Young scholars explore the concept of beneficial microorganisms. In this microorganisms lesson, students observe different bacteria found in organisms  Young scholars discuss and describe three ways that microorganisms benefit...

Learners mix solutions of polyvinyl alcohol and borax. They predict what happen and record their observations. They prepare a T-chart comparing Jell-o to their mixture.

In this anions learning exercise, high schoolers are given a table showing nine anions, the test that indicates the presence of each anion, and what will be observed when each substance is added to the anion.

Young scholars analyze the level of acid and base in a titration. In this chemistry lesson, students investigate the amount of acid and base required to create certain household chemicals. They perform this activity without the use of...

Students measure and graph the absorbance of light by chlorophyll at a specific wavelength versus chlorophyll concentration. They are given an unknown and determine its concentration from their calibration curve. Students become familiar...

In this chemistry worksheet, learners examine the concept of thermodynamic equilibrium constants with intense detail. The application of the knowledge is practiced with problem solving.

Students collect data on causes of Acid Rain. In this science lesson, students simulate the effects that produce acid rain, collect and analyze data from their samples. They relate science and statistics in this lesson.  

Young scholars explore density by floating golf balls. They explore having their golf balls float halfway in a container of water and discuss density and its realtionship to where the golf balls are floating. After adding food coloring,...

High schoolers determine the equilibrium constant for a chemical system and use graphing techniques and data analysis to evaluate experimental data.

Young scholars will first extract genomic DNA from spinach and perform a restriction enzyme digestion on both the spinach DNA and the plasmid using the same restriction enzyme. They then ligate the cut plasmid DNA with the cut spinach...

In this acid-base reaction worksheet, students balance reaction equations when acids and bases are mixed then calculate the pH of the solution. There are 2 questions with a total of 18 parts.

In this chemistry activity, students complete 15 short answer questions and problems on empirical and molecular formula, naming and writing chemical formula of compounds.

In this acid-base reaction worksheet, students calculate the ion concentration and pH for 6 solutions, graph titration results for 11 reactions and use Henderson-Hasselbach equations for three problems.

Students recognize whether a solution is an acid or a base. In this acids and bases lesson plan, students use chemicals and identify if those chemicals are acids or bases. From the conclusion, students will be able to identify if the...

High schoolers 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...

Students become aware of the environmental problems caused by acid rain and study the pH scale. They determine acidity of local rain water.

Students view a video that presents how viruses attack the body and how the body's immune system responds. They simulate the spread of an infectious disease and establish the identity of the original carrier.

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.

Young scholars conduct an experiment to test the reactivity of metals and non-metals. In this chemistry lesson students test metals with different chemicals to observe the reaction. The results are used to categorize the metals.
