Skyward Sword Heart Pieces
The Legend of Zelda: Skyward Sword features 24 heart pieces scattered across the land and sky, offering 6 Heart Containers to Link's total health.
Heart Piece #01
Location: Faron Woods
Earliest Available: Kikwi hunting
As you pass through Faron Woods, you'll come to a spot where there's a natural land bridge that makes a sort of "m" shape, with the middle of the "m" being a ramp. Climb up and take it to the far left (towards the tree) and you'll see a platform extending from the Great Tree containing a Piece of Heart. Use the tightrope to get across, balancing with the Wiimote.
Heart Piece #02
Location: Lumpy Pumpkin
Earliest Available: Before entering the Faron region for the first time
The owner of the Lumpy Pumpkin is very proud (and protective) of his fancy chandelier (that has a Piece of Heart on top of it). Upstairs you can see signs warning customers not to bonk anything. Purposefully roll repeatedly into the railing or wall nearby (upstairs that is) to make it crash down, and then snag the Piece of Heart. Pumm, the owner, is very upset with you and wants you to work off the debt (which leads to another Piece of Heart later).

After you have collected 10 Gratitude Crystals, bring them over to Batreaux and he will reward you with a Piece of Heart.

After breaking the chandelier in the Lumpy Pumpkin, you'll have to make it up to the owner. There are three things you need to do. The first of which requires an Empty Bottle. You will have to take a bottle of Hot Pumpkin Soup over to Eagus, the trainer at the Sparring Hall in Skyloft. Next, you will have to carry a stack of pumpkins to the storage area on the Pumpkin Landing without dropping any of them. Lastly, at night time you'll have to play the Goddess's Harp to an audience at the Lumpy Pumpkin, strumming based on the movements of the audience. After all three of these are done, you will be rewarded with the Piece of Heart.
Heart Piece #11

He will talk about the "ancient texts," and refer to one of several different riddles he found in the texts. The riddles are hints to draw something on the Goddess Wall. Draw the item referred to in the riddle, and if you draw the correct shape on the wall, Gorko will reward you with a Piece of Heart.
