Do you sink or float? 335581831 https://padlet.com/335581831/224vd0eyh0b5/wish/266440417 Relevant parts: 0:10-1:00, 1:30-1:55, 2:20-3:40. Feel free to watch the whole thing but only those parts are relevant to the topic 
In this video, Mark Rober was interested in how far he would sink if he jumped into a pool of 25 million Orbeez balls (superabsorbent polymer). He developed a hypothesis, designed and performed an experiment, and analyzed his observations and results. As a “firm believer in the scientific method,” he demonstrated strong scientific investigation skills and clearly explained why his hypothesis was wrong. He performed his experiment in a pool with Orbeez balls filled with water, relating to the theme of water. This item is significant because it accurately represents the scientific investigation skills necessary for each lab and is an essential part of the grade 10 science course. 

Demonstrate scientific investigation skills in four areas: initiating and planning, performing and recording, analysing and interpreting and communicating.

Reduced nitrogen removal could lead to nitrogen build up and climate change. This is because Earth’s climate is dynamic and is the result of interacting systems and processes. Overall, wetlands contain water, are a body of water, and connect to the theme. Environmental scientists conduct scientific studies, prepare reports, and develop management plans to study the environment and make sure it is not in danger. They provide scientific knowledge and advice to decision-makers so that the environment is protected when development occurs. Often, environmental scientists are found in the lab, the office, or in the field. The researchers are environmental scientists who have contributed to their field of study and the magazine, Water Canada, has many writers that are environmental scientists.

Through the lenses, you can see that the objects (the house and tree) are smaller. These prescription goggles are for correcting near-sightedness or myopia. The lenses are diverging lenses and make the light rays diverge before they reach the eye, focussing the object. The characteristics and properties of light can be manipulated with lenses to correct vision, even when swimming. This picture is significant because understanding the properties and characteristics of light, mirrors, and lenses is a crucial part of the grade 10 science course.

The periscope allows you to see objects that are above your line of sight like my face. This periscope was made with 2 mirrors at a 45 degree angle to each other; since the angle of incidence must equal the angle of reflection, this allows the light rays to leave the periscope parallel but lower than the object. Periscopes are often used in submarines to see above the water while the submarine is submerged. This application allows society to benefit from its use in water. In the grade 10 science course, we learned about how society has benefited from the development of optical devices and technologies, a periscope being one of them.

Despite this benefit, there are many ethical and social implications because the fish could be harmed. If released into the wild, the fish could destroy the marine ecosystem and the effect on human health has not been evaluated enough. It is very important to understand that advances in technology can have social and ethical implications. Since fish live in water, this is related to the theme. The fish were modified by genetic engineers who use a variety of molecular tools and technologies to rearrange fragments of DNA. The overall goal is to enhance organisms so that they are better able to thrive in certain environments.

Uric acid specifically, a byproduct of urine, will create cyanogen chloride when combined with chlorine. Another gas called nitrogen trichloramine can be produced which is linked to chronic health problems in swimmers. The products of the reactants can be predicted because chemicals react with each other in predictable ways. This connection is extremely important as predicting the reactions is a central part of the chemistry unit. Since the reactions occur in pools filled with water, this item is related to the theme.

He has become the go-to-surgeon for removing heart tumours and was able to diagnose a patient while several other doctors couldn’t. People call him a fixer of leaky valves and blown arteries, a transplant specialist and remover of heart tumours. The human body is made of specialized cells that can become mutated and turn into cancer cells. It is important to understand that plants and animals, including humans, are made of specialized cells, tissues, and organs that are organized into systems that work together. Heart surgeons are trained to perform surgery on the heart, lungs, esophagus, blood vessels and other organs in the thoracic cavity. The heart pumps blood and there is plasma in the blood which is 92% water, thus connecting to the theme of water.

These molecules are similar to methane molecules (CH4), but three of the hydrogen atoms are replaced with halogen (group 17) atoms—fluorine, chlorine, bromine, or iodine. Massive levels of lead were also in the water since oxidizing agents in water such as dissolved oxygen can react with exposed lead pipes causing soluble Pb2+ ions to enter the supply. To solve the problem, phosphate ions (PO43–) are added to the water supply. This creates a protective layer on the inside of the pipe. These negative polyatomic ions help to create lead(II) phosphate (Pb3(PO4)2), an insoluble, mineral-like crust on the inside of the pipes. Chemical reactions caused the problem and are also being used to resolve the problem; thus, chemical reactions may have a negative impact on the environment, but they can also be used to address environmental challenges. This item concerns the Flint water supply and is directly related to the theme.

The Ocumetic Bionic Lens would allow patients to have perfect vision and never get cataracts since their natural lenses would be replaced. This is a significant contribution to the field of optometry and could change the lives of many people. Optometrists examine the eyes and other parts of the visual system. They also diagnose and treat visual problems and manage diseases, injuries, and other disorders of the eyes. They prescribe eyeglasses or contact lenses as needed. Optometrists such as Dr. Garth Webb regularly manipulate the properties of light with mirrors and lenses to fix the eyesight of their patients. The procedure includes having a saline solution with the lens flushed into the eye with a syringe, where it would unravel itself within 10 seconds. The solution contains water, which connects to the theme.

This video opens our eyes to the “global bleaching event” that is occurring. Combined with El Nino, ocean temperatures stayed high, allowing the coral to continue bleaching. It is our responsibility to assess their impact on climate change and to identify effective courses of action to reduce this impact. The video accurately describes this and points out that the coral has a chance at becoming unbleached if we allow the ocean temperatures to decrease for a long enough period of time. The coral exists in the ocean which is filled with water, relating to the theme. This item is extremely important because it displays one of the many effects of climate change that could be reversed if action is taken to reduce the effects of climate change.

Increased temperatures cause ice sheets to melt and sea levels to rise, flooding coastal regions. This also makes the weather more extreme, making growing crops more difficult. Water supplies become diminished and new agricultural problems arise. People’s physical health can be affected due to the increase in smog that can lead to asthma, heart disease, and lung cancer. It is important to understand that climate change affects living things and natural systems in a variety of ways to realize the impacts of seemingly insignificant actions. This big idea was covered in the grade 10 science course in great detail as well as in the video. Sea levels are rising and seas are bodies of water, which relates to the theme.

Natural causes include varied solar output, volcanic activity, and Earth’s orbit. Human factors include the burning of fossil fuels and the conversion of land for forestry and agriculture. This extremely educational site gives insight into the devastating effects of human caused climate change that could warm the planet to levels that have never been experienced in the history of human civilization. It is important to understand that there are natural changes to climate but humans are speeding up the process at rates never seen before. Climate change is due to the increased greenhouse gases, one of them being water vapour, relating this item to the theme.
