Human Reproductive Cells Quiz
Quiz your learners on human reproductive cells using this terminology assessment tool! Choose 1 of 2 options: have students play online, or make copies of the paper version. The advantage to playing the online matching game is its...
Cold Spring Harbor Laboratory
Development Balances Cell Growth and Death
Cells demonstrate a life cycle like other living things, but what if death was no longer part of the cycle? Learn about the important balance requiring death to continue functioning. An online interactive introduces a group of scientists...
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...

Osmosis and the Cell Membrane-part 2
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...
PBS
The Egg
The first stage in the butterfly's life cycle is the egg. Young entomologists discuss why different butterflies lay different eggs and what their eggs look like. Then they use the handouts to make a replica of one type of butterfly egg...
Curated OER
Structure and Function of the Cell/Introduction to the Cell
So, this is not technically a worksheet, but rather a chapter of reading material, pictures, and diagrams introducing young biologists to the cell. Cell theory, diversity, size, and shape are described. The internal organization and...

Rubber Egg
Students demonstrate the semi-permeability of a cell membrane. In this rubber egg lesson, students measure and record egg data, place the egg in jar with vinegar and close the lid, observe immediately and periodically for the next 3...
Curated OER
The Day an Egg Solved the Mystery of the Cell
Students conduct an experiment comparing human cells to chicken cells. In this cells lesson plan, students conduct an experiment to see how nutrition moves through cells and how to better take care of their bodies.
Curated OER
Observing Osmosis
Students investigate osmosis using egg cells with the shells removed. In this osmosis lesson plan, students remove the shell of an egg by letting it soak in vinegar for two days. They take measurements and observe the cell. They soak the...

Egg Toss
This cross curricular lesson involves eggs. Students read about eggs. A counting game involving an egg carton and ping pong balls (eggs) is played as students toss balls into numbered egg carton cups and adding their score. Students...
Curated OER
Tower Investigation and the Egg
Students build three types of towers, engineering them to hold an egg one foot high for 15 seconds. They discover that engineering designs are subject to constraints such as time, money and size specifications. In this activity students...
Curated OER
EggCELLent Diffusion
Students examine and discuss the concepts of diffusion and osmosis. They observe the effects of diffusion on eggs by recording the change in an egg's size and the amount of liquid substance that remains.
Curated OER
Create a Microbe
Students construct models of microorganisms recognizing size relationships-comparing the size of viruses with the sizes of bacterial and eukaryotic cells. They put into perspective just how small microbes are by comparing the size of...
Curated OER
Osmosis
Students explore diffusion and active transport. They observe the effects of eggs in vinegar and predict what will happen when eggs are placed in corn syrup with food coloring. Students complete worksheets which lead them to describe...
Curated OER
Karyotype Puzzle
Students identify chromosome pairs based upon band patterns and location of centromere. They order chromosome pairs based upon size. Students differentiate normal karyotypes from abnormal karyotypes. They correctly record karyotype...
Curated OER
Create a microbe
Learners explore viruses and bacteria. They construct three dimensional models of microorganisms recognizing size relationships by comparing the size of viruses with the sizes of bacterial cells.
