Law of Conservation of Mass Activity 5th Grade Science Worksheet
$3.43
This conservation of mass activity helps 5th grade students see that mass stays the same during changes in matter. The station is aligned to NGSS 5-PS1-2 and uses an investigation, a diagram, and a reading passage.
Students explore why frozen lemonade expands while learning that mass is conserved in physical changes. They compare mass and volume, record results, and label scientific diagrams.
The station works well for centers or guided inquiry lessons.
