Home Chemistry: Forensics? The White Powders

Today you will be a Forensic Chemist. 

A bag of white powder has been confiscated by 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.

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. 

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.  Pipette
2.  Paper/cardboard
3.  Iodine

Steps

1. Fold the piece of cardboard/paper into 4.
2. Write 4 Chemicals on the 4 folded squares. 
3. Put 4  Chemicals on 4 folded squares and split them into 3.
4. 3 drops of Iodine/Water/Vinegar into a third of each chemical

Findings:

	Sugar	Salt	Baking Soda	Cornflour
Appearance	A light white	Harder white	White	Soft
Texture	Hard, Soft? Wetish	Hard, Soft?	Hard	Smoothish
Smell	Sweet	Salty	Smoothe	Dusty
Iodine	Darker orange color	Turned darker and wet	made it turn orange as well	Made a dark purple and tiny bit of pink.
Water	Silky white	Silky water	Wet	Slim, wet
Vinegar	White Wet	wet	Fixed up	Rolled of could not get wet.

Conclusion: Today I learned about what happens to the four powders when the powders have interfered with the chemicals, Water, Vinegar & Iodine. and how to tell is one powder is the other for ( Example: Laying out powder and then putting a liquid like Iodine, Vinegar or water on it one by one and seeing what the outcome is, and then see what type of powder it is that will change differently, This is basically what we did for experimenting on white powders, We tried to tell what powder was which, How exactly? with some liquids...   

Science: Forensic/Home Chemistry

This weeks blog for science is mostly about forensic but we are learning today so let me tell you guys, about some of the work we have done, my group for today was Ryan, Christian, Lasa & myself.

Aim: The aim today is to see what the water-based pens will do to our or with the paper and what we tried to do was to get a reasonable result it was basically a mystery to see what would happen,

Materials/Steps: Our materials were
Paper,
Water base pen,
Plastic cup,
1. we used the filter paper for the color to stream up to its destination
2. The pens were for the color first we had a little strip of filter paper
3. we put the little paper on the cup with the bottom part on the inside of the plastic cup,
4. Then we lined two dots 1cm from the bottom and then we filled it up with a little bit of water.

Conclusion: What I have learned from this lesson today was that I learned that some of the different colors go up faster and some go slower, & that water and a water-based pen make the color go up if there is a cm involved...

Home Chemistry: Introduction

Aim: To learn the names of 10 household

chemicals and identify if they are a solid, liquid or a gas.

Equipment:

1. Soap/Detergent Dish

2. Lemon juice

3. Salt

4. Vinegar

5. Sugar

6. Milk

7. Onion

8. Lemonade

9. Bleach

10. Baking Soda

Task 1: Put the 10 chemicals

in a chart with the titles - Name, Chemical ingredient(s), Image, Solid/Liquid/Gas

Conclusion: This was a great experience
Trying to find all of the Chems/Ingredient(s), I have
Learned a lot so far & trying to learn more throughout my
Sessions in science.

Name	Chem/Ingredient (s),	Image	Liquid/Solid/Gas
Salt	Sodium chloride/ NaCl		Solid
Soup	sodium or potassium/ C₁₇H₃₅COONa		Solid
Milk	Calcium hydroxide/ Mg(OH)2		Liquid
Onion	sulfenic acid/ C3H6OS		Gas
Vinegar	Acetic acid/ CH3COOH		Liquid
Sugar	Fructose, galactose, and glucose/ C12H22O11		Solid
Lemon	Citric acid C6H8O7		Liquid
Bleach	Sodium hypochlorite/ NaCIO		Liquid
Baking soda	Sodium bicarbonate/ NaHCO3		Solid
Lemonade	citric acid/ C6H8O7		Liquid

I AM MALALA: Predictions

I AM MALALA is a Book and this is a book that is true so it is a nonfiction novel so I and some of my reading group we have to read the book about Malala and to this point, I think it is well and my task for this book this week is to: 

How do you think the book might end? Write down your predictions.

My prediction is that I think the young Malala grows up to change the world still being alive to the rights she stood up for and she became a worldwide leader, And he will be an international symbol of peaceful protest. 

   

Dmic Maths

For this Dmic Maths lesson, we started to work on a new equation these Dmic maths problems was all about the neighborhood & only a quarter of 92 will get mowed & then we have to add up  

The full equation is that: There are 92 houses on Rimutaka Avenue. 1/4 of them have asked me to mow their lawns once a week.

My mom has agreed for me to hire out our lawn mower for a rate of $2.50 per hour.

On average, it takes me half an hour to mow each lawn. 
    

A tank of petrol costs me $12 and lasts for 6 hours.

If I charge $15 per hour, How much profit will I make in one week?

This what my group & I did or am still trying to put it in better maths, words or numbers we were working out how much is 1/4 92 & we estimated that it was 23 because we halved it.

This is all we did and what we tried to do last week but this week the problem might be a little bit easier. 

Sentence Structures workshop

Walt: I have learned to make a complex and great sentence structures

Today we have made some sentence structure and we made them into complex sentences at the end and this is me and partners work we worked on this for a wee while but we made it hope this has helped you.

and here is something to solve try and find out what each word with a different color means?

*We played a game for three hours.

*We played a game for three pointless hours.

*This afternoon we played a game for three pointless hours.

*This afternoon we played a game of sleeping lions for three pointless hours.

*This afternoon we played an extreme game of sleeping lions inside the gym for three pointless hours.

*This afternoon we played an extreme game of sleeping lions inside the gym for three pointless hours while we were in the middle of a lockdown drill.
