Even though they were written for upper-level high schoolers or college pupils, the labs herein are possible to use even in middle school. In the activity, kids observe osmosis in both potatoes and elodea plants, then record and graph...

Life science learners investigate live cells. They examine wet mount slides of cyanobacteria and Elodea plants. They peer into the dynamic microscopic world of protists. Afterward, they construct a model of a cell, including rudimentary...

Young scholars investigate the concept of diffusion through a membrane. They do this through the conduction of a simple experiment. Students make observations while determining if the smell of different chemicals seeps through the...

Seventh graders study biological systems and how they reach equilibrium.  In this system balance lesson students divide into groups and complete an osmosis lab activity.

Students participate in an experiment to help them explain specular and diffusion reflection.

Semipermeable membranes allow water to go through—but not larger molecules. The simulation encourages pupils to adjust the membrane pore size to understand how this works. It also provides a way to trace the movement of a single molecule.

Why can we see our reflection in a window but not a brick wall? Young physicists learn the Law of Reflection and various light properties that help them answer this and other questions about reflection. Use the PowerPoint to introduce...

Young scholars engage in an experiment for the scientific concept of diffusion of particles. There are instructions for classroom set up prior to conduction of the activity. Students sit in the classroom that is filled with the smell of...

Students examine the basics of starch and how it is used in food. In this photosynthesis lesson students experiment with variables that affect starch production in photosynthesis.

Students explore diffusion or scattering of light. In this physics lesson, students explain why the sky is blue and sunsets/sunrises are red.

Students conduct various experiments on glucose. In this biology lesson, students differentiate the process of diffusion and osmosis. They test different foods for the presence of glucose and starch.

Students obseve and compare molecular movement within water at various temperatures and of varying salinity. They discuss the movement of water on a larger scale which can affect the movement and concentrations of microbial populations...

Students investigate osmotic balance in living cells. In this osmotic balance lesson plan, students use elodea leaves to study the effects of salt solutions on the cell. They compare the changes in an elodea leaf with salt water on it to...

Explore the behavior of light waves with a lab activity. Scholars build new vocabulary through experimentation and observation. Using different mediums, they model reflection, refraction, transmission, diffusion, and scattering of light.

Students are given materials with various textures and light sources to investigate specular reflection, diffuse, reflection, angle of incidence, and angle of reflection. Students draw and label an everyday scenario showing specular and...

In this diffusion worksheet, students review the terms associated with diffusion and osmosis plus answer questions based on a passive transport lab they completed. This worksheet has 8 short answer questions.

How did Rutherford determine that the nucleus was the center of an atom? Take a look inside the famous Gold Foil Experiment with an interesting interactive. Learners fire a beam of alpha particles at a nucleus containing variable...

Learners investigate the causes of carbon monoxide in mines and other common sources of CO. Pupils read the worksheet "Canary in a Coal Mine" before beginning this investigation. They discuss ethical issues regarding treatment of miners...

Lead your high school class on an exploration inside the cell. Individuals investigate the relationships between cells structure and function given their relative locations on the cell membrane. They explore the concept of homeostasis...

Students measure the rate of diffusion and to calculate the surface area to volume ratios of varying cell sizes. The instructional activity is very clearly organized with a useful student worksheet provided. They perform a lab experiment...

Students participate in a lab experiment to observe and measure the opening and closing of stomata. They focus on photoperiod, locate and identify stomata on a leaf and explain the role of stomata in the daily functioning of a plant.

Learners conduct a series of activities to explore the nature of cells. In this biology lesson, students observe plant and animal cells under the microscope and compare them. They differentiate osmosis and diffusion.

Students participate in a review of diffusion and the basic properties of the cell membrane before exploring the process of osmosis in a lab activity. Using shell-less eggs that have soaked in various solutions, students make...

Fourth graders engage in this interactive instructional activity which illustrates diffusion and osmosis and shows them that molecules of life move dynamically and powerfully. They must analyze their lab orally and in writing.
