Talking About Energy Generator

“If only we could build a noise energy generator, it would be very wonderful,” I said to my 7 years old son.

“A what energy generator, Mom?” he asked me.

“A noise energy generator. You know, sound is a kind of energy.”

“Do you remember everytime we hear something loud we feel uncomfortable?” I continued.

It’s like I was talking to a college student or someone, but I did talk to my 2nd grader son. He, our little astrophysiscs professor, listened to my explanation very carefully.

Long before this conversation I have already taught my sons that energy can’t be demolished. It changes form only. From light to heat, from movement to sound, etc. In short, my sons have already learnt physics.

I understand my sons capability so I pursue them to study science and I provide discussions at any time about anything they’d like to know. I found myself had a really hard time in understanding physics and chemistry while I was in school. I felt that those subjects were far from being earthed. I mean, those subjects were taught as they were only for completing the paper based test. Not applicable.

For example, I have just understood the meaning of 'salt withdraws the water'. When you put some salt on the floor of your house, you will see water comes out after some time. That’s because water is drawn by salt. That's also what happens when you put some salt onto meat or chicken. Water is withdrawn and the meat or chicken becomes dry. Not good.

Now that I have sons and they often ask me things I never thought before, I realize that teaching science from early will be a good thing to do. Don’t get me wrong, I don’t give them numbered problems to solve, I just let them to understand how nature works.

People often asked me, “Did you really teach your kids about it?” I said, “Yes, I did. But I simplify the words.”

Back to that noise energy generator. My son was thinking and asked me how to make energy through noise.

“Electricity comes from spinning turbin. How can noise turn the turbin?”

“Well, I’m imagining a line of towers along a busy road. The towers catch the noise comes from cars, buses and other vehicles and turn it into energy.”

My son couldn’t agree more, but he added something to my idea, “What if the towers had microphones?”

“That’s a great idea!” I said. “Then connect them to the loud speaker, right?”

“Yes.”

“And then the noise can turn the turbin,” I said happily as if I had found a remarkable finding.

The conversation went on and on. We talked about many ideas in generating energy. What a conversation. I don’t know whether this idea will come true or not, but all I want to do was just to tease that little professor’s imagination. Who knows in the near future he will perfect the idea and make it into reality.

Well, parents, do you like to have conversations with your children? What topic do you both love the most?

Teaching Kids About Hajj, Not Only Fun But Also Surprising!

Early in this September, my sons, Mr. Inventor and The Professor went on a hajj teaching ritual class. It is an annual class conducted by the regional teaching department. There were more than one thousand students from15 different elementary schools. It took place at the local square.

This year is special for us because male students had to wear ihram, a clothing of male hajj pilgrims. I was imagining it would be great as kids would learn almost the real hajj would like. The last year class didn't obligate male students to wear ihram, just white clothing.

Surprisingly, Mr. Inventor refused to attend the class.

"I will not go," he said.

"Why not?" I asked.

"I just don't want to."

Okay...it became a problem for me. I needed to find out what caused him not to. Mr. Inventor is 9-year-old now, so I think it is common for such a boy to feel uncomfortable about something new. Perhaps he wanted to look good with the ihram.

I persuaded him to go. I told …

My Siblings And I

It's the three of us. Yes, we are siblings. I'm the middle child. I have an elder sister and a younger brother. Both of them live close to our mom in Jogja. My Sister
It's so funny to remember our childhood. We were, actually, not good siblings. I seemed to always had arguments and fights with my sister. I didn't like her and I think that she didn't like me either. It's understandable as she's only 2 years older than me. My sister and I shared the same room for years. We had a big table in our room for us to study. It was the only thing, I guess, that we agreed to share. The rest were things that we called 'mine' and 'yours'. The next funny thing is I missed my sister once after she left home for college. She had to stay in Solo for her bachelor degree. She returned home once a month or so and that made me felt lonely. Then I started to miss her. And the feeling got bigger when she got married. My sister is a tough person. She lives with…

Beautiful Hijabs From Hidden Pearls [A Review]

Last December I went home to Jogja for a holiday with my family. It was an end-of-semester holiday actually and I spent most of the days with my kids while my husband came later. We stayed at my mom's house which used to be the place I live through my younger years. Coming home and enjoy the atmosphere of romanticism of the past is always wonderful. I took my sons to places I'd like them to see so that they can learn something new. And they would be able to get to know their mom better. I showed them my high school, the local library I used to go, even my elementary school reports.
