Investigation Assesment

Hello readers, today is our investigation assessment task for health.

In this health unit, we have been studying Death, Dying and the afterlife. We have learnt about different cultural traditions and their beliefs. Some of the things we learn about are: Processes of death in different cultures, this is where we looked at how different cultures dealt with death and how they would hold a wake. Different stages of grief, and cultural practices.

In this investigation assessment, I would like to go through ‘Different ways people deal with death and their beliefs’ I decided to choose this topic because there were so many different cultures who do things differently when a person dies, and their beliefs about it, I’m just genuinely interested. An interesting fact I found about my country, is that in the Sagada, North Luzon, Philippines they hang their coffins on the side of the cliff, the reason they do this is because they believe the higher the deceased is helps them become closer to Heaven and likely have their spirit taken there. An elderly once spoke about not wanting to be buried underground. Why? Because she believed that water would soon seep into the soil making it a faster process of the body rotting, they wanted a place where their corpse would be safe.

Another interesting fact I found about the Buddhist culture, they would cremate the body after the service. The reason they did this is because they believed that cremation was an important ceremony from releasing the soul from their physical form. Their spiritual leader, Gautama Buddhist was cremated after his death, so many others will likely follow this tradition.

Why is it important that you take care of all sides of your hauora when you experience change, loss, grief?

It’s important for me to properly take care of myself in order to help me move on from whatever has happened. You cannot just be fixated on it and grieve about it all the time. It will be the only thing holding you down, stopping you from doing the things your body needs to do. Though it will take time to get back in place and in-touch with yourself, you’ll always get back to where you were.

 

 

 

Speeches – ESOL

Hello readers,

For today’s blog post I will be talking about my speech for ESOL, my speech was about my hobbies and their importance. The reason why I based my speech of my hobbies is because I wanted to give people an idea of what I enjoy doing and what I look forward to.

I had the confidence to speak in-front of my shared class, but then the outcome was I spoke too fast. And that was what went wrong. What I wanted to do was to get it done and dusted, though my speech wasn’t that long I still didn’t want an audience listening to me while being recorded. For anymore upcoming speeches I will do better by taking a deep breath and slowing down on my reading.

Light behavior

Aim:

Hello readers today I would like to experiment with how light energy behaves.

Research:

Here are two examples to give you an idea of what we are doing

Method:

Equipment

  •  Light box
  • Power Pack

Instructions:

  1. Get your equipment gathered.
  2. Plug in your power pack but make sure your plug switch is off.
  3. Plug the wires onto the black and red terminals.
  4. Turn on your power pack by adjusting it on 2V (volts).
  5. You can then now turn up the voltage.
  6. Take a single slit and put it at the end away from the lightbulb.
  7. Follow instructions on reflection and refraction videos.

Results:

(Photos)

Discussion:

Why does my face reflect upside down on the inner part of the spoon?

The inner part of your spoon will act as your concave mirror, the light rays then travel on the top of your spoon and reflect downwards.

What is concave and convex?

A convex is when the surface or outline is curved outwards, meanwhile a concave is the one that curves inwards.

What is reflection?

It is the return of light or sound waves bouncing off a surface. A mirror is the most common thing capable of this.

What is refraction?

Refraction is when the light bends. It is the change of direction of a wave passing from one medium to another. It is also possible for sound, water and other waves to do this. This ‘bending refraction’ makes it possible for us to have, magnifying glasses, lenses, prisms and rainbows. 

What is a medium?

It is a substance through which a wave can propagate; which means to move, or transmit in the form of a wave.

How do we get colors?

Let’s start off with light, light is made of wavelengths and each wave is a particular color.

A fact about color, is it really isn’t a part of our real world. It is just an illusion.

This will help their hauora by….

 

ESOL

This term’s ESOL objective is about speeches. Our speech we are working on is about our school holidays, we have to prepare a speech that is at least 1 -2 minutes long. The thing is we have to perform these speeches in front of the whole class, it’s a shared class between us year 9’s, 11’s, 12’s and 13’s which makes it a nerve-wracking performance.

I’ve done a public speech before in front of the whole crowd it was a Filipino event, things after that changed my confidence. I think I’ll do well in this speech, but there’s some things I still need to work on. Sometimes I get nervous and I don’t take the flow, my words get to me and I miss-pronounce my words.

Nuclear Energy

Aim:

For our next experiment for the term, I want to find out how to make grape plasma. It isn’t exactly a nuclear experiment, but it’ll do as we can’t do anything nuclear based in our science room.

Research:

Method:

Equipment

  • Microwave
  • Any  type of grapes
  • Glass cup
  • Safety glasses

Instructions:

  1. Get all your equipment gathered
  2. Be safe; use your safety glasses and definitely no metal in there, common sense but just a friendly reminder.
  3. Cut the grapes from top to bottom, but not all the way. Leave a thin strip of the grape skin. When you open it in half it shouldn’t be fully split, there should be a thin strip holding them.
  4. Put the grape in the microwave.
  5. Put the cup on top of the microwave.
  6. Put the microwave on high.
  7. It should go on for 1 minute.

Results:

Sadly I wasn’t able to do this experiment, I had another subject going on.

Discussion:

 

Chemical Flame Change

Aim:

My aim for the first experiment of the term is to investigate chemical energy.

Research:

Method:

Equipment

  • Safety Glasses
  • Heating Equipment
  • Different types of metal salts
  • Wire loop
  • Nitric Acid
  • Small Beaker

Instructions:

  1. Get equipment ready.
  2. Be safe.
  3. Set up the Bunsen burner.
  4. Make sure to clean your wire loop using the Nitric Acid.
  5. Dip the wire loop onto the salt of your choice.
  6. Put the salty wire into the blue flame of Bunsen burner.
  7. Observe what is happening to your fire.
  8. Repeat the instructions using different salts, but before you dip your wire loop into another salt, make sure you clean it using the Nitric Acid.

