1. LIVE INTERACTIVE LEARNING @ YOUR DESKTOP November 30, 2011 NES: Properties of Living Things: Searching for Life on Mars Presented by: Marti Phipps

2. Properties Of Living Things: Searching For Life On Mars Presented by Marti Phipps

3. Introduction Use personal definition of life to determine if life exists in three soil samples. Make observations and illustrate findings

4. National Standards Science as Inquiry Chemical Reactions Structure and Function in Living Systems Cells and Biological Evolution Earth’s History

5. Objectives Students will: Form an operational definition of life. Conduct simulated experiment with soil samples similar to the experiments on the Mars Viking Lander.

6. Objectives Students will: State relationships between the soil samples using their operational definition of life. Make an inference about the possibility of life on Mars based on data obtained.

15. Review What three types of spacecraft have gone to Mars? Can you name an Orbiter? Lander? Rover?

16. Let’s pause for questions from the audience.

17. Living?

18. Conditions Water Energy – Chemical – Geothermal

19. Conditions Water Energy – Chemical – Geothermal Bio-signatures – Carbon

20. Is it Alive?

21. Discussion Questions What are some characteristics of living things? What are some characteristics of nonliving things? How are living things different from nonliving things?

22. Fundamental Criteria for Life Chart Criteria:

23. Criteria: React to its environment? Criteria: Fundamental Criteria for Life Chart

29. Let’s pause for questions from the audience.

30. Materials Sand or sandy soil sample 3 glass vials (baby food jars or beakers for soil samples) Sugar – 5ml will be added to soil Instant active dry yeast – 5ml will be added to 50 ml of soil Alka-Seltzer tablets crushed – 1 tablet will be added to 50 ml of soil

31. More about Materials Hot water – enough to cover the top of the soil in all jars In regards to the hot water, make sure it is not hot enough to kill the yeast! Cups for distributing the water Enough magnifying lens so that each group can have at least one or more Copy of the student recording sheets

32. It’s Alive Students will take three different soil samples and look for signs of life based on their criteria.

33. Data Charts

34. Procedures Jar 1: Fill with 50 mL soil Add 5 mL sugar

35. Procedures Jar 2: Fill with 50 mL soil Add 5 mL instant active dry yeast and 5 mL sugar

36. Procedures Jar 3: Fill with 50 mL soil Add 5 mL sugar Add the powdered Alka-Seltzer
