Learning about fossils and making a few molds and casts of our own.

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.

Seeds, Spores, and Cones

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.

STEM CLUB: Water Filters

In our after school STEM Club, students have been working to construct water filters. Their objective is to build the least expensive (from commonly available parts) water filter, that cleans the water the best, and the quickest.

Students purchase materials and evaluate their possible scores, given how much money they spent, using a cost analysis rubric. Next, they test their materials to see what works best and redesign their filters if needed.

The water is judged on color, clarity, smell, and particles.

Students have done an amazing job designing, creating, and testing their filters!

Phase Changes in a Chemistry Lab

Last week, we prepared for our upcoming unit in chemistry by performing an experiment with dry ice.  Students observed Mr. Thompson’s demonstration of  how dry ice is frozen carbon dioxide that happens to sublimate.  A unique phase change for our class to observe and one that was a lot fun!
