Curated OER
Investigating Osmosis
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...
Curated OER
Diffusion across a Selectively Permeable Membrane
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...
Curated OER
Fossil Fuels (Part II), The Geology of Oil
More of a mini-unit than a lesson, these activities lead inquisitors through a survey of oil deposits. In the first part, they read about and view diagrams of sedimentary rock layers that trap oil. Next, they test porosity and...

Investigating Factors That Affect Cell Membrane Permeability
Cell membranes and the factors that affect its integrity are studied, with Beet tissue used as the model. A poster to display findings of the permeability of the membranes would clarify understanding and also allow a layer of language...
Purdue University
Design of an Earthen Dam for a Lafayette Neighborhood
How do dams support bodies of water? Scholars engage in a hands-on STEM activity where they design, build, and test dams to learn about bodies of water and how humans use natural resources. They learn how criteria and constraints affect...
LABScI
Cell Diffusion and Permeability: The See-Thru Egg Lab
Create a model to study a microscopic phenomenon. The seventh of 12 lessons uses an egg (without its shell) to represent a cell membrane. Using different solutions, learners explore the concept of cell diffusion. They monitor...
Virginia Department of Education
Permeability and Porosity
Covering both permeability and porosity, scholars perform a hands-on experiment testing various soil types. The material includes a pre-lesson worksheet to help focus pupils on the task at hand.
It's About Time
Oil and Gas Production
Would you consider a power failure a current event? This lesson uses multiple experiments, guided inquiry activities, and group discussions to cover the topics of oil and gas production. This is the seventh lesson in a series of eight.

Osmosis, Diffusion, and Active Transport
No, it really is okay to play with your food! Emerging scientists manipulate popcorn, eggs, and other household objects as they demonstrate multiple cellular processes. The activity, capable of modifications, is designed to reflect the...
Curated OER
Osmosis and Dialysis
How do you engage pupils in a discussion about osmosis without leaving them overwhelmed? By providing them with the tools to perform an exciting experiment, and they will see osmosis in action! Young chemists and biologists use a potato...
NASA
The Case of the Wacky Water Cycle
Join the tree house detectives in learning about the processes of the water cycle, water conservation, water treatment, and water as a limited resource.
Exploratorium
Bubble Suspension
Create a cushion of carbon dioxide gas to float some soap bubbles on. Many concepts can be demonstrated through this activity:
Carbon dioxide gas is more dense than air
Bubbles are semipermeable, allowing only carbon dioxide to diffuse...
Curated OER
Semipermeable Membranes and Bioaccumulation
Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....

Thirsty Rocks: Please "Porous" a Drink!
A simple activity goes a long way in demonstrating the property of porosity to your rock hounds. They will mass a specimen of dry sandstone and then soak it in a pre-measured amount of water. After seven minutes, they once again measure...

The Nobel Prize in Chemistry 2003 - Information for the Public
An information-packed eight-page article detailing the history of understanding active transport across cell membranes makes up the bulk of this handout. Two pages of reading comprehension and critical-thinking questions follow. The...
Curated OER
Is it Permeable?
The question is posed, is it permeable or impermeable, it's up to your critical thinkers to determine the answer. This presentation provides several scientific concepts related to permeability and the properties of matter alongside...
Curated OER
Runoff: Intro to Watersheds
Learners are taught that a watershed is, what types of basic land cover are impermeable and permeable to water. They trace the flow of water around their school and around their home. Students determine what watershed their school is a...

Chapter 3 ~ Physical Properties of Soil
Though information-packed, this presentation on soil is drab if it stands alone. As you journey through slides about soil texture, make sure to pass around samples of each type. Perform demonstrations as you lecture on soil density and...
Curated OER
The Membrane Potential
Give this summary of 16 pages of a text to your class to deepen understanding of cell permeability, diffusion, ions, and more. The handout portion includes vocabulary clarifications, detailed color diagrams, and important information;...
Curated OER
Soak it up
Students complete a hands on activity using hard boiled eggs, food coloring, tape, cups, water, and a knife to show how permeability affects animals. In this permeability lesson plan, students complete this activity and learn how...
Curated OER
Groundwater
In this groundwater worksheet, students use 12 given terms and match them to their definitions related to characteristics of groundwater and the components of the ground where the water travels. Students also fill in 5 blanks with given...
Curated OER
Porosity and Permeability Lab
In this porosity and permeability worksheet, students experiment with different types of soils such as sand, gravel, pebbled and rocks. They put each soil type in a beaker and pour water in being sure to measure the amount of water they...
Curated OER
Cells: Living Units
In this cell worksheet, students answer 81 questions about the cell including multiple choice, fill in the blank, short answer and matching. Topics include cell structure, the cell membrane, the nucleus, cell growth and reproduction and...
