Students plant a seed and watch it grow.



Planting and watching seeds grow is a wonderful experience for children. A seed is like magic, a seemingly lifeless thing, that can grow into a living plant. Growing seeds can be a very inspirational activity, especially if the children are allowed to watch the seed grow and mature. Watching plants grow will also teach students patience and observational skills.

The requirements for growing a plant is water, nutrients, and sunlight. Too much or too little of these requirements can prevent a plant from growing. This activity has the students looking at the key components of nutrients, so they need to have the soil. In the first grade the students will grow seeds again, but without the soil. In the first grade they will be concentrating on actual mechanism of growth, while kindergarten is focused on all the components.


During this activity the students will prepare the growing environments for their seeds, plant them, water them, and then watch them grow. Prior to this activity you may request from parents any old seeds that they may not have used.

  1. Save milk containers and cut off the tops. Punch small holes at the bottom of the containers. Tell the students that when the seeds grow and the roots get larger, they needs air. Water is important, but too much water sitting in the container can "rot" the roots. The rocks are used to prevent the roots from touching the bottom and getting water soaked. Instruct students to place a few small rocks on the bottom of the milk container, just enough to make one layer. Get a bucket of soil and have the students fill the milk containers 3/4 full of soil.
  2. Place the seed about 1 centimeter into the soil. This will vary depending on the type of seed (refer to the package the seeds came in). When the students water their seeds, first have them use a spray bottle to water, so that they make the "home" for the seed ready because pouring water will unsettle the seed. They can start to pour water, when the seed starts to root.
  3. Move the seed to a warm area, but not into direct sunlight. Again this will depend on the seeds. The seed provides food for the plant until the leaves are formed, which will then let the plant produce its own food. We recommend that you read the directions to the students so they understand that you must do this for each package of seeds you get.
  4. Be careful that the students do not over water their seeds. It is OK for the soil to dry a little, a soaking wet soil is not the best environment.
