Bottle-Flipping Experiment
This experiment started with an argument in class about the optimal amount of water in a bottle for flipping. Should it be 1/4 filled; 1/3 filled; Just below 1/2? We decided that we would have to try it, so we designed an experiment. We considered variations like skill of tosser, variations in bottles, height of the tosser, etc. We started with 32 bottles filled to various levels. We flipped a total of 4,220 times. Here is a graph of our data.

9. Explain your scientific argument about how much water is best for bottle flipping.
10. Study the graph. About how much water led to the most successful bottle flips? 11. Are bottle flips most successful with more that half full or less than half full. how do you know? |
Taxonomy Review

Crayfish, crawfish, crawdads, or mudbugs may be an animal you recall studying in 3rd grade. They are decapods (have 10 legs) and are related to lobster and shrimp. There are over 400 species of crayfish. Watch this short video. |

Largest Species of Crayfish: Tasmanian Giant Freshwater Crayfish |
Smallest Species of Crayfish: Eastern Swamp Crayfish |

Weather Review
22. Draw a model of the water cycle that differs, somewhat, from the one above. Use this caption to label your model.
The sun. Heat from the sun warms the earth, and causes liquid water to evaporate. As it evaporates, we may notice it in the air as humidity. High in the troposphere, where it is cooler, water vapor (gas) condenses on particles of dust and becomes clouds. The earth is in constant motion and is unevenly heated, so the clouds move from place to place. At some point, the clouds will release their water as precipitation - which could be rain, sleet, snow, or hail, depending on other atmospheric conditions. That water falls, runs-off, collects, and evaporates again continuing the cycle.
23. Why is the water cycle important to weather?
24. Explain what drives the water cycle?

On SCPASS you will see a variety of charts and graphs. The first things to do with a new chart of graph is to study it. 25. What are 3 things you notice about this graph? 26. This graph does not have a title - what should the title be? 27. This graph has all 4 sides labeled and numbered - why?28. 28. Which layer of the atmosphere is closest to the earth? 29. What happens to the temperature as we rise higher into the troposphere? 30. What happens the temperature between 10 and 20km of altitude? 31. What happens as we rise higher into the stratosphere? 32. What happens as we rise higher into the mesosphere? 33. Which atmospheric layer has the lowest temperature at any altitude? |
Energy Review
34. Without looking it up, what is energy?
35. How are batteries related to energy?
36. What's the difference between an electromagnet and a permanent magnet?

Your teacher may give you a battery, a nail, some wire, and some paperclips. Arrange your items as shown in the picture.
A. Does the electromagnet pick up paperclips if you remove the battery from the circuit? B. Do both ends of the nail pick up paperclips? C. If you increase the number of coils around the nail, what happens to the number of paperclips it picks up? D. If possible, join with a friend to make an electromagnet with 2 batteries. How do more batteries impact the number of paperclips it will attract? Once you have answered the questions, please follow your teacher's instructions on how to disassemble your materials and put them away. |

Animals (and graphs)
|
Study the graph. The statements below are false. Rewrite each false statement as a true statement.
41. The mouse is cold-blooded (ectothermic) and maintains its body temperature regardless of the environmental temperature. 42. The lizard is cold-blooded (exothermic) amphibian. 43. As the environmental temperature increased, the lizard's body temperature decreased. 44. When the environmental temperature was 10 degrees C, the mouse's body temperature was about 25 degrees and lizard about 10 degrees. 45. If we were to graph a human, it's graph would resemble that of the lizard because both are ectothermic. |
Teacher, please talk through this graph with students. What do they notice? What do they wonder?
- What do Joules measure? Energy
- What happens to the energy of each animal as the temperature increases?
- At what temperature does the mouse begin to have energy?
- What happens to the mouse's energy as the temperature rise above 40 degrees?
7. Plant Responses
Phototropism is the directional growth of an organism in response to light.
Thigmotropism describes plant growth in response to touch or contact with a solid object.
Gravitropism is growth in response to gravity. Gravitropism is very important in plants as it directs root growth toward the pull of gravity (positive gravitropism) and stem growth in the opposite direction (negative gravitropism).
