Young scholars compare bacteria and viruses and their roles in biotechnology and bioterrorism. They outline fundamental steps of bacterial transformation and the possible selection processes to identify transformants. They discuss...

Students explore the effects of different density-dependent and density-independent factors on population growth. They explore how the interactions of organisms can affect population growth. Students explore the pattern of population...

Students know that participation in sports requires energy. They comprehend that we get energy form the foods that we eat and the air thta we breathe. Converting food and air into usable energy is defined as celluar respiration. Students...

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...

In this chemistry worksheet, students calculate the titrations of various types of chemistry problems. The questions include background information.

In this chemistry worksheet, learners examine the common characteristics of an acceptable graph that is meant to be used to display data.

High schoolers determine the molar mass of a gas. In this molar mass of a gas lesson plan, students use the vapor density of an organic solvent to determine its molar mass. They vaporize the solvent and collect the vapor. Once it is...

We know about the light spectrum, the age spectrum, and sound spectrum, but do chemical reactions also occur on a spectrum? Young scientists experiment with partial reactions on a spectrum and observe the color changes. Then, they...

Light a fire in your pupils! Scholars conduct a flame test and observe the emission spectra of several different salts in an enlightening hands-on investigation. They use their observations to make comparisons and conclusions about the...

If you use this as an outline for your chemistry lecture on metals, your young chemists will absorb a well-rounded overview. This is not a worksheet per se, but a useful summary of the behavior of metals. Save yourself some planning and...

Junior chemists manufacture biodiesel in the lab. In this exercise, they check the purity of the biodiesel using thin layer chromatography. They also calculate its density and heat of combustion. They are sure to rise to the...

To guide learners through observations of chemical samples in the lab, this resource asks them to give all formulas and complete the attached data sheet.  There are multiple questions about categories of elements and general...

Emerging chemists find their calling as they calculate the concentration of hydronium and hydroxide ions and the pH and pOH for several solutions. In some cases, values are given, and in others, actual word problems are written out....

Imagine being able to rotate the brain and view interior structures without dissection! This tool allows anatomy masters to do just that. They also learn about the associated functions, disorders, and symptoms of damage to each...

How exciting would it be for your chemistry class to produce their own "gold"? This experiment allows pupils to witness the chemical reaction of copper pennies as they react with zinc and sodium hydroxide to produce "gold" tokens. It is...

Why do some items feel colder when they are the same temperature? How should you keep your soda cold? What makes the wind blow? These are just some of the things middle schoolers discover when completing a lesson on...

Thirty percent of the world's oxygen is produced by rainforests found throughout the world. Seventh grade learners explore the processes of photosynthesis and respiration through 10 days of labs, manipulatives, and discussions. They...

Moving from its definition to how it moves and its different types, scholars see different examples and then move into its application and use in everyday lives, in an energy-based presentation.   

Substances with the same empirical and molecular formula must be differentiated by their structural formula. Part two in a series of 36 has pupils using chemical formulas to calculate how much of a compound is present in a given...

Classes continue their study of organic compounds in a detailed lesson covering alcohols, phenols, and ethers. Naming these compounds, classifying them, and describing their preparation and use are some of the topics covered. Through...

Amines are vital to humans because they help form amino acids, the building blocks of proteins. The 30th lesson in a series of 36 specifically focuses on the organic compounds that contain nitrogen. Learners classify amines and nitro...

Carbon, the base for all organic compounds, exists in nature in its purest form as graphite or diamonds. The 25th lesson in a series of 36 teaches pupils the nomenclature of organic compounds. Learners read about how to use the IUPAC...

Halogens comes from a Greek word which translates to make salt. Lesson 27 in the series of 36 teaches pupils about halogens. Pupils read, discuss, and answer questions in order to learn about haloalkanes and haloarenes. From defining...
