8. Kinetic Energy to Potential Energy: Relationship in Different Energy Types

Kinetic energy and potential energy are created differently. In this lesson, we will dive into different types of energy, and how they can be transformed into other types of energy.

Chlorophyll: Absorbing Light Energy for Photosynthesis

9. Chlorophyll: Absorbing Light Energy for Photosynthesis

In photosynthesis, chlorophyll and other pigments absorb wavelengths from sunlight, which excites the electrons contained in them. Discover the process of how light energy is absorbed by chlorophyll and why it is important for the next steps of photosynthesis.

Electric Motors & Generators: Converting Between Electrical and Mechanical Energy

10. Electric Motors & Generators: Converting Between Electrical and Mechanical Energy

Both generators and electric motors are common devices in everyday life, but how do they work and what is the difference between them? In this lesson, we'll explore both of them, which may produce different results but are actually more similar than they may seem.

First Law of Thermodynamics: Law of Conservation of Energy

11. First Law of Thermodynamics: Law of Conservation of Energy

The first law of thermodynamics, also known as the law of conservation of energy, says that energy cannot be created or destroyed. Explore the first law of thermodynamics, see how energy can only be transformed but not created or destroyed, and discover some examples of the practical application of this law.

Renewable & Non-Renewable Resources: Definition & Differences

12. Renewable & Non-Renewable Resources: Definition & Differences

Resources naturally replenished by the environment are Renewable Resources, whereas those which replenish too slowly for use, or not at all, are non-renewable. Explore the implications and differences of these two resource types.

What Are Fossil Fuels? - Definition, Advantages & Disadvantages
