High schoolers conduct an experiment using the reaction of hydrogen and oxygen. After pairs balance the chemical equation for making water, they mix different ratios of hydrogen and oxygen in a chemical reaction. Classmates...

After an explanatory introduction to sugars and enzyme activity, biochemists discover whether lactase is needed to digest lactose, sucrose, and milk as a whole. High school science lab skills are required for these investigations.

Biology classes will bubble with excitement as they complete this assignment. Beginning with an informative overview of cellular respiration and fermentation processes, the highlight comes as an experiment in determining the rate of...

Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...

Investigators collect the carbon dioxide produced when an antacid tablet is activated and identify what alteration produced the most gas. They also collect the gas in a buret in order to practice precision. Then they choose between two...

Advanced chemistry scholars read about gas chromatography as a means of separating mixtures into their components. Then they try the technique on fingernail polish remover. Detailed instructions are provided via a lab sheet for your...

Chemists consider a situation in which an ethanol producer needs to determine how much to add to t-butanol to prevent freezing during transport. They work in the laboratory to obtain the freezing point depression constant for the...

Students participate in a lecture and lab explaining the qualities of a casserole, identifying the different kinds, the function of the ingredients and foods used in the preparation of the casserole.

In this radish seed worksheet, students fill out a lab packet having to do with radish seeds. Students answer short answer questions, charts, and draw graphs of their results.

Students explore the predator-prey interactions and how humans have an impact on the food web.  In this food lab lesson plan students complete a food web activity and discuss what they learned. 

The intent of this series of activities is to introduce high schoolers to the field of chemical instrumentaiton. They perform a few basic chemistry lab techniques: pH titration, paper, gas, and liquid chromatography, ultraviolet and...

Advanced lab apprentices prepare zinc and copper solutions to which they will compare the same minerals from a multivitamin. Using absorption spectroscopy, they analyze the contents of the multivitamin for concentration. This lab can be...

As an example of nature's water filtering system, young ecologists conduct an experiment in the lab. They construct a funnel out of a plastic bottle, fill it with specified layers of materials that simulate layers of soil, then run muddy...

How would a pendulum work on the moon or Jupiter? To answer that question scholars control up to two pendulums including their location, length, mass, and amplitude. Added controls include changing the friction and strength of gravity....

As an anticipatory set, biologists listen to the story of Ruth Patrick, a scientist who used algae to detect water quality. They observe a demonstration of osmosis and diffusion. In their lab groups, they place Elodea stalks in...

Here is a full-fledged investigation of light waves, the electromagnetic spectrum, and element spectra. Physicists research a scientist that contributed to our understanding of the behavior of light. They take notes on your lecture, and...

Students who know what lab procedures are expected will work more effectively and be more successful during their lab experiences. See Preface Materials: Students decide upon lab partners and sign their names for each unit. Hand each...

Students review kitchen management, safety, and sanitation rules, and practice applying safety and sanitation rules in kitchen lab by preparing chicken stir-fry over rice while maintaining safe working environment. Students then complete...

Students investigate making esters in the lab. In this ester lesson plan, students mix 3 organic acids with 3 alcohols and a catalyst to form 3 different esters. Students identify the odors of each ester and write the formulas for the...

In this gas lab, students use a pressurized soda bottle with a closed end syringe to simulate Boyle's Law. They alter the volume and watch the effects on the pressure of the gas. They plot their data and answer eight post lab questions.

In this lab design and lab skills worksheet, learners answer questions about experimental design including finding variables, determining controls, and graphing data. They answer questions about microscopy and label the parts of a...

In this conductivity learning exercise, students answer post lab questions about substances that transferred electrons resulting in electricity flowing through the conductivity leads use to test each substance.

Students demonstrate intonation and their ability to discriminate between sharp and flat by responding to exercises within Auralia, and by creating their own examples for the class using the Tuning Function on the synthesizer. Requires a...

In this nutrient analysis lab learning exercise, students perform several experiments in a lab setting. Students test products for carbohydrates (monosaccharides and polysaccharides), proteins, lipids, and starches.
