At the heart of PASCO's Biology through Inquiry lab manual is a commitment to ensuring student learning through all phases of a lab activity. Questions embedded throughout the activity, sequencing and key term challenges, opportunities to predict outcomes prior to data collection and post-lab multiple choice questions all help to make the connection between lectures and labs as seamless as possible.
25 lab activities are included and all of them can be edited to suit the needs of your students or to better coordinate with your classroom lectures.
PASCO probeware means accurate and repeatable real-time data collection. And these activities may be performed using Windows® or Mac® Computers, iPads®, Android® Tablets or ChromeBooks™ with your choice of interface.
Check the Experiments tab for a full rundown on the activities that will be included and stay tuned for more details.
Use a pH sensor to determine which solution is the best buffer.
Use an oxygen gas sensor to understand how optimal environmental conditions, such as temperature, play a key role in enzyme function.
Use a carbon dioxide gas sensor to understand the comparative rates of CO2 gas production for dry, dormant seeds; for wet, germinating seeds at room temperature; and for wet, cold, germinating seeds.
Use a pH sensor to explore the permeability of a cell-like membrane to hydrogen (H+) and hydroxide (OH-) ions. Observe that not all materials are able to pass through the membrane.
Use a pH sensor to determine how effective various substances are at buffering large changes in pH.
Use a barometer/low pressure sensor to explore the concept of cell membranes and how water and other substances pass through a membrane through the process of osmosis.
Use a pH sensor to determine the effect of several gases that cause acid rain on the pH of water. Discuss the effect of changes in the pH of water on
Use a dissolved oxygen sensor to understand the amount of oxygen produced through photosynthesis in an aquatic plant in ambient light, bright
light and darkness.
Use a dissolved oxygen sensor to measure the dissolved oxygen concentration in yeast solutions in the presence and absence of sugar. Calculate the rate of oxygen consumption of yeast during aerobic cellular
respiration at different temperatures.
Use a temperature sensor to measure the change in temperature of water that is heated by burning samples of food and to compare the energy content of those samples.
Use a weather anemometer sensor and current local weather conditions to measure relevant weather conditions at different locations. Determine the impact that a location's environmental conditions have on the microclimate of a given area.
Use a carbon dioxide gas sensor to measure the production of carbon dioxide gas by yeast in aerobic and anaerobic conditions. Determine if high
temperatures effect the respiration of yeast.
Use a weather anemometer sensor, a GPS position sensor, and current local weather conditions to measure relevant weather conditions (such as
temperature, barometric pressure, relative humidity and dew point) at different locations. Students also collect GPS data and transfer the collected data to a computer to visualize how the weather conditions varied on a satellite image.
In this activity, students explore local microclimates by measuring weather data around the school.
Use a pH sensor to understand what kinds of soil in the local community would support agricultural crops, based on pH level.
Use a barometer/low pressure sensor to explore the effects of environmental factors such as air movement on the rate of transpiration.
Use pH and conductivity sensors to analyze the differences in how water pH changes when “acid rain” is added.
Use a pH sensor to understand the effectiveness of various treatments for improving the quality of water.
Use an EKG sensor to measure and observe the electrical activity of the heart muscle.
Use a heart rate sensor to monitor the effect of physical exertion in relation to level of fitness. Determine the average heart rate before, during, and after exercise.
Use a breath rate sensor to measure the resting respiration rates of individuals and determine whether exercise causes a change in respiration rate.
Use a force sensor to determine grip strength and compare muscle fatigue in hand muscles caused by isotonic (“same tension”) and isometric (“same
Use a temperature sensor to understand the extent that external conditions, such as ice water, moving air, or wearing gloves, cause changes in skin temperature.
