DNA EXTRACTION

Aim: To extract DNA from a banana
Materials: 1/2 peeled ripe banana                    1/2 cup hot water                   1 tsp salt                   1/2 tsp liquid dishwashing soap                    resealable zip-top bag                    very cold rubbing alcohol                     coffee filter                    narrow glass                    wooden stirrer

1. Mush the banana in the resealable bag for about a minute until all the lumps are gone and it almost looks like pudding.
2. Fill a cup with the hot water and salt.
3. Pour the saltwater mix into the bag. Close the bag and very gently squeeze and move the saltwater and banana mush together. Do this for 30 to 45 seconds.
4. Add the dishwashing soap into the bag and gently mix the contents. Try to avoid making too much foam.
5. Place the coffee filter in a clear glass cup, securing the top of the filter around the lip of the cup.
6. Pour the mix into the filter and let it sit until all of the liquid drips down into the cup.
7. Remove and discard the used coffee filter.
8. Tilt the glass and slowly add cold alcohol down the side of the cup. You want the alcohol to form a layer on top of the banana mix, staying separated, so be careful not to pour it too fast. Make a layer of alcohol that is 2.5-5cm (1-2in) thick.
9. After the alcohol layer is set up, wait for eight minutes. You may see some bubbles and cloudy material moving around in the alcohol. This is the DNA pieces clumping together.
10. Use the wooden stirrer to start poking the cloudy stuff in the alcohol layer. Spin the stirrer it in place to start gathering the cloudy stuff. When you are done, take a closer look at the stuff on the stirrer. You are looking at DNA!

Creative writing.

Reflection.

In the first week we learnt about haiku's and how to format them properly using seasonal writing themes for inspiration.

Once we finished that segment i practised writing in sensory language here is my example " I jumped out the car the hot concrete slams against my feet with every step, I view from a far the cool blue water by the wharf. I walk towards the platform the scent of sea water hits my nose alongside a gush of wind moving through my hair. I reach the platform jumping right in as i drop in the chilling water i hear the splash and the taste of salt hits my mouth."


As of late we are using metaphors and similes learning definitions and how to use them

Intro

I am a Hornby high student and for Digital Tech we were tasked to use the tool CANVA  to create an info graphic on ergonomics, i found canva easy and simple to use.

Reflection

The array of templates are perfect for any poster/info graphic giving you all the tools you need to make it look amazing. The image libary that they have is decent but the premium ones are alot better. Using images for the project was simple enough just crop and place the image you like and that suits your topic. Options to add your on images as well can give a good way to brand and watermark your poster getting your name out there
