You can also explore how fast different seeds germinate by comparing different kinds of seeds under the same conditions. We tried sunflower seeds, peas, and beans in our seed jar.
Pea seeds grew rapidly once the root popped out and grew the tallest.
STEP 1: Fill the jar with paper towels. Kids can fold them and push them down into the jar. This is also great work for little hands.

Watching seeds grow is an amazing science lesson for kids. Our seed germination experiment gives kids the opportunity to see up close how a seed grows what would actually be happening under the ground! Our awesome seed growing activity turned out amazingly well, and we loved checking on the progress each day! Simple science activities are great for young learners!
Or keep the type of seed the same and set up two mason jars to explore whether seeds need light to germinate. Place one jar where it will get natural light and one in a dark cupboard.
Amazing to see the pea take off in the seed jar once the root popped out!
Arugula sprouts or microgreens are harvested when they are young, usually when they are 2 inches tall or less. The sprouts are ready for harvest when their first two immature leaves are plump and fully formed but before true leaves form. Nighttime and morning are the best times to harvest microgreens, according to University of Florida IFAS Gardening Solutions. Snip off the sprouts at the base using clean scissors and wash them in clean water immediately. They can be eaten right away or stored in a breathable plastic container in the refrigerator for five to six days.
Arugula must have bright light, good air circulation and sterile, fast-draining soil to produce healthy and sanitary sprouts. Grow sprouts in a wide container with drainage holes at the base. Fill the container to within 1 inch of the top with moist, sterile seed-growing compost, which is normally comprised of sphagnum, perlite, coir and other ingredients that will provide the right moisture balance for seedlings.
Position the pots on a bright, sunny windowsill with western, eastern or southern exposure and good air flow. Keep the compost barely moist while the seeds germinate, which will take roughly two weeks for Italian arugula and 10 days for common arugula. Arugula growing temperatures are variable. The seeds germinate well at temperatures as low as 40 to 55 degrees Fahrenheit, according to Cornell University, but they will also tolerate warmer temperatures as well.
Growing Arugula in the Garden
Spread the arugula seeds across the surface of the compost at a rate of 10 to 12 seeds per square inch, as recommended by University of Florida IFAS Gardening Solutions. Cover the seeds with a 1/4-inch-thick layer of moist compost.
The sprouts take just weeks to grow, so they can be started and harvested in successive waves to provide you with a supply of nutrient-dense and tasty sprouts year-round.
In milder climates, it is possible to grow arugula sprouts in the garden year-round. The UC Master Gardener Program of Sonoma County recommends choosing a location with at least four hours of direct sunlight each day and moist soil with good drainage. Adding a 3- to 4-inch-thick layer of compost to the top 10 inches of soil will provide all the nutrients that the arugula sprouts will need as they grow. Scatter the seeds across the surface of the soil at a rate of 10 to 12 seeds per square inch and then cover them with a scant, 1/4-inch-thick layer of soil. Water well with a mister.
When it comes to growing arugula, problems are rare. Keep the seeds moist and watch for sprouts in two weeks for Italian arugula and 10 days for common arugula. The seedlings can withstand very cold temperatures but will need protection if temperatures fall below 28 degrees for longer than four hours. During the warmer months, arugula benefits from a shade cloth with a 40- to 60-percent density to keep the tender, delicate leaves from getting bitter. Keep the sprouts well watered.
