The Night Hike was the Coolest Thing Ever!

In the night hike, I heard a mourning dove and saw many star constellations. Red Tail showed us how to find north. One way is to find Cassiopeia, then look at its middle 3 stars, those stars point toward Polaris, the north star. Another way is to find the Big Dipper. It points toward Polaris too!

Red Tail also told us about rods and cones. Hawks have cones which makes them see color. Owls have rods that make their vision into night vision. Rods have rhodopsin, and cones see color. Another thing was that Red Tail gave us these crystals that glow when you break them with your molar teeth.

That was the best hike ever. Oh, and in the night hike we saw a meteorite. Red Tail told us that the meteors falling were pushing against the air making friction. That's why meteors never made it to land, they burn out in the atmosphere!
