Text presentation
Hi Wang Mei,
How are you Everyone here is fine.
Do you want to surprise your friends Brian, Danny and I did an experiment in science class this week. I suggest you try it, too! First, get a jar full of water and a piece of cardboard. Cover the jar with the cardboard and turn the jar over. Next, take your hand off. Can you guess what happens The cardboard holds the water in the jar! The air pressure pushing up on the cardboard is higher than that of the water pushing down from inside the jar. The higher air pressure outside the jar holds the cardboard in place.
Science is interesting. Don’t you think so
Jenny
Dear Jenny,
I’m very well. Thanks! The experiment you did sounds interesting.
Yes, science is interesting, and it affects our everyday lives. Our lives would surely be very different without scientific developments. I always wonder what life would be like without computers or mobile phones. Scientific discoveries are making our lives better and better.
This week we had some science lessons, too. I enjoyed learning about DNA. It’s really one of the most amazing things on the earth! Scientists are doing so many new things with DNA. I think it will change the world. It will be interesting to see what happens.
