In class today we learned about acids and did an acid testing lab. We found that when you slowly squirt 5ml of vinegar into a cup with 1ml of baking soda, a reaction happens which causes bubbles. When the same experiment is tried in a bottle that has an air tight stopper, we saw the syringe raise up due to carbon dioxide gas rising. It was really interesting to see the syringe move all the way out becuase of the reaction that was caused by the vinegar and baking soda. I learned today in class that baking soda is an indicator of the presence of acid. That is why vinegar reacted and let off carbon dioxide gas. Because baking soda is an indicator we used it to mix with different fruit juices to see how acidic they were. We found that lime was the most acidic of lemon, orange, and grapefruit juice. All four juices bubbled a bit, but lime was by far the juice that reacted most.

During class today we went to a different classroom that gave us access to technology and we used an interactive website to learn about nutrition. This website was very colorful, interactive, and useful. It would be a great site to use with students while teaching a lesson about health or calories. The internet is full of great websites like this one in order to get students engaged in science and do a hands on activity. I think science is a content area that is learned effectively with hands on experiments. Using technology is a great hands on tool to keep children interested and engaged in the information they are learning.

In class today we discussed chapter 2 of Ready, Set, Science. This chapter discusses the four strands of science. 1) Understanding scientific explanation, 2) Generating scientific evidence, 3) Reflecting on scientific knowledge, and 4) Participating productively in science. These four strands are the skills we hope our students eventually acquire. I learned that in order to be proficient, we need to view science as a body of knowledge as wells as an evidence based enterprise.
In class we also discussed classroom and lab safety. We made a Safety Game Activity that would be fun to play with students in the first week or two of school to help them learn all of the safety rules while in the classroom.

We were introduced to the Ready, Set, Science text. We were given a lot of information on the reason science is so important. It can be the foundation for language, logic, and problem solving skills. Science is also extremely important to help us as citizens understand what is going on in our community and world. We also learned about the new vision of science education. We as teachers need to look at our students and realize they could be future scientist. We need to guide them through science instruction and help them understand all of the different strands of science. By helping our students realize science is not just mixing chemicals in a lab, but also about things such as plants, animals, and the human body, we may help them realize they want to be doctors or veterinarians. Science has endless possibilities and when teaching young children, we need to help them see all the things science can offer.

We did the Temperature Probe Response Time experiment. Within our groups of 4, we used the Easy Temp Probe and the TI-84 graphing calculator to test the amount of time it took for the probe to reach it's maximum heat when being placed in ice cold water then hot water. After placing the probe in ice water for 20 seconds, then moving it to hot water, the temperature jumped from 45.3 degrees Fahrenheit to 94 degrees Fahrenheit. We found that the relapse time (the time it took to reach max heat which was 94 degrees) was 29 seconds.
This lab was a great lab because the directions were pretty easy to follow and it required us to work with technology as well. The TI-84 graphing calculator graphed a chart of what our temp X time looked like. Our graph shot up right away and then leveled off at the 94 degrees.
