Learn the basic concepts of electricity: positive and negative charges, current flow, open/closed circuits and what shocks are. Includes a hands-on activity.
Studies the chemical process of photosyntheses that creates a plant's unique ability to produce food and oxygen from sunlight. Diagrams and photomicrography illustrate the role of each part of the leaf in this process detailing how chloroplasts felled with green chlorophyll become eenergized when exposed to light. Animations show how this related to the release of oxygen through stomata and the creation of sugars that can be stored for future use by the plant. In a hands-on experiment, students investigate whether or not a plant needs light to make food.
Explains what heat energy is and how it is used, demonstrates how heat moves through conduction, convection, and radiation, and discusses melting point, boiling point, and related topics.
