Lewis and Clark students find their own hidden figures

Lewis and Clark fifth graders learn about mass and density by weighing and measuring items in the STEM classes.

Fifth-grade classes at Lewis and Clark Elementary are doing more and more Science, Technology, Engineering and Math (STEM) activities in the classroom. Many of the classes already completed and/or will complete activities to find the mass, density, buoyancy and volume of matter.

When finding mass, students set up charts, use physical properties to describe their matter, then using a balance scales and measure in grams find the mass of items. There is a lot of math going on, partner cooperation, and maybe a little frustration if items need recalculations. Students are encouraged to persevere to get the projects done.

All in all, students are kept busy doing multi-level thinking and problem solving, and determining conclusions. It is always fun to see a surprised face when they guess one way and find out it’s another. More STEM projects are planned throughout the year and we look forward to them.
