Children are very curious about the world around them. You may find them peering at tadpoles in a pond, counting ants on a log, or wondering about the stars, the sun, and the moon. I have been asked many times: Is the moon really made of cheese? Do astronauts live on the moon? Why does the moon look different every time I look up? Introducing…

Making and recording scientific observations is a fundamental activity of the scientific community. Scientists use their senses and tools (e.g., magnifying glasses, rulers, colored pencils) to make records of the phenomena (e.g., light energy, ecosystems) they are investigating. These observations often serve as evidence in the scientific…

Walter Alvarez, a doctor and physiologist of some renown, decided to send his scientifically talented son, Luis, to an arts and crafts school where Luis took industrial drawing and woodworking instead of calculus. Luis Alvarez won the Nobel Prize in physics in 1968. Einstein was certainly not a standout in his mathematics and physics classes. Yet…

Technology can be both a blessing and a curse in the classroom. Although technology can provide greater access to information and increase student engagement, if screen time replaces time spent outside, then students stand to lose awareness and connectivity to the surrounding natural environment. This article describes how Google Earth can foster…

English language learners (ELLs) bring a wealth of knowledge to science classrooms, yet often that knowledge is untapped by traditional instruction and assessment. As classrooms become increasingly diverse, it is critical to recognize the depth of understandings ELLs bring to classrooms to explain the scientific world around them. English language…

The "National Science Education Standards (NSES)" state that students in grades K-4 are expected to understand that astronomical objects in the sky, including the Sun, Moon, and stars--have properties, locations, and patterns of movement that can be observed and described. They further suggest using an inquiry-based approach to teach…

A simple lesson on magnetism can foster childrens' natural enthusiasm for science and set the stage for discoveries that parallel those of famous scientists. (JD)

Presents an overview of a long-term unit centering on observations of biological change. Explains the purpose, procedures, and activities of long-term projects as: watching a plot of land; seeing how a baby grows, and witnessing kitten birth and growth. Suggests additional activities which address the concept of continuity. (ML)

This article provides detailed instructions on how to hatch chicken eggs. Sections include: (1) making the incubator; (2) making the brooder; (3) guidelines for hatching eggs; (4) from incubator to brooder; and (5) recommended readings. (JMK)

Describes some of the characteristics of the common harvestmen, or daddy longlegs, and the true spider. Provides information on harvestmen's habitats and life cycles and includes tips on housing and observing these organisms in science classrooms. (TW)

The value of involving children in experiencing environmental phenomena and observing living organisms is advocated. Suggestions are presented for offering a richer set of science experiences for children. (SA)

These activities allow students to investigate behavioral responses of the large Milkweed bug, "Oncopeltus fasciatus," and the mealworm, "Tenebrio molitor" or "Tenebrio obscurus," to external stimuli of light, color, and temperature. During the activities, students formulate hypotheses to research questions presented. They also observe insects for…

Explains an integrated curriculum in which science content is at the core of teaching. Contends that study in an integrated curriculum invites students to build their world knowledge by offering them the time and continuous focus to know a subject well. Details an integrated unit called "Oceans" which included: observation; whole group…

Examines the definitions of scientific observation used in assessing students in Great Britain for the General Certificate in Secondary Education (GCSE). Proposes an instruction framework that supports such definitions. Provides examples of observational tasks and some methods of evaluating them. (TW)

Describes a lesson in which fifth graders made observations of candles. Discusses the progress of the lesson and the necessity of instructing students in what and how to watch and measure. Stresses that this can be easily accomplished inexpensively with imagination. (CW)
