On April, 24, 2013 Wednesday, we had an egg competition. Mrs. Tyvand, our science teacher, made a challenge for us. The nine, ten, and the eleven year olds were in the challenge. Before we start the challenge they had rules to tell. The challenge rules were to make a tall tower, but it needs to hold the egg carefully. They give us a package, full of items. We could use all of the items in the bag of things. We had only 12 minutes to do the egg tower. When were finished we have to stand back for 5 seconds. If the egg falls down we lose but if the egg doesn’t fall down we win!
We asked our classmates about the egg challenge. The first question was “Did your egg fail or not?”Philipp said,” At first our leader of the group gave us the idea to put newspaper on the ground then to hold it put tape on it, but then Hamza came and kicked our egg, so we failed. Sophia said, “it failed”. The next question was, was it fun? Why or why not? Isaac said” I like it because I like creating stuff, but we maybe need more tape. Aziza said,” It was fun because, it was a competition and I like competing stuff. ” What kind of item did you need more for your egg tower? Tom said, “Some more tape, some more of newspaper, 2 pieces of string, and a rubber band.” Amina said” So we need more tape, some more of plastic bags, newspaper, actually we need everything.” And that’s the end of the Interviews.
When we asked the questions to our classmates, it seems like they enjoyed doing the egg tower competition. We hope someday we could do it again.

Last week the 10 Year old students did a project from a non-fiction book of their choice and then made it into a board game (well most did, some did posters or brochures) so let’s just say a project of their choice.
Amina B, a ten year old student said “I wanted to do a poster but I forgot it in Croatia so I did a board game” It was not very stressful for Amina but “I didn’t have enough time.” She was not very positive about what she said about her game she said “(I) kind of (did a good job)”
Thomas B, another student of Mr. Macmillan said “I did a (type of) in a pickle game with marine life. He did not find it stressful but “… It was boring going back and forth (with his notes and writing it down.) ...”he thought that it he did a good job but “… It could be neater…”
Anton B, another grade five student did a board game as well. He was not so fond of making a board game because “I don’t like doing things by hand”. He found it a non-stressful because “… drawing is easy”
The last person was Liam C. he was very positive about his work and how he did on his board game.
Over all it took around two hours to four days. To make the project took about two hours to a week to make the board games. Most of all everyone thought that people would play their game. Especially Anton with a positive “I don’t know.”
This was no science report or anything like that. It was unique! I mean how often do you make a board game for non-fiction reading text!?

On Tuesday, our class separated into three groups of three. Each of the groups built a different boat; the Secret Potion Boat, the Rubber Band Boat, and the Balloon Boat. We did this to experiment with energy transfers. When we went outside, Mr. Macmillan and Isaac filled a trough with water and began a boat race.
The first boat to be tested was the balloon boat. The members of the boat were Aziza, Isaac, and Thomas. It was operated by a balloon, straw and carbon dioxide. When asked how the boat worked, Aziza replied, “Well, the air in the balloon went out the straw and pushed the boat ahead.” Thomas explains how the boat moved, “I think it worked because the carbon dioxide that our group blew into the balloon and because of the carbon dioxide blowing out from the straw that helped us power the boat which makes us successful.” To fix some problems the members of the balloon boat decided to put washers in their boat. Thomas tells us about things his group wants to do to improve their boat, “Tape some washers on the corners of the insides of the insides, enlarge the circle where the straw goes through, and get a new straw.”
The second boat to be tested was the rubber band boat the members were: Tom, Lukas and Philipp. Now Lukas explained how the boat works, “Our rubber band boat was operated by a propeller at the back and the propeller was located on the two chopsticks that were holding on a band together and those chopsticks were stuck in the milk carton and then the propeller was made out of milk carton. Twisted the band until tight and let go.” Tom expresses his thoughts how to improve the boat,” I think to make the better by cello taping the rubber band the propeller together with better tape and to pull back the propeller.” This is what Lukas thought why the boat worked,” It worked because if you the mechanism in the and the milk carton go. The string will unloose and then the propeller will move. The rubber band works because the propeller at the end pushes the boat forward in the water, that is how the boat gets its energy.”This is elastic energy that pushes the boat.
The last boat to be tested was the Secret Potion Boat. The members of the boat were: Sophia, Amina and Dina. This boat was a failure. Amina tells us why it probably did not work,” I think it didn’t work because we didn’t get to put the washers on and the bottle was too big.” The boat was made of a sports bottle, vinegar and baking soda and two balloons. First you attach the balloons to the sports bottle. Then you mix the vinegar and the soda, then quickly put the top in the water. The chemicals should react and push the boat forward. Now Dina explains us how the groups will make the boat more successful: “Maybe we could put more washers on the top of the bottle.”
Everyone in our class enjoyed making the boats, Isaac explains us why he enjoyed making the boat,” I did enjoy making the boat because, I like making things and I thought the balloons project was really fun for me and my team.” The winner of the boat race was the Rubber Band Boat, second place was the Balloon Boat and last was the Secret Potion Boat.

