Our blog ­­­­­­­­­­­­­­­­­­­­­In our experiment we tested to see which out of the 5 metals we chose (magnesium, copper, aluminum, iron, and zinc) will corrode the most in a time span of 20 minutes. We started the experiment off by weighing the metals and acid until we had exactly 50ml of hydrochloric and 5 grams of each metal. However, we then thought that 5 grams was too much, so we reduced the weight to 1 gram for each metal but on the other hand we kept the amount of acid at 50mls. If we were to redo this experiment then we would also reduce the amount of acid to 25mls since we…

Over the last three weeks we have been doing this AMAZING experiment where we explored the pH of the water affectin g plant growth. We planted some green beans and some grass and watered them with the same amount of water. The only difference was that we watered them with acid, alkali, and neutral water. The plants grown very well. Infact the beans have been ate by a bird!  During this experiment, our plants grown well and the results have shown that plants grow well in neutral water. Our hypothesis was supported by our results but the mind-boggling this was that the acid beans sprouted FASTER than the neutral beans! That was way out…

In this experiment, we only used two ingredients which are the coconut oil and lye to make the soap. It is a very easy way to make soap. Also, we used the food colouring to make our soap more colourful and beautiful. However, perhaps we added too much or it was not a good choice to add food colouring. Thus, when we use them to wash the dirty stain on the fabrics to compare with store-bought soaps, it caused a problem: the food colouring dyed the fabrics. We did our experiment to test if our handmade soap work by: comparing handmade soap with store-bought soap by timing the seconds that the soaps…

What is Our Experiment? Our experiment is measuring the rates at which different meats dissolve in Coca Cola. Coca Cola has a pH of around 2.3, which means it is acidic enough to dissolve meat. Our stomachs have a pH of 1.5 to 3.5. We wanted to see if different types of meat would dissolve at different speeds. What did we find out? We discovered that the fish dissolved the most, but we suspect some of our data may have been maladjusted because there was a problem with our data collection method. What were the highs of the experiment? The most fun parts of our experiment was working together and brainstorming ideas.…

The Reflection: General we done well at the experiment that a good brilliant positive thing in whole year. Kevin were proud of our self's its a nice to see in the academic.   i found difficult is that we change bread to much because some of our bread are bitten by  birds and a mouse , second thing is that i become impatient at the bread not growing moulds.   the challenge is that we have to suffer from the disgusting moulds  it smells horrible and the lesson i learned is  not to afraid of experiment failures. we suffer from two failure (change breads: bread bitten by animals) but patient tell us…
