Little learners experiment with sunlight and map out how light travels. Using a mirror and slotted card, they find out about items that can reflect or absorb the light. They experiment with a variety of materials to find out how light...

Students in this inquiry-based experiment, put in the role of a method development chemist. The scenario they are given is that a train wreck has occurred resulting in a chemical spill. Students are told that the spill mixture consists...

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

Advanced chemistry scholars read about gas chromatography as a means of separating mixtures into their components. Then they try the technique on fingernail polish remover. Detailed instructions are provided via a lab sheet for your...

Young scholars reach out into the community and learn about different environmental science careers in this inquiry-based instructional activity. Beginning with a short research assignment, children gain background knowledge about...

Lights, shadows, action, and inquiry await your artistic scientists. They explore the way light travels, absorbs, reflects, and transmits through shadow play. They create folktale-inspired shadow puppets, explore the science of light,...

Why is lactase important? Biology scholars explore enzyme function in a structured inquiry lab. The activity tasks lab groups with observing how temperature and pH affect enzyme activity, as well as determining which milk products...

Microchips are a man-made wonder. Investigate the manufacturing wonder with a hands-on inquiry-based instructional activity. Scholars simulate the process of pattern transfer using photoresist. Their conclusion identifies how their...

Through inquiry and exploration, 4th graders will learn and understand the functions of open and closed circuits. They will break into 2 groups, define vocabulary, hypothesize how to light a bulb, then test their hypothesis 4 different...

Scientists need to figure out how to measure interplanetary magnetic fields, but the magnetic field of the spacecraft is interfering with their readings. Scholars attempt to solve the problem that has perplexed NASA scientists for years.

Students read excerpts from Annie Dillard's memoir, "An American Childhood," with the teacher. They experience opportunities to connect English, science, nature and art together from a new and unique perspective. This approach serves as...

As an anticipatory set, young environmental technicians watch a video about how ocean temperatures seem to be changing along with the global climate. They perform a laboratory demonstration with the purpose of observing what happens to...

Students participate in a three-part lab in which they investigate plant pigments. Part I is designed to teach basic laboratory techniques of column chromatography, in Part II students design an experiment to separate the components of a...

Students investigate the spectroscopic colors unique to elements, and to use this information to create a specific color. They follow a detailed schematic to produce a spectroscpoe to be used in the testing.

Students investigate the cause of death of a fictitious school janitor. They develop hypotheses based on information discovered by examining the labels of household chemicals.

Students work with "ice" in order to gain a practical application of math concepts that evolve into an inquiry-based study. They determine if the dimensions of the ice make a difference in the way the ice floats in the water.

Students conduct inquiry-based research for basic information about microbes, infections, and HIV, the virus that causes AIDS. After gathering answers to their questions, students develop a presentation to post on their school's Web site.

Learners experiment with various foods to determine fat and starch content. They rub jam, peanut butter, bananas, and other foods in a small circle on a piece of paper, and observe the results. If there is a high fat content in the...

Requiring more than one class period, this resource takes earth science learners on a journey through a watershed. Using ArcGIS Explorer, an online geographic information system, they view maps of watersheds and surrounding landscapes....

Where can you see an aurora in North America? After completing an astronomy activity, scholars can locate the exact coordinates. Pupils plot points of the inner and outer ring of the auroral oval and answer questions based on...

A video and laboratory investigation are highlights to this lesson on acidification of ocean water due to increased atmospheric carbon dioxide. Using bromothymol blue (BTB) as an indicator, pupils analyze the amount of carbon dioxide...

Sometimes science lab can be ... delicious! Middle school science scholars extract DNA from strawberries and other fruits in an engaging lab activity. The teacher's guide includes pacing, materials list, and worksheets with answer keys.
