I want to learn how to make a terrarium for my daughter's birthday.

First, you'll need some supplies such as glass or plastic containers with lids, soil, gravel, stones, moss, and plants of your choice. You can also use small decorations like figurines or shells if desired. Next, prepare the soil mixture by mixing one part potting soil with two parts sand. Fill each container about halfway with the soil mixture. Place the decorative items in the container, then add the plants and more soil until it is level with the top of the container. Finally, water the soil lightly so that the entire terrarium is damp but not saturated.
