Want to hear a joke about sodium? Na. Young scientists test various materials to identify if they include protein, starch, and glucose by using the Biuret test, iodine starch test, and Benedict's test respectively. After practicing with...

Within the setting of a crime scene investigation, biochemistry beginners analyze organic compounds as a means of determining "Who dunnit." They use a brown paper test for lipids, glucose test strips and iodine to identify carbohydrates,...

We have all heard that we are what you eat, but what are we eating? An informative lesson opens with a discussion of the foods pupils have recently eaten. Then, young scientists perform four experiments on seven...

Your chemistry class set up six different redox reactions in the lab. Inquisitors methodically test each one and eventually order them according to oxidizing strength. This is a neat way to have the learners perform more than one...

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...

In this science worksheet, students add a few drops of iodine solution to each of 10 substances to determine if they contain starch. The iodine will turn blue if the item contains starch.

During a macromolecule lab, young chemists perform multiple tests, including iodine starch tests, to determine if eight mystery foods contain lipids, sugars, or starches.

For this mystery powder worksheet, learners determine the identify of 6 unknown samples by testing them with cabbage juice for pH, vinegar, iodine for starch and heat. Students determine the identity of the mystery powders using their...

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

In this digestive system worksheet, 9th graders identify and explain any difference found in color of the mixtures in two glasses. Then they determine what enzyme was produced by glands in the mouth changing the starch in a chewed cracker.

For this anatomy worksheet, students complete 22 review questions in the format of short answer, table completion, and fill in the blank after finishing an online virtual experiment about the chemical and physical processes of digestion.

In this diffusion through a membrane worksheet, high schoolers fill in the blanks to complete 27 statements about cell membranes, the movement of molecules across the cell membrane, concentration gradients and diffusion.
