Why Science?

The thought of teaching science to a class of eager students has always filled me with slight dread. This is partly due to having little experience of science throughout my own primary experience as well as lacking any confidence surrounding science knowledge and experiments.

I decided to engage with this module in the hope that through learning about the theories behind science pedagogy my confidence and subject knowledge would grow. Not only have I learned masses about certain scientific areas, I have also gained better confidence in planning and delivering lessons.

Going into our first group teaching lesson I was slightly apprehensive as this would be the first time I had taught science and the thought of teaching my first lesson to experienced primary 6 pupils was daunting. I believe that working as a group provided ‘strength by numbers’ but also gave us the opportunity to share knowledge and ideas. Having the support of other students was also a confidence boost as it allowed us to step in and support each other in any areas of weakness.

For our second group lesson again we were in a group. I felt much happier about the thought of teaching science to a group of primary 7’s. As a teacher it is my responsibility to make sure that I have a secure subject knowledge. when we were first shown the list of topics we could cover I knew that I would have to do a lot of research, however this was extremely beneficial as it meant I was engaged with the learning process and also helped me to judge how much of a topic we could cover in the given time and also how complex we could take the concept. After reflecting on my contributions to the first group lessons, I identified areas of personal weakness which I hoped to develop and improve on.

Firstly, I believed that it was important to have a set of questions prepared in order to assess learning throughout the lesson. Although we did have a set of pre-prepared questions it was also important for us to acknowledge and answer the questions presented by the children throughout the lesson.

Throughout my time at university I have repeatedly heard lecturers mention the “hook”. A way of sparking interests in a lesson and gaining instant engagement. This is something we struggled with in our first lesson as we had a more mundane experiment compared to some of the others surrounding us. However, by incorporating fly-sticks in this lesson we instantly had pupils hooked on our concept and managed to keep their attention throughout the lesson. As a teacher it is simply not enough to have a good opening, we must be able to explain the idea and the science behind it.

I believe our second group lesson flowed well as we each presented a different experiment based on the concept of static electricity. Again, the benefit of teaching with peers was that if any questions were presented that one person did not know the answer to we could rely on each other to fill in any gaps of knowledge.

By engaging in this module I have not only learned a huge amount about science, I have also gained a greater insight as to creating educational vlogs. I have never made a video before and was apprehensive of filming and producing videos which would form part of my assessment. However, as technology becomes an ever-expanding part of society it is important that as a teacher I engage with learning about how technology can be used in the classroom. Vlogging in this sense was a great way of exploring and sharing our own personal findings however this idea could be easily used in the primary classroom. It would also be reasonable to suggest that vlogs and voice notes could be featured as a form of teacher/peer feedback.

This module has improved my knowledge of both the science curriculum and methods of teaching which in turn has created a newfound sense of confidence in myself and my teaching abilities which I hope to put into practice on my next placement.

A Visit to The Famous Grouse Distillery

After visiting the Famous Grouse Distillery I created a video based on my findings. I thoroughly enjoyed the visit however had to cut back on the amount of information included in this video as I felt it was more important to focus on explaining the main process – fermentation.

I believe that using diagrams provides pupils with a clearer understanding as they can visualise the concept. Although the process of fermentation presents some complex concepts, it would be reasonable to suggest that some of these can be briefly mentioned. However, in order to explore fermentation pupils must have a profound understanding of solids, liquids and gases. They must be able to build upon this knowledge to then explore chemical changes.

 

Fermentation relates to multiple Experiences and Outcomes. It also provides a great context for cross-curricular learning. The Scottish drinks industry has a huge historical background which could be explored by children. Whisky in particular plays an important role in Scottish heritage which could provide multiple opportunities for research projects within the classroom.

Science

I have participated in practical activities to separate simple mixtures of substances and can relate my findings to my everyday experience. – SCN 2-16a

By investigating common conditions that increase the amount of substance that will dissolve or the speed of dissolving, I can relate my findings to the world around me. – SCN 2-16b

Social Studies:

Learning in the social studies will enable me to:

  • develop my understanding of the history, heritage and culture of Scotland, and an appreciation of my local and national heritage within the world
  • Having explored the variety of foods produced in Scotland, I can discuss the importance of different types of agriculture in the production of these foods. – SOC 1-09a

What is Germination ?

