A recipe, no matter its format, gives ingredients and instructions for a specific food so that the food item tastes the same every time. See Preface Materials:

Fifth graders investigate evidence for changes in matter that occur during a chemical reaction.

Learners share their own opinions about proper and poor etiquette in school. After reading an article, they discover matters of etiquette and conflict that occur during holiday rituals. They role-play the potential conflicts and...

Students discuss waves and sound travel. They experiment with tin-can telephones, and telephones made of different materials including paper, foam, and plastic and record their results on an record sheet. Students explain why size...

Students explore activities that might some day bring "justice for all" to their communities. They assess how justice is a day-to-day, life or death matter that faces their communities. Interviews are conducted to explain how justice is...

Students identify animals in ecosystem depicted on 16th Century ceramic basin and classify them as herbivores, carnivores, or omnivores based on physical characteristics and prior knowledge, determine which life forms in ecosystem are...

Students explore objects before and after heating using their senses.  In this matter and energy lesson, students experiment with a variety of objects and use their senses (except taste) to make predictions and record observations...

Young scholars explore how various substances change from a solid to a liquid or from a liquid to a solid and how temperature, pressure and nature play an important role in this process. In this melting and freezing...

Students examine how temperature effects changes in materials. In this physical science lesson, students use food coloring and cups of water of varying temperatures to observe the effects temperature has on matter. Students predict and...

Students, in groups, research ancient Egyptian civilization. They write articles and publish them in a magazine format.

Learners investigate the process that occurs when liquids evaporaate. They test water and alcohol to determine which substance evaporates more quickly and relate the rate to energy changes.

Young biologists trace the path of the sun's energy through marine ecosystems in the second part of this four-lesson series. Building on prior knowledge about producers, consumers, and decomposers students are introduced to the...

Think about your favorite place ... now, think about what it looks like at different times during the day. How does the change in lighting affect the colors you see? Young artists explore the tools available in digital art software to...

How is it possible for ocean water to have layers? The sixth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates factors that cause different water densities to occur. Experiments...

Students explore visosity of matter. They run tests of various liquid substances to observe and compare rates of flow of different substances. In addition, they relate viscosity to distance travelled by sample substances.

Students explore properties of cans (including aluminum and steel) as they rotate through stations. They experiment with magnets, weight differences, resistance to corrosion and temperature conductivity.

Students identify the various states of water and its natural flow downward. As a class, students take digital pictures of different forms of water and create a multimedia presentation describing their photographs. Groups of students...

Students research, using the Internet, specified Civil War battles in order to prepare an oral presentation for the class. They, in small groups, present using images and maps. They take a quiz on the subject matter and evaluate the web...

Young scholars investigate water pollution. They develop an understanding of the behavior of organisms, of the structure and properties of matter, and of natural and human induced hazards by conducting lab tests. They present their data...

Second graders read the story, "The Foolish, Timid Rabbit," as part of a unit on appearances. After reading with partners, they write their own stories that include elements about some forms of matter from their science studies. Students...

First graders investigate composting. In this biology lesson, 1st graders identify ways to use garbage as fertilizer. Students examine soil and compost matter as well as the role of worms in the dirt.

Alone, or as part of the intended unit on chemical reactions, this activity allows learners to experience an exothermic reaction. Here, learners add calcium chloride to a baking soda solution and watch the temperature rise! They will...

Investigators construct a makeshift balance and compare equal volumes of wax and water. They do the same for clay and water. Then they discover whether the wax and clay will float or sink in water. Ultimately this is a comparison of...

First graders understand that gases take up space even though you can't see or smell it. This is done through many experiments like trapping air in different sized bags, using balloons and plastic bottles, and blowing bubbles. They...
