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.

What's on Your Plate?
Students demonstrate the path of food in the body. In this biology activity, students conduct an experiment to determine how large the the digestive system is. They name the different organs involved in the digestive process.

Investigation: Crazy Caterpillars
First graders explore biology patterns by creating a model insect. In this patterns lesson, 1st graders utilize snap cubes and pattern blocks to recreate their own version of a centipede or caterpillar. Students create their caterpillars...

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...

Gobble, Gobble and Gobble Some More?
Students are taught about stomach capacity and they reflect on how overeating might affect the body. They discuss the biological effects of binge eating by reading and discussing the article "Ate Too Much? Tight Pants May Be the...
Curated OER
Pollination
Students investigate pollination. In this plant biology lesson plan, 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...
Curated OER
Hypothermia on the High Seas
Students identify and present the effects on humans when the body temperature falls, demonstrate and explain how the body loses heat, and understand hypothermia and cold water survival techniques.

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...

Investigating the Behavior of Lumbriculus
Students perform a classroom experiment on the organisms of worms. They view the behaviors of the worms and analyze their results. This lesson introduces students to the techniques involved in behavioral studies.

Landforms in a Tub
Fifth graders use common household items to build landforms and simulate weathering and erosion.
Curated OER
Monopoly Graphs
Students relate the concepts of linear functions to the game of monopoly. For this algebra lesson, students solve problems with ratio and proportion. They collect data and graph it.
Curated OER
Enzymes
Tenth graders observe enzyme activity. They discuss the relationship between drug use and enzyme activity.
