Polydensity bottles are made with salt, isopropyl alcohol, water, UV beads, and pony beads. These materials are easily accessible and relatively inexpensive. With the polydensity bottles, students can engage in sensemaking related to density, molecular properties, solubility, and other concepts supported by the NRC K-12 Framework. Students can be challenged to complete calculations and create their own bottles, or teachers can make bottles to be used as an introductory or anchoring phenomenon. This session will provide multiple ideas on ways to use these interesting bottles to give students at multiple levels the opportunity to engage in sensemaking and Science Practices. Instructions will be given for creating bottles with multiple recipes, and sources of instructional materials will be provided to participants.

TAKEAWAYS:
Poly density bottles are an effective and inexpensive way to provide a discrepant event to intrigue students. Students at various levels can engage with this phenomenon to engage in sensemaking as they employ several different concepts in Physical Science.

A middle school PLC observed that students were not retaining or using content specific vocabulary or completing teacher provided practice. Through a coaching partnership, educators researched and determined to prioritize the following learning: conceptual understanding, explicit instruction, connection between words, multiple interactions with words, and discourse among peers. First, teachers minimized the words in each unit to focus only on Tier 3 and Tier 2 words. Next, the educators placed the words in a flow chart on a large wall showing connections between words. Teachers developed conceptual understanding during instruction and ways for students to interact with each word. Examples included; labs, readings, definitions, and discourse with peers. The teachers intentionally selected strategies to interact with each word such as defining, drawing, comparing, summarizing, discussing, and synthesizing their understanding. Student work was displayed on the interactive wall.

TAKEAWAYS:
Participants will leave with strategies to implement vocabulary instruction in any science content area.

Aligned to Next Generation Science Standards, our collaborative card game called Mountain Rescue engages players in STEM learning while immersed in an authentic and thrilling context: seeking rescue from a plane crash. Designed for grades 5-8, the game is playable in about 30-minutes. Preliminary play-test results indicate that students are engaged and feel the game has value for collaborative learning. During gameplay, players utilize collaborative skills essential to STEM careers by working together to solve puzzles related to electricity, physics, chemistry, and engineering design. Yet, to convert our research into effective classroom practice–we need you. Please stop by our poster and share your feedback with us. We would love to hear your thoughts about gameplay, game design, and potential implementation issues which we will incorporate into our next round of funding. Maybe you would even like to have the next version of Mountain Rescue come to your classroom!

TAKEAWAYS:
Attendees will learn about the collaborative STEM card game called Mountain Rescue. Presenters will share the design, gameplay basics, and research findings. Presenters will engage attendees in lively discourse around necessary improvements and implementation issues.
