Why Science in English?
• Science in English gives children a chance
to learn English within a context of anothersubject.

• Through Science, we can reinforce
language and vocabulary, by applying a
cross-curricular approach to our teaching.

• Children do not only acquire vocabulary
and language structures but also gain
knowledge and understanding of scientific
concepts while cognitive skills are tapped
and developed.

It should be recognized that internalization
cannot simply involve direct transfer of
“ways of talking” from social to internal
planes: a step of personal interpretation orpersonal sense-making is also necessary
(Leontiev 1981).

Science in the SpanishCurriculum
• British and Spanish curricula share the same objectives.
They aim to provide children with knowledge and
understanding of physical and social phenomena that
influence their lives.

• In the Spanish Primary curriculum
Science, Geography and History are
grouped in one subject known asKnowledge and Understanding of the
World. It contains a broader content of
information. The Science contents focusmore on Biology rather than on Physics or
Chemistry. The Spanish system puts
emphasis on knowledge and study skills.

• In theBritish curriculum Science,
Geography and History are two different
subjects. More importance is given to
Physics and Chemistry and they are
taught mainly through investigation andexperimenting. Children are taught to carry
out experiments and draw conclusions
from them.

WHAT IS A F AIR T EST ?
A FAIR TEST is a type of scientificinvestigation where a condition (anindependent variable) affects anothervariable (dependent v ri ble), while all theother conditions of the experiment is
maintained constant or the same.

When scientific procedure is carried out by
way of an experiment, it is important to
teach students to record the experiment in
a systematic and scientific manner.

• An additional section for English language
learners may be essential vocabulary .
These are the words teachers consider
important for students to have as active
vocabulary. Active vocabulary is made upof words students know and use.

• There are six parts to recording
experiments:

HYPOTHESIS
PREDICTION
MATERIALS
PROCEDURE

HYPOTHESIS is a suggested explanation of
a phenomena; an assumption
8/12/2019 Fair Testing Science
http://slidepdf.com/reader/full/fair-testing-science 16/30
PREDICTION : a forecast of what will happen
based on the hypothesis
8/12/2019 Fair Testing Science
http://slidepdf.com/reader/full/fair-testing-science 17/30
MATERIALS: what is needed to carry out theexperiment

PROCEDURE: series of steps to be carried out.

RESULTS the outcome of the experiment. Thismust be recorded carefully.

CONCLUSIONS: trying to explain the results
in the light of their hypothesis and prediction

Essential vocabulary are the importantwords students have to know.
Key structures are the phrases orsentences helpful for students tolearn in order to understand andexplain the lesson.

• At the beginning, students can be presented
with a chart to familiarize and get used torecording scientific experiments.

Choosing Variables
I will change:
I will measure and observe:
I will keep
these the same:

ASKING A QUESTION
When I change (what I changed or independent variable)
What will happen to (what I measured or dependent
variable) ?
