Week 10

45 × microscope

This is the portable microscope I used to take photos in the class. It’s powerful and very easy to use. When I zoomed in on my iPhone, the magnification can be greater than 45 ×.

The following are the pictures I took. These are all microgreen seeds, which are the experiment materials I am using for my final project. From the lens of the microscope, I can easily see the texture of the surface of the seeds.

Vates Collard

Cutting Celery

Red Kingdom

Final Project Experiment

  1. Sugar
  2. Salt
  3. Cotton Ovals
  4. Distilled Water
  5. Sterile Plastic Petri Dishes (with transfer pipette)
  6. Vates Collard Seeds
  7. Small Containers

Experiment Design

We aim to see how the salinity and osmosis pressure would affect the germination and the growth of the plant.In this experiment, the microgreen will be watered by saline solution and sugar solution with different concentrations from low to high. On the other hand, the control group will be watered by distilled water. Each dish has ten vates collard seeds and correspondent solution and pipette, and the same amount of solution input every day. The salinity tolerance varies hugely from different kind of plants. I end up using 1.5%(mass fraction) as the highest concentration standard and decreasing the concentration from 1.5% to 1.0% and then to 0.5%.
