Digital Technology Recap

Digital Technology Recap

For the last couple of weeks in digital technology we have been working on a lot of different projects like for the first project we had to use a infographic and do something about ergonomics. For my infographic I did it about posture and how it can effect you dont have good posture. The second project we had to play this game called interland were you learn about how to be safe on the internet. And also what thing you can share and what thing you keep to your self. And the last project that we did was about cyber smart and all of the different sections of it witch we had to write about. Some of the subjects were Smart Learners, Smart Footprint and a couple more.

The first two lessons in digital tech we have been learning about ergonomics. Below is a template of information about posture and how you can keep good posture and how you get bad posture. Hope that you enjoy it.

Ergonomics

Interland is an adventure-packed online game that puts the key lessons of digital citizenship and safety into hands-on practice. Play your way to be inter net awesome.

Today we have had to make a info graphic about all of the different types of being cyber smart below is a doc showing you everything that I have done.
Piktochart  

Also here is the site that I used to get all the information for this piktochart Link

Some things that I have really taken away from the last 7 weeks is that you have to be really careful when you are on social media or anything on the inter net because there are some dangerous people out there. I also learnt that I should start reading the terms and condition on things because if you dont you could be agreeing for someone to take money from your account every month. I also learnt about posture when I was making something about how you should sit. I have also learnt how to use a whole lot of different sites like Piktochart and Venngage.

Please feel free to leave a comment if you have any other questions about this. Overall I think that this is a really great topic. If you got the chance would you do it?

Science Sugar Crystals

Yesterday in science we had to get into groups of three and we had to make some sugar crystals. The sugar crystals were made out of sugar and water.

Method: 1. Pour approximately 50 mL of water into a 250 mL beaker.

              2. Pour 250g of sugar into a beaker.

              3. Light the Bunsen Burner with the beaker on top of the Tripod.

              4. Once the water starts to boil turn off the Bunsen Burner and pour a little bit of sugar into                        the beaker and start mixing with a stirring rod.

              5. Once the first lot of sugar has dissolved then put a little bit more sugar in and keep doing it                      until all of the sugar is dissolved and you have no more. 

              6. Pour the syrup into cups for each person and than put a popsicle stick inside of the cup and                    then sit it some where that it can set. 

Equipment: 2x 250 mL beakers, A pencil or stick, A stirring rod, Bunsen Burner, Heat Mat, Tripod and a gauze mat.

I learnt that if you have to much water and not enough sugar than it will stay as a liquid and if you have to much sugar and not enough water than ti will be a really thick mixture and it wont set. I also learnt that if you put to much sugar in at once than it will take forever to dissolve and it might not work how it is meant to. And also that making crystals can separate a solid from liquid. A highly concentrated solution was needed (Saturated Solution) to be able to grow crystals.

It has now been five days since we made the sugar syrup and put it into the cups. For the first few day it was still a liquid with little tiny crystals floating around but in the last two day it really started to form around the stick and the cup. Here is what it looks like when it is finished.

Feel free to ask any questions about this experiment.

  

Science Experiment

In science this week we did a experiment with purple crystals (Potassium Permanganate) because in science we have been working on dilution and concentration. For this experiment we had 6 test tubes and we had to put different amounts of water into each test tube. We then had to put one small purple crystal (Potassium Permanganate) into the test tube with the most water. We then had to use a pipette to take some of the purple water and put it into the next test tube. We then had to do the same thing and every time that we took some and out it in the next it kept getting lighter and lighter to the point where the last one was so clear that you could barely see any purple.

Method: 1. Place the six test tubes in a test rack. Label the rack with numbers 1-6
              2. Using the measuring cylinder fill the test tube 1 with 10mL of water. Fill the remaining test                    tubes with 5mL of water.
              3. Using your tweezers add a single crystal of potassium permanganate to test tube one.
              4. Gently shake the test tube until the crystal has dissolved. 
              5. Using the transfer pipette carefully remove exactly 5mL from test tube one and poor it into                      test tube two.
              6. Rinse the transfer pipette thoroughly to ensure that no purple solution remains.
              7. Gently shake the test tube two and repeat the transfer process transferring exactly 5mL of                        solution from the test tube two to test tube three.
              8. Rinse the pipette again and repeat the transfer process for test tubes four, five and six.

Dilution: A dilute solution contains a small amount of solute. At home if you were making a cup of week coffee in scientific terms you would be making a dilute cup of coffee.

Concentrated: A concentrated solution contains a large amount of solute at home if you were to make a strong coffee in scientific terms you would be making a concentrated cup of coffee

Thank you for reading my blog post about this experiment. If you have any more questions about the experiment then feel free to ask.
