Earthquake Animation

I was learning about the three main earthquakes in New Zealand. (Napier Earthquake - 1931, Christchurch Earthquake - 2011 and the Kaikoura Earthquake - 2016.) we had to file some facts on these earthquakes then create a timeline in our inquiry books about NZ's shallow earthquakes. After we had finished a that we got to do a create, I chose to do a animation over two types of posters, a comic strip and a rap.

I found it easy to choose what the moral of my animation would be, it just popped into my head as I was finishing my last slide. To see what the moral was view my animation below. The other thing I found easy was to finish my animation before the deadline. I finished it so quickly that I still had enough time to create a rap afterwards. 

I really enjoyed using all sorts of different media to create my animation, eg shapes, polyline and backgrounds. I also enjoyed putting something funny in at the beginning, to see what it is take a peek at my said animation. 

Next time I will maybe hint my moral sooner on. Or I will put a bit more effort into making the characters in my animation have appropriate facial expressions for that moment. The only other thing I could improve on is having more people in my animation. 

Lava Lamp Observations

In our second science lesson we were learning about density and polarity. We created an example lava lamp using the ingredients noted below, the main ones was water and oil. We had to discover which one was denser. 

We figured out that the water was denser because it stayed at the bottom of the lava lamp. Adding the aspirin caused the said pill to fizz and dissolve creating carbon dioxide (Co2) bubbles. The bubbles floated between the oil and the water letting off carbon dioxide whenever it got to the surface.

The ingredients we used to create the lava lamp was Oil, Water, Food coloring and aspirin tablets. At the end it look really interesting and almost hypnotic.

I enjoyed doing the experiment in my buddy group after the example by Mrs Bava and the other groups. In my group was Lucas S, Liam J and Me. I am the only girl in my group, not that it really matters.

         

Bath Bomb Observations

Our first science elective lesson was based on acids and acalines, we had to observe the chemical reactions between the citric acid and baking soda. We each created a bath bomb for mothers day, using the ingredients listed below we mixed them together then left them to set overnight.  

This is what we observed: When a bath bomb comes in contact with water, the baking soda and citric acid react to make carbon dioxide bubbles. This is an acid–base reaction, where baking soda (also called sodium bicarbonate) is a weak base and citric acid is a weak acid.    

This is the bath bomb recipe you will need: (dry) - 1 cup of baking soda 1/2 cup of citric acid 1/2 cup of epsom salt (wet) - 1 tsp of water 1 tsp of essential oil 3 tsp of olive oil / coconut oil / Almond oil 2-3 drops of food coloring Measure out and whisk together your dry ingredients in a large bowl. Next, in a small cup, mix together the wet ingredients. This is also where you’ll add the essential oils. The next step is very important. Add the wet ingredients to the dry ingredients. You’ll want to do this very slowly, adding little drops at a time while mixing. The citric acid is what causes the bath bombs to fizz when it comes into contact with water. Adding the wet ingredients slowly minimizes this affect. Then, firmly press the mixture into the mould. Let the bath bombs dry for at least 24 hours.

I enjoyed observing the chemical reaction between the different ingredients, (the acid and the alcaline) I also enjoyed mixing the ingredients together, it felt not quite sticky and not quite dry. It was a bit like kinetic sand if you've ever felt it.
