On the 8th of February 3rd and 4th went to Blackrock observatory for a Mars workshop. We only go to school around the corner but we went to the observatory with 2 big taxis because the weather was bad. We looked around the castle and then we did experiments about asteroids. We dropped rocks and more stuff in boxes of sand and observed the 'craters' that we made. We did a game where we saved the planet. We also threw asteroids on the earth with a simulator. We looked at Mars in a program called stelarium and we explored the castle. This was (In my opinion) the best school trip EVER.
