We continued our investigation into the different materials and its properties.
This week we found out that unlike the fabric silk and wool which are natural materials and come from animals, there are other natural fabrics like cotton and jute that come from plants.
We looked at how cotton grows and then is spun into threads which get woven into fabric.
We did not have machines but we used our hands to try and spin the cotton into thread.
At first the cotton ball was soft and could break and come apart easily. Once it was spun into a thread it become strong and difficult to pull apart. Since it was soft we used it to make clothes. We also found out that we should wear clothes made of cotton in warm countries since it keeps us cool.
Sorting the 3D shapes in the class.
Visit to the Grade 5 Exhibition:
Loads of fun showing our parents what we learn in class during the Student Led Conference!
Shapes all around!
This week we started looking at 3D shapes. We discovered that we are surrounded by 3D shapes. Some were:
Cube: Dice, ice, box, blocks
Cone: Ice cream cone, party hat, traffic cone, mountain
Cylinder: Pole, pipe, straw, arm, marker
Sphere: Ball, globe, earth, moon, sun, eyeball, marbles
Pyramid: Pyramids in Egypt, roof, desert
Rectangular prism: Eraser, bus, soap bar, buildings, sponge, trolley, chocolate bar
Triangular prism: Tent, ramp, roof, slide
When do we use a question mark? During Daily 5 we looked at words that could be used to ask questions. We also looked at the symbol of the question mark and used it in our writing.
Properties of materials:
Bend it, squash it, stretch it, bang it! We discovered that materials feel, look and sound different! There were so many different ways in which we could describe the material.
We have also started wondering why we should use a particular material to make things!
We are being inquirers and thinkers! During our show and tell we are carefully looking at the materials and investigating if they are natural or manufactured.
Zoe and Reika got objects that were made of fabric. Some of us thought that all fabric came from animals. So we started our investigation into where fabric came from?
Ceyone researched and found that silk came from silkworms!
Did you know that a single thread of silk could lift 2 students from K2 without snapping? Silk is very strong and light that is why it is used in making parachute!
Natural material or not?
What is a natural material? We discovered that materials that are found on the earth, or that which grow on earth, are natural materials. They are plants, rocks, water. Lots of other materials and not found in nature. We wondered what these materials that were not natural, but made by people, called? We thought of several names:
We thought that plastic and sponge were human made materials. We continue to investigate and inquire into other man made materials.
We then went on a hunt in our playground to find things that are made from natural materials and those that are human made materials.
Things made from natural materials:
Things made from manmade materials:
Properties: Finding out more about the materials, we looked at it closely and thought about what it looked like and felt like. These are some of the words that we came up with: shiny, hard, soft, spiky, breakable, reflective, see through, waterproof, bendable.
During Daily 5, we continued to focus on using describing words. We looked at some natural materials and described them by how they looked and felt.
Shapes and symmetry
Symmetry: it is when one half is the same as the other half.
When a line cut an object so that the 2 parts are the same, is called the line of symmetry.
K2's very first student nominated certificate to Anjali!
This week we have been focusing on using describing words to improve our writing and speaking skills. We continue to work on our reading, writing and spelling skills.
There are lots of shapes with 4 sides, how do we differentiate? We found that
Rectangle has 2 long and 2 short sides
Square has sides which are all same
Trapezoid has two slanting sides, one short and one long side
Rhombus looks like a diamond
We are surrounded by lots of materials! We sorted materials into different categories.
Later we were given chocolate to make teapot, plastic to make dress, paper to make shoes and wire to make umbrella. Were these suitable?
