Create a prediction on what will happen during the experiment and why.
Use the following format to write your hypothesis “If…, then…”.
If we increase the temperature of the water, then the rate of evaporation will increase because higher temperature provides more energy to the water molecules, enabling them to move and escape the liquid phase more quickly.
What will be staying constant versus changing in this experiment?
Control
Independent
Dependent
In this experiment, the control variable will be the volume of water used. This means that the amount of water will remain constant throughout the experiment.
The independent variable will be the temperature of the water. This will be manipulated and changed to observe its effect on the rate of evaporation.
The dependent variable will be the rate of evaporation. This will be measured and observed as the temperature of the water is altered.

ANSWER EACH
Control: The control variable in this experiment will be the room temperature or the temperature of the environment where the experiment is conducted. It will remain constant throughout the experiment to provide a baseline for comparison.
Independent: The independent variable in this experiment is the type or concentration of detergent used. It will be changed and manipulated to determine its effect on the cleaning efficacy of the solution.
Dependent: The dependent variable in this experiment will be the cleanliness or the level of stain removal achieved. It will be measured and observed as the different types or concentrations of detergent are tested.
What materials are needed to complete this experiment?
To complete this experiment, the following materials are needed:
1. Water: Sufficient amount to fill the containers or to create the desired conditions for the experiment.
2. Containers: Clear, heat-resistant containers to hold the water and observe the evaporation process.
3. Thermometer: To measure and monitor the temperature of the water.
4. Heat source: A stove, Bunsen burner, or a hot plate to increase the temperature of the water.
5. Stopwatch or timer: To measure the evaporation time.
6. Detergent (if applicable): Depending on the experiment, you may need different types or concentrations of detergents.
7. Measuring tools: Graduated cylinders or measuring cups to accurately measure the amount of water and detergent used.
8. Optional: Tongs or heat-resistant gloves to handle hot objects safely.
9. Safety equipment: Safety goggles and lab apron or appropriate attire to ensure personal safety during the experiment.
Please note that additional materials may be required based on the specific details and variations of the experiment.
Should there be any precautions or safety rules to follow for this
experiment?
Yes, it is important to follow safety precautions and rules when conducting any experiment. Here are some safety guidelines that should be followed for this experiment:
1. Wear appropriate personal protective equipment (PPE) such as safety goggles and a lab apron or clothing that covers your body. This will help protect your eyes and skin from any potential hazards.
2. Handle hot objects (such as heated containers or a heat source) with caution. Use tongs or heat-resistant gloves to avoid burns or injuries.
3. If using a heat source, ensure you are working in a well-ventilated area to prevent the build-up of any gases or fumes.
4. Be careful when measuring and pouring liquids to avoid spills and accidents. Also, be mindful of any slippery surfaces and clean up any spills promptly.
5. Follow the manufacturer's instructions and proper handling procedures for any chemical detergents or additives used in the experiment. Avoid direct contact with the skin and eyes, and work in a well-ventilated area when handling chemicals.
6. Never leave the experiment unattended, especially when using a heat source. Accidents can happen quickly, so it's important to remain present and attentive throughout the experiment.
7. Dispose of all materials properly after completing the experiment. Follow appropriate waste disposal protocols and regulations for any chemicals or materials used.
It is always a good idea to consult with a teacher, supervisor, or someone knowledgeable in laboratory safety before conducting any experiment. They can provide specific safety guidelines based on the experiment and materials involved.
