This Power Point presentation provides a thorough overview of the water cycle, setting the stage for the Water Cycle Lab activity. Students, working in teams of two or three will observe how the heating (w/hot plate) and cooling (w/ice) of H2O produces the two key phase changes that drive the water cycle. They will observe evaporation (indirectly), condensation, and yes! - even precipitation all within the confines of lab beaker. Teachers are responsible for all safety instructions regarding the

A fantastic way to introduce the topic of weather to beginners. This includes a printable weather survey for students and a Power Point keyed to the survey. This activity provides a visual exploration of weather ingredients, weather phenomena, reasons for the seasons, and weather instruments. No better way to get students excited about weather studies in school and at home.

An image rich, introductory Power Point that examines the molecular and macro views of the temperature dependent conditions commonly called the "states of matter". This Power Point is not intended for note taking; some prior knowledge is required for proper narration.

This Power Point covers the fundamental of static electricity including, contrasting current electricity, the principle of shifting/standing electric surface charge, the law of electrostatic attraction and repulsion, and lightning.

This simple 5 page mini-book examines the common observations produced by Earth's orbit around the Sun. Includes periodicity, solstices and equinoxes, seasonal temperature variations, opposite seasons, and leap "year".
