Melting Point of Aspirin
Students use a Wireless Melting Point Apparatus to find the melting point range of a commercial aspirin tablet to assess its purity. Choose either the...
Identify an Unknown with Melting Point
Students use a Wireless Melting Point Apparatus to find the melting point range of an unknown substance...
Enzyme Action (Optical Dissolved Oxygen)
Students use a Wireless Optical Dissolved Oxygen (ODO) sensor and (optional) Photosynthesis Chamber...
Radioactive Decay and Half-Life
Students measure the counts coming from a sample of Ba - 137m with a Geiger counter. They answer questions about radioactive decay and half-life during...
Types of Radiation
Students use a Geiger counter to measure the background radiation to calibrate the measurements of radiation source disks. They measure the count through...
Modeling Absorption of Radiation
Students use a Geiger counter to measure the radiation from a radioactive sample of Sr-90. They use the radiation absorption equation to predict the counts...
Determining the Relationship Between Distance and Radiation Count
Students measure the radiation count rate as a function of distance. They use their measurements...
Blockly Extension: Pressure Monitor
Students use a pressure sensor to determine the maximum pressure a stoppered container can hold and create code to warn users when pressure is approaching...
Blockly Extension: Energy Flow
Students use a temperature sensor and Blockly code to sense temperature change within a system and report the direction of energy flow based on temperature...
Blockly Extension: Types of Bonding
Students design code to determine whether a solid compound is ionic or covalent based on conductivity sensor measurements of aqueous solutions.
