Summer is coming!!!!!!!! School is almost over!!!!!!! But I bet all of you will miss......Blogging!!!
I really liked and enjoyed the blogging project. I liked the fact that we could post comments telling our opinions to my frieneds. I also really liked to post, since I could understand better what we did in class. At the start, I found it hard to write and explain perfectly what we did in class. When other people posted what we had to do for homework, it was really heplful, and I liked looking at the blogger instead of moodle. Overall, i really liked blogging.

Awesome Science Day
Today in class we had 5th graders joining middle school because it was shadow day. The 6th graders and 5th graders were in different groups together (made by teachers) in the scavenger hunt. In the scavenger hunt, for example, the 5th graders had to open our lockers, look on different assignments on moodle or make a comment to any scribe post written by a 6th grader. After the scavenger hunt, we got back to our normal class, science, and continued our lab, the paper airplane lab. In the airplane lab, we have to make any change to the paper airplane so that it can fly further. Our shadows (the 5th graders) got to make their own airplane too and got to test them. They also had to think of ways that the airplane would go further. For example the amounts of folds you make on your plane or adding the right amount of paperclips. The 6th graders didn’t really get to pay attension to our lab because we had to explain what we have done so far in science and we had to help them with the lab (some of them had no idea what to do). Today we had a fun day in science (like always), and all of our shdows enjoyed it too (I hope).
Get ready for tommorow 6th graders, another shadow day with the other half of the 5th grade class.
THE NEXT SCRIBE IS.................................TAMARA!!!!!!!!!!!!!!!!!!!!!!
Today our science class with Ms.D's words: "Hello everyone! You know what to do!". So everyone started working on our 'airplane lab'. We had to work on the following pages: 'number of wingtips', 'number of folds', and then we had to create our own purpose. So we had to test the airplanes (by throwing them), in the hallway.
The first thing we did was that we had to answer the IV (independent variables), and the DV (dependent variable). Then we had to write our hypothesis. After throwing the airplane from the 'start line', we had to take the meter sticks and measure the distance traveled. And after measuring, we had to record the distance traveled in our 'lab directions sheet' , that Ms. D gave us and you can find these sheets after going to our school website: www.aisz.hr.
THE NEXT SCRIBE POST IS.... NO ONE!

Hey readers!! Today in science class, we discussed VARIABLES and how to conduct aFAIR TEST!!! First of all, a fair test is a test that is re-tested three times to make sure that it is right, and in each of the times that you re-test it, you can only change one variable. Most of you readers, at this point, might be asking yourselves: "What the heck is a variable???" Well, a variable is anything that the scientist can change in order to conduct a fair test. There are many different types of variables:
Independent Variable (IV) which is anything the scientist testing the experiment can change,
Dependent Variable(DV) which is what the scientist measures and the actual result,
Controlled Variable (cv) which are all of the things a scientist needs to keep the same, and
Uncontrolled Variable (uv) which are all of the errors that the scientist can have made during the testing.
We watched again a Myth Busters episode were they made an experiment on trucks: do they go farther with the tailgate up or down? First, we needed to write a hypothesis on which truck we thought would go farther: the truck with the tailgate up or the truck with the tailgate down. We figured out that the truck with the tailgate up went farther, since the wind got blocked into the back of the truck, forming a "circle", so the wind coming from the top of the truck didn't fall on the truck, not provoking a drag. Instead, in the truck with the tailgate down, the was no "circle" in the back of the truck, which made the wind fall on the tailgate, provoking a big time drag. After the Myth Busters, we all answered some practice questions for a variables sheet.
Also, for the sixth grade readers, our only homework is (of course) the blog, and the lab!!!

P.S. I couldn't find the exact video we watched in class, but here is the Myth Buster's second try for the same experiment, since the fans complained about their science not being accurate......enjoy!!