Results –

Types of chemicals used and their colors:

Copper II Chloride – Green

Strontium Chloride – Red

Copper II Sulfate – Orange (a more pigmented one)

Sodium Chloride – Yellow

Potassium Chloride – Lilac or pale violet

Discussion –

What causes the metal salt to perform color on flame?

Flame colors are created by the movements of the electrons in the metal ions. When the electrons relax to its ground state they give off energy which is perceived as light of a particular color.

How does chemical energy work and what is it?

Chemical energy, this is an energy which is stored in the bonds of chemical compounds. Chemical energy is released when a chemical reaction occurs.

 

 

 

 

 

Dilution Of The solution

Aim:

I would like to find out how to make a concentrated solution more diluted.

Research:

Method:

Equipment:

  • Test tubes
  • test tubes rack
  • Water
  • Dropper
  • Potassium Permanganate crystal
  • Safety glasses
  • 10 mililliter measuring cylinder

Instructions:

  1. Get your equipment ready.
  2. Fill the test tube with ten milliliters of water measured out from the measuring cylinder.
  3. Fill the rest of the test tubes with 9 milliliters of water from the measuring cylinder.
  4. Put one crystal of KMno4 into the first ten-milliliter test tube.
  5. Using the dropper. Extract 1 milliliter from the first test tube and add it to the second test tube with 9 milliliters.
  6. Clean the inside of your dropper.
  7. Repeat instructions number 5 and 6.
  8. Record your solutions.

Results:

(No picture)

Discussion:

How does dilution work?

Dilution, which you add more solvent in simply like water, decreases the concentration of the solute in the solution. To dilute a solution means to add more solvent without the addition of solute. Concentration is the removal of solvent and doing that increases concentration of the solute in the solution.

 

 

 

Investigating state changes

Aim:

Our aim for this science experiment was to melt ice which we oppose ‘Dry Ice’ This experiment was also a part of our Education Perfect learning as well, because we will start to focus our learning on what we have been learning about.

Research:

Method:

Equipment:

  • Beaker
  • Bunsen burner
  • Matches
  • Ice
  • Salt (optional)
  • Gause mat
  • Heat mat
  • Tripod
  • Thermometer
  • Retort Stand
  • Clamp
  • Timer or stopwatch
  • Safety glasses

Instructions:

  1. Get equipment ready and be safe.
  2. Set up the Bunsen burner, but do not light it.
  3. Fill half of your beaker with ice and add a 50mL of water.
  4. Set up the stand, clamp and thermometer.
  5. Make sure the thermometer is not touching the bottom of the beaker.
  6. Measure the temperature of the ice.
  7. Light the Bunsen burner and heat the ice with a blue flame.
  8. Start timing.
  9. Every 30 seconds, record the temperature of the ice/water.
Results:
Discussion:
What happened?
The ice that was put in the beaker turned into a liquid due to temperature changes. The state changed because we heated the ice and it had higher energy compared to the ice where it had lower energy.
Water can melt at the same temperature it freezes, but at room temperature it will slowly reach it’s liquid state.
The 3 states of matter and their transitions.
There are 3 states of matter, solid, liquid and gas.
When the water particles are frozen, they vibrate slowly and have many bonds meaning this is solid. But as you slowly heat the frozen particles up it would vibrate more and the bonds will move over each other, this is reaching their liquid state, but when you heat the liquid more, it turns into gas which means their bonds are broken and they can move freely.

Water Filtration

Aim:

For this term’s science, we will be doing chemistry. Our first experiment we will be starting this term is water filtration. We will be making water filters and drinking the “clean” water we’ve filtered the dirt out.

Research:

https://www.youtube.com/watch?v=60Big9Ut6Mc

https://www.youtube.com/watch?v=lrnt9QswVZ8

These two videos show 2 examples of ways you can make a water filter, I looked at the most simple ones I can find. And the equipment required that I can provide for myself.

Equipment:

  • Plastic Bottle
  • Handful of cotton
  • Gravel/Pebble
  • Rocks
  • Sand
  • Charcoal
  • Scissor
  • “Dirty Water”

Instruction:

  1. Cut your empty bottle in half.
  2. Place the top half of the bottle upside down onto the other half.
  3. Place a handful of cotton inside the bottle and push it down.
  4. Pour a handful of sand into the bottle, making it the second layer on top of the cotton.
  5. On the third layer put a handful of charcoal on top of the sand.
  6. Even the amount of gravel and pebbles just like the other equipment, making it the last layer.
  7. Pour the dirty water onto the filter, the water should come out clear at the tip of the bottle.

Results:

I do have a picture, however I’m not able to insert it through my post. I don’t know why and what’s causing my device to act like this.

Although the water filter paper was able to take out the big pieces of dirty sediments, it doesn’t fully clear out the water. It does clear out the water by 99% though.

Discussion:

What is the purpose of the rocks and pebbles? The purpose of them is to take out bigger sediments out of the water.

How do water filter papers work?

Filter papers have small pores, and this allows the small liquid molecules to pass through. This doesn’t allow the large solid particles to get in.

Why is it necessary we have clean water?

It is essential that humans drink clean water, because when we drink contaminated water and poor sanitation it leads to different types of diseases. Most of these diseases can cause immense pain and could possibly lead to death.

Is it safe to drink filtered water?

Yes it is safe, if you were to use a method like we did. Where it takes out the larger sediments and clears the water. It didn’t give me any sort of side effects. But if you didn’t know, the bacteria living in the water hasn’t fully broken down, and this bacteria called Giardia, can make you poop just water.

What is filtering? What are we separating?

Watering filtering is when we separate a solid from a liquid.
