Investigation #1: Strawberry DNA Extraction
Investigation #2: Stress, Senses & Feedback
How are you adapting to social distancing? If you are like me, social distancing has been increasing my feelings of stress and anxiety. What causes stress? Can we prevent It? We will look at a simplified system of how your body responds to stressful triggers. Little ones will use their engineering brains to design a solution to what causes them or a family-member to worry.
How do our bodies process senses? We will look at an example of my dog, Jovie, in how she detects a stimulus (knock at the door), processes internally and responds with a behavior. Grades 3-8 will explore more into sensory processing. Lastly, how does our body maintain stability? Our high school students will explore Feedback Loops and compare them to our anxiety example. They will design an experiment to determine or feedback loops bring the body back to normal (homeostasis) using their own ideas or a heart rate example.
Investigation #3: Earth Day & Hungry, Hungry Humanoids 4/23
Follow- Up Questions Aligned to NGSS for K-12
3rd - 5th Grade:3-LS4-2: Use evidence to construct an explanation for how the variations in characteristics among individuals of the same species may provide advantages in surviving, finding mates, and reproducing.3-LS4-3: Construct an argument with evidence that in a particular habitat some organisms can survive well, some survive less well, and some cannot survive at all.
Middle School (6th - 8th):MS-LS2-4: Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.MS-LS4-4: Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals’ probability of surviving and reproducing in a specific environment.
High School (9th-12th):HS-LS4-3: Apply concepts of statistics and probability to support explanations that organisms with an advantageous heritable trait tend to increase in proportion to organisms lacking this trait. HS-LS4-4: Construct an explanation based on evidence for how natural selection leads to adaptation of populations.
