In Minnesota we can't always wait for the weather to provide optimum growing conditions. Why not start something growing inside today?
Grass - grass seeds take root and grow quickly. You may have seen grass coming from an egg shell or potato like hair from your head. Those are whimsical, simple and fun to do. But you can also grow a larger patch of grass in a basket or deep dish. What's fun about the larger container is you can grow more than one variety of grass and see their progress. Once the grass was really established we'd get out our scissors and give the grass a trim. Each child had their own basket of grass. We took photos of our grass garden, propped small plastic items in our grass garden and later when the weather was warm our garden came outside to continue growing. You'll need grass seed - several varieties if you want to go that route - good potting soil, a container that can be lined, drainage of rocks and gravel. If you want to use a pot made for plants you don't need the drainage items.
Terrarium - these clear container gardens are wonderful for indoor enjoyment. A variety of plants do well in these containers including succulents. You'll need the container - glass or plastic, rocks and gravel for drainage, good quality soil and several plants. Don't overcrowd when planting as each plant needs room. Place in a window so it gets some good light each day and enjoy. We would occasionally put in a toy animal or character which made them look like they were in a jungle. It's interesting to watch not only plant growth but see the roots taking hold. Placing a lid or plastic cover over the container will do a variety of things including raising the temperature in the space and providing "rain" inside the terrarium. The lid or cover should be removed as plants grow larger and to allow for air flow to the plants.
Using a lunch size bag is easiest for small children to manage but you can also scale this up to a grocery sized bag. Have the children decorate their bags with stickers, markers, crayons, etc. Punch holes in all four corners of the open side of the bag, tie a length of light weight string to each corner through the hole (you may want strengthen the corner of the bag before punching the hole by using a piece of tape on the inside and outside of the corner), gather all four lengths of string from the corners and tie together. As the child runs the bag fills with air and flies. You can tie the four corner strings to a another string so that the child can have it trail after them. Light weight streamers can be added - crepe paper or light ribbon works best. This kite flies well outdoors too!
Jumping for Joy
How about a bubble wrap hopscotch game? Doesn't that sound fun and exciting? We made bubble wrap spaces for hopscotch and then using gentle painter's tape secured them to the floor. They actually worked well on carpeted floors or over rugs as well. No matter the person's skill level at hopscotch everyone got a lot out of jumping on the bubble wrap. It's a sensory and physical release that satisfies the longing for the days spent out in the spring sun . . . at least for a little while. Great for rainy days or anytime!
