Early experiences with melodies moving upward and downward can be really fun for young children because you can introduce instruments and integrate movement into these types of activities.
Here is a favorite that just simply teaches that music can move upward and downward. It is on old children's song called The Bear Went Over the Mountain. If you don't know the song you can find a lot of versions on YouTube. I like this one the best because the video shows the bear going up and then the bear going down. That is exactly what we are teaching today.

Now that you know the song here is the arrangement I did with my kids. We sang the song and then we walked up the mountain on our instruments and then sang the second part and walked down the mountain. We used small xylophones and turned them sideways so as we played we were actually going upward and downward on the instrument. If you use a piano you have to explain that upward moves from low to high and downward moves from high to low. With bar type of instruments it helps to remember that large is low and small is high. So the kids can organize bells from low to high. It you want to play around with the water glasses use glasses that are all the same and help the children to see that the amount of water changes the pitches from low to high.
See below for other ways to create melody instruments if you do not own one that the children can play.
Creating Melody Instruments: Check out these sites:
WATER GLASSES: This site has instructions for creating a "xylophone" out of glasses filled with water. This would be fun to do and I wouldn't worry at all about creating the perfect scale. The point to the lesson would be that you are creating a set of pitches that go from low to high.

Here is a simple scale song that can be used with Boomwhackers®.
(C) Ebeneezer Sneezer
(D) topsy turvy man
(E) walks upon his elbows
(F) anytime he can
(G) dresses up in paper
(A) everytime it pours
(B) whistles Yankee Doodle
(C') everytime he snores
(C' B A G F E D C) Oh Ebeneezer what a man! (fast descending scale)
Here is a video where you can learn to sing this very simple song. She is playing it on the piano at the same time so if you have a piano you will be able to quickly be able to both play and sing the song.

This is a good sing-a-long version that is much more fun for singing.

You will notice that it says it is color codes for boomwhackers. Boomwhackers are incredibly fun instruments that are made of colorful tubes. For $20 you can buy the basic set and play this song and lots of other songs.

Another option is an 8 note glockenspiel. Here is one at Amazon for $13.99.

The advantage of the glockenspiel is that a child can play the song easily by themselves whereas boomwhackers were more designed for a group to play, each one playing one note.
