1. What was the mother upset about?

The mother was upset because a family of snakes
had made their home near the house.
2. Why was the writer happy to help her mother?
The writer was happy because it gave her an
opportunity to help her mother and invent
something to catch the snakes without hurting
them at the same time.
29
3.What are the three creative steps that the
writer takes to catch the snakes without hurting
them?
Step 1 She bought a stainless steel ice cream
maker and froze the bowl. She added ice cubes to
the top of the bowl to keep it cold. She placed
it over the snakes habitat during the day so
that the snakes would become sleepy and could be
easily caught.
Step 2 As above she did the same but placed the
bowls over the snakes habitat in the evening.
Step 3 As above but added a net to catch the
snakes.
30
4. Why did cooling make the snakes less active?
Snakes do not have a way of keeping warm in their
bodies. They get warmth from the sun and become
more active at this time. When the sun goes down
at night they cool down and become less active.
So extra cooling to the snake would make them
even less active and easier to catch.
