This week will be the second week of the Vermicompost sequence. In this week, we are going to focus on one specific genre of worms that is commonly used in the Compost Wrom Bin - the red wigglers. This week's objectives are: 1. Observe the compost made by red wigglers(in the composting bin made by the students last week); 2. Opportunity to add the compost to a school garden; 3. Reinforce the concepts taught in the first lesson about recycling, composting and waste reduction.

In this sequence of lessons, we are going to introduce the students with the idea of Vermicompost. In the first week, we are going to focus on Garbbage-eating worms. The objectives of the lesson are: 1. Introduce the students to the concept of compost kitchen wastes in a worm bin; 2. Introduce the importance of worms in the eco-system; 3. observe worms and worm behavior via magnifiers; 4. Experiments on worm-preferred environment; 5. Build a classroom composting worm bin; 6. Experiments on worm-preferred foods and observe the process of composting.
In this week's lesson, we are going to explore the topic of ecology webs. The key this week is to emphasize how different organisms depend on each other in an eco-system. This week's lesson will have a brief review of the predator - prey lesson at the beginning and will dig deeper into the relationship between different organisms.
This week is the second lesson of the Arabidopsis sequence. In this week, the students will actually grow their own plant in the green house they made last week. The first activity of the week is to examine the results of the Germination experiment we conducted last week. Next, we will give out the seeds to the groups of students and let them grow their own plant in the greenhouse they built last week.
In this sequence of lessons, we are going to introduce the students to Arabidopsis. Arabidopsis is a genus of plants that we can easily grow with limited space. The sequence of lessons consists of two lessons. This week we will focus on two major objectives: 1. Test how plant variations influence germination in response to different environmental stimuli. 2. Build and test a greenhouse. The two objectives will build a solid starting point for next week's lesson.
In this quarter, we are going to start introducing the students to various concepts on Ecology. This week's lesson focuses on the topic of predators and preys. The two key take-away points are: 1. What is predator, what is prey; 2. The dynamic relationship between predators and preys. One of the many useful online demonstrations is: http://www.eduweb.com/portfolio/studyworks/predators8a.html.
In this lesson, we are going to explore another important ecological concept - a Watershed. To learn the basic idea of watershed, we are going to help the students build a model of a watershed. During the process, we are going to introduce the students to the circulation of fertilizers, pesticides and other chemicals enforced by rainfalls. The students will also learn about the shaping capabilities of the movement of water.
