ENGAGE, Part 1 Name _____________________________ Handout Date ___________________________ Cartesian Diver Observe the “diver” as the teacher demonstrates it. Record any observations you make about the “diver” in the space provided. Make a sketch of your observations. Observations of “diver:” ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 
Explain how the “diver” works. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ENGAGE, Part 1 Name ___________________________________ Handout Date ____________________________________ Making a Cartesian Diver Purpose: To simulate descending in the ocean. Materials: 2-liter bottle 3-medicine droppers small beaker water
Procedure: Place a small amount of water in the small beaker to fill the medicine droppers. Fill the first dropper ¾ full of water. Fill the second dropper ½ full of water. Fill the third dropper ¼ full of water. Next, fill the 2-liter bottle with water. Leave a small amount of space in the neck open with air to put in the droppers. Place each dropper in the 2-liter bottle. Fill the 2-liter bottle so that no more air exists in the bottle. Cap the bottle. Draw the Cartesian Diver in the data section. Note the location of each dropper (label each dropper). Squeeze the 2-liter bottle with your hands. Record your observations in the data section. Attempt to squeeze the bottle until all droppers touch the bottom. Record which dropper hit last. Data: Drawings:
Analysis: Why did the droppers float in the 2-liter bottle initially? What happened to the water level in the droppers when pressure was applied to the 2-liter bottle? What happened to the density of the droppers after they took on more water? How do divers use this concept to ascend and descend in the water? How does the Cartesian Diver simulate the technology used in a submarine to allow it to ascend and descend in the water? ENGAGE, Part 1 Name ___________________________________ Handout Date ____________________________________ Making a Cartesian Diver Purpose: To make and observe a Cartesian diver. 
Procedure: List the steps below for making and testing your “diver.” ________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________ Drawing: Make a sketch of your “diver.” Observations: Conclusion: What did you do to get your “diver” to sink and float? ______________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Why does this cause the “diver” to sink and float in your tank? ______________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ How do divers use this concept to ascend and descend in the water? ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ How does the Cartesian Diver simulate the technology used in a submarine to allow it to ascend and descend in the water? ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ EXPLORE, Part 1 Name ___________________________________ Handout Date ____________________________________ Part 1: How do we explore the oceans?
