Effect of Size on Uptake by Diffusion
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...

TE Activity: The Boxes Go Mobile
Students create a mobile of boxes and cubes that they made in a previous lesson that can be accessed from this page. They design the mobile using method that an engineer would use to balance the items based on surface areas and volumes.
Curated OER
Cell Reproduction
In this cell reproduction worksheet, students will discover that when a cube doubles in size, the surface area grows by four times and the volume grows by eight times. Students will use this information to understand the limits to cell...

How Much Energy Is There in Food?
People associate calories with food, but what is a calorie? Young scientists measure the number of calories in samples of food to better understand the concept. They test a variety of samples, take measurements, and compare their results...

Changing the Freezing Point of Water with Salt
First graders explore freezing points. In this science lesson plan, 1st graders determine the temperature at which water freezes, understand why salt water freezes at a lower temperature than plain water, and understand why the string...

Pollination
Learners investigate pollination. In this plant biology lesson, students study a diagram of the reproductive parts of the flower and dissect and identify the parts of a real flower.
Curated OER
Chancing it
Seventh graders examine different transplant types and estimate the possible outcomes. In this biology lesson students discuss donors and transplants then divide into groups and complete a worksheet.
Curated OER
New Boxes from Old
Ninth graders take a rectangular box (e.g., a cereal box) and cut it up to make a new, cubical box with the same volume as the original. In so doing, they will discover that because the cubical box has less surface area than the...

Why Are Cells So Small?
Students examine the relationship between cell surface area and the ability of materials to diffuse through a cell. They participate in an experiment in which they determine which materials diffuse easier than others. They complete...
