Description
Design a Cold Pack❄️ Students will learn about exothermic and endothermic reactions in dramatic experiments in which they see the temperature quickly rise or drop. They will use this information to design a cold pack. Students will use engineering skills and the design cycle and they will construct a solution.❄️❄️❄️
✅NGSS MS PS1-6 Undertake a design project, engaging in the design cycle, to construct and/or implement a solution that meets specific design criteria and constraints test, and modify a device that either releases or absorbs thermal energy by chemical processes.*
This resource includes:
- an informative slide show
- strategic note-taking guide
- two lab activities
- a STEM engineering activity
- a reading passage
- response pages
- a quiz
- answer keys
**The materials for the labs include thermometers, hand warmers, glass jars, vinegar, baking soda, calcium chloride, ammonium chloride, and water.
The two chemicals listed can be purchased online from a science supply company. A link is included in the terms of service.
****This also includes an engineering activity to fully meet the standard for NGSS MS PS1-6. For the engineering activity, students will need some ziplock baggies, tape, foil, and other easy-to-find household materials.
