Science

Today I had science class. I learned about gravity and my science teacher took out two balls(one big one small) and asked which one will land first on the ground. Everyone said the bigger one will fall quicker but I said the balls will land together and I was right. I also learned about gas. My teacher bought two two liter sodas. He put mentos inside the soda and then the chemical reaction began. The bottle over flowed. It was carbon gas coming out. I also tried vinegar with baking soda. It did the same. I memorized the abbreviation of baking soda. It is NAHCO3. I love doing science.
