    Hints on Completion of Homework

    Written Homework

    Homework is an important part of your learning. The exercises in this booklet are

    designed to help improve your understanding of experimental procedures,

    calculations, graphs, knowledge and understanding and gain experience in dealing with

    the types of questions you may encounter in an exam or test.

    You should make a fair attempt at all questions in the exercise. Homework exercises

    should be completed in your jotter. This booklet is not to be written on. Should you

    lose the booklet, it is your responsibility to replace it. A copy can be downloaded

    from the Hyndland Secondary School website.

    To ensure that sufficient graph paper is available in the jotter, any graphs should

    occupy half the graph paper page, so scales need to be designed to allow this (in

    exams you should use all the graph paper given). Each exercise should be started on

    a new page, with a date and title at the top of the page.

    These homework exercises provide an opportunity for you to practice the work you

    have covered in class. Under normal circumstances, you will have a week to complete

    each written exercise. If you are having difficulties, you should ask your teacher for

    help. You should expect around 1 written homework exercise per week. You can

    expect the exercises to be either self-marked, peer marked or marked by your

    teacher. A record of completion will be kept by your teacher.

    Online Homework

    Online homework is designed to help you test your knowledge and understanding of

    the work you are covering in class. It will help you develop a little and often study habit. You should use any resources available to help you get the correct answer including your class notes, printed notes, available textbooks and internet resources.

    Online homework is accessed from a link (quizstar.4teachers.org/indexs.jsp) on the

    schools website. You must record your scores in the table in your homework jotter.

    Only record your highest score.

    Under normal circumstances, it is expected that you should achieve more than 75%

    in your online homework. Your score is given to you at the top of the screen after

    completion. Clicking the review quiz button allows you to see which questions you

    went wrong in. If you have not achieved 75%, you can take the quiz again accessing it

    from the started quizzes option. After the second attempt, the correct answers

    for all questions are visible and you should use this to help you improve your

    knowledge. It should be noted that the questions are always presented in a random

    order, and therefore you need to know or understand how to get the correct answer

    the second time; its no good to simply remember Q6 is A because Q6 will be a

    different question, second time around.

    Homework forms an integral part of your National 5 Biology course. Fully

    engaging with homework will increase your success in National 5 Biology.

    QR codes

    At points throughout this booklet you will encounter funny looking

    squares (like the one opposite). These are called QR codes and

    are like the bar codes on tins of beans. A mobile phone with a

    camera can be used to scan them and they then take you to a web

    page, typically a Youtube video that might help you understand

    the part of science you are trying to learn about. They also

    appear throughout your summary notes and class booklet and refer to more videos or

    other features to help explain the Biological concepts or remind you of an experiment

    or practical technique you carried out in class.

    To make use of them you need a little app, a phone, tablet or the like with a camera

    and access to the internet. The system has been tested using an Android phone with

    the app Quick Barcode scanner which is free to download; Blackberry offers the

    free, QR Code Scanner Pro-Free, which hasnt been tested; the Appstore also offers

    free QR code scanners, QR reader or Bakodo again not tested.

    Please ask your parents permission to use this feature and as always ensure your

    security when downloading any app from the internet. In particular ensure you have

    disabled in app purchases before downloading any of the apps.

    The links have been carefully selected by your teachers, however if you find any link

    that you think explains it better, please let us know and we will add it in for next

    session. Enjoy your learning.

    1. The diagrams below show some human cheek cells as they appeared under the

    microscope, at two different magnifications.

    Describe the effect that increasing the magnification had on:

    a) the apparent size of the cells.

    b) the area of the slide seen.

    c) Why do we use stains when looking at cells under the microscope?

    2. The diagram opposite shows some human cheek cells as they appear

    when viewed through a microscope.

    The diameter of the field of view of the microscope is 120

    micrometres.

    Calculate the average width of a human cheek cell.

    3. Name the features found in both plant and animal cells.

    4. What additional features are found only in plant cells ?

    5. The diagrams below show sections of three different cell types. They are not drawn to the same

    scale.

    (a) In your jotter, draw a table to show the names and functions of structures labelled X, Y and Z.

    (b) Cells A and B are plant cells and cell C is an animal cell. Describe two features, shown in the diagrams, that support this statement.
