Intentional blur with point and shoot digital? (Lumix LZ7)?

I've been trying to get some blurry waterfall or moving object shots. Whenever I choose slow shutter and turn off the image stabilizer, the picture still comes out clear. The starry-night mode gives you a slow shutter but it's a 15 second minimum---which might work on a waterfall if I get the apature right so it's not overexposed.

I also want to try some panning, moving object shots so the object appears clear and the background is blurry.

I heard a low-ISO can help, but in Intelligent ISO mode, it won't let you change shutter speed, and in normal mode, I can't figure out how to change ISO.

Are there any scene modes that will let me get a blurry shot? It seems like this camera is designed for clear shots, which is nice...except when you want blur.

Thanks for any help!
