Title: Interactive Notes: 6.E.1 Earth Moon Sun Review Notes: Interaction: 6.E.1.1 Our planet Earth revolves (circles around) the Sun (the largest star in our Solar System). The moon is a natural satellite (an object that revolves around another object in space) of Earth which revolves around our planet. The moon does not make its own light. Create a Venn Diagram to compare and contrast the definition of “revolve” with the definition of “rotate.” Gravity is a force existing between any two objects with mass, which keeps the planets and moons in place. Because of the moon’s rotation, our moon looks different from Earth every few nights. The different shapes of the moon are called phases, and they repeat in a cycle every 29.5 days. The gravity of the Sun and Moon as well as the Earth rotation (spinning on its axis) have a major impact on the Earth’s ocean tides. Ocean tides follow a predictable pattern. The rotation of the Earth causes all parts of the Earth to have periods of day and night. Because the Earth’s axis is tilted while Earth revolves around the Sun, we experience different seasons. The tilt of the Earth’s axis also results in the seasons being opposite in the Northern and Southern hemispheres (upper and lower halves of the Earth). Write at least 1 sentence and draw an illustration for each of the following questions: 1. Explain why we have day and night. 2. Explain why we have seasons. 3. Explain why a year is a different length of time depending on which planet you are on. Create AND answer a quiz question you think might be on the EOG regarding the Earth, Moon, and Sun. Notes: Interaction: 6.P .3.1 Energy is the ability to do work or cause change. Energy can be transferred from one system to another in different ways: Thermal, energy in the form of heat Mechanical, energy that an object has because of its motion Electrical, when an electrical source such as a battery is connected in a complete circuit to an electrical device Radiant, by electromagnetic waves. Heat flows from warm objects to cooler objects, until both objects are Draw and label 4 pictures to show an example of each: Thermal, Mechanical, Electrical, and Radiant energy. Answer in full sentences: Can one type of energy be converted (changed) into another type? Explain how you know. at equilibrium (the same temperature) Provide an example of each: Conduction, Convection, and Radiation. Thermal energy is transferred through materials when atoms bump and collide against each other. Heat travels through solids, primarily by conduction: When two items of different temperatures are touching. Heat is circulated in fluids, both liquids and gases, through the process of convection: heat rises and cold fals in a fluid until it is all the same temperature. Radiation is energy that travels across distances in the form of electromagnetic waves. 9 Flash cards to make: Energy Thermal Mechanical Electrical Radiant Equilibrium Conduction Convection Radiation 6 Flash cards to make: Revolve Sun Satellite Gravity Phases Rotation Choose 2 types of thermal energy transfer(conduction, convection, radiation) to compare and contrast in a Venn Diagram.