Scientific Method
Hello everyone. I am sorry that I did not do my blogger on time.
For homework we had to : finish the shoe lab and not do the last quastion.
Variables
Doing a Fair Test: Variables for Beginners
It is important for an experiment to be a fair test. You conduct a fair test by making sure that you change one factor at a time while keeping all other conditions the same.
For example, let's imagine that we want to measure which is the fastest toy car to coast down a sloping ramp. If we gently release the first car, but give the second car a push start, did we do a fair test of which car was fastest? No! We gave the second car an unfair advantage by pushing it to start. That's not a fair test!
The only thing that should change between the two tests is the car; we should start them down the ramp in exactly the same way. Let's pretend we're doing an experiment to see if fertilizer makes a plant grow to be larger than a plant that doesn't receive fertilizer. We put seeds of the same kind in three pots with fertilizer and rich soil. But, we run out of soil so we put the seeds without fertilizer in three pots filled with sand. We put all six pots in the same location and water each one with the same amount of water every other day. The plants with soil and fertilizer grow to be much larger than the ones grown in sand without fertilizer. Is that a fair test of whether fertilizer makes a plant grow to be larger? No! We changed two things (type of soil and fertilizer) so we have no idea whether the plants with fertilizer grew to be larger because of the fertilizer or whether
the other plants were stunted by being grown in sand. It wasn't a fair test! All of the plants should have been in the same kind of soil,
Conducting a fair test is one of the most important ingredients of doing good, scientifically valuable experiments. To insure that your experiment is a fair test, you must change only one factor at a time while keeping all other conditions the same.
Scientists call the changing factors in an experiment variables.
Understanding variables
Malcolm used his grandmother's recipe to bake a loaf of bread.
Bread:
Grandma’s favorite bread
1 ½ Cups warm Water
1 package dry yeast
1 teaspoon salt
2 tablespoons sugar
2 tablespoon melted butter
3 I /2 cups flour
Mix all of the ingredients together., and knead :Cover
the dough, and let it rise for 2 hours. Put the dough in
a greased pan, and bake at 400" F for about 35 minutes.
Unfortunately, Malcolm's bread collapsed while it was cooking.
"Shucks!" he thought, "What could have gone wrong?" What
could Malcolm change the next time he makes the bread?
Two examples are given for you:
- He could add more salt,
- He could take the bread out of the oven sooner.

On Wednesday 6th grade got to watch ms.d dissect a sheeps eye. While we were watching our teacher dissect, we saw the different parts of the eye, for example, we saw the lens, the vitreous, the optic nerve, and so on. It was interesting watching the eye being disected, the part that I saw, and it was very educational. As you can see above this is a diagram of the eye.
Cornea - the clear, dome-shaped tissue covering the front of the eye.
Iris - the colored part of the eye - it controls the amount of light that enters the eye by changing the size of the pupil
Lens - a crystalline structure located just behind the iris - it focuses light onto the retina
Optic nerve - the nerve that transmits electrical impulses from the retina to the brain
Pupil - the opening in the center of the iris- it changes size as the amount of light changes (the more light, the smaller the hole)
Retina - sensory tissue that lines the back of the eye. It contains millions of photoreceptors (rods and cones) that convert light rays into electrical impulses that are relayed to the brain via the optic nerve
Vitreous - a thick, transparent liquid that fills the center of the eye - it is mostly water and gives the eye its form and shape (also called the vitreous humor)
The eye is a definitively amazing organ and without it we would not be able to see, or to have a visible sense of direction.
I hope you liked my scribe!
6th grade, for homework we need to finish our lab, due on friday! Remember that tomorrow, Thursday, we are welcome to come in during lunch for a study session about the EMS, the light vocabulary, the parts of the eye and the differences between mirrors, prisms and lenses! Be sure to come in!
Have a great day!

Monday, Wednesdy and Friday Lab!
This was the fun part. Now comes the horrible part! We have to do the 15 analyses and conclusions questions for next Friday.REMEMBER! You can always turn in a first draft before Wednesday.
Remember to study! We have a test on Friday! It is about the vocabulary, light behavior, EMS and the eye dissection. REMEMBER! There is a study section on Wednesday at lunch.
Hope you liked it! :) ! (:
The next scribe is.... Courtney!
