Measuring Nitrate Concentration
Nitrates are important fertilizer for plant growth. Nitrates are also highly soluble. High concentrations can cause problems in surface water if they spur...
Carbon Cycle Chemistry
How does pH data provide evidence of the chemical reactions that cycle carbon through water, air, land, and life forms? In this investigation, students...
Blockly Extension: Fish Tank Water Quality
Students will use an optical dissolved oxygen sensor and Blockly code to write a program that helps...
Blockly Extension: Photosynthesis and Carbon Dioxide Emissions
Students use a carbon dioxide sensor and Blockly code to estimate how many actively photosynthesizing...
Weather in a Terrarium
Students use a weather sensor in a terrarium to understand the relationship between the water cycle and energy within a microclimate.
Water Purification
Students use a pH sensor and a conductivity sensor to evaluate the effectiveness of various water treatment processes.
Water and pH
Students use a pH sensor and a conductivity sensor to investigate how an ecosystem could be susceptible to the effects of pollution.
Transpiration
Students use a pressure sensor to explore how changing atmospheric conditions affect the transpiration rate of a plant.
Soil pH
Students use a pH sensor to investigate how local soil quality may impact the ability to support agricultural crops.
Photosynthesis of Aquatic Plants
Students use an optical dissolved oxygen sensor and a photosynthesis tank to study the photosynthetic rate of aquatic plants under different light conditions.
