 Questions from Lab How the phases of the moon occur? - The phases of the moon are based off the placement of the sun and how much of the moon is covered by it.  What causes the seasons? - The season are caused by where the earth is and how close it is to the sun as it rotates throughout the year I think? What causes a Lunar Eclipse?   - I am not sure what a lunar eclipse is, but maybe it is based on a change in temperature?  Questions for Blog 1. What did you do in lab today? - In lab this week we learned all about the moon, sun, and the earth. Somethings we focused on were, what causes a lunar eclipse, what causes the seasons, and how certain phases of the moon occur. It was really helpful to use the bright light, the globe, and the styrofoam ball as a model because it demonstrated the science behind those questions right infant of our eyes.   2. What was the big question? - How do the sun,  earth, and moon all impact one another?...

  The big question addressed in lab, and a description of what you did. In lab this week we discussed, "How to create a safe and durable playground surface?" In order to model this, we used eggs to represent children and different materials that could be used for playground surfaces. Our group Used mostly straw, rubber pieces, and sand. At first our playground surface was too bouncy. Our egg was bouncing like crazy when it made contact. Then we chose to take away some of the rubber and indent the middle so it had a place to fall. This really helped as our egg was able to survive multiple test runs although the egg had some cracks in it. We found that too much rubber can cause injuries to children!  A description of what you learned in Thursday's lecture. This week was exam week! I felt pretty confident going into the exam after putting in time to study and received a B+. This is something I am proud of yet also disappointed in. The grade is not terrible but I know I could...

  The big question addressed in lab, and a description of what you did. This weeks lab we switched focus from slides to swings. The big question was, "What affects how long it takes for a swing to go back and forth?" The variable we chose this week was weight. We tested this by measuring the time it took to swing back and forth one time while adding weight each time. After many tests, we found that the weight does not matter and the time will always be roughly the same.  A description of what you learned in Thursday's lecture. In lecture we investigated, rider weight and the length of rope or chain. We found that the riders weight does not affect the period of a swing. Next we focused on the length of the rope or chain and we found that the longer the rope, the longer the period will be. Bottom line, period does not depend on rider weight, period does depend on the chain or rope length, and a longer swing equals a longer period.  Answer questions about the weekly textbook...

The big question addressed in lab, and a description of what you did. This weeks big question in lab was, "What affects the speed of a rider using a slide?" Our class used meter sticks to create a slide and photo canisters as our riders to test this question. Our variable that we tested was the texture of the clothing of the rider. Tp test this we used, silk, felt, soft burlap, rough cotton, and soft cotton. For this our independent variable was the material, the dependent variable was the speed of the rider, and our controlled variables were slope, rider weight, and distance in meters. We found that the felt made the rider slide down the slide the fastest.  A description of what you learned in Thursday's lecture. We focused on a couple different ideas in lecture this week. The first being height, the second being steepness, the third being surface/clothing, and rider weight. These are the different variables we tested through in lab but now we were Abel to learn abut all...
