Osmosis - Moving Cellular Materials - STEAM Stations Lab - Cross Curricular Differentiated Life Science Lab Stations Students will use this stations lab series to learn about osmosis, diffusion, endocytosis, exocytosis, active and passive transport.With science as the primary background subject, stu
Your middle school or high school Biology students will love this lab! As they observe osmosis with eggs (and possibly potatoes), they will record their discoveries of how cells behave in hypertonic and hypotonic solutions using a student lab worksheet. Please note: This lab is also part of my Yea
If you are looking for a resource to help with the instruction and practice of active and passive transport look no further. This resource contains information on the following topics: - Passive Transport - Active Transport - Diffusion - Osmosis - Facilitated Diffusion - Concentration Gradient -
No unit on cell structure and function is complete without comprehensive lessons on cellular transport. Students need a solid understanding of osmosis, diffusion, concentration gradients, solute concentrations, hypertonic and hypotonic solutions, active and passive transport, etc. This lab, “Diffusi
This cell transport lab will give your students a hands-on and up-close view of osmosis, diffusion, and plasmolysis in living cells. This lab has two different activities. In the first part of this lab, the observation of plasmolysis in a living cell is a qualitative measurement. The student will
In this lab, students will watch through their microscopes as plasmolysis occurs in living cells. This lab will demonstrate to students how concentration gradients affect the movement of water across membranes. Osmosis, diffusion, and the concentration gradient become real to students as they obser
This lab uses an egg & various substances to model the importance of the cell membrane (allows molecules to enter and leave the cell as needed). It is a fun hands-on lab that provides an awesome model of a cell! Supplies you will need: *Eggs *Plastic Cups *Plastic Baggies *Vinegar *Corn (Karo)

This is a fun lab for students to explore the process of osmosis. They love this lab because they get to use Gummy Bears (or Gummy Worms if you like or both), even though they cannot eat them (I usually buy extra gummy bears so they can eat them the next day when they do their second observations) a
This lab packet contains 1 Skittles Diffusion Experiment and 1 Osmosis Gummy Bear Experiment. Both labs come with a list of materials needed, directions for setting it up, student data sheets to record their observations, and questions about each lab. The packet also includes quick wrap-up notes f
This hands-on diffusion and osmosis lab that is aligned with NGSS allows students to investigate and create a model on semipermeable membranes and watch diffusion and osmosis take place! Students will set up a dialysis tube with a glucose/starch solution into a beaker with iodine and water. This lab
In this activity, students use gummi bears to represent cells. They make qualitative and quantitative observations of the gummi bears prior to immersing them in different solutions. Later, they observe the changes in the gummi bears and complete discussion questions that link the lab concepts to osm
You will be able to conduct an experimental model that demonstrates your knowledge of the scientific method including, hypothesizing, data collection and graphical analysis, and reporting using appropriate metric measurements.• You will be able to demonstrate and describe knowledge of semi-permeable
Teach the process of osmosis to your Biology classes with these two student-centered labs with notes. Students start one lab, take notes while waiting for the results, and then finish with a second lab. This lesson takes one 40 minute class period with a few steps carried into the next couple of d
My students love to watch passive transport in action as, over the course of 3 days, a gummy bear massively expands and then contracts when placed in different substances. This activity does not take long. 15 minutes to gather data at the start of days 1, 2 and 3 and a little longer thereafter to a
Students use slices of potatoes to investigate Osmosis: the movement of water into and out of the cells of the potato. This lab focuses on making careful observations and collecting data such as weight and length. Students use a control to study changes caused during the experiment . By starting wi
How can we visualize molecular movement and correlate this with diffusion and osmosis? How does diffusion change with temperature? Once substances have diffused, do they ever separate? Students watch diffusion using food coloring and different temperatures of water. This is a great introductory lab
A. NEXT GENERATION SCIENCE STANDARDS HEREIN DCI’s: LS1.A Structure and Function Cross Cutting Concepts: Cause and Effect, Systems and System Models, Stability and Change Scientific and Engineering Practices: Asking Questions and Defining Problems Analyzing and Interpreting Data Developi
Students will observe the diffusion of a substance across a semi permeable membrane using starch and iodine. This low prep laboratory activity includes step by step instructions as well as an introduction, pre-lab observations, pre-lab questions, predictions, and post-lab analysis. You can also vi
This lab assumes you are using microscopes equipped with low, medium and high power lenses. Perfect for middle school biology and the study of plant cells. Elodea are a common aquatic plant that can be purchased cheaply at most pet stores that cell fish (sometimes stores will give it away for free
No unit on cell structure and function is complete without comprehensive lessons on cellular transport. Students need a solid understanding of osmosis, diffusion, concentration gradients, solute concentrations, hypertonic and hypotonic solutions, active and passive transport, etc. This classic lab
Students study the process of osmosis by placing gummy bears in water. Download includes lab handout with discussion questions, prompts for writing a conclusion, and criteria for writing a formal lab report. Enjoy!
How do substances move in and out of cells? Can any substance enter a cell or are some prevented from doing so? What happens when a cell loses or gains a significant amount of water? This lab uses deshelled eggs to investigate how water can enter and exit across their membranes. The idea of a contro
In this activity, students build a model to show molecular movement in solids, liquids, and gases and can use these models to show change of state such as melting, freezing, and evaporation. Using simple materials such as plastic pellets and plastic cups, students can design a series of models. By g
In this lab, students progress through Google Slides, watch videos showing the set-up and observe a time-lapse video showing the starch turning purple. This document can be shared over on Google Classroom or other LMS. A dialysis tube was used instead of a plastic bag because the process does occu
