kitchen table hypotheses: The Root of the Problem

In terms of environmental impact "sponge technique" is, by far, the less dangerous for both etchants (and the most economic with only 10mL of etchant used). You only need to rinse your sponge once finished, a tablespoon of etchant is not harmful (I've asked local authorities).

A lot of organisms emit light. Of course you know fireflies, but there are also otherluminescent organisms such as some fishes, mushrooms, bacteria, dinoflagellates, andshellfishes. The culture of luminescent bacteria is not difficult. What you have to do isto get a strain of luminescent and harmless bacteria and raise it in a suitable culturemedium. A bacterium widely cultured and used also for lessons in schools is the Photobacteriumphosphoreum, now renamed: Vibrio phosphoreum.
Search for information about the mechanism of the bioluminescence. You can findinformation for this culture and general information on the Internet at sites listedlater. There is a lot of information on bioluminescence on the Internet. There are evenamateur sites devoted to this topic. You can buy the Vibrio phosphoreum at commercially,such as the ATCC (American Type Culture Collection) .You can find other firms of this type on the Internet, using the keywords: culturecollection. Also try the links for the protists experiment. These companies also supplythe culture media and in their sites you can often read their composition.
: In these experiments, need thehelp of a biologist to avoid culturing dangerous microorganisms. Even with help, keep thecultures only for a short time, wash your hands, wash and disinfect all tools which havebeen in contact with the cultures.

Are the insects which fly around lamps at night attracted by light or heat? To find out,use a clothing iron and an electric lamp. The electric lamp produces light with a littleheat, the iron produces only heat. Put both on a table. Keep them at least a meter (abouta yard) apart and with the emitting surfaces turned away from you. Note the differentbehavior of insects. Mask the lamp with plastic sheets of different colors and verify ifbugs are more attracted to a particular color. This is also a method to capture nighttimeinsects, particularly moths, so you can observe them with a lens or a stereoscopicmicroscope.

The beauty of butterflies makes their culture particularly charming. Do not believe you will immediately have these beautiful insects, in fact for most of the time you will have to raise caterpillars and preserve pupae. Only at the end will you have butterflies. To culture these pretty insects, you first have to read texts about lepidoptera and practice in the field. In this way you will learn how to find butterfly eggs, to raise caterpillars and to keep pupae, waiting for the butterfly to emerge. Usually, butterflies prefer one or a few kinds of plants called hostplants. Caterpillars feed only on these plants and it is only on these that the adult female lays her eggs. So, in order to find the eggs of a given species of butterfly it is necessary to know which are its hostplants and when they lay eggs.
You should breed caterpillars in well ventilated cages. They have to be closed with mosquito net to avoid predators (figure 14). In fact, many bugs lay their eggs in the body of caterpillars. You have to feed your caterpillars with fresh leafy branches of the host plant. To do this you can pot these plants and insert them in the cage, or you can insert the cage over a branch without cutting it from the plant. If this is not possible, cover a branch of the plant with a cloth bag including the caterpillars. Cure the pupae according the suggestions in the books. When butterflies emerge from their cocoon, free them where you have collected the eggs. If you want to keep some adults to admire them, put them in cages like the one of the figure 14 and nourish them with mixtures of water and honey. Often, the caterpillars you find in nature are victim of bugs which lay their eggs on the caterpillar. In this case, there are little dark spots on the caterpillar skin. You can raise these caterpillars to study their parasites.

The Comprehension Hypothesis & Animal Language ..

Making an aquarium or a terrarium is not a complicated thing. Learning to build them isvery useful for those who are fond of breeding animals, observing them, taking picturesand movies. You can use an aquarium to breed fish, amphibians, protists, algae, artemia,shrimps, etc. You can use a terrarium to breed many species of animals, but avoid raisingspecies which suffer in captivity. Aquaria and terrariums can be used also to take picturesof animals temporarily taken from their environment.
In their simpler form, acquaria and terrariums are simple glass boxes enclosed on 5 sidesand which can be provided with a lid. This simple container is suitable to breedamphibians and as a terrarium. Aquaria for fish require a compartment for a filter, a pumpfor water circulation, another pump for air, a thermostat, lighting, etc. We'll deal ofthe simplest aquaria.
How you can build an aquarium? In first you have to make a drawing. The bottom glass hasto be surrounded by the other four walls and it has to be the thickest. The thickness ofthe plates has to be proportioned to the size of the aquarium. Avoid building too wide,and more importantly, too high an aquarium. The pressure of the water increases and couldunglue the plates. After having drawn the acquarium you have to cut the glass plates bymeans of a glasscutter. To do this keep the glasscutter vertical and push down with forcewhile you move it along a ruler. This operation require practice, so use some scrap piecesuntil you have the necessary manual ability. It is important you use a sharp glasscutter,kept in oil to avoid rust. Before gluing the slabs, you have to round off the edges withsandpaper in order to remove their sharp edges. With some acetone, clean the slabs wherethe silicone rubber will be deposited. As the acetone is toxic, work outdoor or in a wellventilate piece. Use high quality transparent silicone. To keep the internal walls free ofexcessive glue, on the slabs and near the gluing positions, place stripes of sticking tape(figure 6). When the silicone is cured, remove these stripes and the excess glue.
: handling and cutting glass is a dangerousoperation which has to be made only by adult people wearing gloves and a heavy apron. Away to elegantly solve this problem is to order plates. A hardware or building supplystore can help. Never move aquaria and terrariums containing water or stones, move them onlywhen they are empty. Do not place aquaria in positions where a water leak could damagesomething below them, for example over electrical devices or sockets, and books. Onlyadults should handle glass-made aquaria or terrariums. Give children transparent plastictanks. Do not keep dangerous or rare organisms. Do not breed and most important, do notfree species which do not belong to your environment! Do not free sick animals or plants.
