Science Fair 2017

Monday, April 17th, 2017

Boys participated in Peak Science Fair and then they presented their projects at Region VII Lower Science Fair at Ole Miss.  For Peak, they needed to create a hands-on stem activity.  So, they studied and created geodesic domes.  We took gumdrops and toothpicks so that each kid can create their own geodesic dome.

For Regional Science Fair, boys chose following projects.  When Arjun read about how Thomas Alva Edison experimented with different filaments to create a light bulb, Arjun wanted to do the same.  So, that’s exactly what he did.  He tested different filaments such as hair, copper wire, iron wire, wood, pencil lead, and nichrome wire, to see if they will glow or not.  He won 2nd place in the category of Physics and Astronomy in class I (1st – 3rd grades).

 

My kids do a short meditation everyday so Kabir wanted to do an experiment to see that if the same guided mental silence technique will make a difference to the stress level of elementary and middle school aged kids.  He wanted to see if our method can be proven scientifically to be helpful in reducing the stress for his peers.  We encouraged him to experiment with an open mind.  He worked with 12 subjects (one of which was Arjun) for five consecutive days.  This was first experience of meditation for eleven of the twelve subjects.  He recorded the subject’s perceived stress score on the first day and then on the fifth day.  The result showed reduction of stress by 40% on average by fifth day.  Each day, he recorded their temperature, pulse and blood pressure.  After that he lead his subject through a guided relaxation technique that involved relaxing instrumental music, slow breathing and saying positive affirmations.  After the relaxation, he recorded the subject’s temperature, pulse and blood pressure again.  He requested a written comment from the subject about the experience on the first day and then on the fifth day.  Overall, it made a positive impact and showed that the relaxation technique did help in reduction of stress.

This experiment was so beneficial to him personally that hopefully, it will make an impact on him for life.  He won 1st place in the category of Behavioral and Social Science and also, won the best project award for 4th – 6th grade category.

They also participated in “All About Space” organized by Peak Homeschoolers.  Arjun did the research about space stations very enthusiastically.  He did most of the work on his own.  The topic was very dear to his heart.  He created the Lego model of ISS.  Kabir used the model of the solar system that he had made with clay couple of years ago and wrote a poem about the solar system.

Science Fair 2016

Tuesday, April 19th, 2016

Kabir was inspired by the book, “The Boy Who Harnessed The Wind” by William Kamkwamba.  So, he created a windmill for the reading fair.  For Science Fair, he took the same project a step further and did an experiment to figure out the effect of blade numbers, blade length and windspeed on the amount of electricity generated by a windmill.

Here’s the video of the his tests: Windmill Science Experiment Movie.

Here’s the paper (in MS Word) he wrote after conducting the experiment: The Effect of Blade Numbers, Blade Length and Windspeed on the Amount of Electricity Generated by a Windmill.  We practiced first with our Peak Homeschool Group and then we went to Ole Miss for MSEF Region VII Lower Fair.  Kabir won second place in the category of Earth, Space and Environmental Sciences and he won best of Class II (4th – 6th grade).

Arjun chose to make his own motor for science fair.  He took the initiative to find a YouTube video, make a list of materials needed and explained the process to Amit in detail.  We were so impressed that we had to let him do this project.  Arjun made the motor with Amit’s help.  He did almost 80% of the work on his own including trying to write the explanations that needed to be printed out and glued to his project board.  He got the idea of making the motor from the motor that we bought at Hobby Lobby for Kabir’s Windmill project.  He impressed us with his understanding.  He learnt about the motor from a YouTube video.

Here’s the photo of his motor.  Here’s the movie showing his working motor.

Science Experiments

Wednesday, April 22nd, 2015

The months of February and March have been spent on following the experiment schedule from the following two guides: Tops Learning Systems GREEN THUMBS: Radishes #38 and Tops Learning Systems GREEN THUMBS: Corn and Beans #39.  We have not only enjoyed it but we learnt a lot.  I definitely recommend it.  I wish I had been taught this way.  Sorry, I didn’t take any photos.  I wish I had!

Also, the kids worked with Amit to prepare for PEAK Science Fair organized by Paula Cox.  Mr. Bob Swanson, Physics Instructor at ICC, was the chief guest at the PEAK Science Fair.

Arjun’s experiment was to find out which part of the hand had most germs left after washing.  We ordered Glo Germ Mini Kit for him.  Arjun had a great time doing the experiment.  I made him write instead of printing.  So, he practiced writing.  He learnt how to make graphs and learnt about scientific method.

Arjun's Experiment on Germs

Arjun’s Experiment on Germs

Kabir created a telegraph circuit.  At first Amit showed him how to do it and then he did it all by himself except when the wires needed to be stripped.  He learnt basic Morse Code and then did an experiment to find out if Morse Code is still useful in the modern world.  To do so, he compared it to modern technology – texting.

He wrote a paper – Morse Code: Is It Still Useful in Modern World.  Megan Ratts gave the idea of writing a paper.  This was just perfect for him because when he wrote it, he fell in love with his experiment all over again.  Heather Tate did the editing part.  He participated in MSEF Region 7 Science Fair – Lower Fair at Ole Miss and won the first prize for Class I (grades 1-3) in the category of physics.  We are thrilled about it.

This week, we made a periscope.  We followed the directions from the Exploratorium website and kids are having fun with this new toy now.

Water – Science Experiment

Monday, December 15th, 2014

We have been studying about water.  We have been doing many experiments.  Some were success and some weren’t.  Here, are a few that were successful.

We used Legos to represent the molecules of three states of water.

We noted down the temperature at which water boils (212F )

We read about buoyancy and so, we tried to create a Lego ship that can carry as much weight as possible.

Related to buoyancy we did the following experiment where the egg sinks in plain water as the density of egg is more than that of water.  However, when we add salt to the warm water, the density of water increases.  This causes the egg to float a bit.

While I was away from the house, Amit did an experiment with the kids where they noted the pH of different liquids in comparison to water.  They noted the pH for all the liquids on an envelope!  Even though that envelope was incomprehensible to me they enjoyed and they did learn from this experiment.
