Activity 7
• This activity is about making a
draft of the graphic and textual
components of the instructions.
It is common to define a graphic
format for a text and then adapt
the text even if the chosen
format was not appropriate. The
purpose of this activity is for
your students to recognize that
they should not be constrained
by a format and that they should
adapt the format as the text is
developed.

• In order to help in the decision-
making process, you might want
to check Activity 10 for ideas.
• Make sure your students
include and describe each
graphic and textual component
for all the sections they
defined for the experiment.
Activity 8
• Selection criteria are a way to
avoid being overrun by the
sheer quantity of texts available.
If you looked for the expression
‘scientific experiment’ using a
web search engine, you would
obtain more than 150 million
results. It is important,
therefore, to narrow your
search parameters.
• Web search engines have their own syntax, which may be helpful in understanding how to undertake
more precise searches. For example, there is the option ‘Advanced Search’, which allows you to narrow
your search by country, date, file format, and exact phrase. You may want to explore web search engines
for different results, if you have access to those tools.
Activity 9
• If you have difficulty finding experiments and texts, we suggest you use the ones you can find in the
Reader’s Book. In any case, this is a good opportunity to have a look at them and compare them with what
you and your students have found. Remember, the book is an aid for you and your students, but we do not
give you specific days on which to use it. Use it when it is the most convenient for you.

• The distinction between your students’ interests and reality may be quite shocking, but it is crucial for
developing this product. Even if your students find a really good experiment, if you deem it unsuitable for
material reasons, it would be better to have them choose another one than to engage in pointless work
towards an experiment that cannot be carried out.

• One didactic suggestion (in this book, dealt with in Activity 16) is to check how instructions are written
and if they are understood. So, it is very important to emphasize that the experiment should be able to be
performed by the addressee.
