Too hot! Just right! Too cold! Too Big or Too Small Potentially Habitable Exoplanet Astrobiology in Your Classroom 9 9 9 9 What defines life ? What does life look like? Where is life found? What sustains life? Grow Move Breathe Reproduce Feeding Unicellular Multicellular Produce energy Use nutrients Use energy Metabolism Respond to stimuli Adapt/Evolve Displays organization Homeostasis Show heredity Cellular structure What are Extremophiles? Discovery of Arsenic Microbe Where is life found on earth? Let’s Pause for Questions. Activity: It’s Just Right Experiment with gas production of yeast at different temperatures. What will the students learn? The characteristics of life. How temperature is related to the growth and survival of organisms. The concept of life in extreme environments. Materials A Sugar Yeast No water B C D Sugar Sugar Sugar Yeast Yeast Yeast Warm water Warm water Warm water A Sugar Yeast No water Table B Sugar Yeast Warm water Sugar Yeast Warm water C D Sugar Yeast Warm water Table Warm bath Cold bath Graphs and Student Handouts How does this activity relate to “What is life?” Let’s Pause for Questions. Earth or Mars? Is there life on Mars? Where should we look for life? NASA/JPL-Caltech Why Curiosity’s Mission to Mars Matters Artist s Concept. NASAJPL-Caltech Could Mars have supported living microbes? The Rocks Have the Right Recipe Activity: Is it Alive? What will the students learn? How to conduct simulated experiment with soil samples similar to the experiments on the Mars Viking Lander. State relationships between the soil samples using their operational definition of life. How to make an inference about the possibility of life on Mars based on data obtained. Materials A Sand Sugar B C Sand Sand Sugar Sugar Active dry yeast Alka-Seltzer (crushed) Data Sheets Dry Samples Hot water in “A” A Sand Sugar B Sand C Sand Sugar Sugar Active dry yeast Alka-Seltzer Hot Water in “B” A Sand Sugar B Sand Sugar Active dry yeast C Sand Sugar Alka-Seltzer Hot water in “C” A Sand Sugar B Sand C Sand Sugar Sugar Active dry yeast Alka-Seltzer Is it Alive? Physical change, A sugar dissolves. Chemical reaction B after 10 minutes, reaction continued. Immediate chemical C reaction, but stopped after 10 minutes. Other Lesson Ideas Using bottles and balloons Measure balloon’s circumference Do you plan to use these activities in your classroom? It’s Just Right Is it Alive? Both Neither one Let’s Pause for Questions. http://explorerschools.nasa.gov Rudo Kashiri [email protected] Thank you for joining us today. Thanks to today’s presenter!
