Magical Maths Week

 Hey Guys! Welcome Back!

Today (friday 28th of august) we had "maths week" (more like maths day). It was really fun even though it kinda hurt my brain the last activity. Sorry I don't have any photos or videos at all -_- 

Can you figure them out? It took me while on the first one but the second was easy and then the third was in between. Most people in my class thought that it said 7-4 but it actually says 7 and take 4 then add them both up. (just if you were also confused by that), in the third they do go really fast though. I'll tell you the answers in the next post (DON'T wait until then and then comment you answers and DON'T copy others if anyone else has commented)

I hope you have a fun time at home playing the games if you do ;)

So that's it folks, see you next time! :3

Really Rad Rocket

Hey Guys! Welcome Back!

So today we had to write about how our rocket test flights went. We only did one test flight but we got some good results. Also we had to read the first slide about the launching in front on the whole class my group was panicking because we aren't that good and get really nervous when it comes to public speaking. But luckily I just held the rocket and my friend did the speaking and my other friend stood next to us. Although my friend who read it aloud got really sick afterwards and felt like throwing up, I think it was probably nerves and I felt really sorry for her.

Anyways here is the slide for our test (oh and only go to slide four (center of mass) because we haven't done the rest because we don't need to yet until our next flight)

Have you made a rocket before? Are you any good at public speaking? I'm not.

Hope you enjoyed it and learnt something new!

That's it folks, see you next time! :3

*~* Super Samoan Digital Classroom *~*

 Hey Guys! Welcome Back!

For Wednesday before we go to tech we had to make a Digital Classroom. The Digital Classroom had to have all our work (slides) that we have done on Samoa. I hope you like it! :)

Oh and if you click on the bookshelf (the little black book actually says Samoan Alphabet but you'd have to zoom in to see) it will take you to one of my slides. Then if you click on the whiteboard (it says Samoan Greetings because that's what it will take you) it will take you to one of my slides. Finally if you click on the paper (it says Samoan Language Studies) it will take you to one of my slides.

P.S. The bitmoji character had to be coming out from the side because I couldn't find a descent one that was sitting.

Here it is! :>

Oh and I'll be making a video of it as well so if you can't get to the slides or you want me to read it and because our teachers say we have to.

Did you like it? Is there anything I need to fix? Have you made a digital classroom?

Welp that's it folks, see you next time! :3

😎Rad Rocket Animation😎

Hey Guys! Welcome Back!

Today we had to create an animation showing how rockets fly. I hope you like it! Here it is:

I hope you liked it!

Did you know how rockets fly? Did you learn something?

Welp, that's it folks, see you next time! :3

Spontaneous Simulated Finals

 Hey Guys! Welcome Back!

This is the final next ball game between Aus and Nz! What we had to do for this one is... we had an online die. There were some different types of die but I used a simple six sided die (try saying that 10 times fast). The rest is kinda explained on my screenshot... so here it is:

So we had to put the scores into a tally chart. They got 40 shots each (40 times to throw the ball into the hoop). A means Aus, N means Nz, G means Goal(s) and M means Miss(es).

So when I roll the die say I get a 6 that means it's a miss for Aus/Nz... for Nz they can get a goal if it rolls a 1-4, but it's a miss if it's 5-6... for Aus they can get a goal if it's 1-5, but it's a miss if it's 6. The reason this is unfair is because in the last challenge we found out their percentage of a chance of winning and Nz's chance was 66% and Aus's chance was 84%.

Then at the end we didn't get told to do this but I wrote down their shooting percentage... Nz is 50% (which is quite clear to see by their score) and Aus is 87.5%.

If you don't understand don't worry it's fine I didn't understand but then my dad helped explain it to me (I was home sick that's why my dad helped explain).

Did you understand? Was it interesting? You should have a go if you understand what to do.

So that's it folks, See you next time! :3

Nutty Nz vs Absurd Aus

Hey Guys! Welcome Back!

For maths we made 2 dice one was Aus and the other Nz. But before we did that we found (we used our brains and maths algorithms) the percentage of who is most likely to win a game between the two. Nz was 66% and Aus was 84%. Here is my table of the simulation match between the two.

The blue means that team won. As you can see they both won 2 games each. If you add their scores together Nz got 23 and Aus got 8. Even though Australia got a more likely chance of winning Nz still came to the top. I guess Australia were having a bad day.

You can also see that my predictions weren't that accurate especially the 20 shots each game.

Have you made a simulation of a sport game? Have you made a 6 sided die?

So that's it folks, See you next time! :3

Creative Capillary Action

 Hey Guys! Welcome Back!

This week we had another science report and experiment. Our teacher accidentally knocked over our experiment so my friend Jayde and I had to start again. But it's ok because we got a bigger container to fit it in. Here's my report:

Capillary Action

Questions:

How high can the liquid go up a stalk of celery?

Research Summary:

Ganesha, the Indian god, would get left milk at her shrine. But a man once tried to feed

Ganesha and found that the milk had disappeared. The scientists thought it was a celestial

intervention so they went to test their hypothesis and it turned out to be true, and it was capillary

action that made it happen.

The milk would flow through narrow cracks, with no assistance from an external force. So it

turned out that Ganesha was drinking the milk the whole time.

The science behind it is the Capillary action. Water can move up narrow cracks, tubes, straws

etc. You would expect gravity to pull it down but the adhesion, cohesion and surface tension

helps it climb up the side of the straw.

