Life Processes 4 Plants & Animals 4.6 Cells Sc 2: Life Processes 4 Plants 4.6 Cells P.O.S. Key Stage 1 Sc 1: 1,2f Key Stage 2 Sc 1: 1b,2e, 2f Key Stage 3 Sc 2: 1b,1e Life Processes 4 Plants & Animals 4.6 Cells LEARNING OBJECTIVES Is able to use a magnifier Knows that magnifiers can make objects larger and more detailed. Knows some everyday uses of magnifiers Can begin to explain why it is helpful to make things look bigger Know that animals and plants are made of cells. Can name some simple cell parts Know that plant and animal cells are similar in many respects Is able to use a microscope - possibly with help. ICT CD Roms Intel microscope ACTIVITIES Allow children to explore with magnifiers Discuss with children when they have previously used magnifiers Look at lots of objects using magnifiers and then the microscope on low power. Make finger prints and look at with a magnifier Look at pond water samples. Look at moss dry and then after water is added. Look at filter paper to see holes or fabric to see threads. Discuss and look for everyday uses for magnifiers e.g removing splinters, looking at small print, looking at finger prints, threading needles Make simple slides using sellotape and a piece of card. LINKS VOCABULARY Art Cell, microscope, magnification, magnifying glass/hand lens, magnifiers, plant, animal, nucleus, cell wall, cytoplasm, cell membrane RESOURCES POINTS TO NOTE Microscopes Prepared slides Boivewers Photographs Digital Microscope (computer) Iodine solution Slides/cover slips Home made playdough Saturated solutions e.g salt, sugar, alum Finger printing ink card Name of object here Fold sellotape over to seal in object Sellotape Microscopes can be difficult to focus and it might be better to use those recommended by Royal Microscopical Society for Primary Pupils. Digital (computer) microscope may be easier to use and ensure that all see the same. Use cellulose paste because wallpaper paste contains fungicide It is important that the magnification isn’t too large or pupils lose the sense of what they are seeing. When using a magnifying glass keep it close to your eye and move the specimen away until it is focussed. Life Processes 4 Plants & Animals 4.6 Cells Observe drops of saturated solutions as water evaporates. When and where do any crystals appear? Examine letters and newsprint – which way round are they? Use the INTEL microscope to take timelapse pictures of mould growing. Examine prepared slides of cells using bioviewers, hand lenses, digital microscope. Make slides of onion cells/animal cells. Draw what you see. Make a model onion/leaf cell/animal cell (2D). Make a 3D model of a cell (Small plastic bags filled with cellulose paste to represent cytoplasm, suitable objects to represent the nucleus – plant cells can also be made with the bags are squeezed into boxes). Ask pupils to identify how plant and animal cells are different. Label parts of cell: cytoplasm, nucleus, cell wall, cell membrane. Make model cells with coloured playdough and cut a cross section OWN ACTIVITIES POSSIBLE INVESTIGATIONS Compare finger- prints using different media? What makes the clearest prints? Life Processes 4 Plants & Animals 4.6 Cells Name: Date Record Began: Outcomes: NC Level 1 NC Level 4 1 Can use a hand lens or magnifying glass 1+ Can tell you that a hand lens makes things look bigger Can describe some things that they an see through the hand lens Can make a simple drawing of what they see with a hand lens Can label features seen with a magnifier that are also apparent to the naked eye Can describe simple differences between what they see with a hand lens and naked eye Can give an example of when it is useful to use a magnifier 2 2+ 3 3+ 4 Can make a more detailed drawing of what they see with a hand lens or microscope Knows that cells are too small to see with eyes alone Can use a light microscope that has been set up by an adult Knows that plants and animals are made of tiny building blocks called cells Can show you where to put the slide or object on a microscope and where the focusing knob is Can name some simple cell parts with prompting Can focus the microscope on low power Can label or annotate features of a drawing that are only apparent when magnified
