Students study classification schemes for identifying sunspots. They distinguish between sunspot unbrae and penunbrae, measure sunspots, and compare them to the size of the Earth. They complete a worksheet showing classification of...

Students compare and contrast the visible structures of three insects based on photographs. They differentiate characteristics of crane flies, ants, and wasps then create a simple classification system.

Second graders examine the properties of liquids and their classifications. They compare and contrast cups of different liquids and record their findings in journals. Students observe how liquids flow at various speeds and that unlike...

Squeak squeak! A four-page mini book shows learners some examples of rodents. After a lesson about mice, rats, and squirrels, have your class color these pages and publish their own rodent books.

Two blooms of phytoplankton, instead of just one, now occur in the Arctic due to declining sea ice, which will have widespread effects on the marine life and climate. In small groups, participants build an Arctic food web with given...

It is a long way from nano to macro. Learners examined the scale of measurement from macro to nano in the first four lessons of the five-part series. With the final installment, they review what they learned by classifying objects in one...

Crazy fact: Some animals can survive months without oxygen. An online resource describes some unique ways animals collect oxygen and even live without it for an extended time. Learners read about these special animals and use pop-up...

Learners view NASA images of galaxies and develop a galaxy classification scheme. They compare and contrast their classification scheme with that developed by Edwin Hubble. They recognize that galaxies are collections of billions of stars.

Test your students' science and/or reading comprehension skills with this activity, which provides a page of information about clouds and cloud classification. Both an earth science teacher and a language arts teacher could use this...

Students explore the topics of ocean water salinity, ocean life zones, marine life classification, and ocean food chains. They observe demonstrations, conduct experiments, complete quizzes and handouts, and analyze key vocabulary.

Students germinate a Mung Bean seed. For this seed lesson students conduct an experiment germinating a Mung Bean. They apply three different treatments to the seeds: dry, moist, and underwater incubation.

Students simulate different spacecraft missions using materials provided. In this space science lesson, students observe and record a planetary model's features from a distance. They relate this activity to scientists' space exploration...

Students classify microorganisms into categories based on their characteristics. Pupils use a taxonomic key to identify organisms. They classify certain bacteria, protists, and viruses using a classification or taxonmic key.

Young scholars investigate classifying animals. For this animal classification lesson, students choose three animals that use camouflage and list three facts about that animal. Young scholars create a story about the animal, present it...
