A Moldy Experience!

Posted on

Hi, this is Lilly and Claire!

Our class did a mold experiment to practice using the scientific method.  Our teacher said to pair up in groups of three for the project collaboration.  To go with the project, we made a science journal and we’re going to keep track of the results.

Here we are writing about our observations! We collaborated to get the best detail. We made our journals out of small gift bags.


First, we got a piece of bread.  We had to split the bread into three parts.  Then, we rubbed one of the pieces on a desk, one on a shoe, and the last on our tongue.  Each of us had to hypothesize which piece of bread we thought would have the most mold based off information we researched.

The petri dish with the three parts. Reminds me of a fraction!

 

After that, we put it in a petri dish.  The petri dish was split into three equal parts.  It was clear so we could see the mold as it grew.  We had to label it afterward so we knew which bread piece was which.   We put tape on the sides so it would be extra tight.  Once we had mold growing we didn’t want take the chance that it would open!  Yuck!


Look at what is happening to our bread!

Last we put it in a big black container under a desk.  We would check the mold twice a week.  It took a couple of weeks for the mold to become visible.   Once it did we were amazed at the different colors we saw!

Yummmm!

These are most of the colors we saw: yellow, black and blue-green.  We also saw white fluffy looking mold. Some people didn’t have any mold at all…my group!  Bummer!    We must be too clean.

There I am with my moldless bread! I am not looking too happy!

 

Here are some facts about mold…

There are five basic types of mold that grow on bread. The most common mold is penicillium.

Alexander Fleming discovered this mold.

He found that this mold kills germs. He used this to make a medicine called penicillin which saved millions of lives over the last 80 years.
Mold is…
not a plant.
like mushrooms and toadstools. 
one of natures cleaners.
used as flavoring for foods such as blue cheese and soy sauce. 

What do you think would happen to our world if we didn’t have mold?

 


Never Get an Addition or Subtraction Problem Wrong Again!

Posted on

Mrs. Fraher went to a math class by Kim Sutton and learned about the digital root of a number. When she taught us, she gave us a challenge to try to find out the theory of doing it with subtraction on our own.  Three kids found it out- Claire,Lilly, and me, Justin. We found this song on the Internet that was written by Kim Sutton and performed by Ron Brown… this is only part of the song.

performed by Ron Brown

Digital root, digital root, Can you find the digital root?
Digital root, digital root, Can you find the digital root?

The digital root of a number is the sum of all its digits.
Keep adding that sum, Until you’re done,
And a single digit is the final outcome.

That’s the digital root. Digital root, digital root,
Can you find the digital root?

Let’s take a number like 53.  Add the 5 to the 3
The sum is 8. You’re doing great.
The digital root is 8. The digital root is 8.

Our teacher challenged us to use Show Me on an iPad to teach others how to do digital roots for addition and subtraction.  Here are the problems we used digital roots for.   In order to do this, we had to create a problem, write a script so we wouldn’t forget what to do, and then we practiced until each of us knew how to do it without mistakes.  Each of us has a different kind of problem.

Here’s a couple questions by Claire:

Do you think digital roots will help you get better at math?  Will you get more problems correct on your test if you use digital roots?  Let us know!

 


Getting in the Team Spirit

Posted on

By Claire and Nathan

“Woooo Hooo!” “Yeah!” Whistle! Whistle! Applause! That’s what you hear when you go to sport games or events, because the people watch it and like to applaud to help the athletes. It is exciting for the audience.

Our class and the whole school wore our sport uniforms last Friday, because it was Sports Spirit Day at our school.

Since Nathan and I could write a quality blog comment, Mrs. Fraher let us write a quality post about Sports Day.

There are many great sports, but our favorites are soccer and gymnastics.

Soccer is a game (sport) played by two teams of eleven players. Other countries call it football. There are seventeen rules in the game. Like… no picking up the ball. No pushing other people, and score. Usually the players score by dribbling, passing, or shooting goals with their feet. Also referees can not kick the ball, because they are the ones who make sure people follow the rules.

The World Cup is the biggest tournament in the world. It is played every four years. Tons of people watch the games each year. Brazil won the 2002 World Cup and also won five since the tournament began. The World Cup is famous. It’s important because lots of people like to play in it. Crowds get together and cheer and go wild. They show their team spirit.

Claire’s favorite sport is gymnastics. Gymnastics is an active sport all around the world. Many girls and boys love to do gymnastics. People say that gymnastics is just an exercise for your body, but it’s actually just a fun activity that you can do. Gymnastics is a sport that provides many different skills such as balance, flexibility, concentration, and strength.

Gymnastics was used by ancient Greeks so that they could get on and off a horse. Circuses use a lot of gymnastics too. So, it has been around for a long time.

Gymnastic events have different performances that entertain people. People get to cheer their team on.

Cheering teams on creates an excitement and team spirit. There should be a day where every one should wear sport uniforms to represent their team spirit.

What are your favorite sports teams or events?

Why do you think it’s important to have team spirit?
