Labs

The "Burning Peanuts Laboratory"

reveals the energy stored in food and includes a student guide

.

The "Effects of a Closed Environment on Living Things" lab demonstrates how plants use carbon dioxide and produce carbon and how animals use oxygen and produce carbon dioxide.

This "Do Plants Consume or Release CO2? Or Both?" lab demonstrates how plants carry on both photosynthesis and respiration.

The "Rate of Photosynthesis" lab explores just that.

Do the "Leaf Pigment Chromatography" lab

.

This lab

compares the production of starch in leaves kept in the light and those in the dark.

This "Fermentation by Yeast" lab

can be used in this unit or with the study of microorganisms. This is an image of the lab report for this lab done by one student group.

"Photosynthesis: A Controlled Experiment" illustrates the effect of differing amounts of carbon dioxide on photosynthesis in geranium plants. Coleus or other similar plants could just as easily be used.

"The Energy Content of Food Laboratory"

is another activity for determining the calories in food and includes a teacher's guide

.

In "The Heat is On - The Energy Stored in Food" students will burn several types of nuts and snack foods in order to determine their heat content per gram.

In Kim Rebello's "Every Breath You Take"

lab students investigate whether animals and plants carry on respiration.

Make a homemade calorimeter to determine "The Energy in Food"

.

This "Waterweed Simulation" is a worksheet to acompany "The Waterweed Simulator." Students count the bubbles released by Elodea to determine which color of light is more effective for photosynthesis. (Since Elodea is hard to come by these days, this is a good alternative.)

This "Plant Respiration" lab

uses seedlings and a bromothymol blue solution to demonstrate that plants give off CO2 during respiration.

In "Studying the Effect of Photosynthesis and Respiration on Aquatic Chemistry" students use microcosms and RUSS data to investigate changes in oxygen concentrations that result from photosynthesis and respiration. The lab includes a worksheet.