On April 24th we are having a egg drop. A egg drop is when you make a contraption to make the egg white and yolk to be seen. So you have to build a tool to break an egg.
The guidelines are size, materials, and the egg. Size – the device can be any size, shape or weight. Materials – any materials can be used... but we would get bonus points if it is used “ environmentally friendly“ materials. The egg will be provided from the school.
There are four age groups, but two main groups. Pre – school – 6yoc, 7yoc - 10yoc, 11yoc – 13yoc, snd secondary. The two main ones are: pre – school – 10yoc at (12:35), and 11yoc – secondary at (1:30). There are three categories Single scientist: design and build your device by yourself. Co – scientist: design and build your device with one friend. And family lab: design and build your device with more than one friend and/ or any other family members.
There are four ways to score. Effectiveness, creativity, aesthetic appreciation, and e
nvironmental friendliness. Effectiveness is how good it works. You would get 10 points: if the egg white and yolk can be seen. 5 points: if there is some damage to the egg, but no egg yolk cant be seen. And 0 points: if the egg did not crack. Creativity is how your egg contraption performed. 10 points: if the device had more than 2 moving parts and / or more than 2 steps. It should be a large amount of creativity and planning. 5 points: if the device had 1-2 moving parts and / or 1-2 steps. It shows some creativity and effort. 0 points: if the device only used “human effort“ (for example, you simply hit the egg with a hammer or dropped it off the roof). It demonstrated minimal creativity. Aesthetic appreciation means when the device cracked the egg neatly. 10 points: the egg was cracked neatly into 2-3 large pieces and / or the white and egg yolk were removed from the shell. 5 points: the egg was cracked neatly into 4-6 pieces and / or the white and egg yolk were mostly removed from the shell. 0 points: the egg shell was smashed into a large number of pieces that were mixed with the egg white and yolk. Environmental friendliness is made of recyclable materials. 5 points: the device was made of recycled or recyclable materials. 0 points: the device was not made of recyclable or recycled materials.
The person who decided to do the egg drop is Mrs Tyvand, she says “it helps solving problems with a group“. Mrs. Macmillan a 3rd grade teacher says “it makes creative skills and logical thinking skills to help in the future“. Thomas B, a 5th grade student says “I'm not certain yet, if I am doing it or not, but I do want to do it“. Amina, another 5th grade student says “I would make a car with a giant mouth“.

