The bottle garden is a close relative of the biosphere: a tiny garden growing inside abottle, a glass sphere, or a demijohn. The main difference is that soil is the maincomponent not water. The container can be kept sealed or opened like a terrarium. Ourswill be more for just plants whereas the terrarium may have animals. These gardens in abottle, can be cured and perfected as a system, they are also very decorative, in fact youcan treat them as a bonsai with not only a single tree, but whole landscapes. A carefullychosen stone becomes a rock, a small plot of moss represents a great prairie. A contorted,little plant is now a hundred year old tree. Maybe a marsh wetlands with peat moss,mushrooms and ferns is more to your liking. Maybe appropriate succulent plants with sandand rocks for a vast desert landscape. The choice is yours. There is no rigid rule aboutbeing either an open or a closed garden. It maybe useful to keep the lid on to retainwater. Or eventually, the plants grow up and need to hang down the outside.
If the container is always sealed, the challenge becomes quite demanding. In fact, it thenis necessary to obtain an equilibrium between plants and animals in order to keep aneffective cycle of substances and energy, but if this is difficult in a predominantlywater environment, it is even more difficult in a just moist environment. So, the gardenhas to contain a moist soil, plants, little animals like terrestrial isopods (i.e.: sowbug, pill bug), earthworms, etc. Plants have to be resistant to high moisture and have asmall size and limited growth. To avoid roots rotten, you can also try to refer tohydroponics and substitute the ground with small sized expanded clay or with gravel. Inthis case you will have more difficulties in hosting animal species, so it will have to beleft open. It is important you place your garden in a cool and well illuminated place, butaway from direct sunlight. Open or closed, a bottle garden is a fascinating thing, and theidea itself of a little and self-sufficient world is fascinating as well. There are peopleso fond of bottle gardens they work at them a long time, taking care of them using longand thin tools and to observe these environments till they imagine to be one of theirinhabitants.
Then choose among these main options:
1 - Opened bottle garden, containing moist ground, plants and possible little animals. Itis suited for people who love taking care of gardens and who have a flair for
the architecture of little wide spaces.
2 - Opened bottle garden, prepared in hydroponics and containing plants. It is suited forthose who tend to forget to water their plants.
3 - Sealed bottle garden, holding moist soil, plants, and some little animals. Thisexercise is suitable for people who are keen on biology and scientific research. They willhave to find appropriate plants and animals suitable for a sealed ecosystem and will haveto achieve the necessary conditions for a long survival. This research, bibliographic inpart and experimental, will keep students happily busy for long time.
The educational value of these little ecosystems is evident. They can be carried out evenin a school, where the teacher will be allowed to illustrate their characteristics topupils and encourage interesting discussions. In the web sites below, you will findimportant practical information in building your bottle gardens.

After a shower, the soil is soft and the animals which walked there, leave tracks. Bymeans of plaster, you can obtain the mould of these tracks and make an
interesting collection (figure 9). The experiment is very simple: it is a question ofbringing a little plaster in dry form, some water, a bowl to mix the plaster,
and a spoon to stir. But, to which animal belong the tracks you have picked up? From herestart the research of information. They exist books which give the picture of the tracksof many animals. Moreover, recognizing the animal which left the track is not sufficient:it is necessary to know something of its behavior, etc. From the simple collection oftracks you will be curious to know the animals of your land. Our article: "" provides you some indication on this topic. This experiment will openyour eyes so you can observe the territory around you when you walk in naturalenvironments with more attention. Plaster can be used also to obtain the mould of fruits,barks and other natural objects. From the cast you can also obtain the original shape.

The rate of photosynthesis varies with several factors, including the intensity of sunlight and the temperature of the plant. (Other factors include the amount of water and the concentration of carbon dioxide (CO2) in the air.) You can design an experiment to test some of these variables: for example, will photosynthesis happen faster or slower if you put the elodea in warm water? Collect data by measuring how much oxygen is produced in a given amount of time when the elodea is submerged in warm water vs. cold water. You can either mark the level of oxygen on the glass with a wax pencil, or you can use a graduated cylinder instead of a test tube and measure more precisely in millilitres. Try to keep the other variables constant—it’s best if you can run two jars simultaneously so you know they are getting the same intensity of sunlight. If you only have one jar, how else could you make sure the light intensity is constant? Could you use a light source other than the sun?

The Scientific American Book of Great Science Fair Projects
"From creating your own non-Newtonian fluids (slime, putty, and goop!) to teaching a sow bug how to run through a maze, you'll be astounded at the number of incredible things you can do with Scientific American Great Science Fair Projects. Based on the long-standing and well-respected "Amateur Scientist" column in Scientific American, each experiment can be done with ordinary materials found around the house or that are easily available at low cost."
