Students use oranges to informally explore decomposition, dehydration, fermentation, the water cycle, bacteria, yeast, food webs, the needs of living things, and physical vs. chemical change over a period of three or more months.

Young scholars explore DNA recombination. In this biology lesson, students observe the growth of microscopic species. They predict the phenotype of the transformed colonies.

Learners demonstrate that, although we sometimes can neither smell nor taste them, many ingredients in our foods and household products come from the sea. They also investigate food eat to determine algae derivatives they contain.

Students study Drosophila by catching them. They construct catcher-containers to catch Drosophila using fruit as bait. After collection, they examine the flies and collect data to be displayed.

Students study the structure and habitat of the hydra in this lab instructional activity. Students determine if the hydra can be used as an indicator to detect pollution from automobile exhaust.

Students study ponds and wetland ecosystems and examine the food chains and webs in them.  In this aquatic ecosystems lesson students answer questions about the diversity of the flora and fauna in a pond. 

Students view bacteria through a microscope. They draw and label the bacteria using microbiology software loaded onto their Palms.

Students investigate ecological systems and the multiple uses of the environment by studying the osprey population.

Young scholars view slides or live specimens to name and describe the distinguishing features of groups of arthropods, especially spiders and insects. They complete worksheets, observe webs and then search for and record where spiders...

Learners demonstrate that living organisms may possess incredible adaptations which enable them to survive. They observe bacteria that are able to orient themselves using the Earth's magnetic field and formulate a hypothesis as to how...

Students collect and identify micrometeorites from space. Students create collection devices and retrieval methods for matter. They prepare slides and view particles found. Students discuss where the identifiable particles originated...

In this kidneys worksheet, students review the structure and function of the kidneys in the human body. This worksheet has 18 fill in the blank statements.

Seventh graders write observations of organisms based on both audio and video sources. They describe organisms which they view using appropriate adjectives.

Students investigate the different bioluminescent organisms. They use microscopes in order to make observations and draw what is seen. Students demonstrate they have studies the differences between the process of photosynthesis and...

Seventh graders complete two experiments to learn about harmful and helpful microorganisms. In this microorganisms lesson, 7th graders read background information about fungi, yeast, and club fungi. Students then complete two experiments...

Seventh graders use technology to review cell structure and function. In this cells less, 7th graders review the parts and functions of a cell, and use photography/video and PowerPoint to enhance their explorations.

Learners explain why dissolved oxygen is important in aquatic ecosystems. They evaluate the optimal dissolved oxygen levels for living organisms.

Students solve the mystery of the kidnapped teacher by analyzing a ransom note using paper chromatography. They carefully prepare ink samples from the note to known ink samples to determine the kidnapper.

Small but mighty! Learners explore the role of microbes in a healthy ecosystem. An engaging lesson asks pupils to design an aquaponics system that demonstrates that healthy microbes are necessary to maintain the ecosystem.

Pupils grow grass or radish seeds in this experiment, which takes three to four weeks to complete. They become familiar with basic soil analysis techniques, as well as, explore the importance of analyzing soil samples.

Students explore the concept of anti-counterfeiting measure.  In this economics lesson, students use science equipment to discover anti-counterfeiting designs.  Students then explore other denominations of bills. 

Young scholars create a sustainable, self-contained ecosystem in a ten-gallon aquarium.

Learners select one of the ideas for a science project reflecting their knowledge about coal. They then choose a catchy title to spark interest that describes their project. They use the scientific method to explain the process.

Students in pairs explore the transmission of the Plague, through experimentation. Cooperative groups use the scientific method to solve the fictional problem of a bacteria spreading in the Amazon. Groups also create a vector to visually...
