Mitosis Flip Books (T. Tomm, Havana Inferior Loftier, Havana, IL)
Targeted Concepts:  Mitosis, jail cell partitioning, organelles and their functions

This project (passed down to me from a fellow teacher) is based on the one-time cartoon flip book idea. Students use template cards (printed on encompass stock or glued to index cards) to create a booklet that illustrates the steps involved in jail cell division. After reviewing the stages in cell division (see the Mitosis Note page below), I provide a set of templates (see Mitosis Book below) for them to use to make a flip book. From stage to stage, they must draw diagrams to show the changes that occur throughout the process. I encourage "colour coding" to make the end upshot easy to follow. Once all the Pages are completed and in the correct order, students use a heavy duty stapler to bind them together. They can flip through the pages and "run into" mitosis in action.

Egg-cellent Ideas for Osmosis and Diffusion (Submitted by Sue Remshak, Lake Bluff Middle School, Lake Barefaced, IL)
Targeted Concepts:  Cell processes, osmosis, diffustion, scientific discipline process skills (observations, hypothesis, information collection, analysis)

During this activity students investigate the concepts of osmosis and diffusion using eggs. To prepare for the activity, have students carefully mensurate and record the circumference of the raw egg every bit well as its mass. Place the egg in a chalice filled with white vinegar and allow fourth dimension for students to tape their observations. Shop the eggs in a fridge for 24 hours. Allow time for students to record their observations. Render the egg to the refrigerator for some other 24 hours. After 48 hours have elapsed, observe the egg's appearance. Students should carefully remove the egg from the beaker and record its measurements. Allow time for students to write an explanation of their observations using the correct vocabulary.

Instructor Info : A chemical reaction occurs between the vinegar and the calcium carbonate in the egg shell. The bubbles of carbon dioxide that form on the egg and rising to the surface are testify of this reaction. The shell dissolves in the vinegar and leaves a movie on the surface of the vinegar. All the same, the membrane remains on the egg. The size of the egg increases considering of the movement of water in the vinegar through the cell membrane. Since h2o moves from an area of loftier concentration to an area of low concentration, this process is called osmosis. Obviously, none of the materials on the within of the egg are able to laissez passer through the membrane.

For the second portion of the activity, yous will demand plain water, blue water (food coloring in h2o), molasses, and corn syrup. Start, accept the students determine the mass of the egg and tape it in the table. They should cascade 150 ml of each substance into its ain chalice. Add the eggs and store in a fridge for 24 hours. After 24 hours, accept the students remove the eggs from the beakers and record their observations. Students should record the volume of liquid in the beaker every bit well as the mass of the egg. Finally, have the students employ a toothpick to pop the egg membrane and record their observations. Exist certain to have paper towels handy every bit some eggs may squirt!) Allow time for students to write an explanation of their observations using the correct vocabulary.
Teacher Info: The egg in apparently h2o and blue water will become slightly larger because h2o will laissez passer into egg through the membrane by the process of osmosis. There will be blue food coloring in the egg from the blue water since both water and food coloring tin laissez passer through the membrane. The egg in corn syrup and molasses will decrease in size because water from inside the egg flow through the membrane into the syrup or molasses. It moves from a higher concentration inside the egg to a lower concentration in the corn syrup. Once once more, this is called osmosis. The corn syrup and molasses molecules are too large to pass through the membrane. Observant students will not simply notice an increase of book in the beaker, only they will likewise see a thin layer of water resting on top of the syrup and molasses.

To illustrate the concept of diffusion, add a drop or two of extract (vanilla, bubble gum, lemon, or cinnamon) into a deflated airship. Blow upwards the airship, tie it off, and place inside a shoe box. To brand sure the hat stays on the box, use masking tape to secure it. During grade, ask students to life 1 finish of the shoe box lid and smell the contents. Their eyes should remain closed when they do this. Ask each student to reveal what they smelled. Testify the class what was within the box and instruct them to draw a film and record their observations. Challenge students to write an explanation (using the correct vocabulary) of why the box smells similar the scent when it was only put inside the balloon.
Teacher Info : The shoe box smelled of the scent even though it was merely placed on the within of the balloon due to the process of improvidence. Every balloon has microscopic holes in its surface. The vapors were able to laissez passer through the membrane from an surface area of loftier concentration to an area of low concentration. Nevertheless, the liquid scent molecules were too large to pass through the membrane.

Another fashion to illustrate osmosis and diffusion is using a tea bag and some water. During class, place a tea bag in a chalice of warm h2o. Allow time for students to tape their observations. Claiming them to write an explanation using the correct vocabulary.
Instructor Info : Water flows by osmosis into the tea purse. The students tin run across this if you remove the tea bag from the chalice and squeeze information technology to encounter the water come up out. The tea leaves diffuse through the tea bag and into the water; this changes both the color and flavor of the h2o in the chalice.
