My students need an electronic balance to accurately measure small amounts of chemicals in lab.
My students love having the opportunity to learn through engaging experiments, and having access to a high quality digital balance would open up so many opportunities for us to experiment and discover! Please help us reach our potential in learning effectively through useful lab experiments.
Our school is very small, yet innovative and inspiring.
We believe the best way to learn is through hands-on, inquiry-based projects where students can become engaged and the learning happens naturally. We strive for projects that appeal to natural curiosity, which leads to exploration, experimentation, and discovery. There is a lot of emphasis on involvement in the community, so students often engage in projects that actually add value and benefit to the school or neighborhood. There is a warm sense of community that we treasure here. But while we love our little school and take pride in our accomplishments, there is still a lot of room for improvement!
Our science department unfortunately remains lacking in terms of quality lab equipment, which prevents students from being able to properly engage in useful experiments. Many labs require an accurate measurement of mass to produce reliable quantitative data, include those that analyze density, percent composition, conservation of mass, and many more!
Here are some experiments that we would love to conduct with the use of a milligram digital balance:
- Extracting copper from copper solutions to evaluate industrial wastewater management
- Determining the actual amount of aspirin vs. fillers in various brands of aspirin
- Determining the amount of preservatives used in various foods
- Analyzing soil samples for various contaminants
A single, high quality digital balance opens up opportunities for experimentation that 10 low quality balances could not provide.
The reason a 1, 0.1 or 0.01 gram scale would not work is because we often only use small amounts of chemicals, and an inaccurate or low precision reading would result in unreliable data, which would lead to confusing and inaccurate conclusions. For example, a small amount of copper painstakingly extracted from a solution may end up reading as 0 grams. Please help us!
