Over the past week the grade 6s have been working on designing a solar boat. Today we had to create a smaller version of our boat design. We then had to test our boat for alignment, balance, speed, flotation, symmetry and the creativity of our design. Here is my test results:
My test hull:
Crop circles, what are they and how are they made so quickly?
Well, how are they made so quick! Did you know that crop circles are made overnight. And some of the designs are incredible. To find some amazing crop circle pics, type into images: crop circles. And you can see some REAL LIFE crop circles from a birds eye view. It is really amazing how they can finish it just in one night! And people say that you can make one with a piece of rope! You can go to this http://www.coolmath.com/lesson-geometry-of-crop-circles-1.html website to find out more info on crop circles.
We got to make own crop circle. Firstly we had to find out information about the geometry of crop circles.
What does geometry mean/stand for?
Then we got design our crop circle, after that we had to a crop circle analysis. Here is my Crop Circle analysis. After we had finished that we had to make another crop circle on a word doc. Here is my Crop circle design.
Here are some pictures of crop circles I made:
This is my coloured in crop circle design. It includes straight lines, circles and triangles.
This is my grey led crop circle design. It includes triangles, circles and straight lines
Here are three draft crop circles. I chose the one on the right as my design.
My class and 5A has done a shoe investigation. We had to find out the length, area, perimeter and width of our shoe. We had to make a grid with an out line of our shoe then find out the length, area, perimeter and width of our shoe. Then we had to count the squares (1cmx1cm) and colour them in and label each section of colour with how many squares there are.
Here is half of my shoe grid which has the width, area, length and perimeter.
Here is the other half of my shoe grid which has my area, length, perimeter and width.
The grade 5s have been investigating the worlds top 10 tallest buildings. We have been (of course) finding out what the top 10 tallest buildings are, making graphs and finding out all the other information about the buildings .5C talked about predictions.My class had to predict what we thought about the buildings. From where they are in the world to how tall they are. My prediction is: That Tokyo, Australia, America, Turkey, India, Egypt, Dubai and Egypt. will have the top 10 tallest buildings, because they are all wealthy countries or a rich/grand history. I also think that they will be evenly spread. I think that all of the buildings will at least be 600M tall. I think this, because (for example) Dubai is wealthy. We had to make an excel document with our raw data and three graphs. We also make a pictograph.
Do you know what an pictograph is?
Here is my Excel doc and my Pictograph
Our class has been learning about pentominoes.
Are you wondering what pentominoes are?
- Pentominoes are a shape made out of 5 squares.
- You can’t call a flipped over pentominoe a new one.
- A pentominoe has to touch edges not corners.
My class had to find out if they had the same area and perimeter.
This is the definition of area and perimeter.
Area: Space inside a shape or object. It’s measured in cm2. The formula is L X W = A
Perimeter: The length of the outside of a shape.
L + L + W + W = P.
We also had to have a Hypothesis. My Hypothesis is: I don’t think they are going to be the same, because the space is and looks bigger on the outside and they are different shapes and sizes.
I was right. All of the shapes have a perimeter of 12cm2 except one, which has a perimeter of 10cm2. So not all of the shapes are have the same perimeter, but they all have the same area.
This game has a grid where you have to put pentominoes on the grid to fill the whole grid. You can flip, rotate and turn the pentominoes to fit the grid.
What do you know about pentominoes?
