Salt crystals and FINALS!!!!

Last week we put salt and water to see it form crystals. Yesterday we looked at our crystals and Mr. Olson gave my group extra credit for the good looking crystals. This week happens to be finals week and i have been studying really hard and then we get off for winter vacation!!! It already feels like friday but its only tuesday. this week happens to go so slow.

Mole week

This week we found out how much is a mole and it is a big number. Scientists used this number like we use a dozen. On block day we did worksheets to calculated grams to moles. Yesterday we played a timing game to find out how many tiny little hole punched paper would equal to a mole. We used a scale to measure the weight but we didn't have enough time to finish calculating it. We also watched a video of Mr. Olsen and another teacher, Curtis sing the mole song.

Attractive Molecules

This week during chemistry in our lab, we used a buret and had a stream of water flow. We charged a wand and put it near the water to see if the water is attracted to the wand. Some liquids was attracted to the wand and water is one of them.

Smell Lab

we smelled bottles and described what we smelled. There was fishy, minty, and sweet. and on that week we had only three days of school because we had thanksgiving holiday. I had a great long weekend!!!!
