This week we returned from break to a 3 day week. I started the week by reviewing cells using a webquest. I then moved on to photosynthesis and respiration. I began class showing the student a gift I received for my birthday. The gift was an Eco-sphere. The concept of the Ecosphere was  developed in NASA’s jet propulsion laboratory. It is a completely closed off system that sustains  3  shrimp, algae and bacteria. It really got my students asking questions.
