Science is Number 1!

20141008-101406.jpgWe really like science because we are like real scientists. Right now in our science lab we are learning about landforms. We are learning about mountains, canyons, plateaus, dunes, valleys, meanders, plains, floodplains, beaches, and deltas. We have papers that say the landforms and gives the definition of it. I have never heard of some of these landforms.

Today in science lab we learned about acid rain and what it does. We needed to wear safety goggles because we were handling liquids. We needed safety goggles during our experiment because vinegar is an acid and it can burn your skin. We had to share them because we are a class of 34 students. We have filled a big cup with water and filled it up halfway. Next, we took syringes and extracted the water and put it into a smaller cup. We all took turns. We put 25 ML of water and then we put in 5 ML of vinegar in another cup. This was very fun to do.

What will happen when we mix the water and the vinegar? We thought it would bubble. It did but not a lot. We added a rock to the mixture and it smoke a little more. The rock dissolved a tiny bit.

We talked about acid rain. Did you know that it breaks down rocks that’s called erosion? It takes one day for the rocks to go through the process of erosion.

If you want to try this yourself, here is the recipe for doing this experiment:

1. This is the strong one: 20 ML of vinegar and 5 ML of water and add in a rock

2. This is the weak one: 5 ML of vinegar and 20 ML of water and add in a rock

Remember, if you try this at home you need to wear safety goggles.
