PRODUCT DESCRIPTION

Breathe in and breathe out. What happens to your chest?

Our lungs are like balloons. As we inhale oxygen, they inflate. As we exhale carbon
dioxide, they deflate. Construct a paper lung and inflate it.

Spot the tiny dots. What do alveoli do as we take in oxygen and breathe out carbon dioxide?

Directions:
1) Cut out square; place printed side up. Fold in half horizontally to crease. Flip over and fold on each diagonal.
2) Collapse into a triangle by pulling the edges of the horizontal fold in along the creases.
3) Fold corners of triangle up to center to make a square.
4) Fold left and right corners of square to center.
5) Fold loose points of triangles down in half.
6) Tuck halved triangles into slots below.
7) Flip over and repeat steps 3-6.
8) Inflate!

Aligned with Next Generation Science Standards (NGSS):
K-LS1-1. Use observations to describe patterns of what plants and animals (including humans) need to survive.
1-LS1-1. Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs.
4-LS1-1. Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.
MS-LS1-3. Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.
HS-LS1-2. Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
HS-LS1-3. Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.
