Popcorn writing

Hello fellow bloggers.
The week before last week were doing an experiment with popcorn and used our five senses. We got to touch,hear,look, smell and taste the popcorn. After our experiment was a success we had to write about it using our five senses . I decided to do a Google draw to share my work.

Here it is:

Raw meat poem / Lamb heart writing

Kia Ora Everyone.
Yesterday we were observing animal body parts. But first we got put into groups, My group was: Mosese,Indi,Honey and Depla. We got given a piece of paper and it had our five senses on it. We got given a lamb heart. We observed it and poked it. Then we had to cut it open to observe the inside. After that we got to cook it. I didn't want to eat it so I went outside and today we got to choose any kind of DLO to share our writing.

Anyways, here is my poem.

Skittles writting

Kia Ora bloggers
This week we have been doing an experiment based on Skittles using our five senses Touch, Taste,Hear,Sight and Smell. We placed the Skittles in a bowl filled with warm water and watched them dissolve. When that was done we got to write about the Skittles.

Here is my writing:

The Summer Breeze!!

Kia ora bloggers. This week we have been doing our five census feeling, taste, smell, touch and sight. We had to write our own sentences about them and choose an image. I choose the beach.

Here is my writing.

The Summer Breeze

The boiling hot sand started to tingle under my foot as I placed it roughly.

The sight of the sun blinded me as I was relaxing on my stripy towel.

I spotted the palm trees dancing side to side ready to enter a ballet contest.

My skin started to shiver up my spine when I ran into the deep blue sea.

Hearing the monstrous waves made me shiver and scared.

The taste of a coconut made my taste buds pop like popping popcorn machine.

I touched the blue dolphin as I dived searching  for some lost treasure.

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 it's 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.

Foaming and Fizzing

Kia Ora bloggers.
This week, we did an science experiment called 'Foaming and Fizzing'. What we had to do was taste vinegar and baking soda individually and see if they have different taste, then we had to write a report with a title, question, thesis and much more. When we finished the report half way we got to mix the vinegar and baking soda together and taste it.

Here is the report.

Yuk and Yum !

If we mix vinegar and baking soda together will we observe some kind of reaction?
Vinegar tastes sour and it is a liquid. Baking soda is a solid, soft white powder and it tastes salty and horrible. They are food substances but based on their different taste, they must be chemically different. So, if they are mixed together, there might be a chemical reaction.
We predict that when we mix vinegar with baking soda an observable chemical reaction will occur. We might see and hear an explosion, fire, foaming, bubble, fizzing or something else. The resulting mixture might look and taste different. There might even be a different in the size of the materials.

Baking soda
Container for mixing
Teaspoon for mixing

Step 1: Pour some vinegar into a container to a depth of about 2cm.
Step 2:Use a teaspoon to measure in half a teaspoon of baking soda.
Step 3:Mix with teaspoon.
Step 4: Observe and record what happens.
At Step 2 the mixture started to fizz. A fizzing sound was heard, bubbles were seen to appear in the mixture and the materials rose higher in the container.
At Step 3 , when the materials were mixed, even more bubbles appeared and the volume of the materials in the container rose even higher. When the mixture was tasted, The taste was unpleasant and was similar to  baking soda.  

The goal of experiment was to see if an observable reaction would take place when vinegar and baking soda were mixed together. The result of our experiment proves that our hypothesis was correct. We predicted that there would be an observable reaction, and there was. There was lots of foaming and fizzing happening and bubbles appeared which mean a gas must have been produced. A quick check online showed us that the gas was carbon dioxide.

Science writing

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.
