Our trip to the Mining Museum

On Tuesday 4th April, we took a bus to travel to the Mining (矿业) Museum because we had learning about the Gold Rushes.

__1.___. We went past some famous places such as Sydney Harbor and the Open House along the way. We also chatted to our friends about what we had seen on TV last night.

When we arrived at the Mining Museum, we were taken to a room where we stored our bags. Our guide, Alison, then introduced us to a man named Bruce Binkley who is a miner.

Mr. Binkley talked to us about how people used to look for gold. __2.__ . It seemed simple. You get a pan, fill it with dirt and water and then swirl (旋动) it around until the big stones are washed out along with other things. Gold, being heavier, is left at the bottom.

Next, we walked upstairs to look at pictures, information and samples (样品) of gold. We filled in a worksheet about the early discoveries of gold in Australia. ___3._. That part was really exciting because you had to imagine that you were a miner digging for gold.

Lunch was spent in a nearby park. ___4.__. They were yummy! We also played hide-and-seek while we were there.

__5.___. We boarded the bus and felt very tired. Some children even slept on the bus!

It was an enjoyable trip to the Mining Museum.
