This is my first entry under a new tab Resources, intended primarily for astronomy education to complement the astronomy topics in the Philippine K to 12 Science Curriculum. Teachers in the secondary level, science educators, students, as well as astronomy enthusiasts will benefit most from the teaching resources in this newly-created page.

What do you think will happen if an asteroid or a comet hits Earth?

Evidence of impacts caused by asteroids and comets have been found in various places on Earth and scientists believe that in the distant past, an asteroid or a comet impact might have led to the extinction of dinosaurs.

In this activity, students will simulate the formation of a crater using some common materials like marbles, flour, and a basin. It is intended for Grade 8 students, particularly, for the topic ‘Other Members of the Solar System (Comets, Meteors, and Asteroids)’ in the Grade 8 Science Learner’s Material (Unit 2, Module 3) published by the Department of Education. They will learn what an impact crater looks like and how the size of an object affects the size of the crater formed. This activity effectively illustrates to students that other members of the solar system, particularly comets, meteors, and asteroids, are capable of causing catastrophic effects in the event of an impact with Earth.

There will be a Venus-Moon pairing a few hours before sunrise (3-5 am) on September 13, 2012. This pairing also presents an opportunity to spot Venus even during daytime, that is, while the Sun is up and the sky is still blue. The event requires no telescope and will be visible to the naked eye.

Identify constellations and planets using Google Sky Map! This application uses the on-board array of sensors in a smartphone to determine the location and orientation of the phone and generate a real-time ‘map of the sky’. To identify objects, just hold the phone against the sky and the application automatically plots the current sky objects. Read more.

Earlier today I organized a solar observation with the University of the Philippines Astronomical Society (May 13, 2012) in preparation for the upcoming May 21, 2012 annular solar eclipse and the most awaited June 6, 2102 Venus transit.
