Exothermic and Endothermic Reactions: 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
Teachers Love This STEM Activity
Janice ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ Extremely Satisfied
Wow! What a great unit with interesting labs…my students loved seeing the temperature drop or rise right before their eyes! Great STEM engineering integration. The students use the science and engineering practices and really came up with some great prototypes. Loved this whole unit. Really well designed.
Cathy ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ Extremely Satisfied
I used this for the eighth grade Utah SEEd. It is a great resource and aligns well. The slide show was great for teaching concepts and the students loved the dramatic labs! We could see the temperature changes immediately! Awesome!
**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. Since this lab includes real labs with chemicals, students will need safety goggles.
