Procedure and Data (20 points)
1. Remove the label from a 2- or 3-liter plastic soft drink bottle and wash the bottle. Be sure to rinse it very well so that no soap residue remains. Let the bottle dry.

2. Use a marker to draw a line around the bottle, about one-third of the way up from the bottom.

3. Use scissors to cut along the line you drew on the bottle. To start the cut, poke a hole in the bottle at some point on the line.

4. Place about 2 inches of gravel or pebbles in the bottom of the bottle. This layer will be a place for excess water to collect. It will keep the soil from getting too wet. (Optional: If you want your terrarium to last longer, sprinkle some activated charcoal and moss on top of the gravel or pebbles.)

5. Fill the remaining space in the bottom of the bottle with moist potting soil or dirt. Gently press down on the soil with a gloved hand until the surface of the soil is about 1 inch below the rim.

6. Add plants to the terrarium.

a. If you are using seeds, use your pinkie finger to make 8 to 10 small depressions in the soil. They should be about 0.5 inches deep. Place 1 or 2 seeds in each hole and cover them with soil.

b. If you are using live plants, remove 2 or 3 small plants from their containers. Be sure to keep the root ball intact. Plant them in the soil.

7. Pour tap water onto the soil so that it is moist but not completely soaked. Just a little bit of water should pass through to the pebbles. You should use less than 1 cup of water.

8. Put the bottle back together by sliding the top part onto the bottom part. Keep the top on the outside. You may need to squeeze the rim of the bottom section so the top section will fit around it.

9. Place the cap on the terrarium if it is not on already. Your setup should look like this if you started with young plants:

10. Describe your terrarium, including what you put in it and where those materials came from. Attach a photo or draw a diagram of your terrarium. Add labels to identify the important parts. (8 points)

























11. Place your terrarium next to a window where it will receive plenty of natural sunlight. Do not place the terrarium outdoors. Observe the terrarium. If you planted seeds, wait until they sprout to begin recording what you see. If you start with live plants, you can begin recording your observations the next day. Make observations for four days in a row. Look at the terrarium first thing in the morning and at the same time each afternoon. Take note of where water can be observed. Look at how much water is in the pebbles and on the sides at the top of the terrarium. Record your data in the table below. (8 points)

Data Table for Observations in Bright Light

Morning: General observations
Morning: Observations of water
Afternoon: General observations
Afternoon: Observations of water

12. Move your terrarium away from the window so that it gets less sunlight. It should still receive some natural light. Continue your observations for two more days. Record your data in the table below. (4 points)

Data Table for Observations in Dim Light

Morning: General observations
Morning: Observations of water
Afternoon: General observations

13. If you want to continue to watch your plants grow, place your terrarium where you think they will grow best. If you are done with your terrarium, collect the materials inside and dispose of them as instructed by your teacher. Rinse and recycle the plastic bottle.

Analysis and Conclusions (30 points)
1. Explain how your terrarium modeled each of the following processes in the water cycle. (10 points)

Condensation:




Evaporation:




Precipitation:




Infiltration:




Transpiration:


2. Draw a diagram to show how your terrarium modeled the water cycle. Include labels for the five processes in question 1. Add arrows to show how water moves through the water cycle. (10 points)

















3. How did the force of gravity affect the movement of water in your terrarium? (2 points)










4. Compare your observations of the terrarium when it was in bright light and dim light. What can you conclude about how sunlight affected the water cycle in your terrarium? (4 points)
































5. What is one advantage of using a terrarium to model Earth's water cycle? Explain. (2 points)

















6. What is one way in which you could improve your terrarium in order to show more parts of the water cycle? (2 points)
