THE FEET CAN MEASURE THE HEIGHT

The bones of the feet can tell a lot about a person. What do feet reveal about a person's height? Forensic anthropologists team up with law enforcers to help solve crimes.

Bones of the feet can reveal an interesting fact about an individual. Let's combine math with forensics to see how.

Aim:  To use forensic science techniques to measure the height of a criminal.

Material:

1. foot 
2. measuring sticks

Steps:

1. get a ruler  
2.  to measure your height and length of your foot
3. write them down
4. Divide the length of each person's foot by his/her height. then multiply it by 100.

Findings:

Name	Foot  (cm)	Height (cm)
Me	22.5	153
David	24	148

Divide the length of each person's foot by his/her height. then multiply it by 100.

14.7058823529

My height is 153 cm and my foot is 22 and a half cm long. David's hight is 148 cm and his foot length is 
24 cm long. The way we measured our hight was to stack 2 rulers on top of each other. 
It is kind of surprising David has a bigger foot than me even though he's shorter.

Poems

Questions about emotions
what is mental health
when I am angry happy stressed
how do I deal with my emotions
who is the best person to talk to when
I am at home why
I am at school why

Math week 1

for math, we did lots of crosswords here's one I made with answers and clues

there was DIMIC maths which I wasn't apart of but I still solved anyway the question was Some octopuses, fish and a few mermaids are in a rock pool. Altogether there are 38 arms, 24 eyes and 8 tails in the pool.

How many mermaids are there?

all of the creatures have 2 eyes so you divide 24 by 2 = 12 assuming there are roughly the same amount of creatures we'll say there are 3 outputs 38 - 24 = 14 3 mermaids  14 - 6 = 8 8 legs left probably for the octopus 4 octopus + 3 mermaids mermaid have tails so 8 - 3 = 5 so there are              4 octopus  3 mermaids and 5 fish.

Drama

In drama, we made food pyramids the top is what you should eat the least of and the bottom is what you need the most of.

we went into a doughnut and told each other about our holidays

we also did chorus like freeze frames. This is when you freeze and do an action about healthy eating.

White Powder

Hurumanu - What is that white powder?

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.

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.  vinegar

6.  iodine

7. water

Steps

1.get powders split them into thirds 

2. add the iodine to 1/3  of all the powders

3. watch

4. add water to another third of all the powder

5. watch

6. add vinegar to another third of all the powder

Findings:

the mystery powder is baking soda

	Sugar	Salt	Baking Soda	Cornflour
Appearance	white	white	white	white
Texture	large	large	small	small
Smell	sweet	sea salt	lemony	none
Iodine	absorbs	absorbs	hardens	sits then hardens
Water	melts	sits	melts	absorbs
Vinegar	melts	absorbs	bubbles	sits

Write a paragraph about your findings.

The mystery powder was baking soda the main reason we were able to tell was that the baking soda with the vinegar made bubbles which were unique to the baking soda that reason the baking soda reacted that way was because together they create carbon dioxide.

100 words

here is a 100-word challenge about but it is the wrong colour.

"Can I have some green paper?"

"Ok, here you go".

"I ask for green not red".

"This is green".

"No, it’s red".

"It’s green".

"But it’s the wrong colour".

"Are you colour blind?".

"I don’t think so".

"You might be let’s take an online test".

"What number do you see?"

"5".

"What about now?"

"Red".

"Now?"

"8".

"Now?"

"Green".

"It says you're colour blind and that red is green and green is red for you".

"Oh".

"Can I have some red paper instead then?"

"Ok, here you go".

"And when he was done it looked terrible to everyone but him".

skittles

Skittles

Aim: To separate colours from skittles by using the chromatography.

Definition: Chromatography is a method of separating out materials from a mixture.

Eg. blood, ink, drugs,

Materials;

1. Yellow skittle. 

2. Red skittle. 

3. Orange skittle. 

4. Purple skittle. 

5. Green skittle. 

6. Petrie dish.

7. Water.

Process:

 Step 1: Get stuff you need.

 Step 2: Put skittles in Petrie dish.

 Step 3: Spread the skittles across the Petrie dish going to each edge of it with them remember to spread out equally.

 Step 4: Pour water into dish.

 Step 5: Watch.

 Step 6: Eat.

Conclusion: What have I learnt from this experiment?

This was a fun experiment and so cool to watch but the skittles were hard and sticky after we pulled them out of the water the reason the skittles looked liked they melted is that they have a food coating that comes of in water.
