Candy Atoms: Isotopes Intro for Grade 1
By Celena A.
A short candy-based science lab packet that introduces isotopes through counting, rounding, and reading simple periodic table data. Designed for first graders to build number sense and early science vocabulary during a single 30-45 minute hands-on session, though the current content is written at a middle school level and will need significant adaptation.

Teacher Guide & Tips
- Context: Be aware the current packet uses atomic numbers, atomic mass, protons, neutrons, and rounding to the nearest whole number, which are well above first grade. For a 1st grade version, consider replacing the periodic table work with simple sorting and counting of candy colors, which keeps the candy-lab hook.
- Discussion question: "How many candies of each color do you have? Which color has the most, and which has the least?"
- Scaffold: Provide pre-sorted candy cups, picture cards of each color, and tally mark templates so students can count by pointing and moving pieces.
- Extension: Advanced students can compare two cups, write which has more or fewer using "more than" and "less than," or try grouping candies into tens.
- Time: Plan roughly 30-45 minutes for sorting, counting, and a short class share-out, with additional time if weighing candy with a simple scale is included.