Nature is all around us and I personally feel that the prominence of nature provides a relevant context for learning as well as providing multiple opportunities for children to engage in outdoor learning.

Plants provide the early years with the opportunity to classify and sort plants into categories and justify their answers. This type of learning is mainly based on qualitative observation. However as pupils become more confident with the different parts of plants, they can begin exploring the different factors which affect plant growth. This is a topic I have briefly touched upon within my video. In hindsight, I feel that it would’ve been beneficial to suggest methods of measuring and recording results. However, research does state that children should be actively engaged with their learning and come up with solutions to problems (Cross and Bowden, 2014). It would therefore be reasonable to suggest that pupils should have some autonomy in choosing the best methods for recording their data.

Learners have been described as visual, kinaesthetic or auditory (Hastings, 2005). Visual learners will engage more when a teacher makes use of videos and diagrams (Hastings, 2005). I considered it important to include both a diagram in my video as well as a real butter bean as I believe that this worked as a way of breaking down learning as well as being appealing to visual learners. I personally find diagrams useful in building firmer understandings which is possible one reason why I have tried to include them throughout my science videos. However, it is important that although pupils may have one preferred learning style they are not categorised as one type of learner (Cremin and Arthur, 2014). Teaching should be creative and appeal to each learner within the class.

Viewing this as a learner myself, I believe that through making a video I myself was encouraged to research and build upon my own understanding. This module has encouraged me to develop sound pedagogical knowledge whilst providing me with more confidence. By becoming more confident in my own understanding of a concept, I believe that I am developing new ways to portray this information to children.

Reflecting on previous classroom experience I understand that it is important for ‘Learning Intentions’ and ‘Success Criteria’ to be made explicit to children at some point throughout the lesson. It would have perhaps been of benefit to include a learning intention relating to the science experiment so the viewer had a clearer understanding of what skills they would be developing.

The Curriculum for Excellence Sciences Experiences and Outcomes (2009a, p2) state that biodiversity and interdependence state:

“Learners explore the rich and changing diversity of living things and develop their understanding of how organisms are interrelated at local and global levels. By exploring interactions and energy flow between plants and animals (including humans) learners develop their understanding of how species depend on one another and on the environment for survival. Learners investigate the factors affecting plant growth and develop their understanding of the positive and negative impact of the human population on the environment.”

Exploring nature is clearly a huge topic that requires a large amount of time. However, through enquiry based learning pupils develop transferable skills such as problem-solving, measuring and recording data. Seeking patterns is also linked strongly to art and mathematics. Through engagement with this module and other education modules, I believe that as a teacher it is vital to make these connections explicit to children. By doing so, children can see the relevance of their learning as well as creating their own links as to how they can apply their skills in their everyday lives.

The benchmarks (Scottish Government, 2009b) also explore how pupil’s learning can progress through exploring nature:

  • Pupils can observe, collect and measure the outcomes from growing plants in different conditions, for example, by varying levels of light, water, air, soil/nutrients and heat.
  • Structure a presentation or report, with support, to present findings on how plants grow.

The benchmarks present yet another opportunity for cross-curricular learning, by suggesting that pupils create a presentation or report there are key links to language and literacy and also ICT. I have no reason to doubt that pupils would be capable of creating videos to show their findings given the right support and resources.

Reflecting on Our Group Science Lesson

Our lesson was based on the separation of water and oil. It was important for us to assess the class knowledge at the start of the lesson in order to structure the lesson to suit each group’s needs.

Each group brought new ideas, different levels of knowledge and importantly different questions. Children’s questions are central to science and enquiry. It is important to encourage children to ask questions which they can find solutions to. Providing a context which excites children and engages them is central to learning. One problem we faced was being surrounded by experiments which involved acid and alkali reactions. The excitement surrounding these experiments somewhat took away from the engagement with ours. In hindsight, as a group I believe it would’ve been beneficial to communicate with our peers and gain a better insight as to what other groups were doing. This perhaps would’ve helped us assess how to best put our ideas into practice.

