Non-living things are inanimate objects or forces with the ability to influence, shape, alter a habitat, and impact its life. Some examples of non-living things include rocks, water, weather, climate, and natural events such as rockfalls or earthquakes.
Living things use energy. They move or change shape. They take in food and get rid of waste, and they have babies, or reproduce.
Humans, insects, trees, and grass are living things. Nonliving things do not move by themselves, grow, or reproduce. Through this discovery which shows that water has a memory, according to scientists, a new perception of water can be formed.

Let the kids decide where it should go and realize there is no absolute correct answer on this.
Which One is Alive? Have the students look at the two bags on the table and describe the powder that is inside each. The powders are 1 corn meal and 2 yeast but don't tell them. Ask the students if they think the powders are alive. Add a teaspoon of sugar to each bag. Tell them that if the powder is alive, it needs to eat. Add 2 tablespoons of warm to slightly hot water to the two bags.
Tell them that if they are alive, they will need to have water. Close up the bag and make sure there is some air left in the bag because if they are alive, they need to breathe. Close the bag and observe the solutions for 5 minutes. While they are waiting, discuss their observations and decide if they think either powder is alive.
