Spectroscopy of the Stars. Word Document PDF In this activity, students investigate continuous spectra and emission spectra. If gas emission lamps are not available, the activity can be edited to only investigate the continuous spectra from an incandescent light bulb and mercury emission spectra from a normal fluorescent light. Various spectrum tubes with different gases (EISCO) and a power supply (Elenco) are readily available online for less than $200.
Can We Measure the Diameter of the Sun? Word Document PDF In this activity, students use a pinhole camera to estimate the diameter of the Sun. This is an excellent activity to integrate mathematics with science. Be sure to check out the video "Shadow Illusion" below.
Sunspots. PDF Click to download the observation sheet for recording sunspots. We use Sunspotter Solar Telescopes for safely observing sunspots. Although they are a bit expensive, over $300, they are durable and many students can observe the sunspots at the same time. Students can record observations and compare to current images from the Solar and Heliopsheric Observatory. In addition, students can record their observations over several days to observe the movement of sunspots due to the rotation of the Sun.
Solar Pizza. PDF Click to download the solar pizza activity where students develop a scale model for the relative sizes of the Earth and Sun and the distance between them. This activity permits students to consider was developed by NASA.
How Close is It? PDF Word Doc In this activity, students compare two lights on opposite sides of a room to compare the apparent brightness of lights as a model for the Sun and a distant star. This activity addresses the 5th grade Performance Expectation 5-ESS1-1 and gives students the opportunity to practice the NGSS Crossing Cutting Concept about Scale, Proportion and Quantity.

NGSS Disciplinary Core Ideas
ESS1.A: The Universe and its Stars Patterns of the motion of the sun, moon, and stars in the sky can be observed, described, and predicted.
ESS1.B: Earth and the Solar System Seasonal patterns of sunrise and sunset can be observed, described, and predicted.
ESS1.A: The Universe and its Stars The sun is a star that appears larger and brighter than other stars because it is closer. Stars range greatly in their distance from Earth.
ESS1.B: Earth and the Solar System The orbits of Earth around the sun and of the moon around Earth, together with the rotation of Earth about an axis between its North and South poles, cause observable patterns. These include day and night; daily changes in the length and direction of shadows; and different positions of the sun, moon, and stars at different times of the day, month, and year.
ESS1.A: Patterns of the apparent motion of the sun, the moon, and stars in the sky can be observed, described, predicted, and explained with models. Earth and its solar system are part of the Milky Way galaxy, which is one of many galaxies in the universe.
ESS1.B: The solar system consists of the sun and a collection of objects, including planets, their moons, and asteroids that are held in orbit around the sun by its gravitational pull on them. This model of the solar system can explain eclipses of the sun and the moon. Earth's spin axis is fixed in direction over the short-term but tilted relative to its orbit around the sun. The seasons are a result of that tilt and are caused by the differential intensity of sunlight on different areas of Earth across the year. The solar system appears to have formed from a disk of dust and gas, drawn together by gravity.
ESS1.A: The Universe and Its Stars The star called the sun is changing and will burn out over a lifespan of approximately 10 billion years. The study of stars' light spectra and brightness is used to identify compositional elements of stars, their movements, and their distances from Earth. The Big Bang theory is supported by observations of distant galaxies receding from our own, of the measured composition of stars and non-stellar gases, and of the maps of spectra of the primordial radiation (cosmic microwave background) that still fills the universe. Other than the hydrogen and helium formed at the time of the Big Bang, nuclear fusion within stars produces all atomic nuclei lighter than and including iron, and the process releases electromagnetic energy. Heavier elements are produced when certain massive stars achieve a supernova stage and explode.
ESS1.B: Earth and the Solar System Kepler's laws describe common features of the motions of orbiting objects, including their elliptical paths around the sun. Orbits may change due to the gravitational effects from, or collisions with, other objects in the solar system.
Common Scientific Misconceptions
The Sun goes around the Earth.
The Sun will last forever.
The Sun contains only hydrogen and helium.
