Changes in Nature

To start our unit on life cycles, we discussed the changes that we can observe in nature. Since we have been observing different things in the science center, and recently the flower experiment, we are used to making good predictions and observations. We also have been learning to keep science journals where we write down our observations and any questions we have.

We came up with a list of the changes that we can observe in nature:

• Leaves change colors.
• Leaves fall off trees.
• The weather changes. (rainy, sunny, cloudy, windy, snowy)
• Flowers and trees grow and die.
• The seasons change. (Winter, Spring, Summer, Fall)
• Animals and humans grow up.

In our long discussion about changes in nature, we talked a lot about animals that change, like tadpoles and caterpillars. We learned that these are called life cycles. It happens again and again, just like a circle goes around and around.
