Some basic descriptions of DNA and the appearance of structures in a bacteria are included along with great diagrams.  The presentation has clear, but detailed slides, and your students will find the information about Gram staining...

Students collect samples of common dust from their homes and school for examination under a microscope. They identify the components of their samples using the provided "Atlas of Indoor Dust Particles." Pupils take samples form a variety...

Plankton isn't just a tiny cartoon character, it's also a very important food source for animals around the world. Budding scientists discuss the types and functions of plankton, including where they are found, how they are caught, and...

What happens to the wood a termite eats? Pupils learn about the three types of symbiosis with pictures of symbiotic pairs. Afterward, they determine whether there is a symbiotic relationship with a termite by dissecting termites and...

Drugs can both help and harm depending on how they are used. Fifth graders complete a worksheet that provides background information on prescription drugs. They read the text and then describe why medication manufacturers label pill...

Students take on the role of epidemiologists. They investigate an "outbreak" in serious birth defects that occur in infants born to teenage girls. students discover a link between the use of the acne drug called Accutane and birth defects.

In this life cycle workbook, 5th graders examine plant and animal cells, classification of organisms, human biology, photosynthesis, and natural environments. 21 different activities make up the Life Cycle Workbook.

Students collect and describe cells from an onion root tip which are undergoing the stages of cell division. They use a ProScope USB microscope to identify and compare cells in five phases of mitosis.

Ninth graders design and conduct an experiment. They evaluate other's experiments. Students describe relationships between biological systems and the environmental contaminants. They work as a team to solve a problem.

Here is a lab activity where teens experience the respiratory system first-hand as they dissect lungs and identify key structures within the system. Although the website is written in British English with some slightly different verbiage...

Students investigate how mutations lead to changes in cell structure and function. They construct an oligonucleotide, identify a protein sequence, design a step-by-step mechanism of how they think cells repair damaged DNA, and prepare...

Students determine the approximate time a cell spends in each phase of mitosis by counting cells in each phase from a prepared slide. They use a few simple calculations to estimate how long cells spend in each cycle in the body.

Fourth graders observe brine shrimp over several days. They create drawings showing the growth and development of the shrimp. They research web sites to find out where brine shrimp fit on the food chain and what makes the shrimp unique.

Students observe the reaction of living cells to mechanical and chemical stimuli by introducing different stimuli to an organism under a microscope and recording the response.

Students take measurements of the distance between the objective and the slide when in focus with each objective. They determine the diameter of the field of view at each power in order to determine the size of the cells being observed.

Students identify and describe various organisms living in a pond water environment. They describe the characteristics of living things. Students compare and contrast organisms created by asexual reproduction and sexual reproduction....

High schoolers explore chromosome karyotyping. In this chromosome karyotyping lesson plan, students use a chromosome kit to explore chromosome syndromes and disorders. They also produce a large model of a cell with chromosome to simulate...

Students observe the general structure and organelles of plant and animal cells. Students prepare microscope slides of elodea, onion, check, and cork and identify the cells by size and shape as unicellular, multicellular, plant or animal.

Seventh graders describe the processes involved in mitosis and meiosis. In this life science lesson, 7th graders create chromosome models using strings and beads. They play a jeopardy team game at the end of the unit to review concepts...

Students investigate cells. They discover what cells are, where they are found, what they do and what they are made of. They construct a giant cell that is posted on the bulletin board.

Learners collect samples of pond water, dried grass, and soil in a jar. They predict the order of ecological succession in their pond water cultures. They compare their expected results with their observed results.

Students explore composting. In this composting lesson, students use compound microscopes to observe the microbial communities in compost. Observations and documentation of changes will occur over the course of several weeks.

Students use microscopes to observe E. coli bacateria on prepared slides and in a live culture. They use micro-slide viewers to observe the shapes of various bacteria and the structures within the bacterial cell. Students make an...

Students witness various stages of mitosis through preparing onion root tip slides. With teacher guidance, they learn a great deal through the hands-on process of preparing the slides themselves.
