Hi guys, today I am going to share a DLO I have done. I have made a poster about how to be healthy and stay healthy. So in my poster, I have written down a poem about being healthy. it goes like this
If you feel tired
If you feel blue
If you don't know what's wrong with you 
Get up and move
Get in the groove
Exercise and you will improve.

What do you think about that poem? Anyway here is my poster. BYE

Forensic Science

Forensic Science

1. Write the definition of forensic science in your own words?

Scientific tests or techniques used

https://en.oxforddictionaries.com/definition/forensic

2. What are the 5 different things that forensic scientists do?    Look at the "What you will do" section on the careers NZ website.

1. Forensic scientists go to crime and take notes and drawing of a crime scene. 

2. They also find pieces of evidence

3. Give the pieces of evidence to the court.    

Fingerprints

Aim: To look at the different types of fingerprints.

Materials: 

1.   Balloon 
2.   A humans finger
3.   Inkpad

Steps

1. Get a human finger  
2. Dip it in the ink pad   
3. Then wait 5 seconds   
4. Take your finger off the ink pad and put it on the balloon. Make sure the balloon is not blown up.     
5. let it dry
6. Next, blow your balloon up   
7. Then see what type of fingerprint do you have? Do you have an Arch, Loop or Whorl?    

Record the types of fingerprints from those in your group.

Name	Fingerprint 1 (Thumb)	Fingerprint 2 (index finger)
Elisha Mae	Whorl	Arch
And ME, Risha	Whorl	loop

Questions:

Do people always have the same type of fingerprint on their thumb and index finger? No, because every finger is different. 

What was the most common type of fingerprint in your group? Whorl 

Hidden fingerprints:

Aim: To learn how to lift hidden fingerprints from an object.

1. Lifting and Gathering fingerprints.

Equipment:

1.  A  makeup brush 
2.   Baby powder 
3.   Clear thin paper
4. tape
5.   A human finger
6. black cardboard

Method: 

1.  Get your thin piece of clear paper and put your finger on it 
2.   Wait for 1 minute then take your finger off it   
3.   Get your brush and dip it into the baby powder. 
4.  Then with the brush lightly brush the powder onto the thin clear paper 
5.  Then shake off the excess 
6. Then take your tape and put it on top of fingerprint that is on the thin clear paper.
7. Then peel the tape and put it on the black cardboard.

Conclusion Questions:

Did you manage to lift clear fingerprints?

What could you do to improve your results next time?

Why do you think fingerprints are useful to crime scene investigators?

Hey guys, today I am showing the work that I did. It is called "Learning Story." It is sort of like a report but we are writing it about our self. I did mine about my favourite experiment. Which was "Filtration experiment." Anyway here is my "learning story." 

In science for this term, we have been learning Home Chemistry. Also have done some awesome experiments like scone making, forming crystals, skittles colours but my favourite was the filtration experiment or the dirty water experiment.

 

Our aim for this experiment was “to make a filtration plant using household materials. The meaning of filtration is when we separate a solid into a liquid.  

We had to work in teams in my team there was Neveah, Shreya, Elisha Mea and I. The materials we needed to do this experiment was one plastic bottle, sand,  pebbles, dirty water, scissor, filter paper, a cup and tissue paper. My favourite part is how we made this experiment.

We first had to cut the bottle in half to make a plastic funnel and a container that the dirty water will go through. Then put the top half upside down on the bottom half. After that add a layer of filter paper. I suggest that you should fold it in quarters then unfold to make a cone shape. I had thought about folding it once more because I didn’t think it would work so did my team. In a result, we were the only team with the cleanest water. YEAH! Then we put some sand inside the cone and place it in the funnel. After that add your one cup of pebbles on top of the sand. Then it is time to add in your 1 cup of dirty water.

My conclusion is that we had the best example of how we did this experiment.  We all had a job and we all liked the job we did. We also all knew what our next steps were and we all completed our work in time. I think that when we had folded the filter paper again was a great idea and made our experiment the best experiment.

Mars - How to get to Mars

Aim: To design and build a Mars Rover using  Lego Technics.

1. Rover facts
2. Design and make draw Rover
3. Mars facts

Research links:
Mission to Mars - NASA
Mars rover view

Information about Rovers 5 parts

1. Rover facts

Why do we have each of the parts?

Fill in the table below.

