Testing seeds for our garden
Today we had Life Science at Mommy School. We found a box of old seeds. Some of the seeds were a decade old. A decade is ten years. We tested the seeds to see if they were viable (vi-a-ble). Viable means the seed is still alive and can grow. We used paper towels, water, and a glass to test the seeds.
The seeds we tested were Dill, Catnip, Basil, Tomato, Cilantro. Cilantro is also called Chinese Parsley. Mom uses Dill to make pickles. We pick Basil from our garden to make spaghetti sauce! My kitties love Catnip. Catnip is a member of the Mint family. Mom uses mint to make our toothpaste and lemonade when we have picnics!
We poured a glass of water. We counted the seeds. We poured the seeds into the glass. If the seeds floated they were not viable and we could not plant them. If the seeds sunk to the bottom of the glass we could add them to seed tape and plant them. Seed tape is made with paper and seeds and water. When they are planted they will sprout and grow. Sprouting means the seed will make green stems called a shoot. The shoot grows up through the dirt and finds the sun! The shoot will grow lots of leaves to use the sunshine to make more leaves and grow really big! The leaves use sunlight with photosynthesis (pho-to-syn-the-sis).
Our first seeds all floated so we did not use them. We will have to get more Tomato, Cilantro, and Dill. Basil seeds are very small. Dill seeds are very big. Half of our basil seeds floated and half of them sank to the bottom of the glass. I knew I could plant the seeds that sank to the bottom of the glass! We scooped the seeds from the bottom of the glass and put them on a piece of paper. We poured water on the paper. We rolled the seeds up in the paper so they would not get away. Then we put a shoe box with dirt and Epsom salt and sugar in the sun and put the seed tape in the dirt and covered them up. We had three seed tapes we could use. The rest of the seeds would not grow.
This experiment for Life Science was useful because we learned how plants sprout and how to test if seeds we buy are still viable. We also played in the dirt which was fun too! We will finish this experiment in one week. My brother and I counted the seeds on the tape and we will count how many of the seeds will sprout. It will take between three and seven days before we will know how many of our seeds will turn into plants!
