5th Grade Science Update
When we come back from break we will start our new unit called Water Planet. We’ll begin with a survey of the solar system, finding out about the properties of the planets, moons, comets, and asteroids that orbit our magnificent star, the Sun. We’ll ponder how the force of gravity keeps Earth and the other planets in orbit around the Sun.
We will then turn our attention to Earth, the water planet. We’ll investigate the variables (temperature and surface area) that affect the evaporation of water and develop explanations for the formation of dew and frost. We’ll place containers of water and dry soil in the sunshine to find out if they heat up equally. We’ll use the results of these experiments to consider how uneven heating of Earth’s surface produces convection currents. These concepts come together in the form of the water cycle. Finally we’ll develop the big idea of weather.
You can increase your child’s interest in Earth’s place in the solar system and the importance of water by asking him or her to talk about the science investigations. Check out the weather maps in the daily newspaper or on-line or watch the evening news for weather reports. Find out more about where the water that flows from your faucets originates and how it gets to your home.
