Prior learning The learner is able to: • Link organs to different body systems • Identify ways to keep healthy • Name different types of microorganism, some of the conditions they need to grow and links them to common diseases Has this learner achieved this level? Inside the teacher’s head... Working through the second level outcomes and experiences, the learner has built on knowledge and understanding of the big scientific concepts relating to Biological systems. They are able to draw on this in different contexts and they respond consistently well to challenging learning experiences. They have further developed inquiry and investigative skills by becoming increasingly more independent and continues to develop scientific analytical thinking skills by applying their understanding to solve problems and provide solutions. Next steps Based on the evidence of learning, the learner’s next steps are identified as: • Investigate other sensory organs and their response to external stimuli and the role of technology in improving the quality of life when sensory organs are not working properly • Relate ways to maintain health and wellbeing to the biological processes required to sustain life • Investigate the role of vaccines play and how the body protects itself from disease • Contribute to the evaluation of news items in terms of the scientific content and ethical implications Body Systems and Cells - The function and potential problems of body systems and ways to maintain health and wellbeing In primary 5, as part of the class’s interdisciplinary work, the class looked at different body systems, including the cardiovascular system, the skeletal system, the muscular system and the digestive system. The learner then formulated their own question to answer; ‘How long does your food takes to travel around parts of your body?’ Working individually, they used a variety of sources and presented their findings visually on a poster. In primary 6, the pupils were working on a health and wellbeing project about keeping healthy. In order to challenge the learner’s thinking, they were shown a picture of their poster from the previous year and were asked to think about potential problems that may develop, possible solutions and ways to maintain health and wellbeing. Through their own natural curiosity, formulates a question to answer Develops an understanding of the digestive system Works individually to collate, organise and summarise findings. Learner comments “You might not chew your food well enough and it might get stuck. You would need to drink lots of water or juice. That would help. If you ate smaller amounts, it would stop it happening.” “Sometimes you get a bug or you might eat something that is bad so your body tries to get rid of it. You might spew or it might come out the other end. If you wash your hands it helps to stop you getting bugs and you need to check the ‘use by’ dates on food.” “You need to have a healthy diet, with lots of fruit and vegetables. Cereal is also really good for your digestive system. Mum likes Activia. She says the good bacteria in it helps to keep her body healthy.” Identifies problems related to the digestive system and applies an understanding of science concepts to provide potential solutions. Suggests ways to maintain health and wellbeing in relation to the digestive system Teacher comment The learner demonstrates a good understanding of problems associated with the digestive system. The learner has selected three different issues and been able to explain what can be done to maintain health and wellbeing in relation to these. Through discussion the learner showed that he understood that these are just a few reasons why it is so important to maintain a healthy lifestyle. The learner also showed an understanding of terminology related to this subject. Body Systems and Cells - The structure and function of sensory organs; response to external stimuli Following on from their first level learning in relation to the reliability and limitations of the senses, the learner undertook a project examining how two of the sensory organs, the eye and the ear, work and how this is related to their structure. They undertook a series of investigations to understand the function of each organ in relation to changing conditions and to investigate how this related to its structure. The learner was asked to produce a labelled diagram and write a report on her understanding of each. At a later date, the learner was asked about what they had learned and was then challenged to use her knowledge of the structure and function of the eye to give reasons as to why some animals have eyes close together whilst others have them further apart. Carries out a series of practical investigations to develop understanding of how each organ works. Recording Learner Conversation Animal Eyes Presents information using a diagram Recording Learner Conversation Structure and Function of Eye Uses knowledge to make reasoned suggestions and draw conclusions The learners debated around an article about new technology that could have an impact on their senses. Describes how the eye works Learner: The new glasses are really cool. I learned that wearing then is like having a computer attached to your face. Peer: The glasses are like a mobile phone and have a camera and 4G signal and work using your voice – voice command. You can talk to your computer or laptop and speak to friends on your mobile at any time and hear your music. Learner: But you can still see normally because the screen is on the edge of our field of vision. Ours is more straight ahead not like some animals so having the screen there means you can still see in front of you. Peer: They sound great – must be good to have music in your ears and see the computer whenever you want. Learner: Yeah but they look a bit odd - like a science fiction character Peer: And I wouldn’t want adverts in front of me all day. Learner: But you could see when your favourite programme was on at any time. Peer: Think I might get fed up after a while. And won’t they hurt your eyes eventually affect your sleep? Learner: You would take them off for bed Peer: But still – too much computer time before bed makes me awake and I get sore eyes- Mum says I forget to blink. Learner: Do they work in the dark? Peer: Yes just like seeing a computer in your house at night with the light off. Learner: Think they would make me fall over – you need your eyes for good balance and your ears – all that music and the screen at the side of my eyes would be really annoying. Microorganisms - Microorganisms in the production of and breaking down of materials As part of an interdisciplinary study into ‘Famous Scots’, the class studied the life of bacteriologist Sir Alexander Fleming, who discovered that mould produced the antibiotic substance penicillin. The class set up an experiment to try and grow mould using different food types. They recorded their observations on a daily basis. The learner was asked to summarise what they had observed and draw conclusions as to why the different changes had occurred. At a later date, the class investigated ‘Why Food Rots?’ In one experiment, they placed a range of different food substances in plastic bags and observed the changes. The learner used a variety of sources to help them draw conclusions. Later in the year, the learner was part of a cross school working group on ‘Green’ issues, part of which involved composting. The group was interested to find out about how composting works. The teacher used the opportunity to build on previous learning and challenged the learner to investigate ‘what happens in a compost bin?’ and provide an explanation to the others in the group. Learner comment “I know that mould is a living microorganism that needs water, warmth and nutrients to grow. The bread didn’t grow mould because it was in a container which did not let air and moisture in so the microorganisms couldn’t grow.” “There are times when mould is a good thing. It helps food to rot which can then be put back into soil which helps other things grow.” “Alexander Fleming discovered that a type of mound kills germs. Penicillin comes from mould and it helps to fight nasty bacteria that make you ill.” Takes part in collaborative investigations and draws conclusions Makes and records observations over time Recognizes the conditions that microorganisms need to grow Identifies the role of microorganisms in the production and breakdown of materials Acknowledges that microorganisms are useful to humans and plants Learner comments “The insects start breaking down the materials first. This helps the oxygen get to it so that the bacteria can work and it doesn’t turn sludgy and slimy. When the materials are smaller, the microorganisms produce enzymes to break it down so they can absorb the nutrients.” “You put the compost on the new plants to help them grow, so the dead plants are helping to grow new plants.”
