Wave energy

Benefits:

It’s environment friendly. power from waves creates no harmful byproducts such as gas, waste, and pollution. Wave energy of tidal waves can be used as a source of energy. There are a few installations of that type is as source of power that comes from the endless march of the waves as they roll into the shore then back out again. The best thing about wave energy is that it will never run out. Current gathering methods range from installed power plant with hydro turbines to seafaring vessels equipped with massive structures that are laid into the sea to gather the wave energy.

Some words that could describe the paragraph on top are: Renewable, Environment Friendly, variety of Ways To Harness.

Challenges:

Why wave power has lagged far behind as energy source?

  • But a host of challenges, including the difficulty of designing a device to capture the energy of waves, have stymied efforts to generate electricity from the sea.

Wind and solar power have taken off in the past decade or two, as costs have come down rapidly and threats from climate change have made clear the need to transition away from fossil fuelsoperating in the ocean is far more difficult than on land; building offshore wind installations, for example, tends to be significantly more expensive than constructing wind farms onshore.

Issues:

Some researchers have long contended that power from ocean waves could make a major contribution as a renewable energy source. Several federal, state and local authorities would have overlapping jurisdiction over a WEC project.

My Questions:

How are waves form?

  • Waves are most commonly caused by wind. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.

What are waves?

  • A wave can be described as a disturbance that travels through a medium, transporting energy from one location (its source) to another location without transporting matter.
How big are waves?
  • Wind waves in the ocean are 60–150 m (200–490 ft)
Recommendations for Justin Trudeau
Wave energy is important because The energy from waves can be taken directly into electricity-producing machinery and used to power generators and power plants nearby. Wave energy is environment friendly meaning no harmful byproducts such as gas, waste, and pollution.  Wave energy are form from winder the ocean. In conclusion I think that wave energy is important and that everyone needs it.

 

Periodic Table COL Assignment

Renchie

Define: Our task for every group is to make a periodic table in our own way whatever we like

Discover: How many squares do we need in a periodic table? When we were figuring out how many squares we needed, we counted two sides of the scares and times it together, “9×14-8=118”

Dream: The periodic table tells us it’s density, It’s name, atomic number, and symbol. We arrange it by it’s density like lightest to heaviest. We used squares instead of rectangles in the periodic table. Were using the colour blue with 3 different shades of it because we use the light blue for lightest and dark blue for heaviest.

Design: We wanted to colour it 3 different shades of blue for the density, its ignorer by density, we made the shape as a square and put it all in row’s creating a bigger square.

Deliver: Our periodic table is in order by it’s density. In our periodic we made a giant square with little squares in it in row’s, it’s in order by density, we coloured darker every time the density is heavier.

Debrief: Maybe something we could’ve done better is to be more organise and make steps for our periodic table incase we do mistakes, we messed up a few times but
