Here is the planning document for my goals.
For my expedition, I am doing it on elephants that are getting killed for ivory. I am doing this because I love elephants and if we don’t do anything about this, then elephants will soon be extinct. For my expedition my passion is photography. If I want to include photography I will either take photos of the shops in hong kong selling ivory or elephants in Africa. I think that I am going to do this for my exhibition ass well
For my science inquiry, I am working with Pippa and Nisha. For our experiment we are doing baking, we are finding out how much of an impact sugar is on cupcakes for this experiment we are using four different types of sugar, white sugar, brown sugar, powdered sugar and caster sugar. We are using the same experiment for each batch of cupcake mix.
Our hypothesis is, the powdered sugar will be crumbly and light. The brown sugar will be crunchie and more cooked. The white sugar will be a fluffy cupcake and the caster sugar will be a fine cupcake. caster sugar is very similar to the white sugar so there is a possibility that they will taste the same.
We are doing this experiment at school, me, Pippa and Nisha are all equally splitting the recipe so we can bring them to school.when the experiment is done we will reflect on what our hypothesis was.
- Caster sugar
- Self-raising flour
- Baking powder
- White sugar
- Brown sugar
- Powdered sugar
This week we did a science experiment called the egg suck, the egg suck was a really fun experiment and we learnt about the pressure of heat. For the science experiment, we had to fill out a sheet that looks like this
We had to fill out the question. Hypothesis, experiment( steps and observation), result, conclusion and further observations and new questions.
WHAT WAS THE EGG SUCK?
The egg suck was an experiment about if heat could fit an egg throw a beaker, this experiment actually had two experiments one was seeing if hot water could slip an egg throw a beaker and the second experiment was seeing if fire could get an egg to slip throw a beaker.
What I saw was when we poured the hot water we then put the egg on top of the beaker, when we were watching it, it started to slip throw the beaker after a while we got bored and pulled of the beaker and poured more hot water. I think if we didn’t fiddle with the egg and we left it, it would’ve slipped in. for the fire egg suck, we tried different things the first time we used paper and lit it on fire which didn’t work because it didn’t stay on fire so we tried that a couple times then since it wasn’t working we used a match. The match did work but since the beaker was very small the egg broke when it was going throw the beaker.
- Get a beaker
- Peel an egg
- Put water in a kettle
- Pour the water in the beaker
- Put the egg on top
- Watch what happens
- DO NOT LIFT THE EGG UP AND PUT MORE WATER
- Repeat but with fire
- Get a beaker
- Peel an egg
- Get a match
- Put it on fire
- Throw the match in the beaker
- Put the egg on top
Over three days we did 3 science rotations. The three science rotations that we did last week were baking, cooking and paper mache. The science rotations were lessons on the states of matter. For baking, the state of matter was, what is the difference if you put butter that is solid or if the butter is a liquid. For cooking we turned a liquid into a solid, the questions were does ice make a liquid to a solid. For paper mache, we made a liquid/flour + water a solid.
On the first day of the science rotations I did baking, for baking we baked cookies. We made two sets of cookies one with solid butter and one with liquid butter. My hypothesis was that the set with solid butter would become hard and crunchy and the set with soft butter would become soft and would rise. My hypothesis was wrong instead the solid butter cookies were very soft and the liquid butter cookies were crunchy.
- Vanilla extract
- Chocolate chips
For cooking we made something that was a liquid and then became a solid, we made ice cream. My hypothesis was that when we were mixing the liquid in the ice it would have become ice cream and taken much longer than 20 minutes. I also thought that I would be runny. My hypothesis was wrong, we shook the bag of ice cream inside the bag for 20 minutes and the ice cream became ice cream. Instead of the ice cream being runny it was soft and good, I think it tasted exactly like ice cream from a store.
- Vanilla extract
Paper mache was a really fun experience and we also learned a lot. In paper mache we learned about how flour and water become gluten, flour + water is what we use in paper mache to stick the paper together. My hypothesis was that I think that the flour and water will stick the paper together. My hypothesis was right the next day when we checked our paper mache they all looked good, I peeled off the tin foil and bowl under the paper mache and the paper mache did not collapse. There was only one thing that did not go right since we used flour and water instead of glue it tarted to mold because if you think about it if you leave gluten overnight it will start to mould.
- Get a bowl
- Get tinfoil
- Rap the tinfoil around the bowl
- Mix water and flour together
- Rip up paper
- Spray something so the paper won’t stick to the tin foil
- Put the piece of paper in the cup of flour and water
- Take two fingers and scrape off extra
- Make sure your bowl is upside down and then lay the paper on the tin foil
- Repeat until the bowl has a couple of layers
- Drie overnight
- In the morning take of the tin foil and bowl
These couple of weeks we have been doing different types of math but for this blog, I will talk about patterns. These patterns were about thinking outside the box.
This is the first pattern we did, I found this a bit hard and I struggled a little but in the end, I got the answer. The formula I did was you plus two from your previous number and that to your other previous number. If I made one mistake in that I would’ve messed up everything, so there was an easy way which was ( n + 1) 2. For this problem, I also found out a different pattern which was the number times itself is the answer for the previous case.
This pattern we worked with our math buddies, me and my math buddies did find out a way for this pattern but we didn’t find out a pattern which was 8 symbols. The challenge for the pattern was to find the formula and find a formula with 8 symbols
We made another pattern but I can’t find photos of it. We recently were doing graphs and seeing how to make a graph for a pattern.
