Virtual Laboratory and Field Study Guidelines
Our goal is to provide you with as many effective, rich laboratory experiences as possible. Sometimes this means that virtual options and field options are part of our courses, allowing you to use apparatuses that are too expensive or dangerous, or getting you to focus on the environment near you.
Labs where the materials are not in front of you require a different approach than more traditional lab activities.
Some labs may be truly virtual labs, while others may be field studies that require a computer to analyze data. In all cases, when you do a lab, think about the various settings that the lab might be done in and ask yourself if you feel that you could complete the lab in that setting. For example, if you are using a virtual microscope, be sure that you are also thinking about how a real microscope would look, feel, and work.
Virtual experiences will not be exactly like real experiences in the lab. Pay strict attention to the safety considerations that you would think about if it were a real lab. When doing field studies, take precautions in assessing your local environment, which may have wild animals and poisonous plants, bad weather, or other dangers that are a natural part of the area you are studying.
We have worked hard to see to it that virtual data are as much like actual data as possible. In most cases, the data that you record and analyze will not be the same as someone else's and will be subject to the uncertainty and error that you would find in a similar real-life lab. Keep these ideas in mind as you work on virtual labs and field studies. You never know when you might be doing a similar procedure in a different setting.
Safety in the Lab
Scientists understand that conducting experiments involves a certain amount of hazard and risk. They have identified certain safety practices and guidelines that address the hazards and risks involved in laboratory work.
Follow these practices and guidelines and use common sense to ensure your safety in the laboratory.
Lab Setup
• Make sure your lab area has adequate ventilation. When possible, open windows; otherwise, turn the fan switch on the thermostat to the ON position. Set up an electric fan to help ventilate the lab area.
••
Keep drawers and cabinets closed to prevent physical hazards.
Identify a location with easy and immediate access to fresh, running water. This is important for flushing eyes and skin in case of contact with chemicals.
• If you are using an area where food is prepared or consumed, secure all food items in such a way as to avoid contamination.
•.
Keep a fire extinguisher in the lab area and know how to use it.
Post the number to the nearest poison control center near a telephone. You can find this number by calling the national poison control number: 1-800-222-1222.
Personal Protection
• Wear gloves throughout lab preparation, the entire lab procedure, and during cleanup when using
Wear gloves throughout lab preparation, the entire lab procedure, and during cleanup when using ammonia. Always dispose of the used gloves before leaving the lab area.
• Wear clothing you can remove easily in case of an accident. Clothes should cover the body from the neck
•
to at least the knees.
Wear closed-toe and closed-heel shoes. Do not wear high heels, shoes made of woven materials, or sandals in the lab area.
• Tie back long hair and remove jewelry before entering the lab area.

First Aid in Case of Accident
• Refer to the Safety Data Sheets if you inhale or swallow chemicals or if chemicals come into contact with your skin or eyes.
• If you are burned, rinse the area thoroughly with water. Do not apply ointments or other remedies to the burn. Cover the burn with a gauze bandage. If the burn is serious, call for immediate medical help.
• If you are cut, do not rinse with water unless the cut is dirty. Apply a bandage. Seek medical attention if the cut is serious. Have a doctor remove any splinters that are part of the cut.
Lab Protocol
:
If possible, have an adult or peer present while conducting all labs.
•
Never ingest anything in the lab. Eating, drinking, and chewing gum are not allowed.
Do not ingest, taste, touch, or smell any chemicals.
••
Flames are not allowed in the lab area when using flammable gas or liquids.
Keep chemical and solution containers closed until they are needed.

Always check glassware, and discard any with chips, breaks, or cracks in a safe manner.
Clean up broken glassware as soon as it is safe to do so, and discard in a safe manner.
• Clean glassware before returning it to storage..
•
•
Always wash your hands thoroughly with soap and water after cleanup and before eating or drinking.
Clean up spills immediately.
•
•
Always discard used and spilled chemicals and solutions down the drain, diluted with plenty of water.
K12 instructs you to dispose of chemicals in the same safe manner that you would dispose of any excess household cleaner, paint, or motor oil. One environmentally friendly disposal alternative, offered in many areas, is a household waste disposal event. These events are held periodically by the local waste disposal agency and offer a safe method of disposing of household chemicals, such as the chemicals used in K12 lessons. We recommend you contact your local agency for the availability, schedule, and location of any events in your area.
General Procedures
Follow these General Procedures each time you conduct an experiment. They will help you develop good lab practices
Setting Up and Maintaining Your Lab Area
• Read through the entire procedure before beginning any lab.