Having prepared questions is also key to good assessment and learning. In hindsight this is something as a group we should have considered more closely. In our plenary we introduced the word emulsion which left children slightly confused. It would have been beneficial to introduce the word at the start of the lesson as a plenary should sum up learning. Assessing group work can be difficult, and what works for one group may necessarily not work for the next. In a situation where you are unfamiliar with the children and their preferred learning styles it may be of benefit to have more than one prepared method of assessment. Assessment should not only tell a teacher what a pupil has learned, partly learned, and not learned at all. It should also identify areas of teacher improvement. By assessing our own performance we have the ability to adapt and improve our lesson for the next group, meaning that by the time the last group arrive our lesson should be well polished and clear.

Central to the constructivist theory of teaching and learning is social interaction. Children should be encouraged to share their thinking and ideas with their peers through talk. It was hard to engage all children in talk as they were unfamiliar with us as a group of teachers. Finding other ways to engage pupils in talk, breaking the ice or perhaps asking them to share ideas with a partner instead of the whole group would have possibly worked better. However, without knowing the children it was hard to plan for these uncertainties.

Identifying areas of weakness, as well as  areas of strength, will help my future practice. The issues raised from today’s lesson should help inform my planning for the next group lesson. This lesson has also contributed to building my confidence as a science teacher as it was a good experience having other contributors to the lesson to learn from and create a wider knowledge base.

 

Putting theory into practice

The most recent science TDT asks us to explore and research one learning theory and consider and reflect upon how we might use this in practice. I decided to research the work of John Dewey.

 

I created a lesson plan based on butterflies as I felt this is something that would excited and interest an early years class. Dewey states that learning should be a balance between teaching knowledge and teaching what children want to learn and I feel like this can be reflected in picking a topic like butterflies.

 

Return To Science

I decided to select this module due to my lack of experience and confidence in the subject. As a teacher, I feel it is important to challenge yourself and gain subject knowledge in order to produce successful lessons. The thought of going into a primary classroom and conducting a large-scale science experiment is extremely daunting to me. I hope that through engagement with this module my subject knowledge will greatly increase alongside my confidence.

Today was our first lecture in the Science elective. This input consisted of a short introduction followed by our groups conducting a small science experiment. As part of this elective, it is a requirement to vlog our findings. I have decided to make a short video detailing today’s experiment and findings.

On reflection, as a group, there were a number of things which we could have done to improve the accuracy of this experiment.  Cross and Bowden (2014) state that the key to any investigation is fair testing. Our experiment therefore could be considered flawed as we did not accurately measure the water in each of the boiling tubes meaning that the solids had different volumes of water to react with. When experimenting, there are many variables which can be changed, in this instance the variable was the solid. Although it is unlikely to have affected the outcome of the experiment, it could be argued that by using the same spatula for each substance cross-contamination could have occurred therefore altering the reaction/outcome.

 

This experiment was based on observation. Observations are qualitative changes which are easy for people (pupils) to understand (Cross and Bowden, 2014), after grasping basic observation skills pupils can progress to measuring the qualitative changes.  Personally, I lacked any knowledge as to what the substances could be and was unable to explain why they reacted with water in the certain ways. As a teacher, it would be fundamental to have a solid knowledge of a topic before explaining it to the children.

 

However, it would have been of value to predict what each substance was and what reaction it might have when placed in the water and comparing this to the observed result. Cross and Bowden (2014) stress that predictions are important as they allow us to focus on the results.

 

This experiment was centred around soluble and insoluble substances. BBC Bitesize (2017) states that “soluble” describes a substance that will dissolve and “insoluble” describes a substance that will not dissolve. Although at the time this seemed to make sense. I decided it was important to research what makes substances soluble and insoluble.  Through research I have learned that it is the molecules of a substance which determine whether or not it is soluble or insoluble. Water is a polar molecule, one end is positively charged and the other end is negatively charged. Substances that do not dissolve in water are non-polar and do not interact well with water molecules.

 

To further progress pupils’ learning, this experiment could be extended to explore factors which affect solubility, these include: temperature, pressure, polarity and stirring speed.
