BTEC first resources for biology

Discussion in 'Science' started by Afghan, Oct 20, 2008.

    I wondered if anyone had any suggestions about resources that could be used to enhance the biology bit. We have nothing for the classification and ecosystem bits.

  4. We used resources from KS3. The Exploring Science resources are pretty good, though I am sure most Schemes are similar.
    The criteria for a pass is very simple:
    P1 construct simple identification keys and describe the main characteristics within the major classification groups
    P2 describe an ecosystem investigated and indicate the types of interdependence of living things in it.
    For the ecosystem I downloaded a foodweb from Wikipedia pupils the used that as a basis to indicated the different levels (Producer, COnsumer etc.) and then discuss the interdependence on it.
    Unit 5 is quite unusual from these two incredible simple tasks to the more demanding section inherited diseases.
    Hope this help. Have fun

    Thank you for that it sounds like we are on the right lines but it is so difficult to tell. Can anyone give me an idea of what they expect for a distinction in the classification bit and what they have asked pupils to include in the ecosystem description for the next bit. This is giving me sleepless nights. I feel sure I am missing the target and will let my students down. Problem is by the time I have anyone say anything it may be too late!
     




  6. These are my 2 assignments. I go over the classification basics and keys

    We actually use this website for identifcation and to make the keys
    http://www.microscopy-uk.org.uk/index.html?http://www.microscopy-uk.org.uk/pond/
    and this website as research for the habitats
    http://www.blueplanetbiomes.org/world_biomes.htm

    Assignment
    1: Classifying Organisms
    </font>











    As
    a field scientist with the Environment Agency part of your work
    requires you to collect samples of organisms from an area to assess
    the environmental health of the area based on the number of types of
    species found. To do this, you need to be able to identify the
    organisms you find, using identification tables/keys. Simple
    Identification charts can be made to distinguish between similar
    organisms as a quick reference guide. Characteristics of organisms
    which indicate the possible evolution of the organism must be used to
    establish the correct identify of an organism. </font>






    This
    assignment gives you the opportunity to meet the following
    criteria:
    </font><font face="Comic Sans MS, cursive">

    P1:
    Construct simple identification keys and describe the main
    characteristics within the major classification groups

    M1:
    Explain the need to classify organisms

    D1: Discuss the
    characteristics which are used to distinguish the major groups</font>





    Task
    1: The training guide
    </font><font face="Comic Sans MS, cursive">

    a)
    Research information from text books, from websites or from other
    information sources to determine the fundamental differences between
    living things: Your task is to produce a simple leaflet guide to the
    5 kingdoms. You must explain how organisms are classified into each
    kingdom and give at least 3 examples of species that fit into each
    classification group. Your information must compile a training guide
    that is a maximum of 2 sides of A4 that could be used by your peers
    in the environment agency. </font>






    b)
    You shall be provided with a range of samples of different organisms
    from a variety of habitats. Select a group of similar organisms (eg
    snails, mosses, toadstools, or a part of an organism eg leaves,
    shells, twigs, berries). Collect 10 different examples of your chosen
    organism. Use these to identify characteristics and construct a
    simple identification key. Attach this to your training guide.


    </font><font face="Comic Sans MS, cursive">Successful
    completion of task 1 will allow to you gain P1
    </font><font face="Comic Sans MS, cursive">
    </font><font face="Comic Sans MS, cursive">Task
    2: The Presentation Talk
    </font><font face="Comic Sans MS, cursive">

    As
    a scientist you will often be asked to give a talk on the findings of
    your research as part of internal staff training.</font>





    Choose
    one organism from your chosen habitat and research its Linnaean
    Classification. Produce an A3 poster to summarize this information.
    Explain why scientists classify organisms. Why do they do this? What
    does this influence and how do they use this information? Relate this
    to your chosen organism.

