Need to make a worm house on how worms react to light and darkness.please help?

Fireflies produce light via a chemical reaction consisting of Luciferin (a substrate) combined with Luciferase (an enzyme), ATP (adenosine triphosphate) and oxygen. When these components are added, light is produced. \nThere are several theories on how fireflies control the "on" and "off" of their photic organs. However, the exact mechanism(s) has yet to be worked out. The "Oxygen Control Theory" is based on the firefly turning on and off its light by controlling the oxygen supply to the photic organ for use in the chemical reaction. The "Neural Activation Theory" hypothesizes that fireflies have neural control of structures called "tracheal end cells" which, upon stimulation, may release a messenger molecule in the photic organ which initiates the activation of the chemical reaction. Regardless of how fireflies control the "on" and "off" of their bioluminescence, the production of light in the above manner is very efficient. I think fireflies, or "lightning bugs" are amazing...another little demonstration of God's wild imagination.

Okay here goes.First thing you need is great insect repellent to spray yourself completely to keep the nasty bugs away.Buy the strongest sun screen to protect your skin.Wear a hat to ward off sun/heat stroke.Buy 6 bottles of water and a cooler with ice to keep them cold.Make yourself some snack foods for lunch and for the munchies.I also brought hand wipes to clean the worm gunk and fish smell off my hands.Buy a cheap but good rod and real with a small tackle box filled with all the little goodies you may need.Remember above all if the fish is smaller than your hand throw the poor thing back into the water so it can grow some more.

These bacteria probably have the lux gene which codes for bioluminesence. A resonable mechanism that would cause this to arise is mutation. These lighted cells would probably have benefited some how from glowing in the dark. Some deep sea fishes have bacteria which code for this gene (Vibrio fischer) Which may have helped these fish find food in the dark waters. Thus those fishes without this gene would have died out because of natural selection. What you could do is put these fishes with the bacteria that glow in the dark in the same pool of dark water as the fishes without this gene. Then provide a limited food source so that not everyone could receive food and only the strongest would survive. If the fishes without this bacteria eventually died out but the others stayed alive, you have proven your hypothesis. If not, then failure willl be an obsticle to overcome.\n\nHope i was helpful

Since you need simple and portable, how about starting with something that uses light and prisms to create the spectrum? \nFrom there, you could go to show how rainbows are created ( where the light must be, what the sequence of the rainbow spectrum is) or compare how light colors mix compared to how m=paint colors mix.  I don't know if that is appropriate for the 10 th grade.  But working with light and prisms is always fun.\nmagnetism is always fun, too.

1)Sunlight\n2)Twilight\n3)Midnight\n\nno joke, this is true. See link below.

worms like to come to the surface when its wet , not because they are drowning, but because its moist and they find mates.  Earth worms are hermaphrodites, and they lines up with each other with lots of slime and fertiliz each other.Once they are done they go back down burrows and deposit egg sac.

Put it in a dark room. If the mold had chlorophyll it would die without sun light. Molds do not and would consume the entire orange.

That's a great question!\n\nMy first thought was No, but I googled and found a great piece on worm hearts (see link below).\n\nIt turns out they have something that does a similar job, but is not a heart like we mammals have. Follow the link below for all the details.

dark is merely an absence of light.  Dark does not radiate.\n\nYou can biuld a big box and stop light getting in, but the box would be ineffective for anyone outside of it.\n\nYou could always try making a black hole.

E-mail me if you want a detailed step-by-step explanation. Illustrations extra..... :)

Use the pastel or whatever the kindergarden kids use.  It is like mud but comes in different colours.  The model should be a representation of the cross-section of your cell.  Use strings and other things to show different structures of the cell.  Some diagrams are drawn in 3D, and that's what your model should look like.  I wish they made us do that in university.  It would be fun.
