Spring | Soil: Grades 1-3

What Works Best: Experimenting with Different Growing Mediums

Summary: Soil comes in all types: sandy, rocky, clay, wet, dry, hot, and everything in between. Gardeners will have the opportunity to explore the properties of soil by running their own soil experiment. Gardeners will also have the opportunity to practice writing scientific observations and following the scientific method.

Pre-Visit Planning: 

In the Garden: 

Plants are an essential part of our ecosystem. Just like we need the proper nutrients to live and be healthy, so do plants. Look at your containers of soil types: sandy, rocky, clay. Explore what they look and feel like. 


-What do you notice about each soil type? How are they similar? How are the different? 

-Describe each soil type by creating a four square chart in your gardening notebook. In your chart write down a few adjectives about the way each soil looks and feels.

-Take some time to hypothesize what soil type will make our plants the most happy. Use your observations to form a hypothesis, your guess about what you think will happen, that you will later test.

Questions to Explore:

-What do you think a seed needs to grow?

-Describe a handful of garden soil.

-What do the other types of soil feel and look like?

-Would you use the different materials for different uses? If so, what?

-Which type of soil will the seeds like the most?


  • Take some loam (soft, healthy dirt) from the garden and place it in a new plastic cup or container. 
  • Place one seed in each plastic container and mark on the outside of the container where in the soil the seed is. 
  • Over the next few weeks, keep the seed consistently watered and track the seed’s growth. 
  • Write your growth observations in a new four-square chart each day. What do you notice? Which soil did the seeds like the best?
  • When at least one seed has grown to the surface of the soil, write a summary about your findings. Which soil did the seeds grow well in? Was your guess, or hypothesis, about the best soil correct? 
  • Now, take your cup back to the garden, and plant your seedling into a bed with other plants.

Beyond the Garden | Soil Analysis Around the Neighborhood

As you wait for your plants to grow, take some time to explore other kinds of soil around your neighborhood. Look at a garden in a park near your home. Look for places where plants are growing. When you find one, stick your finger into the soil. What does this soil feel like? Do the plants seem to grow well here? Use this information to help you make more observations in your garden journal about the kinds of soil plants prefer to grow in.

To take your exploration even further, you can begin to test your soil’s pH level and find out how acidic or alkaline it is using one of these methods: http://www.wikihow.com/Test-Soil-pH

Note for Parents:
Each lesson suggests you explore a piece of artwork and read a specific book with your child. The artwork and books are easily available for view with an online search. However, these suggestions are not necessary to complete the lessons.

Guiding Principles


Learning, though not always visible, is always happening. The lessons are designed using inquiry as a base. Rather than “right answers” be more concerned with asking good questions.


Things may not go as planned. The lessons are designed to be used in whatever way works best for you. You can use all of the lesson or just pull a piece out of it.


Planting and cultivating a garden is believing in possibility. The lessons are designed to generate excitement about the future.


Each lesson includes a way to take the learning out into the community for more learning and more connection.


When a young child’s innate curiosity is unleashed in a garden the possibilities are endless. Any topic is open for exploration.


You will get dirty. There will be bugs.
