How Things Work -Oscillating Water Column

In science we made a 3-D model of a Oscillating water column, a power generator that uses wave power.

Below is the 3-D model and two pictures with colour and more details.

How things work model 3-D

  1. What problem is your technology trying to solve?

The oscillating water column was created to make a good renewable energy source that won’t do any harm to nature and doesn’t use up our resources.

  1. Form and Function: What are its main parts and what do the parts do? How does it use or generate electricity? How do electrons move through it?

The structure consists of a big chamber, the walls of the chamber have an opening under water. The wave energy travels underwater into the chamber pushing the air in it up. The air goes through a turbine spinning it. When the water recedes, the air is sucked back in spinning the turbine once again. The turbine then creates electricity.

  1. What are the social implications? (How does it affect people?) Consider less developed countries and locations with different climates or geography.

The oscillating water column makes a lot of noise and can disturb people living nearby. This generator has to be on the shore, so it cannot be constructed inland. It also cannot be constructed somewhere protected from the waves.

  1. What are the environmental implications? (How does it affect the natural world?)

This form of energy is safe for wildlife. The only problem is that it makes a lot of noise that can disrupt wildlife, this problem would probably affect only species that live on ground. There are no moving parts in the water, so no animals will get injured by it. The structure itself acts like an artificial reef and can act like a home for certain animals.

  1. Given the strengths and weakness of your technology, is it a satisfactory solution to the problem it is trying to solve?

It is a good solution, it can supply towns further away from the shore, connecting the station through wires further away, but not too far. It also greatly benefits islands which are too far out to be connected to land. It causes no harm to wildlife and it won’t disturb you unless it is next door. It also doesn’t pollute, and it uses wave power, which is created by wind, which is created by the sun, so it will never run out.

Core Compentencies

Core Competent Canadians

1. What did you know about the Core Competencies before this activity? What did you learn?

I knew that that the Core Competencies are things that you work on in different projects. I learnt that certain peoples personalities  attribute them to one or more of the Core Competencies over the other

2. How can your knowledge of the Core Competencies help you in your school life? Personal life?

Knowledge of the Core Competencies can help you know what you’re good at and you need to improve. They can also tell you what different projects help you improve.

PE9 Substance Abuse Role Play

This is our PE9 role play to help you resist when your friends ask you to do things you shouldn’t

1. What are the influences involved in your role play?

This role play was meant to help you deal with people asking you to do bad things like drugs or alcohol. The influence is meant to be that it is bad and you should always refuse

2. Script

3. Explain how your conflict/issue was resolved. What skills were used to resolve this conflict/issue?

We used the refuse, delay and negotiation skills. Refuse is to come up with and excuse why you can’t and to say just no. Delay is to say you can do later like in a week. Negotiation is to offer something else to do that doesn’t involve anything bad.

4. How would these skills make the person in the play more resilient?

These skills will help you go against people that want you to do bad things, some of these skills will also help you not offend anyone and often make the situation better for everyone. This helps you avoid bad situations and will greatly help you.

A Fresh Look at the Periodic Table

Define and discover

We restated our task as: Reorganize the periodic table in a different way that will still show the same patterns.

Some of the questions we asked to help us achieve our goal are:

What are the patterns in the periodic table?

What are other ways the periodic table has been arranged?

What is the bottom part of the periodic table?


What information does the periodic table tell you?

Metals, atomic number, atomic mass, reactivity, families

How could you arrange it differently based on its chemical and physical properties?

You can arrange it by reactivity

What different shapes could be used?

Circle, like a character, rainbow, pyramid

How can you use colour?

Families, state of matter



Our periodic table was made so that it will be easier to read. There is no longer a big gap in the middle which can make it  a bit hard to read and the rare metals are now included in the table itself so it doesn’t skip over them. All of the elements are placed in order by atomic number and in columns depending on the number of shells. The two columns the most at the right where split in two because they took up too much space. A line connects them to show that they have the same amount shells. The families are represented by different colours and are at the same part of each column all the time, all noble gases are at the bottom end of their column, all alkali metals are at the top, alkali earth metals are just below them, halogens are in between the noble gases and metal dividing line, Transition metals are at the other end of the metal dividing line and the rare metals are only in the two columns at the right and in the middle of them.  The table is split in two to show metals and non-metals, hydrogen is in the middle as it has properties of both.


One thing that could’ve helped us would of been time, we didn’t have much time, so we had to go with our first best idea. We also had little time to develop a plan and ways to improve our project. One thing is that a few of the elements are sitting alone on the side, so they might be hard to notice. If we had more time we could’ve organized the table in ways to show more patterns.
