My brother made a "sneaker beeper" on time... it was more of a concept invention though\nbasically, it was a little bell you put in a shoe that was controlled by a remote... so if you lost your shoe, you could push the button the remote and go find it\nkind of like a telephone pager

I had to do this before, but I had to make mine out of candy. If you're allowed to do that, use candy. It's pretty easy. Just get some wire, twist them to the right shape, and use different kinds of candy on them. Once you have those up, then you'll need the wires that go across to connect them. I find that candies like twizzles and gummy worms work well. It shouldn't take that long to make. Good luck!

you could make confetti eggs and have the kids bust them over each others heads and everytime one gets busted, you ask how many are left and you can add eggs and ask them how many there are now. I think they'd have a lot of fun with it. Or you can use jelly beans as add and subtract with each individual tray. Tina

Little kids love play dough, especially the kind you make yourself that smells so good if you add a drop of peppermint.  The reicpe is just salt, flour, cream of tartar, peppermint, and food coloring - do an Internet search for it.  Making it with them is lots of fun.\n\nMake hand puppets from old socks and decorate a cardboard box to make a stage and do puppet shows.\n\nAll kinds of singing and dancing games, and musical instruments.  You can make your own musical instruments with them - rhythm sticks (wooden trowels, whatever works), shakers (empty containers with something inside and securely taped closed), drums (using ice cream containers), etc.  YOu can also buy simple ones quite cheaply at dollar stores.\n\nRead them lots of books and stories that have lots of rhyming words or language that repeats and they quickly learn to "chime in" with some of the words.  Check out the children's corner at your public library.  They often have a little kids story hour run by volunteers.\n\nLearn nursery rhymes and counting rhymes with them.\n\nDo little cooking projects with them - cookies, special snack foods.  Crackers with peanut butter and raisins, apple slices, grated carrot, etc. to make faces.  Bananas dipped in melted chocolate.  Homemade Mini pizzas they decorate themselves with their favorite toppings.\n\nBuilding blocks and magnetic letters and shapes give lots of ideas.\n\nAny arts and crafts activities, but they especially like finger painting.  You can also get recipes on line to make your own finger paint.  \n\nDo printmaking projects with them.  Cut potatoes in half and use them to do printing projects (cut a design in the cut side of the potato, paint the cut side or dip it in paint or on an inkpad, and press it over and over again onto a large sheet of paper to make a pattern).  You can use lots of objects to do this sort of printing/stamping project and it is much more fun for them than the stamps you buy.\n\nIf I think of more I'll edit this.  Hope it helps.

How old? Teach addition properly. Specially addition of same numbers repeatedly. It would make him understand multiplication. Give him sticks(match box, ear buds, tooth picks) and ask to give equally to friends, parents etc. Let the concept come in his own way. You are just to help not to stress. With thread/rubber band you may make 'tens' bundle with tying 10 sticks together. And show how 1 n 1 makes 11. Just some confusion is to be cleared. I think 1 week is enough. Be patient have patience.

How about a caterpillar? Check the crafts dept. at Wal-mart. Use stryo balls for the body, just glue five or six together in a line,  which you'll need to paint of course, add pipe cleaners for legs, just use wire cutters to cut them in thirds and just stick them in and bend them down, then use the stick-on googley eyes that they sell, and add a colored piece of paper cut for the mouth, and two toothpicks painted black and stuck in his head for antenna. Easy, and uses 5 materials

My son just did one for 4th grade.  He used Optical Illusions and their perception among age groups.  It turned out really cool.  We copied optical illusions from library books and pasted them up.  Then he made a stop-motion animation move on his computer, and explained how he did it.  He also made flip-books. It was cool.

1.  If you want an interesting project, try http://www.halfbakery.com/category/Computer Be aware that many of the suggestions there are either impractical, difficult, or not software-related.\n\n2.  Make a game.\n\n3.  If you want to make something new that people will use, ask if anyone has any ideas in the alt.comp.freeware newsgroup (unless you plan to charge) or look through the archives for requests for programs which were unfulfilled.

Now that's a wide open question.\n\nI'd build a robot and do some programming.  Robots are great for mechanicals.  Of course I'm an experienced (ahem older) engineer who just wants an excuse to but a bunch of lego mindstorms and program them too.  Yes lego has a website mindstorms.lego.com  (put that on your christmas wish list)\n\nBreaking things is fun and goes with material strengths classes.  Freeze it - break it - heat it break it. etc.  make friend with a professor in the lab so you can play there
