A.    Introduction  

1. Transition/Review:  Review what we have learned about plants: what they need to grow, kinds of plants.
2. Motivation:  Have several terrariums to show children and stimulate their interest.
3. Statement of Main Problem: We will create our own ecosystem in a terranium.
4. Value of the lession:  Follow sequential directions, a very important skill, especially when you do science experiments

B.    Development

1. Use pocket chart to learn facts about terrariums
2. Have children echo-read the four facts on the chart.
3. Have children fill in the blanks on their application page using the facts on the chart
4. Review application page together.
5. Begin making terrariums.
6. Have materials boxed/
7. grouped for each group (soda bottle halves, pepples, charcoal).
8. Explain directions:
    
   •  First, place pebbles on bottom of once bottle.
   • Second, spinkle a little charcoal over the pebbles.
   • Next, put 5-6 spoonfuls of soil in bottle bottom.  **Remind them that they need to take turns and wait patiently for their turn.**
   • Aftter you have put soil in, make three holes in your soil.  (Plant the small plants and seeds in these holes.
   • Finally, using the water bottle, spray three sprays on the plants.
   • Then return to your seat and raise your terrarium.  Be sure you wash your hands!!!
   • When you have finished, write in your observation log about the experiment and draw a picture of your terrarium.
    

C.    Summary/Evaluation

   Review why the terrarium will live on its own and we will not have to water it.  Perfomance based evaluation will be used; we will observe the students as they create their terrarium.
