Gummybear Experiment

Osmosis- osmosis is the movement of water molecules from an area of high concentration to an area of low concentration. These molecules move through a semi-permeable membrane. 

Semi-permeable- a substance that allows only some things to pass through. In osmosis, only water can pass through the semi-permeable membrane.

A solution with a high concentration of solutes is called Hypertonic when compared to a solution with a low concentration (Hypotonic). When two solutions with the same level of concentrations are compared, they're called Isotonic.

We did an experiment to see if the gummy bear has more concentration compared to the 3 solutions- salt water, sugar water, and normal water.

Hypothesis-

Gummybear in saltwater-  I think the gummy bear in the saltwater solutions neither shrivel nor will it become turgid.

Gummybear in sugar water- My hypothesis is that the gummy bear is hypertonic compared to the sugar water solution because the gummy bear has a more concentrated solute than the sugar water. 

Gummybear in water- My hypothesis is that the gummy bear in normal water is hypertonic as there is no solute in normal water.

Results-

Gummybear in saltwater- The gummy bear shriveled in saltwater. The gummy bear was hypotonic compared to saltwater because there was more solute than water. The water in the gummy bear exit to meet equilibrium. 

Gummybear in sugar water- The gummy bear in sugar water expanded. The gummy bear was hypertonic compared to the sugar water solution because there was more solute in the gummy bear than in the sugar water solution. The gummy bear absorbed the water in the sugar water solution to balance the amount of solute. 

Gummybear in water- The gummy bear in normal water expanded. The gummy bear was hypertonic compared to water because there was no solute in the water so the gummy bear absorbed the water to balance the amount of solute.

Pasion Projects

For the past few weeks in Wananga, we have been doing passion projects. I have been making bracelets out of loom bands.

I have learnt how to make different patterns with the loom bands. I have also learnt different colour combinations. I didn't have the proper tools for making loom bands so it was a little difficult. Maybe next time I could use proper tools to get better results. 

Boy- Getting dressed for the big school

Uniforms are very important for British Public schools. This is because it conveys a sense of discipline and reputation. In the book boy, Roald Dhal describes the type of uniform they used to wear. His uniform included a butterfly collar, braces, waistcoats, and tailcoats. 

Why does Christchurch value school uniforms?

Uniforms play a key role in promoting pride, self-confidence, and a feeling of belonging within the student body.

I think uniforms are important as it shows the reputation of the school. It also makes everyone feel equal no one seems too rich or too poor. 

The Best Pizza

Joe Beddia tells us how to make the best pizza step by step.

Step one-  The Dough

He makes his pizza dough from scratch. He uses organic bread flour, water, sea salt, fresh cake yeast, sugar and extra virgin olive oil. Let the dough come at room temperature and flour anything that touches the dough. For example your hands and the counter. 

Step two- Cheese

He uses two types of mozzarella cheese. He dots the stretched dough with half thumb sized mozzarella pieces then tops the rest with low moisture shredded mozzarella. It's all about the coverage for him.

step three- When to top

Some toppings are best cooked from the start and some are best topped after cooking.

 Things to cook with the pizza- thinly sliced asparagus, boiled (crumbled) potatoes, sauteed mushrooms, or fresh baby spinach.

things to top after cooking- chopped chives, paper-thin slices of cured meat, fresh basil leaves, or anchor fillets.

Step four- Sauce

The trick for his red sauce is good tomatoes and sauce. To make white sauce he uses heavy cream add stuff like herbs to it and whip it in the food processor until it's pretty thick.

Step five- pizza stone

The dough requires a hot surface to cook on. Otherwise, it will dry out. The pizza won't be crispy or and delicious. 

Step six- Treat it like pasta

Finish your pizza with aged cheese and olive oil. 

Step seven- Meat

Use really thin cured meat. They melt a little bit

Step eight- Pickled Chiles

Add fresh pickled chiles to finished pies.

The Doctor's Visit

Today in Wanaga, we read another chapter of the book 'Boy'. In this chapter, he talks about how medical services were back in the day. They did not use any anaesthesia to numb the area before operation. Today, medical services are more advanced than they used to be.

 

Pasion Project

 Week 1:

In Wananga, we are doing passion projects. For this, we have to choose something to do which interests us. Then, we have to come up with a question that will help us to do it. Once we have answered the question, we have to do a little presentation as proof of our project. I will be making loom bands and selling them. 

 

Week 2:

This week for passion projects, I have started making my loom bands. I found resources from teachers as shops don't sell loom bands anymore because they were a choking hazard. I have also started making posters to promote my Business. I will continue to make the loom bands over the holidays. I still need to sort out the prices for the loom bands. 

Boy- Roald Dahl

 Boy, an autobiographical book written by Roald Dhal, talks about his life in a boarding school. In the chapter we read, he talks about the Matron who was in charge of the dormitory floor. Everyone was scared of her as she could send you to the headmaster at any time to get caned. She didn't like little boys.  

Rules back then were very different to the rules today.
