Number Visuals {Maths}

14/02/18

For this activity we as a class and group looked and different shapes which were up to 35,
we had to figure out what kind of pattern it was in, because some shapes looked alike just different amount of squares, triangles or circles in the shape.

We as a group had to come up with a conclusion of how the patterns on the paper were connected to each other.

Some groups concluded their findings that some patterns if you add up the number would equal the next pattern. for example the fifth pattern has 5 and the next pattern is ten which looks the same.

Human Rights

What I learned about human rights?

I have learned that not all of the human rights are known to many people around the world, not only are they unknown, they are also not used as of now many people around the world still suffer from Torture, Slavery and many more. So far in the subject, human rights, I still think that governments should put these rights further up in their priorities.

So many can live the life they wish for.

Extracting DNA from a banana

Aim: I want to investigate how to extract DNA from a banana.

Materials:
* 50 g of banana
* food blender
* a piece of clean muslin 20×20 cm
* distilled water
* 250 mL beaker
* dishwashing detergent
* measuring cylinder
* cold 95% ethanol ( kept in fridge)
* universal indicator solution.
* boiling tube with rubber bung
* hooked wire on a handle
* petri dish.

* cauliflower or strawberry can be used instead of banana.

Method:

(1) Place 50 g of banana and 100mL of distilled water in the food blender and switch on high for 20 seconds.

( breaks up food sample)

(2)
Pour the blended banana mixture through a piece of clean muslin into a beaker.

( they will remove annul lumps)

(3)
Measure out 15 mL of the blended banana mix and pour into a boiling tube. Add 6 drops of dish washing detergent, put a rubber, bung into the tube and shake for at least 5 minutes( mixture should become thick and gooey)

( shaking with detergent breaks open cells and release their contents)

(4)
Carefully add 15mL of cold alcohol to the tube of banana mixture. The alcohol forms a layer of top of the blended banana.

( this separates out the DNA)

(5)
To collect the DNA, dip a hooked wire into the mixture where the layers meet, then turn the wire to twist DNA onto the wire hook. Carefully remove the hook with the DNA and place on to a clean petri dish. Watch carefully as you lift the DNA from the mixture.

(6)
Add some universal indecator solution to your DNA.

Results

(1)
What does the DNA look like?

I thought it we wouldn't have a lot but the DNA looked white.

(2)
What is the pH of DNA (answer)
Is DNA acidic, basic or neutral?

Acidic

(3)
What is the full name of DNA?

Deoxyribonucleic Acid

One of the processes that scientist can carry out using DNA extracted from cells is DNA Fingerprint. What is DNA Fingerprint, and what is it used for?

Genetic fingerprint.

It is a technique that detects a lot mini satellites in genome.

Evaluation {PBL}

11/12/17

For PBL we had our ups and down but we finished just in time.

We didn't get much done but we worked well to get some action plans done.

We didn't do what we wanted but that is what we would work more on next time.

Science (bucket head)

1/12/17

Today we are doing the bucket head activity.

Aim: I want to find out if we need our senses and walk in a straight line.

Hypothesis:
I predict that if you don't have your senses( sight, smell, taste, hearing, touch) then you have a 50-50 percent chance that you will walk straight

Equipment:

* blindfold to stop you from seeing
* Cotton wool stop you from hearing.
* bucket for our head to stop the wind

Method:

I will try and walk in a straight line.

Use the cotton to stop me from smelling other smells.

Results:

I didn't do the activity but some students did.

Most of them started of straight but went a different way halfway.

Some talked to the person doing it so it ruined the activity.
