Finger prints

Fingerprint characteristics

Aim: To look at the different types of fingerprints.

Materials: 

1.   Fingers'
2.  Inc pad 
3.   Balloon

Steps  

1. Get the inc pad and the balloon ready   
2. Put your thumb in the inc and then press on the balloon lightly   
3. You then blow up the balloon  and then deflate it again
4. Do the same but with your index finger   
5. Blow the balloon up and tie it  

Conclusion: This was a very cool experiment because we found out what fingerprint we had , even tho many people had the same they are all different in their own was , in this experiment I found out I have an arch fingerprint.

Lifting fingerprints

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

1. Lifting and Gathering fingerprints.

Equipment:

1.   Brush
2.   Plastic
3.  Baby powder 
4. Tape  
5.   Finger
6. Black card 
7. Magnifying glass 

Method: 

1. Get your plastic, brush, and baby powder
2.   Press hard  on the plastic to create a fingerprint
3.   Get the powder and brush some powder powder onto your fingerprint
4. Cut a small piece of tape and put it on the fingerprint
5. then put the tape on the black cardboard to revel  what type of fingerprint you have 

Results:

Lifted fingerprints

Conclusion:In conclusion it was really fun and it has been really interesting and 

something I could do next time to make it better is being more steady when I am pressing on the plastic , I think fingerprints are handy because it helps investigators with who the criminal is and where they have been.

Physical well being

This week in drama we have been talking about exercise and healthy eating and how our well being is. We played a few games today they were 7UP and Tequila . This was a very fun moving activity and it got us energized , we also looked at what laughing yoga , this was a very fun activity and it was also really funny to try and do because why u fake laughed you ended up laughing because everybody was making funny noises.

I will now answer so questions about my physical well being.

How does exercise effect your body?
Exercise effects the body in a good way by making you get up and do some physical activity like running , walking , bike riding , even just playing outside with your siblings .

What fitness do I currently do?
Walk from school and sometimes to school , walk to the mall , play netball , most of my physical activity is walking.

My goal for this week?
Go for a walk everyday and try to have a healthy breakfast everyday

How am I going with this goal?
So far I have gone for at least a half and hour walk everyday and with the healthy breakfast thing that's not going to well for the moment but it will be throughout this week.

Somewhere I can achieve my goal?
Halswall Quarry , Here is the map :

Maths DLO

Today I will be sharing my math's DLO with you , I did a slide that shows what we did so here it is ......

Rainbow paper

 

Aim: To separate colours by using the process of chromatography.

Materials: 

1. Filter paper
2. Water based felt pens.
3. Plastic cup
4. Water

Steps:

1. Come and collect your sheet of filter paper.
2. Then we had to measure a line 1 cm from the bottom of the paper.
3. Then make two different coloured dots with felt pen on the line and get the teacher to add a very little amount of water.
4. Then see what happens to the dots.

Conclusion:

We found out that the colours mixed together and slowly rose to the top of the paper. We also found out that the blue felt moved faster than the purple as you can see in the picture even though they went into the water at the same time. I found it interesting how they both mixed then separated. Working in a team of three was easier than by myself .

Community Impact Projects

 I have joined the  Christchurch Ōtautahi Community for our (C)community (I)mpact (P)rojects.

This is my passion because our group feels like there is somebody or some people  out there who needs our help around our community that need things more than I do. 

I am interested in helping the people that are in need of things, like food and water and things that keep you clean and warm.

I think we are going to achieve this by making fundraisers to raise the money for it , I would achive this by writing a formal letter to our principle asking for a mufti day I will then be going to our principle if he approves me letter.
