Science World Assignment

By: Shirley Phan

Here’s My Group:

I went solo.

Water’s for Dinner?

About 10.5 bathtubs of water are used to grow a meal of chicken, rice, orange and milk.

*the energy drum was under construction therefore i was not able to use it*

Animal Weight

This is the animal weight of my “group”. I weigh as much as an aardvark.

LocomotionThis is a beaver which moves by swimming/crawling with it’s two front hand tucked together.

As I am demonstrating.

KEVA Bridge

The most challenging part about building a bridge was building the arch part.

Infrared Camera

How can you tell which parts of your body are warmest?You could tell which parts of the body are the warmest by the colour on the screen.

Rita has the hottest head.

Me and my Shadow

Things I noticed about my shadow are it lasted for no more than 8 seconds and it was not very bold.

Defying Gravity

Another illusion involving mirrors that we saw in Eureka! was the Anti- Gravity Mirror.

Squish!

What part of your body does this exhibit challenge?I think that this exhibit challenges your back and legs since those are the longest part of your body.

Stretch!

What part of your body does this exhibit challenge?

The exhibit challenges the hamstrings and calves muscles.

React!

In my “group”, the reaction time for turning off five lights was 3 seconds.

Face-Aging Software

This is me at age 65.

Halo

This exhibit demonstrates the waves of the lights and that lights can be mesmerizing.

Part B 1) Three thing that I learned/surprised me the most about the IMAX Human

Body Films is that the women’s largest cell in their body are their eggs, we create around 2 million cells per second and that the mother and the father’s DNA must meet in order for the baby to be created . These things surprised me since they’re not things you typically learn in science class. Even though the facts are about my body, i’m just amazed by the fact that our body can do so many things!

2) An ostrich have many differences and similarities to the human body system. Five differences between the ostrich and human body system is an ostrich has 3 stomachs while the human body has only one, an ostrich walks on two toes while humans walk on five toes, the ostrich has feathers to keep themselves warm while humans have skin and hair to keep us warm, an ostrich lays eggs while human give birth live and an ostrich can run as fast as 50 kilometers while human can run around 10 kilometers . Five similarities between the ostrich and human is both of them are omnivores, both of them rely on their legs to support them,they both can’t fly since their body weight is too heavy ,both have a similar network of arteries and they both have something to keep their body in balance, the ostrich has their wings and humans have their arms.

1) Ostriches, giraffes and goats have different shaped eyes compared to humans since their habitat is different from a human being. Ostriches have eyes that are bigger than their brains. They are almost 5cm in diameter. Ostriches have a small head on a long neck . This allows them to have a large view of their surroundings. For example, the ostrich can see if an animal is trying to sneak up on it. To help them see as much as they can ostriches have a very large eye. A giraffe also has a very long neck with eyes that are portional to their head. Their eyes have thick eyelashes since they live in dry areas. Giraffes has two eyelids, one to protect their eyes and one to clean their eyes. Giraffes also has very good vision. Their good vision helps them avoid surprise attack from predators. Goats have rectangular pupils. Although it looks very weird, these eyes are extraordinary. The human vision covers a visual panorama of 160-210 degrees, whereas the goat vision covers 320-340 degrees. This means goats have a vision of everything around them without having to move it’s head. Humans have color vision that is best described by the number three. Colors that we can see can be bright or dark of different hues and different vividness. There are very few other animals have similar color vision to human. There are some animals that can see more color variation than humans can. There are also a lot animals that cannot see colors like us .Instead, they see shades of gray and maybe some other type of of change in hue. Although some animals can see as well as us, they can see way better than us in the dark.
