Can science scholars describe a nucleus without mentioning DNA, or a chloroplast without mentioning the color green? Test their organelle understanding through an exciting card game. Groups take turns guessing the correct organelle or...

Why do some smells, like popcorn, linger when others seem to vanish as quickly as they arrive? Learners think through that concept then complete an online simulation to determine if temperature and/or mass affect diffusion. Next, pupils...

This 60-question comprehensive exam was designed to determine who would go on to compete in the 2000 US National Chemistry Olympiad. Hopefuls answer multiple choice questions regarding all chemistry topics taught in the first year...

A thorough investigation of cell transport is provided when completing the assignment. The first half requires biology class members to answer questions about diffusion and osmosis with the aid of diagrams. Then they fashion an...

Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...

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...

Use salmon eggs as a cell model for demonstrating the movement of water over concentration gradients. Junior scientists examine the same process microscopically with an onion cell. They use a thistle tube and a semipermeable membrane to...

Biology buffs illustrate the workings of the cell membrane when they complete this checklist. Not only do they draw the structure, they also draw gradients and mechanisms for the transport of materials across the membrane. Your advanced...

Your students will love this PowerPoint! Great visuals will support understanding of membrane proteins, cell membranes, active transport, and diffusion. There are a lot of details on each page and all are relevant. The presentation could...

Initially, general details about cells and single cell organisms are provided. Next, the concentration becomes cellular processes such as respiration, osmosis, diffusion, fission and mitosis.  This is an attractive PowerPoint which gives...

Just as skin covers your body limiting what can go in and out, plasma membranes cover cells to do the same. Scholars begin with a presentation that gives overview of the structure and function of plasma membranes. Then, they learn how...

Is your class ready to size up the topic of diffusion? Help them get cell shape savvy with a well-written handout. The resource covers how substances such as oxygen passively move through the cell membrane and how cell size and shape...

To better comprehend organic farming scholars conduct experiments on how plant roots remove nutrients from the soil. Through multiple activities, discussion, and instruction they relate the plant's vascular system to the human...

Cell size is limited by the surface area to volume ratio, but why is this true? Scholars measure the surface area and volume of cubes before placing them into liquid. After a set amount of time, they measure the uptake by diffusion for...

Cells are busy places! How do things move around in such a tiny environment? Introduce young life scientists to the types of cellular transport through a video that is part of a large biology playlist. Animated characters demonstrate how...

Connect the chemical aspects of coffee to the world in which we live! Scholars consider the molecules within coffee and how they interact with the environment as they view an episode of the ACS Reaction series. From caffeine as a...

Jupiter could make one mean smoothie! Discover how the massive planet helped shape the rest of our solar system through a Why with Nye! video from THNKR. The resource discusses Jupiter as the first planet in the solar system to form, how...

Does molecular mass affect the rate of diffusion? The simulation allows scholars to experiment with diffusion while varying the molecular mass and temperature. The timer automatically stops when a certain point is reached, making it easy...

Diffusion rates change with differences in temperature. See it happen through a simulation that allows scholars to explore the rates of diffusion at five different temperatures. It also allows young scientists to trace the movement of a...

Mitochondria use two semipermeable membranes to work properly. Young scientists adjust the pore size for two membranes. They then observe the diffusion of two different sizes of molecules.

Trying to learn through diffusion rather than simply studying the material rarely works for scholars. This simulation helps make learning diffusion fun. Pupils add a drop of dye to water and observe the diffusion as the molecules bounce...

Do cells breathe? An installment in the Fuse School series of videos describes how cells take in the nutrients they need and release the waste they don't need. It highlights the process of diffusion and osmosis.

Why do balloons go flat over time? The answer lies in the behavior of gases! Introduce young scientists to diffusion and effusion with a video. Pupils learn the composition and partial pressures of atmospheric gases as well as how the...
