We made eggshell geodes in science. Some students prepared a super-saturated solution of hot water and Alum powder. This process demonstrates how geodes form in sedimentary and igneous rocks! Here is a link to complete the experiment at home: https://sciencebob.com/eggshell-geode-crystals/#:~:text=The%20hot%20water%20cooks%20the,the%20egg%20using%20your%20fingers.&text=Pour%20half%20a%20cup%20to,Stir%20it%20until%20it%20dissolves.
We had a great time building atoms out of M&Ms and molecules out of toothpicks and gumdrops! Students learned to find the atomic number, atomic mass, symbol, and structure of elements on the periodic table. Students distinguished between elements, molecules, and atoms.
Our class studied states of matter and phase changes. One of the more difficult concepts was sublimation (the change from solid to gas). We used dry ice to demonstrate this phase change. After which, we did some awesome experiments using the dry ice!
****Dry Ice should not be handled at home and requires a well ventilated room. We ran fans and opened all windows/doors. All the dry ice was only handled by the instructor using gloves, tongs, and protective eye wear. ***
On Friday, we learned about four types of fossils: mold and cast, trace, true form, and resin fossils. Students also participated in several activities, including, making their own molds and casts, digging for fossils, and classifying fossils.
On Tuesday, students will take their fossil finds and creations home with them.
We have been studying seed plants and seedless plants in class, and relating it plant life cycles!
Last week we finished our science lab on vascular plants. We wanted to answer the question, “What allows some plants to grow tall and still have support and obtain nutrients and water?”
Analyzing owl pellets as a class to better understanding food chains in ecosystems, and the importance of “balance” in nature.
Good Afternoon Everyone! As a class we are studying plants and their seeds. If your child finds any type of native species seeds around your town, our class would love to have them. Our class is looking for seeds, cones, and spores. Examples include acorns, sunflower seeds, pine cones, maple seeds, and fern spores. Please try to send seeds to class in a ziploc bag. We will be collecting seeds all week! Have a great night.
