Chemistry labs can be incredibly intricate and involve a wide array of measurement devices.  High school students are asked to learn a variety of devices that are often times extremely outdated.  While there is certainly value in showing students how scientists in the past collected data, the reality is we live in a technology advanced world.  Students should be learning how to deal with technology and data entry on computers rather than archaic data collection systems (reading a thermometer, pH paper etc.).  Not to mention the cost to school districts of buying and replenishing these supplies each year.
This leads me to an idea for an all in one chemistry probe. It would take the place of all the measuring devices (particularly for liquids) in a chemistry lab. Instead of having a variety of tools students can use one system for most of their data collection in labs.

This device will be called the ChemAllIn1.  It will be 3-5 inches in length and 1 inch in diameter.  The device will have bluetooth compatibility as well as a wired in option using a USB port that also charges the device.  The device will take measurements common in a chemistry classroom such as: temperature, pH, and conductivity of liquids.  The device will also come with a computer program download where students can read their data in real time, create data tables and export data to excel.  The idea is to create a singular data collection device that creates a simple lab experience for students while still using technology in the classroom.

This is a multipurpose device meant to be used for numerous labs throughout the year in a high school chemistry class.  It will allow students to collect and then manipulate data in whatever way the teacher sees fit.
Possible labs/activities include:
1. Chemical and physical changes lab
2. Properties of ionic and covalent compounds lab
3. Heating and cooling curves
4. Calorimetry labs
5. Acids Vs. Bases Lab
6. Acid/Base Titration Lab
There are also interdisciplinary labs such as testing acidity of rain to understand how solution effects the environment.
