Activity #1a Katie Abushanab Ast 191: Section 001

1. In activity #1a we were asked to look at a feature on the surface of Mars, my conjecture about the feature is that it has wave like ripples and looks like vibration has gone through the solid surface almost similar to sand dunes in the dessert.

2. The characteristics that classify the features in image #1 can be drawn from the idea that Mars is a dry planet and the ripples occur because of the possibility of wind and lack of water/ hydration on the planet. Adding to the factor of wind it is a possibility that because of the wind the particles of dust in space form together and make this ripple like feature.

3. In activity #1a we are also asked to modify our conjecture about the Mars feature with image #2 of Saudi Arabia. The image of Saudi Arabia has the same look of the ripples and sand dunes as picture #1. Ultimately I believe that both have the lack of hydration in common and winds causing each to have ripple like features on the surface, also combined with the idea of the dust and sand to form these characteristics. Both Mars and Saudi Arabia have climate and weathering that gives the same type of effect on the surface.

4. Image #2 shows the sand dunes and ripples, what is responsible for creating this is the wind and climate as I said before. The lack of water, dust storms and wind can make this effect on the surface just like in Mars.

5. The classification being the sand dune/ripple like features on Mars because of the wind and the lack of hydration allows me to make a global statement about Mars, that being it is a dry planet with extreme winds, no water and excessive dust and the distance in the photo allows me to conclude that the ripples are similar to those sand dunes in Saudi Arabia.

Activity #1b Katie Abushanab Ast 191: Section 001

1. In activity #1b we are given the scenario of our bathroom lights not turning on, my conjectures as to why this is happening is because 1) the electricity bill was unpaid therefore the company shut off the lights. 2) A fuse could have blown causing a malfunction in the electrical wiring. 3) The bathroom light bulb could have burnt out. 4) The reset/ test button on the outlet was accidently pushed causing it to not turn on.

2. To understand why the lights are out, we had to develop experiments to determine the cause. With the first conjecture being that the bill was unpaid the first step in this experiment would be to use a wireless cell phone and call the electric company to determine if the bill was paid or not, from there you could pay the bill over the phone or use the other conjectures to find the solution to the problem. For the next conjecture you will have to go to the circuit breaker box and look for the switch that is between the on/off positions and if one is found switch it back on. The third experiment for conjecture three would be to simply retrieve and new bulb and switch it out with the previous to tell if it was burnt out. Lastly, the final experiment for the fourth conjecture would be to push the rest/test button and switch on the lights outlets and see if the button just happened to be on. 3. As in all experiments you must have a procedure to test the hypothesizes, to begin our procedure we will start with the simplest experiment which would be the fourth, in slimily pushing the reset/test button on the outlets to determine if the bathrooms outlet was temporarily turned off. Next we will move on the first experiment, which would be calling the electricity company and seeing if the bill was unpaid. Thirdly we will move on to the fourth procedure in which we will have to go to the circuit breaker box in the apartment and find if a switch is off, if so we easily turn it to the right direction. Lastly, the third procedure, we have to switch out light bulbs to determine if it was just in need of changing, if so the lights will surely come on with a flick of a switch!
