Evaluating Water Bottles

We placed 50 mL of vinegar, tap water, seawater into three respective beakers. 50 mL of seltzer water was placed into a jar with a lid

Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel, which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric measurements were the basis of the 3rd part of the experiment. It was displayed during this experiment that a pipet holds about 4mL and that there are approximately 27 drops/mL from a short stem pipet. Part 4 introduced the student to measuring

For the conservation of liquid task both Jacqueline Tyler had very similar answers. They both agreed that the cups of water are the exact same however, Jacqueline said they looked to be the same height while Tyler said they just look alike. Jacqueline did use her higher operational thinking to be able to recognize that they are the same height. Tyler used his guessing skills to be able to notice that they are most likely the same. On the second portion of the problem they both stated that the water amount does not change because you change the cup

Test 1: Water from one standard beaker is poured into the taller and narrower beaker and the child is asked to determine if the beakers have the same amount of water.

1. (15pts) What could have been the students’ hypothesis? (Include specifics on what we discussed in class regarding a scientific hypothesis.)

Our part of the Piaget Project was the Conservation I. Conservation I includes the tasks with the flasks of water, pennies, and different lengths of pencils. With the water flasks experiment, we sat two flasks in front of the kids with the same amount of water. We then asked them if they had the same amount of water or if one had more. They would answer what they thought and I would tip one of them over, and ask them the same question. Their response would show whether or not they had the knowledge of the concept of conservation.

Bottled water is starting to take off in the drinking industry and is looking to outsell soda. Bottled water has spent millions of dollars on their advertisements which is more less than soda.In 2017 water is on track to outsell soda. Industries have been debating if water bottles should be used or not.There are many pros and cons to using water bottles.These 3 articles are showing different perspectives on whether plastic water bottles should or should not be used in our society.Allow me to elaborate.

If it is chosen in this experiment to do this experiment with a smaller bottle of

For my project, I tested which ratio of baking soda and Vinegar would result in the greatest reaction. I also wanted to see if the having more baking soda or vinegar would result in the greatest reaction. My experiments original design was to use a film canister and put baking soda on the lid and the vinegar in the actual canister. Then I would put the vinegar in the canister and clasp it on the lid with the baking soda. Then the canister would launch up because of the reaction. This did not happen as it was supposed to because the vinegar spilled everywhere when I tried to secure it to the lid with the baking soda. I also had trouble because the canister kept falling over and the vinegar and baking soda would spill on the ground. Then I tried using a test tube

Next, I pour water from one of the glasses into the smaller wider glass. I presented both different glasses to her, and ask if she thinks the same amount of water are in both glasses. First, she respond no, than she quickly responded yes. Then I asked her why she thinks both glasses

We wanted to know where we could find the cleanest snow. We tested this hypothesis by testing the snow pH and making visual observation. We decided to do a science place-based lesson since they were in the mist of their science fair preparations. This lesson allowed us to go out to the local community to collect the samples. We were able to visit the ocean, and several areas around the village. Before we started the experiment, we ask the kids did their families collect snow for drinking water. Many of the students did indicate that they did. We ask them where did they collect the snow, but many couldn’t give me a definite answer. This experiment would help explain why certain areas were better collecting place for drinking water. We did this experiment over several days, so the students were quite invested into what we would find. We did find that the water near some buildings and further out in the ocean had the cleanest snow. We hypothesized this may be so, since these areas are rarely touched by vehicles, such as, snow-machines and 4-wheelers. It was a good way for the students to see where some of their drinking water was coming from and why so many residents chose a particular place. We were happy to hear that this experiment would be featured in the Shaktoolik’s science

1. In class, we discussed environmental issues. Water bottles are an environmental issue. Water bottles take 1,000 years to bio-degrade. U.S. landfills are overflowing with mass amounts of water bottles. Prior to discussing this environmental issue in class, I was unaware of how bad water bottles were for the environment. I have always assumed water bottles are recyclable. According to The Water Project, only "PET" water bottles are recyclable. To help reduce the problem, we should be encouraged strongly to bring reusable bottles around with us. If we bring reusable water bottles around with us, there won't be an overflow of water bottles in landfills, and we won't be contributing to the Earth's pollution. After finding out this environmental issue, I have taken my reusable water bottle around with me. If we all use a reusable water bottle, we will also be cutting on costs for water bottle packages. Saving us money, and helping the environment. This issue effects everyone, and we should ban water bottles.

This news article is describing how or if drinking bottles that contain BPA effect your urinary levels. In a current study of college students they monitored the exposure or BPA. At first they could only drink cold beverages from stainless steel bottles. Then for a week they could only drink cold drinks only from two new research-provided polycarbonate bottles (McGovern, A 406). They took urine samples of the participants to compare it to the urine samples in the NHANES study. To McGovern, who wrote this article does say that not all polycarbonate plastics contain BPA (McGovern, A

They are given several minutes to explore. Students must find a desirable question to research and conduct the experiment based on their observations.

Inquiry based learning or IBL has long been used as a teaching strategy in science, however, this strategy has been either misunderstood or misused by the implementers. First of all, it is often thought of that all laboratory activities and experiments are inquiry based. McComas (1997) defined science pedagogical strategies in an attempt to provide a new foundation for laboratory learning. He made distinctions in the terms; activity (exercise), cookbook activity, deductive laboratory, discovery, discretion, experiment, hands-on, inductive laboratory, laboratory, practical work, openness, simulation and verification activity. These terms do not only provide a basis for discussion among science teachers but as an analytical tool to determine the usefulness and appropriateness of the laboratory activity.
