Go on a tadpole hunting adventure
Get your feet wet (or pull on some gumboots!), make a stocking net from a wire coat hanger and head for a still pond or creek. Reach as far as you can into the pond and drag your net along the bottom where the little tadpoles are hiding. Lift your net half way out of the water to see if any tadpoles are splashing around in the bottom of the net. If you catch one, scoop it out with your hand and place it in a container filled with water from the pond.
