselves. While we have at the back of our minds that we want students to be able to decide whether a ‘fair test’ is necessary and, if so, how to make sure the test(s) are ‘fair’, as well as whether the tests and observations provide real evidence that allows them to draw valid conclusions, it is important that we give them no instructions other than a statement of the problem they are to solve. • Since the chemicals used are harmless and no heat is necessary, the safety precautions are minimal. You may choose to remind students about care when using glass apparatus. Since it is our aim to be able to use an inquiry-based (and therefore student-centred) approach with the students, it is important that we get them to articulate what they are doing/have done; why they have chosen to do this; what they have observed/ found out and what conclusions they have drawn – are they able to answer the question posed? The two experiments given below both begin with simple fun activities and then ask the students to experiment to find out what is causing the reactions which gives rise to the ‘fun’. In order to be able to come up with the answers the students will, in effect, have to use ‘scientific method’ approaches, although we will not formalise this in any way at this stage. They have also used this previously in the second part of the ‘Baggie Science’ experiment from Part 1. Patterns will emerge across the groups and these will be very important at a later stage when we do introduce this. • At this stage, early in Year 7, students will not want to sit down and plan how they will do the task and indeed may not yet be able to do so. They are more likely to want to dive straight into the practical, so let them! The teacher’s role is to circulate, offer support, keep things under control and ask questions which encourage the students to think about and explain what they are doing and why. It is important not to give them any direct instructions as to how to go about the task, except for the odd group which may have no clue how to start. Remember, we are trying to develop independent thinking skills, group work skills …. not “How to do what the teacher says” skills! Again the teaching/learning approach is student-centred so that the students are doing the ‘meaning making’ and are developing the practical and thinking skills needed for inquiry-based learning. Teaching strategies used in the previous activities will be useful here too. 5. Sherbet Fizz! • This is a fun activity which can be used early in Year 7 to help students build their understanding of how to investigate a problem scientifically. It can be used to further develop their thinking skills, practical/manipulative skills, co-operative group skills and to encourage their creativity as they work out ‘what gives sherbet the fizz’. • While the aim is to build towards using and appreciating the need for using, the ‘scientific method’ in some experiments, it 50 SCIENCE EDUCATIONAL NEWS VOL 68 NO 3
