An aid for Year 5 children

1. ASTRONOMY & SCIENCE
QUESTIONS FROM YEAR 5 PUPILS
These are questions posed by Mrs
Genders class and answered by Tony
Jackson, a voluntary assistant at the
school.

2. INTRODUCTION
• SCIENTIFIC QUESTIONS ASKED BY THE PUPILS OF MRS GENDERS
YEAR 5 CLASS
• INTRODUCTION.
• I have produced this Information Folder for two reasons.
• I noticed in Mrs GENDERS Year 5 classroom that the children had
placed on a board on the classroom wall yellow sticky notes. These
notes contained Astronomy questions. As Astronomy has always
been an interesting subject for me I thought it may be helpful to
both the children and Mrs Genders if I provided and gave them my
own answers to the questions.
• In addition to providing my answers I could expand them so as to
include other information that may be in the children’s Science
curriculum.

7. SCIENCE QUESTIONS. ANSWER SHEET No. 3
QUESTION : HOW WILL THE WORLD END?
ANSWER.
There are several scenarios in which life on earth could come to an end:
 man is stupid enough to engage in nuclear warfare resulting in lethal radiation.
 Man continues to pollute the earth to an extent where the conditions become intolerable.
 An asteroid or similar space object collides with the Earth where the magnitude of the collision
throws up enough debris to block out the sun’s rays.
These first three scenarios are subjective and may never occur.
 The final scenario is an absolute certainty and nothing can be done to prevent it.
This is the natural way the world will end and it will occur in about another 5 thousand million
years.
As the Sun burns the chemical reaction converts its hydrogen into helium . When all the hydro gen has
been burnt several things will begin to happen. It will cool and swell up to such an extent that the inner
planets, Mercury, Venus and our earth will be engulfed bringing about the Earth’s death.
Our sun has existed for around four and a half billion years (4,500,000,000). During this time
the Sun has burnt up about half of its hydrogen content. Its remaining hydrogen will last a
similar amount of time so there is no cause for alarm yet. The Sun is expected to shine for at
least another four and a half billion years
