Our next step involved conducting an experiment that required us to make predictions and to make observations. Our experiment involved mixing a liquid (orange juice, milk, laundry detergent or vinegar) with an antacid tablet. We needed to make predictions as well as detailed and specific observations of our liquid before moving to the next step in our experiment. When it was time to add the antacid table, we were fascinated by the results! We had our timers recording reaction times and thermometers measuring the temperature. It was especially interesting to see the change in pH.
Happy New Year! To kick off our new year, we shared stories on our blogs about something that happened to us over the break. To make our narratives clear and engaging, we needed to organize our ideas into paragraphs, include details to fully explain those ideas and include a sense of voice. Those blog posts came in handy when learning about simple, compound and complex sentences because we used our writing to look for examples of all three. Many of us realized that we tend to stick to simple or compound sentences. Others noticed run-on sentences. We now know what to look for when making revisions, an important part of the writing process! One of our Science curricular competencies involves observing, measuring and recording qualitative and quantitative data. Although that sounds complicated, we actually make these types of observations throughout our day, often without even realizing it. Qualitative data involves using our senses (what we smell, feel, see, hear) whereas quantitative data requires tools (such as a timer, thermometer, ruler, or graduated cylinder) to measure numbers. Using both methods allows us to be specific and precise. To practice, we gathered snow in graduated cylinders and then began recording both kinds of data. Measuring the pH of a liquid is another way to gather quantitative data. pH is a numeric way to measure the acidity or basicity of a substance. We practiced using pH strips by measuring our saliva. We noticed that some of us had a lower than neutral pH and we wondered if that is because we ate fruit at lunchtime (some fruits, such as grapes and blueberries, are acidic, and therefore have low pH).
