A few weeks ago I shared Tyler’s science fair project with you. If you want to check it out again click here . This weekend it was Nishe’s turn. We tackled her project. Her items were a little more difficult to find than Tyler’s so it took us a couple of weeks. The last item we need was a thermometer. We finally found one at Walmart. We were thrilled to finally found one. She also got her science fair project idea from sciencebuddies.org. Like Tyler she had a budget of up to $20. After some searching she finally settle on the project plop, plop, fizz fast.
The point of this project was to test the effect of temperature on reaction time on alka seltzer tablets. We used the generic version of alka seltzer. Before we could carry out the experiment we needed the following items:
-Thermometer with a range of 0-60 degrees Celsius
-You can get a thermometer from Amazon.com
– You can also use a kitchen candy thermometer
-Clear drinking glass or jar
-A Graduated cylinder that goes up to 100 mL or you can use a measuring cup
-Hot and cold tap water
-Stopwatch or a clock with a second hand
This project was fun. Nishe’ and I had fun doing it. It was actually fascinating. We filled each of the cups with 250 mL (1 cup) of water. One was hot water, another was cold water, and the last was filled with ice water. We had to put a seltzer tablet in each cup and timed how long it took them to dissolve after we measured the temperature of each one. We did it 4 times. Then we did it once more for the heck of it. I think I might try some other experiments that aren’t mandatory for school because my children seem to love science.
Here are some pictures of the project:
Here is a video of one of the cups. I unfortunately deleted the first video we made so it sounds like I just started off from no where but it’s actually the second video
