I guess this isn't exactly a teacher gift, but it's a cute school idea, and I just couldn't not post it. I saw this idea a few months ago here. I love apples and peanut butter, and I guess I need to add worms to that list too b/c the whole package is yum! I sliced an apple in half, cored out the seeds with a melon scoop, and created a little hole for a worm (you can do this with a fat straw (like the slurpee straw, but I just used a knife). I then added about 1 T. of Peanut Butter to the center.
I then popped the lid back on to the apple, and I ate it. If I wanted to save this for a few hours before eating/giving it away, but prevent the apple from turning, someone gave me the great tip that you can dip apples in sprite or 7-up to keep it from turning, but avoid the bitterness of the lemon/water bath.