    </font><font face="Comic Sans MS, cursive">Successful
    completion of task 2 will allow you to gain M1
    </font>



    Task
    3: Species discovery
    </font>




    <font face="Comic Sans MS, cursive">Biodiversity </font><font face="Comic Sans MS, cursive">is</font><font face="Comic Sans MS, cursive">
    very important. Living creatures are supported by the interactions
    among organisms and ecosystems. Loss of biodiversity makes ecosystems
    less stable, more vulnerable to extreme events, and weakens its
    natural cycles. A biologically diverse natural environment provides
    humans with the necessities of life and forms the basis for the
    economy. Everything we buy and sell originates from the natural
    world. New species are discovered by scientists, but unfortunately
    many species reach extinction every year. When a new species is
    discovered it must be classified. Watch the video clip ?new
    species?. Your task is to choose 3 species that have been recently
    discovered. Discuss why the scientists have classified each organism
    into its kingdom. How does each meet the criteria for classification?</font>




    Successful
    completion of task 3 will allow you to gain D1
    </font>




    Assignment
    4:
    </font><font face="Comic Sans MS, cursive">Organisms in
    their Habitats
    </font>




    </font>






    As
    an environmental science practioner you have been requested to carry
    out an investigation on the interdependence of living organisms
    within an ecosystem. </font>






    This
    assignment gives you the opportunity to meet the following criteria:
    </font><font face="Comic Sans MS, cursive">
    </font>



    P2:
    Describe an ecosystem investigated and indicate the types of
    interdependence of living things in it

    M2: Describe examples
    of adaptations to the environment shown by organisms within the
    ecosystem

    D2: Construct quantitative and qualitative diagrams
    to demonstrate the relationships between organisms living
    interdependently and within an ecosystem</font>


    </font><font face="Comic Sans MS, cursive">Task
    6a: Global Biomes
    </font>

    An
    ecosystem is a community of interdependent organisms along with the
    inorganic components of their environment, including water, soil, and
    air. Earth is the largest ecosystem, divided into biomes, large areas
    with similar climate and vegetation. A Biome is defined as ?a major
    regional or global biotic (living) community, such as a grassland or
    desert, characterized chiefly by the dominant forms of plant life and
    the prevailing climate?. </font>


    Your
    task is to choose a biomes and research this including the
    composition of the ecosystem, including it?s biological (biotic)
    and non-biological (abiotic) factors, the organisms that live in the
    ecosystem, how they interact and their adaptations to the
    environment. You must also discuss the impact of humans on this
    ecosystem.

    i) Describe the geographical location of your
    chosen biomes in the form of a world map. Discuss the climate of
    your chosen biomes.</font><font face="Comic Sans MS, cursive">
    </font><font face="Comic Sans MS, cursive">List 5 plants and 5
    animals that live in your chosen biomes. Choose 1 animal and describe
    in detail how it is dependent on other animals/plants for food,
    shelter and survival. Define, and give at least 1 example, of each of
    the following within your ecosystem: producer, primary consumer,
    secondary consumer and tertiary consumer. </font>






    Successful
    completion of task 6a (i) will allow you to gain P2
    </font>



    ii)
    Choose 3 organisms (either plants or animals) and describe in detail
    how they are adapted to live in their environment.</font>





    Successful
    completion of task 6a (ii) will allow you to gain M2

    Why
    is it better to use dry biomass as a measure, rather than fresh
    biomass?

    For this pond ecosystem draw accurate scaled diagrams
    on graph paper to show a pyramid of biomass and a pyramid of
    energy

    List 3 food chains that would be found in a British
    pond ecosystem

    Describe what happens to the level of energy
    within each trophic level as you pass up the food chain

    Describe
    the difference between pyramids of number, biomass & energy
    </font>



    Successful
    completion of task 6a (iii) will allow you to gain D2
    </font>
     
  7. Jot down your email and i'll send you all the biology scenerios we use at my school. Ps similar to the 2 already posted.



    ps if you've got access to the biology for you books/ scheme there are some good resources re classification keys etc.

    hope this helps

    Many thanks for the generous offer but I was actually after textbook and dvd suggestions as we already have our assignments sorted and are running the course. It has only been after we have done the first 2 assignments that we realised that specific resourses would waste a lot less time than pupils researching on the internet.
     
  9. Hi, i read your offer of help to the other messager, we are hoping to get the BTEC up and running for sept, the course supplied helpful phys and chem tips but no biol! any help gratefully recieved lynn.bedford@sky.com

    I've worked on some BTEC resources with another school (for some outreach work). Whilst they might not be what you want, feed free to check them out here.
     
  11. Just read through your email on the TES site and I would be very greatful if you would email the biology senarios that you use for BTEC level 2 applied science in your school..I have to teach this in Sept and really don't have much of a clue!
    In anticipation - many thanks
