Evidenciar que a cor percecionada de um objeto depende do  material de que é feito e da luz que nele incide.

This scenarion intends to have students reflecting on their knowledge related to the phases of the Moon and addressing some misconceptions related to its influence on us.

As children, we’re taught to paint cold things blue and hot things red. In science we learn that blue things are actually far hotter than red things! In this lesson, we will learn how hot objects radiate energy as light of many colors following what is called a black body curve.

The solar system is littered with Ice. The bulk of this material orbits quietly in the outer Solar System, but sometimes something disturbs the ice and it comes plunging in toward the Sun. In this lesson, we will discuss comets, how we explore them, and how they brought water to worlds like Earth.

Today, we are able to study the universe in many colors that can’t be seen with our eyes. From detecting X-rays, to listening to the radio universe, we are able to use digital detectors to “see” hidden aspects of distant objects. In this lesson, we will review the electromagnetic spectrum.

Much of the evolution of the universe can be described through the pull of gravity and push of pressure. Gravity condenses gas, it heats up, and if it can, it expands, and if it can’t, stars are formed. In this Hangout, we will consider the gas laws, and look at different kinds of nebulae.

Our universe started as a fog of particles, but slight variations in density allowed the formation of stars, galaxies, and the large-scale structures of the universe. In this lesson, we’ll discuss early structure formation and fast-forward to today’s stars with planets.

The Earth is warm because energy created in the core of the Sun is able to travel from the Sun’s Core to its surface, and then shine through space all the way to Earth. As it travels, the light is transformed from deadly high-energy particles to the nice warm light that keeps us alive. In this lesson, we will discuss the primary ways energy is transported: convection, conduction, and radiation.

We can’t observe how the universe formed, but scientists are still willing to say that we know the universe was created through a Big Bang. In this lesson, students will learn the three main lines of evidence for the Big Bang: the universe is expanding, the Cosmic Microwave Radiation, and the mixture of chemical elements.

Everything in our universe is made up of a very small numbers of particles, and is controlled by just four forces. In this Hangout, we will discuss these basic building blocks of everything.
