Guiding Questions 1. What is matter? 2. We cannot see air, so is air matter? Everything in the universe is made of matter. Yes, everything - even you! Watch this short video to learn basic information about matter and the three states of matter; solid, liquid, and gas. Check out the links at the end of this blog for more helpful websites about this topic. Water is a type of matter. Like all matter, it can take the form of a solid, liquid, or gas.
Standards For This Lesson 5-PS1-1. Develop a model to describe that matter is made of particles too small to be seen. 6.MS-LS1-7(MA) Use a particulate model of matter to explain that density is the amount of matter (mass) in a given volume. Additional Resources

Remember, NEVER look directly at the Sun! Guiding Questions 1. What are lunar and solar eclipses? 2. Why do they occur? Sometimes, the orbits of the Earth, and Moon cause them to form a line with the Sun that creates a shadow, or umbra, to occur as the Earth or Moon block the light energy from the sun. These are a very special events because they do not occur frequently! These special events are called a lunar eclipse and a solar eclipse. I hope that you have the opportunity to observe a lunar or solar eclipse in your lifetime! There will be a partial lunar eclipse visible in our area the night of November 29, 2020. The next total solar eclipse that will be visible from parts of the United States will occur on April 8, 2024. You can ask your science teacher to help you understand how to observe these eclipses. Check out the links at the end of this blog for helpful websites about when to observe eclipses. Note: These diagrams are not to scale. Activity

Guiding Questions 1. How does the Moon move around Earth? 2. Why does the shape of the Moon appear to change? When the Moon is a big, bright circle in the night sky is is very easy to notice! The full moon is the brightest object in our night sky. But, if you observe the moon each night you notice that it appears to change shape. For about two weeks after the Full Moon phase Earth's moon appears to become smaller, and smaller, until finally it is no longer visible. If you wait a few days, you can see the Moon again, just after the New Moon phase. Watch it for another two weeks as it appears to grow bigger, and bigger! Ultimately, it becomes a big Full Moon again, and the approximately four week cycle continues. Why does this happen? One more thing that is important to know when you are learning about the Moon is that Lunar Phases and Moon Phases are the same thing. "Luna" is another name for Earth's moon. Diagram of the Moon's phases: The Earth is at the center of the diagram and the Moon is shown orbiting (dashed circle). The Sun lights half of the Moon and Earth from the right-side. The phase of the Moon is shown next to the corresponding position of the Moon in its orbit around Earth. The phase is as seen in the Northern hemisphere of the Earth.

Guiding Questions 1. What can we observe (see) in the night sky tonight? 2. Can we see a planet in the sky? 3. What does the Moon look like tonight? Note: This activity is designed for the nights of April 1 - 6, 2020, during the hour after sunset, in the area of Lynn, Massachusetts, but the activity can be done with success anytime, and anywhere. This Space Science activity is different from the first four (4) activities I posted. I want you to go outside on the next clear night, soon after sunset, and look for the Moon. It should be almost right above you. Next, look towards Boston in the west where the Sun just set, and try to find the brightest star in that area. This very bright star is not really a star. It is the planet Venus! Of course, you also see some stars in the sky tonight. Which object is farther away from Earth, the Moon, Venus, or the stars you see tonight? After you enjoy looking at the beautiful night sky, I want you to draw a picture of what you observe. Include the date and the time of your observation. You can also label the Moon and Venus. Scroll or move down on this page for the complete instructions for this activity. The image below has a link to a web page with a short video to help you find objects in the in the night sky this month. Simply, click here or on the picture with your cursor to open the new web page so you can watch the video.
