Help your students build real understanding of real world stoichiometry through ninety questions that move from basic recognition to genuine reasoning about chemistry concepts.
The set includes questions like "In a mixture, the ratio of salt to water is 1:4. How much water is needed for 2 cups of salt?", "In a recipe, the ratio of sugar to water is 2:5. How much sugar is needed for 25 cups of water?", and "A child weighs 30 kg and the dosage of a syrup is 0.5 ml per kg. What is the total dosage required?"
Because the three worksheets share the same content in three different formats, you can spread them across the week: one for diagnosis, one for practice, and one for assessment, without repeating a single question.
This set is part of a complete NGSS aligned chemistry unit. The unit also covers Law of Conservation of Mass, Balancing Equations Challenge, Stoichiometry Introduction, Mole Concept Quiz, Mass Mass Calculations, and Mole Mole Problems, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 9-12 chemistry classes, and for NGSS aligned review at any point in the school year. This set is aligned to NGSS standard HS-PS1-7.
