Book review

The book I am reviewing is Hoot by Carl Hiaasen.

Hoot is about a boy called Roy who has moved from Montana to Florida. He gets bullied by Dana Matherson but if Dana had not pressed Roys head against the bus window, Roy would never have seen a strange boy running barefooted.

The story is basically a question. Will Roy meet the boy?

My favorite part so far has been when Beatrice the Bear tells Roy she knows the barefooted kid because he is her brother.

I would recommend this book to people who like mystery. Hoot is a very good book and is a great read. I rate it so far a 8/10.

Buddy Time

Every Friday my class goes to see our Buddies in Room 5. I share a Buddy with my friend Emily. Our Buddy's name is Lucy. I really enjoy my time with Lucy because she is so nice and is always eager to see me. During Buddy time we do many different things. Last time I went we did their portfolios. We also read to them, do Jump Jam with them, help them with their spelling and if we are lucky, art. I sometimes find it hard to control Lucy because she is a very independent girl. But despite that, Buddy time is always a look forward to.

Maths sample

This is a recent basic facts test that I did. I recently moved to the top maths class so my booklet is different to the others. My record is to do one hundred equations with a time of 2:43.

Handwriting sample

This is an example of some handwriting that I did earlier today. Olivia Seymour and me marked my work.

Introduction:

What is best for removing stains, washing detergent or home solutions?

I decided to do this experiment to see which removal product works best. I started to think to think which stain removers I could use when I thought of what they did in the 1900s. They used home solutions. So I looked through Aunt Daisys book of handy hints and found the coffee stain remover and then my project had really begun.

Hypothesis:

My hypothesis is that the washing detergent will be better because the washing detergent might work better on dry stains. The home solution will probably not work as good.

Planning a fair test:

Unfortunately, I have to change two factors.
The two factors I am going to change are:

1.The type of stain remover:
Aunt Daisys stain remover
Surf Washing detergent

2.The recipes for:
The home solution recipe
The Washing detergent recipe


The factors I am going to keep are:

1. The size of the material
2. The type of material
3. The amount of coffee spilt on the material
4. The amount of time left to soak
5. The amount of time left to dry
6. The amount of water and Glycerine

Results:


The result were that the Surf was slightly better than the Glycerine.

Surf material:

Sight: The material was really close to having removed the stain completely.
Smell: The smell is completely gone.
Feel: The normal material is softer than it.

Glycerine material:


Sight: Looks like it is halfway from finishing.
Smell: Slight coffee smell.
Feel: It feels wet.


Conclusion:


My data tells me that Modern Technology (Surf) was better than the Old Solution (Glycerine). The Surf  
was slightly better than the Glycerine

What is the Carbon Cycle?

You are probably wondering what is Carbon? What do we have to do with the Carbon Cycle? And where can we find it? Here is where you can find your answers. The Carbon Cycle is made up of many different parts. Some being Respiration and Photosynthesis. Carbon can be found anywhere. Some things store it (Plants, humans, animals, rocks, trees, shells and fossil fuels), some make oxygen (Trees and plants) and some (Lakes, rivers and the ocean) dissolve it.

When you breath out you remove oxygen from the air. When you breath out, you release Carbon Dioxide into the air. But not only you, animals and fish do it too. But plants and trees help us turn the Carbon Dioxide back to oxygen. Plants take in Carbon Dioxide and release oxygen. Trees do the same and they both store Carbon Dioxide too.

Photosynthesis is how we get clean air. Land plants and trees are a part of the photosynthesis process, but under the water, ocean animals and plants are doing their part in the photosynthesis process too. Like I said before, Carbon Dioxide gets dissolved in water. Ocean plants store the dissolved Carbon Dioxide and when the ocean animals eat the plants they get some of that Carbon Dioxide to store too. Ocean plants also turn the dissolved Carbon Dioxide back into oxygen. Some sea creatures even use Carbon to make their shells and when they die, their shells dissolve again.

When a plant or a animal dies it releases all of the Carbon it has stored in its life. Then wherever it's left, it starts to decompose and slowly become part of the soil beneath it. After a long period of time the decomposed plants or animals compact and could become fossil fuels. Such as Coal, Oil or Gas.

Humans make a lot of Carbon Dioxide. Did you know we breath at least five litres of air a minute ! Thats a lot of Carbon Dioxide! But there are lots of other things we do that produce Carbon. Like when we burn trees, use cars or have factories. They all produce Carbon. Also we when we die we release all of the Carbon we have stored.

In conclusion, the Carbon Cycle is very important to the way we live. But it is not just us that makes Carbon, so even if humans never existed, there would still be a Carbon Cycle.
