Science/Aerodynamic.

Aim: To learn about flight and aerodynamics.

• In your groups of 3 you will make a paper plane and measure its distance and behaviour.
• In groups of 3 you will make a water rocket and record its distance and behaviour.

Definition:

4 forces of flight:

1.  Thrust.
2.   Gravity.
3.  Lift.
4.  Drag.

Paper Plane:

Material: Piece of Paper

1. Fold it &

2. Fold it again

Steps:

1. Length the paper.

2. Fold the corners.

3. Fold the paper again then fold the corners again is well.

Findings:

Plane Type	Distance	Behaviour
Normal	5m	Straight
Ailerons	3m	Straight
Paper clip	5m	Straight

Conclusion:

We found that the normal plane flew straight for 5 metres. Secondly the Ailerons also directed straight as well and it flew 3 metres. Also with using the paper clip, the paper plane flew 5 metres and it flew straight but curved a little bit.

Here are some words and parts of a plane I have learned. What I have learned about thrust is that thrust directs the plane to where it is going, so if the captain turns the wheel to the left then the thrust will direct the plane to the left. Secondly I have learned lots about Gravity. For example, if you throw a pen up, it will come back down, that is Gravity, but if you are in space you can bounce around and fly because there is no Gravity in space and also in earth there is 100% of Gravity. The word i’ve also learned in science is Lift. Lift is the same thing as a elevator, so when you are in air the lift helps the plane stay in the air. Thirdly i’ve learned the word drag, drag is a force that holds the plane back when the plane is driving.

Overall i think this experiment was great. It was fun creating planes and learning the word Aerodynamic. I could be able try this out at home. Thankyou for reading my amazing blog post have a good day.

My mihi

Kiora my name is Aisa and I have been practicing my mihi for this year...

• Tena Koutou Katoa,

• No Samoa ahau.

• Kei New Zealand toku Kainga inaianei.

• Ko Hornby high Toku Kura.

• Ko Mataese toku Whanau.

• Ko Vai M toku Matua.

No reira, Tena Koutou, Tena Koutou Tena tatou Katoa.

Home chemistry science/Balloon

Aim: To see which chemical

the mix creates the most gas.

Hypothesis: (What do I think will happen)

I think that the vinegar will not make the balloon go up or will not make it go higher,  so I think that the other 3 teaspoons of baking soda will make the reaction better and more fluent.

Materials:

1. Vinegar
2. Bottle
3. Balloon
4. Baking soda
5. Soda
6. Salt

Steps:

1. Measure half a cup of vinegar then pour it into the bottle.
2. Then you will need to measure three tea spoons of baking Soda then tip it into the bottle.
3. Then you need to pour half a cup of soda.
4. Then you need to get do three tea spoons of Salt.
5. Blow the balloon up then put the balloon at the top of the bottle.
6. Secondly you shake the bottle a little bit to get the bubbles pumping
7. Then the balloon will start to blow up.
8. Then you measure one balloon to the other.

My images:

Findings:

	Balloon 1 ( 3 tsp baking soda, ½ cup vinegar)	Balloon 2 ( 3 tsp salt, ½ cup soda)
Balloon Size (cm)	8 cm	4 cm
Bubbles (small, medium, large)	large	small

Home chemistry science.

Home Chemistry: Introduction

Aim: To learn the names of 10 household chemicals, their elements, and reactions with other substances.

Equipment:

1. Dish washing Detergent

2. Lemon

3. Salt

4. Vinegar

5. Sugar

6. Air Freshener

7. Onion

8. Lemonade

9. Bleach

10. Baking Soda

11. Milk

Step 1: We had to get into a group of three

Step 2: Then we had to get the filter paper with the water-based pens

Step 3: After that, we had to get a ruler and a pencil and draw a line then put two dots of water-based colored pens

Step 4: then we put the filter paper in the cup and put about 1cm water into it you will need to tilt the cup so when you tilt it the water must hit the line for it to work

Step 5: Then after we took pictures and blogged about what we needed and did we showed the teacher

Step 6: and then you can move onto the next science activity

Task 1: Put the chemicals in a chart with the titles: Name, Chemical ingredient(s), Image, Solid/Liquid/Gas.

Steps:

Name	Chemical ingredient(s)	Image	Solid/Liquid/Gas
Salt	Sodium chloride		Solid
Lemon	3 large eggs. 1 cup sugar. 1/2 cup lemon juice about 2 lemons. 1/4 cup butter, cubed. 1 tablespoon grated lemon zest.		Liquid
Onion	1.1 large onion, cut into 1/4-inch slices. 2. 1 1/4 cups all-purpose flour. 3. 1 teaspoon baking powder. 4. 1 teaspoon salt. 5. 1 egg.		Liquid/gas/solid
Vinegar	Vinegar is made through the involving of ethanol alcohol. Any ingredient containing ethanol may be used to make vinegar, including distilled grain alcohol, wine, champagne,beer, cider and more.		Liquid
Sugar	Invert sugar. Corn Syrup. High Fructose Corn Syrup. Description. White crystals or powder.		Solid
Milk	Whole Milk, Pure Cane Sugar, Miaroma Chocolate Power w/ Pure Vanilla (Processed with Alkali, Starch, Salt, Carrageenan, Pure Vanilla, Vitamin D3 added).		Liquid
Baking Soda			Solid/Liquid/Gas
Lemonade	cup white, granulated sugar (can reduce to 3/4 cup) 1 cup water (for the simple syrup) 1 cup lemon juice. 2 to 3 cups cold water		Liquid/Solid
Air Freshener	3/4 cup water (I use tap water, but distilled is fine too) 2 tablespoons vodka, rubbing alcohol, or real vanilla extract. One of the essential oil combinations below.		Solid
Bleach	While pure chlorine gas will bleach colors, in laundry bleaches, sodium hypocrite or calcium hypocrite are actually used, and they work by releasing oxygen, not chlorine.		Solid/Liquid/Solid

Conclusion:
What i think about chemistry science is that it helps people learn about these items and what is in them. Also i think that it helps people understand why lemon is sweet and why the items have ingredients.
