Chemical Bonding & Chemical Reactions - FREE Video Worksheet - Middle School Science for 2025 & 2026

Why does iron rust? How does baking soda and vinegar fizz? What holds water molecules together? The answers all come down to chemical bonding and chemical reactions - the processes by which atoms connect, rearrange, and transform into entirely new substances. This is where chemistry gets exciting! [Preview this free video here on YouTube] NGSS Standards: Perfect for 6th, 7th, and 8th grade students studying physical science and chemistry. This video aligns with 🎯 NGSS standards MS-PS1-2 (analyzing and interpreting data on properties of substances before and after interactions) and MS-PS1-5 (developing and using a model to describe how atoms rearrange during chemical reactions). TEKS Addressed: 🎯 Middle School Science: 8.6.B - The student is expected to use the periodic table to identify the atoms involved in chemical reactions. 🎯 8.6.E - The student is expected to investigate how mass is conserved in chemical reactions and relate conservation of mass to the rearrangement of atoms using chemical equations, including photosynthesis. ⭐ What's Covered?: ✅ What chemical bonds are and why atoms form them ✅ Ionic bonds: electron transfer between metals and nonmetals ✅ Covalent bonds: electron sharing between nonmetals ✅ How to read and write basic chemical formulas ✅ What happens during a chemical reaction ✅ The Law of Conservation of Mass: atoms are never created or destroyed ✅ How to identify and balance simple chemical equations ✅ Real-world examples: rust, combustion, photosynthesis, cooking What will the students be doing? ● Students will be given either a printed or digital handout to record answers on. ● Either individually or as a class watch the video ● Then, they will use the video and their own knowledge to answer the questions. ● Use questions to spark discussions and apply information beyond the page!
