Multiplying Decimals & Nutrient Cycle

Announcements:

• Please bring 2L pop bottles in this week!! (so far we have 10 of the 30 we need)
• October Break starts Friday - Classes resume October 15th

Math:

Students practiced quick facts (multiplication tables), reviewed adding and subtracting decimals and multiplying whole numbers using several techniques. They also estimated products of decimal multiplication questions. 

Question of the day: Is 7.2 x 5.85 closer to 40 or 400?

Science: 

We learned about nutrient cycles (specifically the Carbon cycle and Water cycle) by watching a Khan Academy video as well as several water cycle videos.

Students answered questions on Plickers and drew their understanding of the water cycle.

Highlights:

• Students learned that energy decreases up trophic layers and only about 10% of energy is passed on to the next layer. 
• They also learned that matter changes form, but is never created or destroyed. 
• They reviewed the process of photosynthesis where the sun's energy, water, and carbon dioxide are used by plants to produce sugar and oxygen.

Question of the day: What is a highlight for you from today's class?
