Skittles 5 Senses

Kia Ora 
We did a Skittle experiment.  We got to take some Skittles, put them into a plastic plate and pour water around them.  My team made a smiley face  pattern with the Skittles.  The Skittles dissolved in the  water and it was like a rainbow.  We then used our  5 senses for Skittles writing.  Here is mine:

I see: The sight of the Skittles were cool. They looked like rainbows. We got a plastic plate and we dropped some Skittles in the plate and dipped them in some water and it made rainbow water.

I taste: The taste of  the yellow Skittles were like mint and ice cream. The brown Skittles tasted like chocolate, mint.

I hear: The sound of Skittles shaking, rattling and bouncing in the bag.

I feel: The Skittles felt like a egg shell and a rock.

I smell: The smell of the yellow Skittle is yellow lime and milk. The brown skittle smelled like chocolate and cookies.

5 sences

Kia ora.
We have been working on a Google docs about 5 senses. There is sight, taste, smell, feel and hear .We had to pick a picture and I chose an old hospital.
The old building feels like the walking dead.
The sounds are like zombies creeping around finding prey.
The walls feel like I’m the only survivor in the building.
The smell of the building is awful and the walls smell like stink bugs.
The taste of the air is like rotten flesh and disgusting eyeballs.

Cross Country

This week it was Cross country but I was sick so I stayed home. I hope everybody had fun and tried their very best. Here is a photo of kids from my class.

Science experiments.

This week we have done 2 scientific experiments so far. The first one was about floating and sinking and the second one was about fizzing and foaming. Here is a photo of me with my group.

Learning how to read scientific reports

Kia ora

We are learning how to read and write scientific reports. We have been doing experiments and writing about them. This is a reading activity we did. We had to be able to match a thesis with its hypothesis.

We are learning how to understand the structure and language of a report about a scientific experiment #3 Understanding that a hypothesis is a brainy prediction based on what you already know.
In this exercise you need to match a thesis with its hypothesis.  Use the ‘Fill tool’ to colour code the matching ideas.
                               Thesis                                                                      Hypothesis
I know this……                                                                         So therefore if I do this I think this will happen…
I know that a puddle of water is a small amount of water lying (usually) on the ground. I know that water is a substance which is found on our planet and that it can exist as a solid (ice), liquid or a gas (water vapour). I know that the main reason water changes from one state to another on Earth is because of  temperature -heat or cold. On Earth a sunny day is when there are no clouds, the sky is blue and the temperature is usually warm or hot.
I predict that when I mix vinegar and baking soda together that a chemical reaction will occur and that I will be able to notice this. I might feel hotness or coldness, notice smoke or bubbles, smell something, hear some kind of noise or  find that the taste or texture of the foods has changed.
I know that heavy things usually sink and light things float. However, container ships are heavy but they still float so there must be more things that have an effect on floating than just weight. Blutack is a squishy material that is quite light. It usually comes as a wide, flat strip but you can shape it into a round ball, a sausage shape, an O shape etc or you could flatten it out into a thin, wide shape like a leaf or saucer. Leaves usually float and ships look a little like a leaf shape.
I predict that when I take an ice cube out of a freezer it will begin to change back into liquid water (this is called melting) because it will no longer be colder than 0 degrees centigrade.
I know that an ice cube is water which is frozen. I know that that liquid water freezes into ice when the temperature reaches 0 degrees centigrade. An ice cube will stay an ice cube as long as it stays in a freezer.
I predict that if I make a puddle of water somewhere on the playground on a hot, dry day that the puddle will dry up and disappear quite quickly.
I know that everything we eat is made up of different kinds of chemicals.Sometimes when you mix different chemicals together they react with each other in different ways and the substances will do things that they didn’t do before (chemical reaction) and become different to what they were like before (chemical change). You will be able to notice things happening by using your 5 senses to  listen, smell, feel, look at and sometimes taste what is going on. I know that vinegar and baking soda are both food substances and I learned that they are chemically different
I predict that if I take some ice cubes out of a freezer and wrap them in different materials, I will find that one material will keep the ice cube frozen for longer than the others. This material would then have proven itself to be the best insulator.
I know that liquid water changes into a solid (ice) when the temperature reaches 0 degrees centigrade. I know that a freezer will keep water solid because a freezer’s job is to keep food at a temperature just below 0 degrees centigrade.
We are going to use Bluetack as our material. We will use the same amount of Blutack to make three different shapes. One will be a straight, rectangular strip of Blutack, one will be a compact, round ball and the third will be a rounded  saucer shape like a boat. We predict that at least one of these will float.
I know that insulators are materials that can be used to protect yourself from too much heat or cold. When we put clothes on because we are cold, the clothes are insulators which help our bodies stay warm. If you put insulating material like Pink Batts in the ceiling of your house, in the winter the Batts help keep warm air inside the house. In the summer, The Pink Batts help stop hot air coming into the house so they help to keep us cool. Many  food containers like Thermos flasks and Chilly Bins are made out of insulating materials to keep food hot or cold.
I predict that when I put some liquid water into a freezer it will change from a liquid state into a solid state (ice) because the temperature in the freezer will be below 0 degrees centigrade.

Our science experiments

Kia ora
We are having a science fair this term so we needed to learn how to write a report about a scientific experiment. Our teachers chopped a piece of scientific writing into bits and we had to sort them out into the right order. We had to match the structure clues with the correct sentences and paragraphs. It was tricky. When we were finished we used the report to carry out a floating and sinking experiment using Blutack.The Blutack wouldn’t float unless we squeezed  it into the shape of a boat. It was fun. Here is a picture.

Learning how to read and write scientific reports.

Kia ora

We are learning how to read and write scientific reports. We have been doing experiments and writing about them. This is a reading activity we did. We had to be able to match a title for a report with a wondering question.

Freezing Water.
What will happen when you mix vinegar and baking soda?
Floating and Sinking.
What will happen to an ice cube if you take it out of the freezer?
Kitchen Chemistry.
Which materials make the best insulators?
Disappearing Water.
What happens when you put a container of water into a freezer?
Keep Your Cool.
What will happen to a puddle of water on a hot day?
Ice Cube Experiment.
Does Blutack float?
