Are you seriously asking that?  Frogs jump the same way people jump. The muscles in their legs expand and contract. And yes frogs reproduce. Where do you think they come from???

"Some frogs have a 3rd eyelid (called a nictating membrane - like dogs) which may be drawn across the eye to protect it, but allowing some partial sight:"\n\nthere you go!

I'd suggest you look in the front of your textbook.  It will be along the lines of "The principles of biology are. . . ."  Usually when they ask open ended questions like these they don't want a thoughtful and insightful answer like the ones given above but rather, for you to parrot the aforementioned sentence back to them.

frog\n\nits a small green thing.I like it, because it so well represents a small green amphibian.

Toads and frogs are BOTH amphibians.  Frogs have more permeable skin so lose more water through their skin and need a wetter environment.  Toads have dryer, wartier skin and are generally darker in color. Frogs lay eggs in clusters on water, toads lay eggs in strings. Frogs jump farther and have longer legs, toads hop. Frogs have tiny teeth, toads do not have teeth.

sure why not! Did you ever hear of the frogs that change sex?

frogs need at least enough for them to soak in, and because of evaporating I would make sure it was about twice their height.  But more importantly then the amount of water is the fact you change it often to prevent illnesses.  Then your frog will be happy and so will you

look in a library book or a science book...

I suggest this:\n\nShow your friend a water drop,\nlets him imagine that this drop is made of smaller, smaller, smaller water drops,\ntake some peas (uncooked) as examples.\n\n(This would be water molecules)\n\nExplain, that water under room temperature is liquid,\nexplain him with the peas that this means that the water droplets\ncan move free around, they can bounce against each other \n\n(this would be molecules behaving on a certain kinetic energy level)\n\nbut when it gets cold than they start to stick to each other form something called a crystal.\n\n(This would be phase-transition between liquid and crystalline state and the work of the van der Waal'sche force. )\n\nYou can show that by gluing the peas together or use a toothpick to stick them together.\n\nWhy they are all to different: because they have so much different possibilities to stick together and form all this different snowflakes.\n\nAnd you can prove that you are right by showing him that a snowflake melts down into a water drop.\n\n(In fact they can only form certain three dimensional structures but he will learn later. If you develop this story over the years you end up in physics/chemistry and chaos theory.)\n\nHave fun ! There is nothing more interesting to see how a child starts to understand the world and you can be apart of it.\n\nThe real explanation you will find here:

go to the website for the Natural History Museum in Washington DC.  I took my kids there last year and they have skeletal structures for just about any animal you can think of.  Check it out.
