After we started the year reading about and painting volcanoes, and I was hunting around for a good read-aloud, I was reminded of the fantastic book The Twenty One Balloons, based on the real-life eruption of Krakatoa. This broadened out our study in so many fun ways. We were able to study, paint, and build hot air balloons while we continued our rocks study. So after we painted our volcanoes, the next week we had to paint hot air balloons flying over the volcanoes, of course. We also learned a lot about Krakatoa, San Francisco (including where they are geographically) and the time period in which The Twenty One Balloons is set.
|This is O Boy's volcano and hot air balloon. I love watching him take the basics of a task and turn it into so much more than I ever imagined.|
|Here is the Little Sweetie's volcano - and it even has a line of magma running down the center! Flying above it is a hot air balloon painted by Mr. T.|
|Using the GEOLOGY ROCKS unit study book we did several great experiments on rocks, crystal formation and the different kinds of rocks. Here we are making some sugar crystals that we cooled slowly to see how igneous rocks appear when they cool slowly.|
|One thing O Boy has enjoyed doing this year is coming up with snacks that go along with whatever we are studying. On this day he made little "volcanoes" out of halved apples, peanut butter and craisins (performing as magma and lava).|
|Mr. T is really working on learning his beginning skip counting sets. Here he is, having just lined up all the 10s to 100!|
|Here are the kids with all the materials to make some delicious sedimentary rocks. We layered all sorts of things to make some beautiful layers: raisins, rice crispies, m and m's, and chocolate chips.|
|Igneous rocks (melted chocolate quickly cooled over frozen blueberries).|
|And now can I eat it??|
|An experiment to see how crystals look when they are cooled quickly.|
|Rock candy! It shatters easily and is delicious to munch.|
|The two kinds of crystals: the ones on the stick were cooled slowly and the round circle cooled quickly.|
|Here's Mr. T and his wonderful helper/teacher, Super Ginny, working on some tissue paper hot air balloons.|
You can find the patterns for these here.
|This was a color by number I worked on with Mr. T. It was pretty challenging for him because some of the spaces were so small. But he stuck it out and I had him cut it out to add a little cutting to the activity.|
After we read about the amazing houses in The Twenty One Balloons, I had the boys write a bit about an amazing house they could pretend to live in. O Boy got to pick his photo out. Here's what they came up with:
|My house is on Mars. My house can fly. I go to my house on Saturday. My house rocketship is in a secret place!|
|Mr. T's says: Our house is a bulldozer. My house is silly.|
|One other fun thing that O Boy did was to illustrate sections of The Twenty One Balloons as we read it. Here is his picture of the Airy Go Round.|
|Here is his picture of the diamond mines.|
|Mr. F and Professor Sherman holding diamonds.|
|This is his picture of Krakatoa, with the green grassy area surrounded by their houses (next to the active volcano!).|
Here is another fun thing O Boy came up with during this unit: a Volcano Book he worked very hard on one afternoon.
|Cover of the book|
|Different kinds of volcanoes. If you know your volcano types, you'll recognize these!|
|A volcano in action. I think he was also showing the different kinds of things that shoot out of volcanoes.|
|A cross section of a volcano, showing the magma coming out.|
|How a volcano grows. When he showed this to me, he said, "Just like that volcano in that field with that farmer." You'll have to read about the volcano discovered in Paricutin, Mexico to see what he means.|