Name: Risha	Purpose:
Wheels	The rovers have wheels so they can explorer more about mars. Rover also have wheels because then they can take photos of mars.
Solar Panel	They have solar panels to get energy from the sun. That energy helps the rover move around and do what it is suppose to do.
Laser	The laser is for detecting things in the distance. So they are like a sensor to see something far away. They are like Eyes.
Camera	The rover has a camera for taking photos. Those photo go on to a computer so people on earth examine it.
Shovel, rock pick,drill	If it see's a big rocks it will examine it and maybe even break it and see whats in there. With that drill or shovel or rock pick.

Mars Rover details:

2. Make a Mars Rover that has the following:

• 6 wheels
• 1 camera
• 1 shovel, rock pick, at the front
• 1 solar panel
• 1 laser that points at the ground

 ( Upload a photo of your mars rover onto your blog.)

3. Mars Facts

You will need to find out the following:

Fact	Earth	Mars
Picture of planet
Length of 1 year	365 days	687 days
Length of 1 day	24 hours	24 - h 37 - m
Distance from the sun	149.6 million km	227.9 million km
Distance from Earth.	92,955,807 miles	54.6 million kilometres
Gravity:	9.807 M/S 2	3.711 M/S 2
Colour:	Green, Blue and white	Red and grey
Temperature	-88 to 57 C	196 degrees F
Rainfall	600-1,600 millimetres per year	It doesn't rain in mars because the Temperature is low and pressures mean water can only exist as vapour or ice.
Atmosphere	Earth does not directly share a name with an ancient roman. Earth is not perfect sphere	Mars Atmosphere is 100 times thinner than earth There is about 95.3 %  of carbon dioxide.
Surface	Land and cloud Ocean	Desert Rocky
Moons and names	Moon	Phobos Deimos

Extra for experts
Draw your mars rover. Clearly label each part.

MATHS TIMES

MATHS TIMES

Hi guys to I am going to be writing about what type of trucks drive down Waterloo road at 11.50 am to 12 pm. Lets go.

So today I made a graph showing how much trucks go down Waterloo road at 11.50 am to 12 pm. Here is my work.  

So in this graph you can see that the most trucks gone past were UTE's. There was three types of trucks that didn't go down the road. The second most largest row was the truck and trailer row. 

  

What is that white powder?

Today you will be a forensic chemist. 

A bag of white powder has been confiscated by the airport customs.  You need to find out what white powder it is?

Aim: To learn about the makeup of different white powders.

There are  a number of different white powders in our everyday life. Some of these are harmful and others are not. Test the four white powders listed to see which one has been found at the airport.

Here are some examples of everyday kitchen white powders.

Flour, Cornflour, Sugar, Salt, Baking Soda, Baking Powder, Icing Sugar, Tartaric Acid

Citric Acid, Gluten Free flour

You will be given a small amount of 4 white powders on your cardboard. On the black cardboard using a magnifying glass look at the powders.

Look at them under your magnifying glass and record what you see. 

These are the four powders we will be using. Upload a photo of each powder. 

1.  Cornflour
2.  Baking Soda
3.  Salt
4.  Sugar 

Before you add the iodine, vinegar or water you will need to divide each powder into 3.

Materials

1.   Cornflour
2.   Baking Soda 
3.   Salt
4.   Sugar 
5.   Magnifying glass
6.   Iodine
7.   Vinegar

8.   Water

9.   Tea Spoon 

10. Pipette 

11. Black Paper
Steps

1.  Add in half of the sugar in to one part of the paper
2.  Then do that to all the other powders
3.   Put each powder into three groups
4.  Add in 4 drops of water into on of each powder group
5.   Then add in 4 drops of water into each powder group
6.   Then add in 4 drops of vinegar into each powder group
7.Then add in 4 drops of a Iodine into each powder group
8.  See what happen's!

Findings:

	Sugar	Salt	Baking Soda	Cornflour
Appearance	Cube and white also Crystals	Cube and white also Crystals	Fluffy, White	Fluffy and cloudy
Tex ture	Larger Grainy	Grainy	Soft	Soft and Fluffy
Smell	Sweet	Salty	Like clay	Nothing
Iodine	Crystals  Brown sugar	Crystals  and Yellow	Like ear wax	Black and white hard
Water	Sugar water	Salt water	Fizzing and hard and wet	Oobleck
Vinegar	Wet sugar	wet salt	Fizzing	Oobleck

In this experiment I found out that if you add in vinegar to cornflour it makes Oobleck. Well kind of! I thought that it would only make Oobleck with cornflour and water but it can be made with vinegar as well. Anyway I found out that if you put Iodine with salt they look like crystal. Cool!
