Micropipettes are tools that allow scientists to measure and utilize very small volumes of liquid in the microliter to milliliter range. This scrollable introduces the parts of a micropipette and the proper use of this equipment in the lab.
Este vídeo de laboratório discute o propósito da centrifugação em um laboratório biológico e demonstra duas aplicações.
Students learn about the current applications and limitations of 3D bioprinting, as well as its amazing future potential. This lesson, and its fun associated activity, provides a unique way to review and explore concepts such as differing cell functions, multicellular organism complexity, and engineering design steps. As introduced through a PowerPoint® presentation, students learn about three different types of bioprinters, with a focus on the extrusion model. Then they learn the basics of tissue engineering and the steps to design printed tissues. This background information prepares students to conduct the associated activity in which they use mock-3D bioprinters composed of a desktop setup that uses bags of icing to “bioprint” replacement skin, bone and muscle for a fictitious trauma patient, Bill. A pre/post-quiz is also provided.
This activity is a field investigation where students will observe, discuss, and gather evidence on how environmental changes affect animals that live in that habitat.
Students will investigate the organization of all living things through and learn how to classify through process of classifying their own shoes. Students will complete the classification of a Jaguar and write their own pneumonic device to remember the order of biological classification. (kingdom, phylum, class, order, family, genus, species)
This activity is an interactive game that helps students learn that vertebrates are classified into five groups and that each group has common characteristics that distinguish the animal group from other respective groups.
Students observe the decomposition of a pumpkin under controlled circumstances. These observations are used to take notes and develop questions.
This activity is a field investigation in which students identify organisms and their energy sources. Students collect data and create a food web that explains how the organisms in their ecosystem are related.
This activity is a presentation of honeybee anatomy and behavior.
This activity is a field investigation where students collect insects to analyze, observe, and classify
Short Description: This activity is a classroom investigation of human joints. Students will identify joints and use their science notebooks to record their findings using drawings and words.
This activity is a classroom investigation where students gather descriptive data on two different plants with a partner, and on other plants during a classroom discussion.They will then interpret their findings, and classify the plants, if applicable, into monocots or dicots.
In this Museum Mondays episode from the Cleveland Museum of Natural History, Dr. Denise Su, Chief Academic Engagement Officer, Gertrude Haskell Britton Endowed Chair of Education, and Curator of Paleobotany & Paleoecology, tours the Human Origins Gallery, discussing the environment in which Lucy likely lived. Features a video and downloadable worksheet.
Dr. Denise Su, Chief Academic Engagement Officer, Gertrude Haskell Britton Endowed Chair of Education, and Curator of Paleobotany & Paleoecology, tours the Human Origins Gallery, discussing the environment in which Lucy likely lived. Worksheet available for grades 5-12.
This field and classroom activity involves identification of similarities, differences, advantages, and disadvantages in survival, method of locomotion, food acquisition, and reproduction in three fresh-water microbes.
This is an investigative lab to provide students with an opportunity to practice observation skills and develop cooperative group proceedures.
This activity is a classroom lab where the students gather data on the affect water has on gummy bear candies and develops an experiment based on a new question regarding a not plain water solution. Students will perform calculations and graph their results.
This first grade field and classroom activity leads students to discover their natural world through observation and measurement.
Students design and conduct simple experiments using elodea (aquatic plant sold in pet stores) and Bromthymol blue to determine whether plants consume or release carbon dioxide in the process of photosynthesis. Students will record their data which will be used to conclude whether carbon dioxide was consumed or released by the elodea. Through class discussion of student data, students will learn that carbon dioxide was consumed during photosynthesis.
Students work in pairs to compare five aspects of an organism that reproduces sexually, asexually, or both sexually and asexually. The activity comes with a chart for the students to fill out and with information sheets on twelve organisms. As a class, students share their comparisons and generate a list of general characteristics for each mode of reproduction and then discuss the advantages and disadvantages of both. Included in the discussion are reproductive mechanisms and genetic variation.
