The hypothesis is that the Peperomia plant’s roots grow faster in hydroponics solution than in soil.

You will cut 10 pieces of the Peperomia plant stem into 8 cm lengths, label 5 plastic containers “soil 1” to “soil 5” and 5 plastic containers “hydro 1” to “hydro 5”, make 3 holes at the bottom of the plastic containers marked “soil 1” to “soil 5”, fill these containers with soil, plant 1 Peperomia plant stem in each of the container, mix the hydroponics plant nutrient is with water according to the instructions stated on the packaging, pour the mixture into the plastic containers marked “hydro 1” to “hydro 5”, place 1 Peperomia plant stem in each of the container, and place the 10 plastic containers at a place where there is adequate sunlight.

You will need 1 Peperomia plant, 10 plastic containers, 5 plastic containers filled with soil, 1 bottle of hydroponic plant food, 1 pair of scissors, tap water, 1 ruler, and 1 black marker pen.

After 3 weeks, the roots of the Peperomia plants in the hydroponics solution were longer, compared with the ones planted in soil.

This science project is interesting because it shows how hydroponics can be used to grow plants in places with insufficient arable land, and how it can produce a higher crop yield and be carried out all year round.

Variations of this science project include using different types of plants and different types of nutrient solutions to see if they affect the rate of growth of the roots.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
