The other day, we did this activity that helped us to understand how the elements share their electrons thus making them non polar. We were given a worksheet and were told to fill in the blanks and draw the elements and their shared valence electrons. I really liked this activity because it helped me to see how the electrons are shared. I also enjoyed making the pictures and such colorful and fun. Here is a picture of the activity we did.

Conclusion for solubility lab: After completing the experiment, I came to realize that my hypothesis was not correct. My hypothesis was that I believed the solids would dissolve easier because the solids can separate more, as the liquids tend to not mix as well. Actually, neither the liquid nor the solid dissolved easier or quicker than the other. This is the case because it really didn’t matter if it was a solid or a liquid, but it mainly depends on the chemical makeup of each solution. In the experiment we used water as our solvent and different variables as our solutes. In order for us to understand how and why each substance did or did not dissolve we had to find out whether or not water is polar or non polar. Water turns out to be polar and this was vital for us to know because it helps us understand how each substance’s molecules attract to the water molecules and ends up separating thus meaning it dissolves. As we placed each substance into the solvent, we started to see different characteristics and changes that helped us to realize whether or not the solution dissolved or not. The most obvious characteristic that helped us to see that the substance dissolved was the fact that we couldn’t see the substance anymore. Also, another way to see that the solution dissolved was that we could see the color change. This happened because the molecules in the substances attracted to the polar water molecules causing the substances to break apart. During this experiment there could be many possible sources of error. One could be the fact that some of the solutions could be over saturated, causing them to not be able to dissolve. Learning about solubility is important for us to know because it helps us to understand when we go to bake different goods if we were to study for the culinary arts and would also just help you bake in general.

Lab Summary: The purpose of this lab was to help us to understand how to correctly identify if a solution is an acid or a base. We used 6 different solutions as well as one indicator. Our indicator in this case was red cabbage. An indicator is a compound that changes colors in the presence of an acid or a base. When the indicator changed colors, we identified that color so that we could see if it was a base or an acid. In addition, we also used a probe to identify the PH level so we could also identify what it was. Also, in our experiment, the control we used was water. When we added water to our indicator the solution changed to be a blue color and the PH was 6.6 which in conclusion, means it’s an acid. The control helped to show that the red cabbage would change colors when another solution was added. The purpose of this lab, with some difficulties, was not fully met. In the beginning we had problems with some soap actually getting into some of our solutions which caused the indicator to not be correct. We ended up going back and fixing the indicator to a certain extent, but it was not quite what we wanted it to be. So those problems made it hard for us to fully understand how to tell what the correct answer was.
 * Substance/solution: || Color: || Number: || Acid, base, or neutral: ||

 * Vinegar || Pink || 2.89 || Acid ||
 * Lemon Juice || Pink || 2.18 || Acid ||
 * Ammonia || Teal || 8.16 || Base ||
 * Apple Juice || Pink || 3.74 || Acid ||
 * Water || Blue || 6.6 || Acid ||

This is a fotobabble that we did on Newton's laws of motion. This was my first time using Fotababble and it was very easy to use and self explanatory. It allowed me to explain this Marble Race lab that we did. I definitely liked this tool and would use it again for other assignments that may need it.

This is a very exciting and creative tool that was used to explain the life of Sir Isaac Newton. This specific activity, called a Scratch, was very easy to create and understand. I thoroughly enjoyed this tool, and I would definitely use this tool again for other projects and lessons.

Scratch Reflection:

Scratch is an animated program in which you can create your own game or skit for many Purposes. When I used Sratch, I created an educational talk show in which you were able to learn about Sir Isaac Newton. I hope that by watching my Scratch people can learn that there are fun and interesting but yet still educational ways of teaching people through different technology tools. Now that I completed my first Scratch I would love to do more with Scratch and maybe even come up with a game. When I explored the Scratch site and saw the all the different things you can create, the games that people had created really stood out to me. I would love to create a game using Scratch and maybe later, I will.

This is a Link to a Timeline I made concerning the Solar System and how it has been seen throughout the years. I used a tool called Tiki-toki in order to create this timeline. This was my first time using tiki-toki and it allowed me to create what I needed to although it would not allow me to add pictures or get the code to embed it unless I upgraded my account type. I would use it again if I didn't need to add pictures and such, but if those were needed I would need to find a new timeline website. I actually used another timeline website before this one but I was having some problems with that one, so I needed to switch. This timeline shows you how Kepler, Copernicus, Newton, Galileo, Tycho, Ptolemy, and the Greeks all contributed to figuring out how our Solar System works.

This is the Bio Cube that I created about Galileo Galilei. I was able to answer many questions about Galileo and what all he accomplished in his lifetime. I would use this tool again for other assignments and people. It was very easy to navigate through and finish. I used the standard cube, but I think there were other ways in which you could add your own personal touches to the cube and answer your own questions. If we use this tool again I would love to be able to explore the sight and see what all you can create. I would recommend using this to different kids, not only for like a school assignment but maybe even as a cool tool to help them study about people, places, events, and more.
