How does this happen? Reminders: --Write HW in agenda --Voice level at 0 during Do Now --Tutorials this week: Monday lunch, Monday afterschool, Thurs. Lunch This week’s HW: Cycles Overview – Due FRIDAY

2 ESSENTIAL QUESTION: How does matter cycle and change through living systems? OBJECTIVES: -Observe cycles of matter -Discuss how and why matter cycles -Define Cycles and Biomass

3 Decaying Watermelon Timelapse
35 Days shortened to 1 minute. Turn and Talk: What decomposers are at work in this video? What might be the benefits to decay? Are there any negative consequences to decay?

4 What if? Turn and Talk Describe what it would be like if no organisms were ever broken down, if that they remained preserved at the surface of the Earth.

Forest Fire! The wood you were within is burnt and you have been released into the atmosphere. or Some nitrogen can get into the water in clouds and then fall as rain!

30 Surface Water How did you arrive? Where are you at?
Where are you going? You fall into a lake or stream so now you are part of surface water. or You are just the sort of nitrogen that plants need to live. You are now within a live plant! You are decomposed and become dissolved in surface water! Surface Water or What’s that in the water? You have dissolved into surface water! You travel through the rivers and streams to the ocean! Debrief Question(s): 2. If plants need nitrogen to grow, then how will adding extra nitrogen to the water affect the growth of aquatic (water) plants like algae? Aquatic plants will die Aquatic plants will grow rapidly Aquatic plants will not be able to preform photosynthesis. You dissolve and wash into the surface water! or The groundwater you are dissolved within travels and you become part of the surface water! You percolate deep underground in the groundwater!

31 Rain Water How did you arrive? Where are you at? Where are you going?
Some nitrogen can get into the water in clouds and then fall as rain! You fall into a lake or stream so now you are part of surface water. or You fall on the land and become part of the soil! Rain Water Debrief Question(s): 3. According to the map above, which parts of the United states from 1989 to 1991 had higher concentrations of nitrogen in the their rain. South West United States North East United States North West United States You percolate deep underground in the groundwater! or You rain into the ocean!

32 You percolate deep underground in the groundwater!
How did you arrive? Where are you at? Where are you going? You percolate deep underground in the groundwater! or or You dissolve and wash into the groundwater! The groundwater you are dissolved within travels and you become part of the surface water! Ground Water or or Debrief Question(s): 4. Aquifers are like underground likes that store water. Texas has many aquifers, which we draw from for our drinking water. Which major aquifer does Austin sit above? (see large map on back) The groundwater you are dissolved within travels and you become part of the ocean! Look out! Water is on the move! You have washed into the groundwater!
