The United States is divided into 15 broad ecological regions, each one home to a variety of fascinating native plants. In the Southwest, creosote bushes are found in and around the Mojave, Chihuahuan, and Sonoran deserts at elevations below 5,000 feet and is one of the oldest living things on Earth--approximately 11,700 years old. This evergreen…

Will spring be early next year? This is a question the authors ponder each fall as they prepare for a yearlong citizen science project with kindergartners. Citizen science projects naturally promote the development of science and engineering practices. These projects can be integrated at any grade level and aligned to meet other content areas as…

This column includes activities inspired by children's literature. This month's issue has students experience nature by examining how seeds are transported from one location to another or consider what it takes for organisms to survive in an environment. Both activities allow elementary-age children to think about how outdoor spaces can be…

The authors describe how grade 4 students carried out an investigation about growing cucumbers (members of the curcurbit or gourd family) where they read information sources about seed variety; germinated seeds under different conditions; measured and partitioned growing spaces; collected and analyzed data on germination, true leaf growth, and…

Severe flooding was prevalent within the authors' region at the beginning of the school year. Many homes and fields were affected by the amount of rain that fell within a short period of time over multiple days. Their students were concerned about the impact this natural phenomena was having on their local community. Natural phenomena can provide…

In this article Rebecca Kurson describes her school garden, now in its second year, as one that the lower school (preK-5) students plant and observe as often as possible. They call the garden an "outdoor classroom," and the younger students are particularly interested in how the plants grow. Kruson had lots of garden activities…

This column presents ideas and techniques to enhance science teaching. In the "Talking Window Garden" project, students create "smart" plant pots that use sensors to collect and analyze data on the health of their plants. The Talking Window Garden project was a collaborative effort between an elementary teacher who wanted to…

A team of science teacher educators working in collaboration with local elementary schools explored opportunities for science and engineering "learning by doing" in the particular context of urban elementary school communities. In this article, the authors present design task that helps students identify and find solutions to a…

Many young children come to school with prior experiences planting seeds in a garden or in a pot, watering them, and seeing them grow. These early scientific investigations are designed to help children understand that seeds need water, something to grow in (such as soil), and the right temperature to sprout--if these conditions are met, a seed…

Children may not be aware of the origin of much of their food, especially if they eat mostly processed foods. Schools that operate a garden are able to teach children how common foods are parts of plants. This column discusses resources and science topics related to students in grades preK to 2. In this month's issue students focus on…

This article describes a hands-on science curriculum used to teach kindergarten students about decomposition at the Riverdale Country School in the Bronx, New York. The goal was to get students to spend more time in the natural world and to have the opportunity to literally "get their hands dirty." This was premised on the idea that the…

Role-play provides fifth-grade students with the opportunity to develop meaningful connections to environmental science concepts and understand how those concepts relate to their community. Role-play also builds students' communication skills and increases their understanding of the attitudes of science. By participating in role-play, teachers…

Every year, an elementary school celebrates different aspects of Central Texas ecology. This year, they focused on Blackland Prairie, the ecoregion on which the school is located. A schoolwide event at the end of the year offers students the opportunity to teach their parents and their peers what they've learned. The Fourth- and fifth-grade…

In order to demonstrate how plants remove water from the soil and release it to the atmosphere, students compared open- and closed-growing systems using drought-tolerant and higher water requirement plants. Then, students designed a drought-tolerant garden demonstrating what they had learned. Through this experience, students not only learned…

Many people look forward to planting their own garden and enjoying its fruitage throughout the summer months. Gardening can be an excellent learning experience in many ways because it offers opportunities to learn about plants and to observe changes over time. This column focuses on a long-term project of understanding plant growth and planting…
