Bowerbird courtship behaviour

 What is courtship?

- courtship can be described as mate-selection rituals. Animal courtship may involve complicated dances or touching, vocalisations, visual display of beauty or fighting prowess, or via chemical production (pheromones, etc.). Courtship rituals are species specific. Even closely related species have different courtship behaviours. This ensures that energy is not wasted on interspecific mating. One of these example is the bowerbirds (ptilonorhynchidae). Their courtship behaviours  are renowned for their unique courtship. Males build a structure and decorate it with sticks and brightly coloured objects in an attempt to attract a mate. Mate-searching females commonly visit multiple bowers and many females end up selecting the same male. Underperforming males fail to attract mates and reproduce. The most elaborately decorated bower took more energy and resourcefulness on the part of that male bird, suggesting greater 'fitness' as a potential mate. This mate is more likely to collect quality food and nest resources and have an increase chance of reproductive success. 

Ethical approach

In this class, we were asked to make models about different approaches. We've been learning about 5 different approaches which are virtue, utilitarian, rights, fairness and common good approach.We chose fairness approach and model it with a playdoh. Fairness approach is 

The Fairness (or Justice) Approach states "Treat people the same unless there are morally relevant differences between them." 

• Fair and equitable distribution of good and harm, and/or the social benefits and and social costs, across people in society.

• Fairness requires consistency in the way people are treated. 

• The principle states: TO BE FAIR TO ALL (is ethical) - Social Justice = to be ethical the outcome needs to be fair, inclusive and non-discriminatory.

This is our hero called "Koro". Out hero "Koro" demonstrate a judge. A judge looks at the evidence and reasoning of both people present in the court fairly. The judge's job is to serve justice by rendering a fair impartial decision on the issue.

Ancestors Stone trend

 For these past few weeks, we've been learning about evolution. Trends in tool use is part of dispersal of hominins and how they were able to think and make more complex objects with the available resources around them.

We tried making the stones that previous hominins made as potatoes and carved them with a knife.

The stones that we tried to make were, Chopper (East Africa), Hand Axe (Libya), Hand Axe (France) and Solutrean blade (France).

Gummy Bear Experiment

 Hi, for today's Biology lesson, we are experimenting on gummy bears. We're learning about the process of osmosis and we have three different types of beaker with different types of solutions with a gummy bear in each beaker. One beaker consist of 3 spoons of sugar, one is 3 spoons of salt and last one is just water. Water level is 50mL. 

Hypothesis: I think that the gummy bear on sitting on the just water beaker will get bigger as the water molecules will enter the gummy bear and the sugar molecules in the gummy bear is hyper tonic to the water.

I think that if we place our gummy bear on salt water, gummy bear will get smaller as there are more salt molecules compared to the gummy bear which will cause the water to move out.

And I think gummy bear is isotonic to the sugar water beaker.

Here's a gummy bear😜😇😍😘😪😱🙊😑💞 I also had 3 gummy bears for me to eat

RESULT

We let the gummy bears sit on their beaker for a day and saw some changes. The gummy bear sitting on the water solution has increased its sized the largest out of all three. Gummy bear sitting on the sugar solution has also increased its size but water bear is still bigger. Looking at the salt solution, the gummy bear has decreased its size and it became tough when you touch it compared to its original size. The remaining two gummy bears became softer and water bear has almost lost its color.

The results have proven that my hypothesis was correct. The gummy bear was hypertonic to the water in terms of sugar. It was isotonic to the sugary water. And the salt water was hypertonic to the gummy bear solution as there are more amount of it compared to water. If there are less water, gummy bear is going to end up having a higher concentration of water, and in order to create an equilibrium the water in the gummy bear will leave as the solution of salt water is hyper tonic.

ESOL Trip Planning

In our esol class, the class suggested to go on a trip and the teacher told us to blog about places that we want to go to. 

1. Adrenalin forest -  it is an adventure park. The students will enjoy and have the chance to exercise their bodies. For educational purposes, we can talk about forest or trees or about people falling from high places. However, this place is a forest which means it is outdoors and the weather may not be good. 

2. Laser strike - students will also enjoy in this place because it is fun. First, we can learn about wars before or how the technology changes over time.  

3. Skydiving - very fun.

 The Final Kick Scene

Brainstorm:

- A character kneeled in front of an old guy and cries.

- An old man died

- A person pressed a button and and explosion happened.

- Earthquake came and buildings getting destroyed by strong winds.

- People suddenly waking up when they are about to fall the water or hit something. 

Technique:

Color - white, blue, grey, orange because of fire

Lighting - cold, melancholy, analogous, dim,  make audience feel tense

Sounds/music: slow violin playing, bombs going off, buildings cracking, after the bombs bomb tense music starts playing, shouting people because they can't hear each other, water splash

The sound suddenly stopped when the people falls of the water

Camera:

Shots - close-up, mid shot,

Movement -

slow motion and long shot - can be seen when there are cars falling. / people lying down on the elevator floor while bouncing.

mid shot - between the old man dying and the guy unlocking a box.

sudden close-up to a picture frame of a young man holding the toy that the came from the safe. It tells us that the toy is significant to the old guy and his son.  

Statement: In the "Final Kick" scene, slow motion is used when people are starting to fall and 

Example: The people are falling out of a car or elevator as they sleep. As they fall, they woke up from their dream and hits reality. S

Film Technique Practice - Lord of the Rings

 Brainstorm:

- Four hobbits are hiding under a tree from the Black Rider. They are afraid - see on their faces. 

Technique:

Color - pallete - green, black, grey, dark, natural/nature, dull

- feels cold and uninviting.

Lighting - natural, dim, cold - makes it feel cold and uninviting.

Sound/music - diegetic sounds - horses hooves approaching, bugs crawling, birds, movement of riders armour, sounds of his breathing - little sounds are magnified when we are afraid. 

Camera:

Shots - Focus - tilt shot - from the rider to the hiding hobbits, 

Movement - angle - close-ups - hobbit forces - scared, nervous

- bugs - crawling across the hobbits, shows how difficult it was to keep still and quiet.

- Three closeups on parts of the rider - the horses hooves pawing the ground, the horses muzzle with red eye and the riders feet hitting the ground. Builds suspense before we see the rider.

- Low angle - looking up at the rider, shows hobbits cowering below, makes the rider look bigger, intimidating and frightening. 

Statement: In the 'Black Rider' scene close-ups used to show the fear of the characters as they hide.

Example: The four hobbits are running from the Black Rider. They seek refuge in under the roots of an old tree as the rider approaches. Close-ups shows us the expression of fear on the hobbits faces.

X-audience - This makes the audience feel intimidated and anxious with the hobbits as the unseen enemy arrives.

X-director - The purpose of this is to build suspense before we see the rider. Like the characters, we are afraid even though we don't know what is coming.

X-link technique - Combined with the close-ups is the use of diegetic sounds including the horses hooves on the ground, the breathing of the rider and the clinking if his armour as he dismounted. These sounds add to the feeling of fear we have seen through the close-up shots.

Y-your real world connection - Interestingly, most viewers have felt the fear of being chased and found before. This allows them to connect with the emotions of the characters in this moment.
