Who knew studying rocks could be so much fun. This week, Tessa learned how different types of rock form with some tasty kitchen demonstrations.
- Read the igneous rock section (pages 15-19) from A True Book: Rocks by Ann O. Squire.
- Read "Granite" (page 8), "Obsidian" (page 9) and "Basalt" (page 7) from Rocks, Fossils & Arrowheads by Laura Evert while examining samples of the same rocks.
- Completed Evan-Moor ScienceWorks for Kids: Geology, Grades 1-3 "Rocks Are Formed In Different Ways - Lollipop Rocks" (page 37).
 |
| When magma (melted rock) pushes up through the Earth's crust it cools into solid igneous rock. Tessa and I made candy lollipops to demonstrate the process. |
 |
| Tessa enjoyed her igneous rock lollipops, which we flavored with bubblegum candy oil. |
Tuesday
- Read the sedimentary rock section (pages 22-23) from A True Book: Rocks by Ann O. Squire.
- Read "Limestone" (page 12), "Sandstone" (page 13) and "Shale" (page 14) from Rocks, Fossils & Arrowheads by Laura Evert while examining samples of the same rocks.
- Completed Evan-Moor ScienceWorks for Kids: Geology, Grades 1-3 "Rocks Are Formed In Different Ways - Lot-O-Layers" (page 39).
 |
| Sedimentary rock is made from layers of mud, sand and seashells. Over time, pressure and heat cause the layers to stick together and form new rocks. Tessa assembled and then we baked this layer cookie to demonstrate to process. |
Wednesday
- Read the metamorphic rock section (pages 24-26) from A True Book: Rocks by Ann O. Squire.
- Read "Gneiss" (page 15), "Marble" (page 16) and "Slate" (page 17) from Rocks, Fossils & Arrowheads by Laura Evert while examining samples of the same rocks.
- Completed Evan-Moor ScienceWorks for Kids: Geology, Grades 1-3 "Rocks Are Formed In Different Ways - Munchies" (page 38).
Instead of following the recipe provided in ScienceWorks, we used a few pieces of refrigerated break-off cookie dough to demonstrate how metamorphic rock is formed, which was a much easier means to the same end.
Following Monday
- Completed Evan-Moor ScienceWorks for Kids: Geology, Grades 1-3 "Rocks Are Formed In Different Ways - Summary Activities" mini book (page 40).
- Read "Conglomerate" (page 11) from Rocks, Fossils & Arrowheads by Laura Evert while examining a sample of the same rock.
- Completed a similar activity to Evan-Moor ScienceWorks for Kids: Geology, Grades 1-3 "Rocks Are Formed In Different Ways - Make Conglomerate Rocks" (pages 41). The version we used was entitled "Making a Rock at Home" (pages 30-31) from Rocks and Minerals by Steve Tomecek.
 |
| Tessa layered school glue, sand and pebbles in a small plastic cup to create a conglomerate rock of her own. |
