Quantifying biological processes can be challenging, but with PASCO’S sensors and SPARKvue software, it’s easy to collect reliable data. And using PASCO for biology makes it easy to study topics such as photosynthesis, cellular respiration, enzymatic reactions, diffusion and osmosis, human physiology and more!
Intuitive software SPARKvue software is designed for science inquiry and delivers an incredibly intuitive user experience. It is data collection and visualization made easy.
Wireless Sensors Our innovative and low-cost wireless sensors allow you to connect directly to your devices via Bluetooth®.
Standard-based labs Designed by teachers, for teachers we have standard-based experiments for Biology courses including advanced AP.
Transpiration is an important concept in both biology and environmental science, especially in terms of role it plays in the water cycle. As water evaporates from the stoma of leaves water is pulled up (due to hydrogen bonding) through the xylem from the roots which have drawn the water from the surrounding soil.
Because transpiration is essentially an invisible process, a potometer is used to measure the rate of water lost to the air. The advantages that sensor technology makes in many investigations in biology and environmental science are that it allows students to see the data in real time while great improving the accuracy and significantly decreasing the time needed to capture data.
