Charting the Moon

Sugar crystal growth is observed as an example of physical change and cabbage juice pH indicator is used to demonstrate chemical change. The crystal growth is tracked over five days. The cabbage juice experiment is involved and can also...

Why does it look like there is a man on the moon? Why does the moon look different every night? These are the focus questions of a lesson that prompts class members to observe and record the nightly changes of Earth's natural satellite.

Watch an entire month flash before your eyes with this fun phases-of-the-moon flip book activity.

What better way to make predictions about future weather and climate patterns than with actual climate data from the past? Young climatologists analyze data from 400,000 to 10,000 years ago to determine if climate has changed over time....

The water cycle is one of earth's most easily observable processes, but demonstrating each step within classroom walls can be a challenge. Through a series of videos and quick demonstrations, cover each aspect of the hydrologic cycle in...

Is there more to evaporation than just less liquid? Show young scientists the energy transformation that occurs during a phase change through a series of simple experiments. Lab partners place drops of water, ethanol, and ethoxyethane on...

Sixth graders learn that the moon orbits the Earth in a predictable cycle. Each learner engages in a two-week observation of the moon. They sketch its appearance, and take note of its position in relation to objects in their yard. Some...

Want to add a wow factor to your current chemical changes lesson plan? Try a microscale experiment with colorful precipitates! Partnered learners conduct 10 single displacement reactions and record their observations.

Students explore the water cycle and associated phase changes. They predict what happens to the mass of an ice cube in a Ziploc bag, discuss and act out phase changes and diagram the water cycle.

After reviewing the causes and effects of climate change, students become observers for "Plant Watch," a program to monitor the effects of climate change on plants. Students record blooming and leafing dates for selected local species...
