In this lab design and lab skills worksheet, learners answer questions about experimental design including finding variables, determining controls, and graphing data. They answer questions about microscopy and label the parts of a...

Students explore different activities in biology, physics and chemistry. In this science instructional activity, students examine chromosomes using a microscope and explain their significance in sustaining life on Earth. They investigate...

Students observe embryogenesis in action through early stages of development of eggs. They observe cultures with dissecting and compound microscopes. They draw their egg, record any details and observe for changes. They compare their...

Students visit a local creek or stream. They collect water samples from the creek and observe and sort the "water critters" they find in the sample, observing smaller organisms under a microscope if necessary. They identify each organism...

Learners observe the cells of an onion by wet mounting it and viewing it in a microscope.  For this hands on lesson students make their own wet mount slide of an onion and are able to identify the cells in it such as, the nucleus,...

High schoolers microscopically observe various subcellular components. They determine the effects of different salt solutions on Elodea plant cells. Students explain the major function of a cell membrane and describe its structure.

Young scholars identify each phase of mitosis and the main characteristics of each. Students prepare a microscope slide with onion root tip. Young scholars observe the cell division occurring in the cells and label the mitosis phases...

Students use microscopes to investigate the diversity of life that exists in pond water. They then conduct a controlled investigation to study the effect of a pollutant (rice) on a microcosm ecosystem.

In this implicit differentiation worksheet, students use the chain rule to solve for the derivative. The find the equation for the tangent line at a given point and determine if the line is vertical. This two-page worksheet contains...

For this chemistry worksheet, high schoolers fill in 10 blanks with the appropriate term, they determine if 4 statements are true or false, they match 6 terms with their definitions and they answer 3 questions. Topics include areas of...

Students investigate how trees produce their own food. They examine chlorophyll cells with a microscope, analyze a cross section of a log, determine how old the tree was, simulate the distance of the roots, and create a play.

Young scholars investigate the organisms of bacteria. They are given a culture of bacteria that can be observed under a microscope. The students make observations that are recorded. The lesson includes the mention of specific safety...

Students identify and explain that remote sensing can detect changes on the Earth's surface that occur over time, and name at least three: urbanization, deforestation, and succession. They select a global change issue to investigate and...

Students consider the causes of density at a microscopic level. They then discover that one cause of density has to do with how many protons and neutrons the material contains.

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 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.

Students study the water quality of a stream in their area, by measuring the temperature, pH, alkalinity and conductivity. They integrate biology with earth science when using the microscope to study the living organisms in the water.

In this blood vessel worksheet, students compare microscope slides of arteries, veins, and capillaries. This worksheet has 43 fill in the blank questions.

Learners use the macro mode of the OLYMPUS FE-140 CAMERAS as virtual microscopes to explore different habitats, observe plants, soil, and insects and other creatures. They download those images on electronic files and build web pages....

Students recognize slides of different fungi. They work in lab groups. Students view slides under the microscope, then draw and label the parts, magnification, and the organism. Students discuss similarities between some fungi and...

Students prepare single strands of muscle cell. They microscopically examine muscle cells and identify bands of darker and lighter proteins. They predict, observe, describe and quantify the effects of ions and ATP.

Students perform a simulation of the workings of an electron microscope to discover that the resolution will need to improved to detect objects in the nano-scale. They use wooden dowels as detectors to determine the shape of objects in...

Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

Expectant earth scientists examine the bottom side of a leaf and learn the role of the stomata. They consider the gas exchange that occurs through these structures and relate how the climate is changing to its impact on food crops. This...