Hypothesis

I think that the celery will fade a bit as the liquid goes up.

Materials:

Water, red food colouring, beaker, sprite bottle and celery.

Procedure:

1. First, we got a beaker and filled it up with water (and added red dye).

2. Then we got a full stem of celery, marked it with a distance of 5cm each and then put it in the

water.

3. (Mr G knocked it over, so we had to start again) So we got a sprite bottle and cut the top off,

then filled it with the water and put the celery in.

4. We then observed and measured how far it went and how many days it took to get to that height.

Observations/Results:

Tests	Height	Speed
Observations	When we went to measure it we had found that the water had gone up to the leaves. We could tell by a red colour that was on the leaves, that looked kind of like veins. The height it went up to was 50cm.	We forgot to check on Friday and then couldn’t on Saturday and Sunday. So we checked on Monday which was the fourth day so it reached the leaves on the fourth day. Although since we didn’t check on the other days it could have reached the leaves earlier.

Discussion:

When we checked the celery stalk had faded a little bit but not that much, and when it got to the

top the leaves had thin lines of red in them like veins. I thought it was quite interesting how the

red water got up to the top in four days.

We couldn’t measure how far the liquid went day by day so we measured how far it went on the

fourth day and it had gone 50cm. I wasn’t that surprised that it went to the top in four days.

Conclusion:

I have learnt that capillary action can actually go pretty fast and high… well faster and higher than I expected. After doing this with celery I wondered what else it could go up and if it could go any higher than 50cm in four days… although we’d need it to be quite high.

Sorry but we don't have any pictures of this experiment :(

Have you done an experiment with a... fruit? vegetable? plant?

So that's it folks, See you next time! :3

Awesome Acids and Beautiful Bases

Hey Guys! Welcome Back!

Last week we wrote a science report on acids and bases. We also did a science experiment with them. Here is my report:

Acids and Bases

Questions:

What are acids and bases? What is the difference? What can acids and bases do?

Research Summary:

When you know an object is acidic it is under 7 on the scale and if it is basic it is over 7.

What is the difference? Well if an object is acidic then it will be able to burn/melt through other

objects. For instance, if it is 1 on the scale then that means it could burn through a table, and if it

was basic then it could not.

An example could be if you were to brush your teeth then after having a drink of juice. It wouldn’t

taste very nice because toothpaste is slightly acidic where as juice is basic. The bad taste

comes from the two neutralizing.

There are two elements that makeup water (H2O) which is Hydrogen and Oxygen. You may have

noticed that water that you drink at school or work may taste different from the water from the tap

at home. Why is this? Well it tastes different because in some water every part of the H2O may

be exactly how it’s supposed to be, 2 hydrogen and 1 oxygen. In times one of the hydrogen may

disconnect and float by itself, but then later joins another H2O and becomes H3O. That is why our

water may taste different from others.

Hypothesis:

When the two chemicals react, some will change to a different colour, while some may just stay

the same or lighten or darken.

Materials:

Beaker, Pipettes, Flask(?), Beaker Stand, Cabbage Juice, Sprite, Ammonia, White Vinegar,

Lemon Juice, Alcohol, Baking Soda.

Procedure:

1. Set aside the indicator solution. We used it as our "stock" solution for our experiments.

2. Secondly, we tested various household solutions with our indicator. We used one beaker for each

solution we want to test because we don’t want to mix chemicals that don’t go well together.

3. Then we placed an equal portion of indicator solution and the test liquid (e.g. Sprite) into a

beaker, we used a pipette to measure.

4. Next, we added drops of a liquid we wanted to test until we saw the solution change colour.

5. We then recorded what we had observed of the pH and a description of each solution we used

with the indicator solution.

Observations/Results:

Hypothesised pH	8	7	6	7	9	8
Estimated pH	5	11	4	3	6	8 & 10
Actual pH	3.29	11.6	2.5	2	7.3	8
Observed Colour	Light Purple	Dark Teal	Dark Pink	Magenta	Dark Purple (Slightly Lightened	Dark and Light Blue
Chemical/Product	Sprite	Ammonia	White Vinegar	Lemon Juice	Alcohol	Baking Soda

Dependent Variable(s):	Independent Variable(s):	Control Variables:
Colour Texture	Chemicals Cabbage Juice	Sprite: 2.5 x3 Ammonia: 2.5 x3 White Vinegar: 2.5 x3 Lemon Juice: 2.5 x3 Alcohol: 2.5 x3 Baking Soda: 1 teaspoon

Discussion:

I thought it was really cool and interesting how they changed colour and what colours they

changed too. Some of them I expected to adjust to that colour, but then others I didn’t.

When we did the baking soda, I thought it was fascinating how some of the Cabbage Juice

was soaked in by the baking soda and was turned into a light blue. Then there was the rest of

the Juice on top and was dark blue.

Conclusion:

My hypothesis was very accurate, and I learnt quite a bit. I thought it was interesting how each chemical had a very different texture and colour. I learned that when mixing a liquid with any household liquids can have a very different reaction (and that ammonia is deadly).

Here are some pictures of our experiment:

Have you done a science experiment before? If so how did it go?

So that's it folks, See you next time! :3

Super Samoan Greetings :3

Hey Guys! Welcome Back!

So today I had to make an animation of how to greet someone in Samoan. So here it is... I hope you like it! :3

I hope you learnt something!

Have you made an animation? Do you know how to speak Samoan?

So that's it folks! See you next time! :3
