Food Poisoning - HEC

Food Poisoning

What is bacteria? 

Bacteria is a unicellular microorganism which has cell walls but lacks organelles and an organized nucleus including some which can cause disease. The name of the bacteria that is common in causing food poisoning is called Campylobacter Jejuni. 

What do bacteria need to survive?

Like all things bacteria need food, water and a proper environment to survive and grow. By controlling nutrients, temperature, air, acidity and salt you can eliminate, reduce or control the rate that bacteria grow. 

3 examples on how we avoid bacteria from spreading.

• Placing foods in the right places with the right temperature and the correct foods they belong with. 
• Always making sure that your hands are clean, your fingernails, your hair, your uniform and the supplies that you are using are clean. 
• Making sure the food is not expired. 

What does the term cross contamination mean and what is its effect on you? 

Cross-contamination is a process by which bacteria is unintentionally transferred from one substance to another with harmful effect.

Scones - HEC

Scones 

Yesterday in Home Economics we made scones. Here is the process, how the team worked, the outcome, how they tastes and the texture and next steps. 

I got the dry ingredients for my group and combined the butter and dry ingredients together, I found the butter part a bit difficult because people were telling me I was doing it wrong. Here's a quick explanation of the process. 

Firstly we had to get all of our ingredients and then sift the flour, baking powder and salt into the bowl, secondly we cut the butter into cubes and then rubbed the butter into the bowl. Then we added the grated cheese and milk, then knead the dough on the table. Next we cut the dough into 8 squares and placed them on to the tray with a little bit of milk brushed on the top of each one. 

My team didn't do to well, we got distracted a lot and would argue over who was doing what. But in the end we got the scones finished and they didn't taste too bad. I would definitely like my team to work better next time or move groups. 

The taste and texture wasn't too bad but I personally think they could've been cooked a little longer because the texture tasted a bit raw but still enjoyable. The top of the scone was golden and nice but the inside was a bit gooey. 

Next time I think my group or whoever i'm working with everyone in the group should do something to help instead of one person doing most of it. 

Here is a outcome photo of the scones. 

 

Solubility Experiment - Science

Solubility Experiment

Aim: To see if salt or baking soda dissolves more in water.

Hypothesis: I don't have any theories but I think the baking soda will dissolve faster but it will turn to paste but that is it changing from it's original form so it had dissolved. 

Equipment: A 250mL breaker, 100mL measuring cylinder, salt, baking soda, a stirring rod, a teaspoon and a ruler.

Method: 

1: Fill the breaker with 100mL of tap water.

2: Add a level teaspoon of baking soda. A level teaspoon is obtained by running your ruler across the edge of the teaspoon.

3: Stir the solution until all of the substance has dissolved. 

4: Repeat steps 2 and 3 until no more baking soda will dissolve into the solution.

5: Record how many teaspoons of baking soda were added.

6: Repeat the experiment again with salt. 

Results: 

Solute	Number of teaspoons that dissolved in 100 mL of water.
Baking Soda	3
Salt	7

Discussion: Salt took more spoonfuls to stop dissolving. The baking soda took longer because it's attraction to water was less than salt and water.

Conclusion: The experiment did end up being successful. My hypothesis was incorrect but I was right about the baking soda dissolving faster.
