Bellringer – Jan 31

Explore the fascinating world of chemical reactions and energy changes in this engaging bellringer activity. Students will analyze the effects of mixing two chemicals, leading to temperature changes and energy absorption or release. By examining specific data and discussing feedback on OGT review questions, learners will deepen their comprehension of endothermic and exothermic processes. The activity encourages critical thinking about experimental results and reinforces scientific concepts through hands-on exploration.

Presentation Transcript

  1. Bellringer – Jan 31 • The temperature rises when you mix two chemicals together. In this reaction, energy is • Absorbed • Released • Not absorbed or released • What did you think about the OGT review questions on Study Island? Were they hard, easy, etc.?

  2. Bellringer – Feb 4 • Looking at the following data from a chemical reaction, was energy absorbed or released? • How do you know?

  3. Bellringer – Jan 31 • The temperature rises when you mix two chemicals together. In this reaction, energy is • Absorbed • Released • Not absorbed or released • What did you think about the OGT review questions on Study Island? Were they hard, easy, etc.?

  4. Bellringer – Feb 4 • Looking at the following data from a chemical reaction, was energy absorbed or released? • Answer: Absorbed • How do you know? Temperature went down meaning that the reaction had to take in energy
