Also, block out the barcodes. Those can be used.
Mine had lumps when I shook it.
Thanks, I've just deleted the photo. Mine has a few minor lumps. Not going to open until it's time. I'm worried the cops might show up, in US, they 100% need a warrant I think. I found this experiment online too if anyone needs an excuse if the cops show up, I'm just going to put it on a word doc and print it, and put it right next to the SN just in case.
Evaluating the Effect of Sodium Nitrite on Seed Germination and Plant Growth
Objective: The aim of this science project is to investigate the impact of sodium nitrite on the germination and growth of plants.
Background: Sodium nitrite is a salt with various industrial uses. However, it can also be found in soil due to agricultural practices and industrial waste. Its presence in soil may affect the germination and growth of plants. This experiment will help determine the impact of sodium nitrite on plant development.
Materials:
Sodium nitrite (NaNO₂) powder
Distilled water
Graduated cylinder
Beakers
Seeds (e.g., radish, lettuce, or beans)
Seedling trays or small pots
Potting soil or seed starting mix
Ruler
Gloves, goggles, and lab coat
Procedure:
Put on gloves, goggles, and a lab coat to ensure proper safety.
Prepare sodium nitrite solutions of varying concentrations by dissolving the powder in distilled water. For example, make solutions of 0.1%, 0.5%, 1%, and 2% sodium nitrite. Be sure to label the beakers with their respective concentrations.
Fill seedling trays or small pots with potting soil or seed starting mix.
Plant seeds in the soil according to their specific planting instructions, maintaining a consistent depth and spacing for each seed.
Water the seeds with the prepared sodium nitrite solutions. Label each tray or pot with the corresponding sodium nitrite concentration.
Include a control group that receives only distilled water.
Place the trays or pots in a sunny area or under a grow light, and maintain consistent temperature and humidity conditions.
Monitor the germination process daily and record the number of seeds that germinate in each group.
After germination, measure and record the growth of each plant over the course of 2-3 weeks.
Calculate the average height of plants in each group.
