East Campus Students Explore STEM Hands-On

Posnack East uses Lego Education to provide engaging, hands-on experiences to explore core STEM concepts. Kindergarten students are learning the basics of Lego building so they develop an understanding of how parts work together to create a whole. This knowledge will be the platform they use as they progress through our Lego Education program that continues until 5th grade. Our Kindergarten students have already created Lego models of a flower, boat, space shuttle, bird, worm, and even a workable cookie jar.
Lego Education continues in 1st grade using their prior knowledge, creativity, and critical thinking skills. First Grade students have been building a workable sailboat while exploring concepts such as wind energy, force, and stability.
Lego education continues in 2nd Grade as they develop an understanding of simple machines. Second grade has been working on building a simple machine that can spin a dreidel.
Rain or Shine, third graders are learning about weather and the water cycle! We are exploring weather tools, weather maps, weather fronts, and predicting the weather. Once we learned about common weather tools, students built their own workable Lego wind vain. Students used their knowledge of colliding weather fronts to create a Lego model that demonstrated what can occur when cool and warm fronts collide. Using their knowledge of the water cycle, students built Lego models to display how humidity effects climate.
Fourth Grade is learning about plants and plant processes. Using compound light microscopes, our 4th graders observed various plant parts. After learning about photosynthesis, students created a Lego model to demonstrate how plants take in water and carbon dioxide and provide us with sugar and oxygen.
Fourth Grade also got to go fishing without even leaving the Science room (or hurting a fish!). Students used their knowledge of pulleys and levers to create a workable fishing pole. With a magnet attached to their fishing lure, they tried to catch as many magnetic fish as they could.
Fifth grade is learning about themselves (well, the human body that is). We started off discussing what makes them so unique (their DNA) and afterward, they extracted DNA from their own cheek cells from a series of chemical reactions. Next, we discussed how the brain and nervous system control our bodily functions. We got a “closer” look at the brain by dissecting one (a sheep’s brain).
The simplest weighing machine is a beam balance. The original form of a balance consisted of a beam with a fulcrum at its center. A change of weight on either side of the balance will change the beams positioning and affect the balance achieved. Fifth graders were challenged to build a model Lego balance and investigate how it functions.
