Evidence is mounting that children have decreasing exposure to the natural world, which makes sense as the population of the planet urbanizes and many interests and assignments involve digital technology. According to the United Nations, 54% of the world's population now live in cities (2014), and a 2010 study by the Kaiser Health Foundation found…

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…

Everyone has problems, from the smallest ant competing for a food source to the largest elephant needing to cool down. Fortunately, organisms have structures that function to help them solve these problems. So when a group of fourth-grade students look for solutions to their problems, who do they turn to? A biological champion, of course! Plants…

This article describes the final lesson within a seven-day STEM and literacy unit that is part of the Picture STEM curriculum (pictureSTEM. org) and uses engineering to integrate science and mathematics learning in a meaningful way (Tank and Moore 2013). For this engineering challenge, students used nature as a source of inspiration for designs to…

Fourth-grade students at Cutchogue East Elementary School in Cutchogue, New York learned about dependence on natural resources for survival on a visit to Downs Farm Preserve at Fort Corchaug. This is a slice of preserved land just eight minutes beyond the classroom walls. Its inhabitants date back to the first hunting and gathering settlers--the…

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…

Children are naturally curious about the world in which they live. To focus this sense of wonder, have your students investigate their local habitat as it changes over the year. This multiseason study will build connections and add relevance to the habitats that children learn about. This series of activities for grades 4-6 explores the changing…

Effective instruction requires continual assessment of student understanding to identify and redirect misconceptions. This is particularly important when dealing with topics that seem straightforward to the teacher but may go beyond the personal experience of many students, such as the life cycle of flowering plants. Life cycles are a core topic…

Digital cameras are easy to find, easy to use, and offer great potential for incorporating technology into lessons. Project ideas can range from creating collections of objects to identify (e.g., insects, plants, rocks/minerals, and so on) to documenting the signs of the seasons or recording the progress of an investigation. Even stages of the…

Children love observing seeds change as they germinate and grow into tall healthy plants, but how can teachers make investigating plants an exciting and immediate event? Microscopy might just be the answer. Although most students have seen flowers, not many have looked closely at their various structures or seen their colorful designs only…
