Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

Use the Zoo Calendar (page 1 of PDF) to involve learners in interdisciplinary, whole language, and writing activities about ecological concepts.

In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.
