This NGSS standard is looking for an understanding that babies (human, cow, dog, plant, etc.) get characteristics from both mom and dad. This simple sheet gives 4 examples of how a baby might look from the two parents pictured. There are many types of inheritance, from simple dominant or recessive characteristics to incomplete dominance, etc., but for first grade, I think the blending of traits (incomplete dominance) is the most easy for them to understand. Thus, if mom has curly hair and dad has straight hair, the baby might get wavy hair. I think first graders can see that. And a red and white flower make a pink flower. Of course, not all the traits on this page are the blending type, as you can see in the human eyes. The baby got her eyes from dad. I think the kids can get the idea of inheritance with these examples. The students will color first, then observe the pictures, and then label. Teacher notes are included.
