# 03 Laboratory Ventilation and Risk Assessment Exercise
Students are introduced to the analysis of health risks in the laboratory, particularly from vapors from organic solvents. They consider quantitative measure of risk such as threshold limit values (TLVs), the amount of the compound that...

Solids, Liquids, and Gases
Not many lessons on states of matter can hold a candle to this one! Junior chemists gauge the density of paraffin in both liquid and solid phases. They fill 60 mL syringes with different materials to experiment with compressibility and...

Evidence of Heat Transformations
Earth, life, and physical science classes can all benefit from understanding heat transfer. There is not room enough to describe these seven exceptional laboratory experiments that explore conduction, convetcion, and radiation. Several...

Comparing Pulse Rates
Students participate in a lab that demonstrate one example of how the human body maintains homeostasis. Students collect data from themselves and observe how their own bodies react to exercise.

Understanding Probability Maps
What's the likelihood of your class understanding probability maps? Young scientists explore the concept using a virtual dartboard in an interesting simulation. The darts establish a pattern around the bull's-eye, which provides a visual...
Beyond Benign
PPM
The 15th lesson in the series of 24 helps your classes understand the ppm (part per million) unit of measure. First, scholars experiment with food coloring to determine concentrations before applying their findings to calculate...

Attractive Alloys
Include a lab about alloys and magnets in your fourth grade science lesson. Young scientists read the necessary background knowledge about alloys, then choose which objects (a screw, a bell, scissors, or coins) will be attracted to...

Can You Hear a Tree Fall in Space?
How does sound travel in space? Fifth graders investigate this question with a science activity, in which they research the properties of sound. Schedule a lab visit for individual Internet research, or include the activity after you...

Flower Power
Determine which plants are flowering plants with a helpful lab sheet. Kids first observe illustrations of different plants, such as a carnation and a fern, then decide which plants produce flowers, spores, or cones. Use magazine pictures...
Curated OER
Semipermeable Membranes and Bioaccumulation
Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....
Curated OER
Catalysts and Enzymes
Biochemists experiment with the oxothermic decomposition of hydrogen dioxide by adding manganese dioxide. They observe how pepsin enhances the action of acid on the digestion of egg white proteins. They use yeast to make bread rise. All...

Error/Uncertainty Analysis Worksheet for ___________________
This worksheet is meant to be used in laboratory experiments for which there is an accepted value that pupils are attempting to discover. It asks them to compare their results to commonly accepted values and then to calculate the percent...

Investigating What Makes Fruit Go Brown
Is there anything that can be done to slow the browning of fruit once it has been cut? High schoolers determine the answer through five different investigations involving apples, potatoes, and chemical reactions. After each experiment,...
Exploratorium
Thread the Needle
If you are setting up a rotation lab where learners are investigating vision at different stations, this activity can be used to explore depth perception. Setting up a giant needle eye, students attempt to pass a pencil through it with...

Energy from Water Wheels
Historians believe the first vertical water wheel was invented in Rome during the Augustan Age. The sixth lesson in the series of 10 has scholars experiment with designing their own water wheels. Through testing various pastas and...
Cornell University
Nano Interactions
Tiny particles can provide big learning opportunities! Middle school scientists explore the world of nanoparticles through reading, discussion, and experiment. Collaborative groups first apply nanotechnology to determine water...