• Review the list of materials prior to any lab because you may need to supply several items. Gather all
•
materials in your lab area before beginning any lab.
Set up a lab area where you can organize your materials and have room to set up your lab. (For most labs, a countertop or table will work well.)
• Always keep a copy of the Laboratory Guidelines in your lab area. Follow all procedures for Lab Setup in the Safety in the Lab section of these guidelines.
•.
When using measuring utensils in several steps, wash and dry the utensils between steps.
If you do not complete a lab, store all materials out of the reach of small children or pets until you are ready to complete the lab. Notify everyone in the home that you are conducting an experiment and tell them not to touch it.
Cleaning Up Your Lab Area
Clean up and properly store materials after each lab. (Materials and equipment are reused in labs.) Thoroughly clean your hands, as well as surfaces, containers, and like items, with soap and water.
Taking Good Measurements
Thoroughly dry materials before storing them. Taking Good Measurements
Take careful measurements during a lab, and repeat tests until you are confident about your results. If you think there is an error (for example, you may not be certain you started the stopwatch at the right time or you think you miscounted the time), do the procedure again.
• Length: Measure in centimeters (cm) or tenths of a centimeter, depending on the detail you are able to observe.
Time: Measure in seconds (s) or minutes (min).
Mass: Measure in grams (g).
Force: Measure in newtons (N).
Calibrating a Spring Scale
:
Adjust the screw at the top of the spring scale so that it reads zero (0) when nothing is hanging on it.
Hold the spring scale by the closed metal loop and hang an object off the hook using a rubber band or a piece of tape.
Recording Data
Use a data table to record your data. Make sure your data tables are prepared before you do the lab. You may use scratch paper to record your data during the lab, and then transfer your data to a computer for a final report.
Plotting Data
Plot the independent variable on the x-axis (horizontal) and the dependent variable on the y-axis (vertical)..
Bounce height
Drop height
Drawing Trend Lines
Use trend lines to show the general relationship between the independent and dependent variables. Trend lines may be straight or show a curve, but they are not an attempt to connect every point on a graph.
Based on the information provided from the "Virtual Laboratory and Field Study Guidelines," here's a comprehensive lab report template. If you could specify the actual experiment details, I can fill in the blanks, but for now, I will create a generic example. You can replace the placeholder information with specific data related to your experiment.
Lab Report: Physical Properties
Introduction
The purpose of this experiment is to investigate the physical properties of various materials and understand how these properties can be measured and compared. This experiment focuses on concepts such as density, mass, and volume. Our hypothesis is that denser materials will sink in a fluid while less dense materials will float.
Experimental Methods
Materials
- Virtual Laboratory Software
- Beakers (virtual)
- Electronic Balance (virtual)
- Graduated Cylinder (virtual)
- Water (virtual)
- Various solid materials (e.g., plastic, metal, wood - all virtual)
Procedure
- Start the virtual laboratory software and select the "Physical Properties" module.
- Choose a variety of solid materials to test (e.g., plastic, metal, wood).
- Measure the mass of each material using the electronic balance. Record the mass in grams (g).
- Measure the volume of water in the graduated cylinder. Note the initial volume.
- Submerge each solid material in the water and record the new water level. Calculate the volume of the solid by subtracting the initial volume of water from the final water volume.
- Use the formula for density (Density = Mass/Volume) to calculate the density of each material.
- Repeat the measurements for accuracy and record any observations made during the experiment.
Data and Observations
The following table summarizes the data collected during the experiment:
| Material | Mass (g) | Initial Volume (mL) | Final Volume (mL) | Volume of Solid (mL) | Density (g/mL) |
|-----------|----------|----------------------|--------------------|----------------------|-----------------|
| Plastic | 50 | 100 | 105 | 5 | 10 |
| Metal | 200 | 100 | 110 | 10 | 20 |
| Wood | 30 | 100 | 102 | 2 | 15 |
Additional Observations
- The plastic material floated on the surface while the metal sunk to the bottom.
- The wood partially submerged, indicating its density was less than water but higher than the plastic.
Conclusion
Based on the results of this experiment, we can conclude that denser materials such as metal sink while less dense materials such as plastic float. The data supports this conclusion, as seen in the measurements collected (e.g., the metal had the highest density of 20 g/mL, while plastic had a density of 10 g/mL).
In evaluating the experimental design, the use of virtual tools provided a safe and efficient way to explore physical properties without the hazards present in an actual laboratory setting. However, a potential improvement could include the use of real-world comparisons to validate the virtual data against physical samples.
To enhance future experiments, I propose increasing the variety of materials tested, including more organic materials to observe a broader range of densities.
