On our last day of Dinosaur week, we are learning all about volcanoes -- how they work and how they may have harmed the dinosaur environment. We'll even be doing a fun experiment that you can do at home. Also, our fun fact for the day is: Magma is hotter than lava and can reach up to 2400 degrees F! Wow, that is hot! We usually do most of our baking--like cookies at 350 degrees F. Writing TimeWrite your nameWrite the date: 5-7-20Write the word of the day: LAVAWriting Time Reminders: -Names can be all uppercase, or start with uppercase and then use lower case. -Parents write the date first, then kids write or trace it. -”Word of the Day” words reinforce the weekly theme and provide practice writing letters that may not appear in their names. Parents can talk about the word and encourage a story or drawing -Parents, your children may need help with these tasks, so feel free to practice along with them. Circle TimeRemember from Tuesday, we learned that some people think that there was alot of volcanic activity causing the end of the dinosaurs. Let’s take a closer look at volcanoes. First of all, our Earth is made up of different layers: the crust (where we live), mantle and core. A volcano is a hole in the Earth’s crust. It is usually in the form of a mountain. Between the Earth’s crust and the mantle is some stuff called magma which is made of very hot liquid rock and gases. This mountain has an opening leading down into a pool called a magma chamber. Movement on the Earth’s crust creates pressure underground, the magma gets pushed up through the volcano making it erupt, or explode like a bomb or fireworks!. Each time a volcano erupts, it adds to the layers of the mountain--growing bigger and bigger. The largest volcano is Mauna Loa in Hawaii. One of the smallest volcanoes is Mount Taal in the Philippines.
When a volcano erupts, a lot of things come shooting out into the air. Remember, the magma is hot liquid rock from deep inside the volcano. When it rises to the surface and pushes out, it is then called lava. Lava is also a very hot liquid rock but it flows outside of the volcano. Lava is so hot it can burn everything in its path. When it travels across the land, it is called a “lava flow”. Steam, rocks, gas, and ash are other things that come shooting out! These things can hurt animals, people, or plants that are nearby. A volcanic eruption may have been devastating for dinosaurs. The air was probably cloudy with gases and ash; the plants could have been taken over by lava flows. Volcanic eruptions have been known to knock down entire forests. They can even trigger floods, earthquakes and mudslides. Volcanoes can be dangerous, but they also have some good qualities. The lava and ash will eventually break down and provide good nutrients to the soil. That is great news for growing crops! Some birds use the warmth of the volcano to lay eggs. They bury them in the sand or soil nearby. There are more than 1500 active volcanoes on the Earth. Oregon and Washington are home to many of them. There are 60 volcanoes in Oregon. Mt. Hood is probably the only volcano in Oregon which has erupted in historic times (last confirmed activity in 1865-66) See https://www.volcanodiscovery.com/oregon.html for more information. Can you believe volcanoes exist throughout the solar system!! Other planets and moons have volcanoes. The largest volcano in our solar system is Olympus Mons, found on Mars. Daily Activity - Erupting VolcanoMixing everyday ingredients to make a volcano never gets boring. This recipe came from sciencenotes.org Materials needed:
Directions:
Daily Book JournalThree times a week, help your preschooler to pick out a book and read it together. Then, help your preschooler to create a journal entry using any of these same options from our book bag job.
Extra Activity - Measuring
The table is 5 socks long Book Reading with our TeachersWe have a special surprise for you today- We have 2 readers! Join Ms. Anne as she reads "When Dinosaurs Came With Everything" by Elise Broach AND Hudson's Mom, as she reads "T Rex The Big Scare" by Fran Bromage Fun Activities1. Create your own dinosaur skeleton art using tape! Lay out a skeleton shape with tape, paint your dinosaur (or color with markers), then remove the tape! 2. Make some dinosaur bones. Use the flour/salt recipe from yesterday but instead of pressing an image into the dough, shape it into bones. After the bones dry, paint them to look old. 3.Explore a new park (The Century Oaks Park and Butternut Creek Park are especially fun to walk around, even if you can't play on the playground) 4. Take a VIRTUAL tour of a dinosaur museum! Here is one option to explore: https://naturalhistory.si.edu/visit/virtual-tour See what our Friends are Doing!
