In this vocabulary worksheet, pupils complete multiple choice, fill in the blank, and short answer questions to define vocabulary words. Students complete 20 problems.

Students design an experiment to determine the best conditions for molds growth. In this biology lesson, students collect data for a week and analyze their findings. They create a presentation and share them with the class.

Students identify the causes of hypothermia. In this biology lesson, students investigate the different types of heat transfer and heat loss. They discuss several practical measures to avoid hypothermia.

In this light and optics instructional activity, students match the light and optics vocabulary with their definitions. Students match 21 words to their definitions.

In this optics worksheet, students read about how light can reflect or refract and how lenses and mirrors work. Then students complete 13 matching, 27 fill in the blank, and 8 word problems.

In this optics activity, students read about refraction and reflection, lenses and mirrors, and objects and images. They answer 13 matching questions about light rays, light behavior and types of lenses. They also answer 9 questions such...

Students build a telescope and give quantification of its magnification and field of view while making observations regarding images. In this telescope lesson, students use a simple lens to project a scene and examine various telescope...

Young scholars explore the basic skills guiding sound scientific invvestigation and methodology. They are introduced to a powerful scientific tool-the microscope. Students review the parts of the microscope. They discuss the inventor...

Students analyze a microscope and study what they do.  For this investigative lesson students study how microscopes were first invented, and how ray diagrams are used in conjunction. 

In this microscope worksheet, learners use an on line site to answer questions about the history of the microscope, they view objects and identify what each is, they explore different magnifications of the microscope and they answer...

Students explain how telescopes work and how they can contribute to our knowledge of the universe.

Students observe natural objects carefully and note intricate design and structure beyond surface form.

Second graders investigate rice or gohan as it's called in Japan in a couple of experiments. They tally the results.

Students group objects by their physical characteristics and various compositions using literature to stimulate recall.

Students examine the functions of earthworms and their effect on soil. They conduct an earthworm dissection lab, and complete a checklist.

Students investigate how food, clothing and shelter come from soil after they examine soil from their own backyards. They map soils on the color wheel before making glue and soil pictures and tie-dying T-shirts in red soil.

Students examine and identify plant parts to recognize specific weeds, identify three different weeds, discern differences in weeds quickly, evaluate classmates' weed recognition, and discuss what strategies they used to identify weeds.

Fourth graders examine various types of rocks and record their properties. They collect rocks at home and bring them to school where they are mixed and distributed to groups of students. After writing their observations on...
