Monday, August 30

Today in class, we started the day off by discussing the blog. He showed us the seating chart that also shows when our blog dates are, so we could remember which day we were going. Then Mr. H detailed how to log in, and how to format our posts. He proceeded to described to us how we also have to put tags in our posts, and how to put in pictures.

The next part of class today was the lecture. The lecture consisted of Mr. H telling us about Atoms, Molecules, Elements, and Compounds. He Explained how Matter consists of particles, and these particles can be individual atoms, or molecules (multiple atoms attached to each other). He also told us how atoms are elements, and that each one has it's own name ans symbol. The last part of the lecture was about how atoms can exist individually, combined with multiples of the same atom, or bonded to different types of atoms.

To finish off the day, We had a lab to do. This lab involved mixing calcium chloride, sodium bicarbonate, 5 mL of an aqueous solution, and phenol red indicator in different combinations. The groups started off by mixing all of the substances together. This produced a red liquid inside of the bag, and the bag started to inflate! This shows that the reaction was producing some sort of gas.

The next test involved mixing Calcium Chloride with the Sodium Bicarbonate. This produced no reaction for my group. Also, my group failed to complete the last part of the lab, and therefore we have no data for the last part.

Today was a very interesting day in our chemistry classroom. We learned much of the basics of chemistry, and we did a very cool lab in addition to that. I think we all had fun today.