Last week, Mrs. Tyvand and some of the high school students started to help plan to have a Science Week. The Science Week is at our school, QSIS, beginning on April 21st. Staff and Students to Science Week to let elementary student see and enjoy science in different ways. This year, Science Week is based off of a TV show called Mythbusters, where they crack myths open. Our class will either prove, or dispel the Soda and Mentos myth.
First, we started off with a mission statement. A mission statement is to tell a certain group of people what you’re planning to do. Our mission statement was, “Does the type of soda effect the explosion when Mentos are dropped into the soda?” That told us what we are going to be doing for the experiment.
Next, before we went straight to the experiment, we stopped at the hypothesis. According to the Thorndike Barnhart dictionary, the word hypothesis means, “Something assumed because it seems likely of a true explanation.” A hypothesis is like a prediction. Everybody in our class had different hypothesis, but a majority of people thought it was because of two bad chemicals mixing. Dina and I are part of that particular group. This let us to the next step.
The, the class got back on track to the Drawing Diagram. The Drawing Diagram is the drawing of your prediction, not when you write your prediction. What Dina drew was a man next to a bottle of soda, and some Mentos. Then he put Mentos inside the soda. The soda went up and up! And it finally exploded! The Drawing Diagram helps make a movie image in your mind.
That was the end of Week I. Week II is going to be the actual experiment. That would be the day we’re going to test the different sodas with Mentos. That’s the 10 YOC warm up for Science Week. We will blog about this after the experiment.

These couple weeks in science class we’re learning about energy. Today we learned about energy transfers (how energy can change or transfer) and we got to play with toys (yay), but we also had to record in ways how energy transfers (aww). The way we recorded is we got a booklet of pieces of paper with five empty circles that we explain what happens and we connect the circles by one of the eight different types of energy. We got two minutes to play and two minutes to record the information. We had five stations and we rotated from station to station in small groups so the process took roughly 25 minutes.
The domino station is where, well, we got dominos. I’m a big fan of dominos so this was one of my favorite stations. The first thing my partner, Dina, and I did was line up the dominos so that they could knock each other over when we push one domino. We recorded that as motion energy (when the dominos move), gravitational energy (when the dominos fall down), and sound energy (dominos make noise when they fall down).
Another great station was the toy car station. We got mini, multicolored cars (the type that if you pull the backward and let go they run by themselves). I was pretty fun making the cars run into each other and “accidently” making them fly of the table. Dina and I recorded pulling the cars back as elastic energy when we let go of the cars it was motion energy and when they bumped into or fell off of something it was sound energy.
The most annoying, noisy and round toy is the Magic Ball. You might think that is literally “magic” but it is just a ball. But there are a lot of things happening in this white object. You put your fingers on the metal strips and it will make the most annoying sound that you have ever heard and a red light will flicker on and off. This works because there are two batteries in the ball and the metal strips are electrons making a circuit with your body. The battery is connected to RASS (Really Annoying Sound System) and the red light bulb. This could not be possible without energy. When you put your fingers on the metal strips it will make a circuit which is electric energy, then the batteries starts that is chemical energy, RASS turns on, sound energy. And the light turns on, that is Light energy. That is who the “Magic Ball” works.
What is that in the air? Well those things are the frog jumpers. They jump up to 1 foot! Just push the frog and up, up and away! This works because there is a suction cup connected to the frog. On the suction cup you will find a spring, that is because then the frog will jump. But energy is always there. You push the frog down which is Elastic energy, then the frog jumps Motion energy, the frog falls that is gravitational energy!
When you think of a generator you think of a gigantic electric thing. But what we played with was not like that at all!!!! It was a tiny generator. When you turn the handle sound comes out of it but you are also making it move so that means it is Sound and Motion energy. The engine goes on producing heat and electric energy! Then the light bulb goes on, that is light energy.

Energy is everywhere. Energy makes things work, from reading a book to cooking dinner. Some energy is stored as potential energy that has potential to do something. There are eight types of energy. The first type of energy is motion energy. Motion energy, judging from its name, is energy in things that motion. Anything that is currently moving is a form of motion energy. The second type of energy is chemical energy. Chemical energy can be found in food (though it mostly doesn’t have chemicals in it), gasoline, and batteries. Gravitational energy, the third type, is in things and humans that are about to fall down due to the gravitational pull. Elastic energy is stored in things that get pulled down to launch objects and people. Trampolines and pogo-sticks are a form of elastic energy. The fourth type, heat energy results in temperature. We use heat energy for most household jobs like ironing. Light energy, my favorite type of energy, is energy that gets taken by rays of the light. Electrical energy, as you probably guessed, is energy that electricity provides. Finally! The last one, sound energy. Sound energy is energy that sound waves carry. Energy makes everything happen.
