Online Homework
Online homework is accessed from a link on the school’s website (staff
and subjects/ subject support/ S1_2 Science). You must record your
scores in the table below. Get a parent or guardian to sign after
completing every online homework please.
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. 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 questions are
always presented in a random order, and therefore you need to actually
understand how to get the correct answer the second time, it’s no good to
simply remember Q6 is A – because Q6 will be a different question
second time around.

Presentation Information
The presentation will be assessed in three parts:
 The powerpoint
 The sources used
 The act of presenting
The Powerpoint
Your powerpoint should contain:





A cover slide with a title
4 – 6 slides of data (one idea per slide)
Slides that follow the ‘6 of 6’ rule
References to where the data came from
Visuals to generate interest
The ‘6 of 6’ rule



Each slide has around 6 bullet points
Each bullet point is a key idea
Each bullet as around 6 words
This keeps the information short and snappy, keeps the words big enough to read
…….and stops the presenter just reading the slides
The Sources
You should clearly show that you have taken information from at least 3 reliable sources
and that you have used a variety of sources.
The Presentation
During the presentation you must:



Project your voice clearly
Make eye contact with the audience
Speak in sentences from the key points
