Text

This weekend was just great. On
Saturday, I went on a field trip to
Stratford Butterfly Farm with my class.
Our Biology teacher Mrs Olivia planned
this trip for us a month ago, but she
had a bad headache on Saturday, so
she couldn’t go with us. Luckily, our
Geography teacher Mr Kevin was free
and he took us there.
The farm was very beautiful with a lot of
flowers, trees and plants. We saw a lot of
different butterflies there. Mr Kevin told
us about butterflies. We learned a lot
about them.
On the farm, there was a big pond. I was
very surprised to see colorful fish there.
We watched them with great interest.
There were nice gardens for picnics on
the farm. We had our lunch there. Then
we hired a boat and had a long boat trip
on the river Avon. Only 12 people could
sit in one boat. We were 22, so we hired
2 boats. It was interesting, because we
could see beautiful swans in the water. I
took their photos. They were very cute.
We got very tired at the end of the trip.
Some children slept on the bus. I took
their photos and showed them later. We
had a lot of fun.
