The Mesozoic Era began around 250 million years ago and ended about 65 million years ago. Both it's beginning  and end are marked by major extinction events. The Mesozoic Era is often called the age of the dinosaurs because they were Earth's dominant animals during this era. It's also the era when the first mammals and birds appear in the geologic timeline. T he Mesozoic Era is divided into three periods: the Triassic, the Jurassic, and the Cretaceous.  If you haven't already, be sure to check out my other posts about geologic history: Learning About Geologic History- The Paleozoic Era Learning About Geologic History- Fossils Animals of the Mesozoic: Triassic - The end of the previous geological period is marked by a widespread extinction event that resulted in the loss of around 90% of Earth's species. The Triassic Period began with Earth as a sparsely populated planet with low biodiversity.  The two groups of animals that dominated the early Triassic  were the Arc

While browsing through books for a unit study I'm working on, my girls and I came across a book about the Australian spotted jellyfish. They were fascinated by the pictures and asked me to read it to them. This ended up inspiring an entire day of jellyfish themed learning. Below are instructions for the activities we did and links to the resources we used. Interesting Facts About Jellyfish -Jellyfish are not actually fish at all.

They do however have a simple nervous system that allows them to detect light, vibrations, and chemicals in their environment. -Some sea jellies have bioluminescent organs that make them glow in t

  Japan might be my favorite country unit study we've done yet! We found several awesome art and craft activities to try, made an erupting volcano, learned about the Pacific Ring of Fire, made teriyaki chicken, and lots more!
