Connections based learning

When we had our first FaceTime I honestly didn’t really know what to expect. I had never really heard of Huntington’s before and I didn’t really know  what was gonna happen. We soon realized we wanted to help Tim get off the couch. We tried a few things out but nothing was really working and we had a lot of the same ideas as the other groups. So we decided to think outside of the box, and came up with an idea to help him hold a cup. It took us a while to think of how it would work. But we soon came up with a design, and printed it off. We realized it was too small so we asked Mr Robinson to get the measurements of Tim’s hands to give us a better idea of what size it should be.

We connected with Nikola and Tim. We needed to know if Tim liked coffee/tea to see if was even worth making. We learnt he does so we could go along with our plan. We also had to ask Tim if we could get a rough measurement of his hands to give us a better idea of how big we needed to make it.

We ended up making a handle that we are able to glue onto a cup. We had to really think through how it was going to work. We ended up with a sort of semi circle with a flat edge that could be glued on. We ended up putting finger holes in. We actually had to print off 2 because our first one ended up being too small.

A few skills I have learned and developed would be working with other people especially ones I dont really know too well. It also learnt how to use new things on my computer. Before this I didn’t even know what teams was and now I feel pretty comfortable using it. Another one is TinkerCad and understanding how 3D printers work a bit more.

I think the skills I have learnt could also be used in other classes not just science because working with others is a life skill I feel like. Also just getting my work done because I know other people are relying on it.I feel like I didn’t exactly meet the goals I set for myself for two reasons. 1 being i thought I was making something for the couch and 2 being when I made them I didn’t completely understand what we were doing fully. I definitely met some of them and looking back at the experience I am happy with what I accomplished.

The collaboration went  pretty good, me and my partner both did our fair share, and i’m happy we got to do it in groups because it just gave us different points of view to look at stuff and someone to go to if you needed help. It also cut the work load in half kind of.

We did well on thinking of a unique idea no one else thought of that hopefully will make Tim’s life a little bit easier. I think that there is a coule things we could have done better. We should have used the class time we got a little bit better. Not that we fooled around all the time but I think we kind of left some final things to the last minute. We also should have asked more questions when we didn’t understand something because it would have made everything a lot easier on us.

I actually really enjoyed the connection based learning because it wasn’t boring, like sometimes taking notes is or something. We also got  to guid ourselves in a way, there wasn’t really a criteria to follow. It also made you feel like you are helping someone witch I hope something we made does help Tim and make his life a little bit easier. I really enjoyed it and I hope I get to do something like it again!

What is DNA?

DNA is a molecule it is a bunch of atoms stuck together. The molecules are called nucleotides. The nucleotides has 3 parts to it. DNa is a double helix, as you can see with our model. DNA carries genetic instructions for growth and development.

What DNA does

Our DNA carries our genetic instructions, it pretty much stores long term instructions.

How it copies itself

Our cells are constantly copying themselves. It’s called replication. It will copy itself over a trillion times over a life time.  The helicase unwinds the double helix of DNA. When the replication starts it is known as the replication fork.  Then the RNA primase adds stuff, and then DNA polymerase does the rest.

What I have learned about grade 9 polynomials

What is a polynomial?

A polynomial is a math expression or question that has numbers, letters and exponents. An example of a polynomial is 2x+6y-3.

Vocabulary

Degree: The degree is when you look at all the terms and you take the highest exponent and that’s the degree of your expression. For example: x2 − 4x + 7, the degree would be 2.

Constant: The constant is the whole number that doesn’t have a variable.

Coefficient: The coefficient is the number that goes before before the variable, for example: 5xy (the 5 would be the coefficient)

Leading coefficient : The leading coefficient is pretty much the same as a normal coefficient it just means it’s at the start of the “line”. For example:  4x2 − 9x + 5 4 would be the leading coefficient.

Binomial: Binomial is when your answer has two terms. For example: 3x+5

Trinomial: Trinomial is when your answer has three terms. For example: 3x2 − 6x + 7

Monomial: Monomial is when your answer has one terms. For example: 7x2

Add polynomials

To add polynomials you group the like terms. the like terms are when they have the same exponent and variable. So you can’t add together 4 and 5x, because they aren’t like terms. What i do is a circle or make a box around the different terms and that’s how I make sure I don’t forget any of them.

Subtract polynomials

When you subtract, you still group like terms. But you have to flip anything in your bracket, because two negatives equal a positive and the rest equal a negative.

Multiply polynomials (distributive) 

When you multiplying polynomials you use the distributive property and you  multiply each term of the first polynomial by each term after. Then add the answers together and combine like terms to simplify. You also use the same law for exponents, so when you multiply the numbers you add the exponents.

.

Dividing polynomials

For division you literally just divide them, but keeping in mind you have to subtract the exponents.

Make connections to previous units (exponents and rationals)

Exponents definitely connect to this unit because we see them, and the higher the exponent the more powerful it is. Rational numbers also because we see them all, fractions, whole numbers and decimals.
