Improvised Telephone

Steps to make the telephone:

1.Make a hole on the bottom of the cups.

2.Put a long string on the hole and tie the string  tightly so it might be connected to the second cup.

3.Do the same thing to the second cup so  it might be connected.

4.Go far to the second cup until the string is straight.
5.Try to talk into the cup and if it is working,congratulations!
conclusion
If we want to communicate with a cup, we have to tie the string strongly into the cup and it should be straight so we can hear each other.
Reflection
I like this activity because it is fun making the telephone and i can learn more about sound energy. Our group try very hard to make the the hole in the cups because we don't have any cutter. In making the telephone, we need to be concentrate in tying the strings. I love this project!

science activity that I like

I love science but I don't like to memorize it. I like the experiments in science because it is very fun!I also love to study about chemical changes because I want to know more about science.It is really fun having science but sometimes I'm lazy to study science because sometimes it is really boring.I like when I had the experiment of chemical change about 4 weeks ago, that is my favorite experiment of all times. For me, it is really hard to memorize the word in science book. I don't know some words in science book because some words are really hard.
