Nesma's Invention
921 Words
Nesma was reading the school newsletter when she saw an advertisement.
There was a competition for the best invention.
"look, laila," said Nesma. "This looks fun. I want to be an inventor!
"you should take part,"said Laila. "you'd be really good."
"look! If we win a medal, we'll get some science equipment for our school.
That's a brilliant prize! said Nesma.
Nesma loved inventing things. She thought about the competition as she walked home.
What could she make? She could invent a toy, a vehicle, or something to communicate with people.
She didn't know what to make, but she knew she wanted to take part.
At home, Nesma sat down. She looked at books and websites for ideas.
There were so many amazing inventions! How could she do something new?
She took out her pens and paper, and started to draw. It was difficult.
Nesma worked for a long time, but she couldn't get her ideas right. Her dad came home from work.
"That looks interesting, Nesma," he said. "What is it ?"
"Oh, it's a competition at school. I don't think i'll take part. I don't think i'll take part. i can't think of anything to make."
Dad sat down. "Show me your ideas,"he said.
Nesma showed him the papers and drawings, but she was sad . She didn't think her ideas were very good, For a long time. her dad didn't say anything. Then smild at her.
You know, Nesma, I know someone who used to make drawings and inventions like this."
He stood up and went out of the room.
When he came back, he was carrying an old box.
"This box has lots of things that used to belong to my mom,"he said.
"This was Grandma's? asked Nesma.
She looked at the box. There were letters and a diary, drawings and photos.
Grandma used to be an inventor, too!
There were plans for a vehicle that used a compass to navigate. There was a drawing of a wheel that turned in the wind and made electricity. Nesma found a drawing of a small toy car. It was on a track, but it was traveling upside down. Nesma was interested.
She read Grandma's note under the picture.
"I tried to make a car that could travel up walls and upside down. This would be amazing.If there was an earthquake, roads might be damaged. Buildings might fall down and make it hard to drive. We could use this car and make a track above the ground. Rescue workers could travel in dangerous places to help people But I couldn't find a way to make the car stay on the track."
As Nesma looked at the plan, she had an idea. she was learning about magnets in science lessons at school. Would that work?
The next day, Nesma told Laila her idea.
" That sounds great! Can i help?"said Laila.
" Yes please!"said Nesma.
Nesma showed Laila her plans. "We need some thin wood for a track, and a long , thin magnet to go under it. We need a small car to go on the track, with a magnet in it."
"I'll get the wood!" said Laila.
"Great!I'll get some magnets."
The two girls worked hard. They made a frame for the car to travel on.
They stuck the long magnet to the frame , and the small magnet to the car to keep it on the track.
The car had a little spring inside it . Nesma pulled the cat back, then took her hand off it. The energy from the spring turned the wheels. The car moved along the track, but it didn't travel very far.
"Why isn't it traveling?" asked Laila.
Nesma thought. She was worried. " It isn't fast enough," she said.
They looked at the model. What could they do? The sun was shining through the window, and lots of children were playing outside, Suddenly, Nesma had an idea.
"It needs more power!she said. "We can use solar energy!"
Nesma asked her mom to help her find the things they needed.
Her mom looked on the internet and found a small, cheap panel and a motor. They were perfect. Nesma put the motor on the car and attached it to the wheels. Then she put the panel on the car and used wires to connect it to the motor.
The friends tried again. They put the car in the sun, then started the motor. It worked! They watched happily. The car traveled along, up, and upside down!
"It's so clever! Well done, Nesma, " said Laila.
"Thank you for helping! It's fantastic'.
On Thursday, the girls were at the competition. There were lots of children from schools around the city.
" Are you excited? asked Laila".
"Yes, but I'm nervous, too, " said Nesma.
They looked at the other inventions. There were some amazing ideas and models.
"Look, there's a model of a house that uses wind to keep warm."
"And there's a machine that can help a farmer get water to lots of animals."
"There are some great inventions here. I'm happy we came," said Nesma.
"I'll write a diary about it when I get home, just like my grandma!"
The girls were busy talking about the inventions. They didn't see the judges standing next to them. They were looking at the model car and smiling.
" Well done!" said the judges, and the girls looked at them. There was a medal on their car!
"We've won a prize!" said Laila.
