Students plant seeds in order to investigate and explore the questions: "How do seed companies develop varieties of plants?" and "What is the ideal plant?" Students will study related vocabulary and sketch seeds as they emerge. Students...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

Want my name and number? It's 6.0221415 times 10 to the 23rd, and my name is Avogadro. Providing nine different activities, experiments, and labs, this lesson keeps Avogadro relevant to your class all year long. 

In this molarity activity, students apply the definition of molarity to the given balanced equations. This activity has 4 problems to solve.

A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...

Young scholars 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.

Students analyze the calcium content of egg shells as an introduction to the toxic effects of pesticides on biological systems.

Using cabbage juice as a pH indicator, future scientists explore the effect of increasing carbon dioxide on the pH of the ocean and relate it to the health of coral reefs. Ideal for an earth or environmental sciences course, this...

Scholars learn about kinetics and buffers as they use qualitative and quantitative methods to understand enzyme rates and buffer capacity. The application of Beer's Law and spectrophotometry solidifies pupils' knowledge in the first of...

Five individuals in the class are "infected" with cholera! The rest of the class serves as investigators to discover the source of the outbreak. They test drinking fountains around campus for contamination. You, of course, will secretly...

Investigate the properties of rocks and minerals through a rockin' hands-on activity. Learners test rocks for various properties and, using a guide, attempt to identify different samples. They use various properties including hardness,...

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...

Use chemistry to change pennies into gold coins! The experimental procedure leads learners through the process of changing copper pennies to silver and then to gold. They record the mass of each coin through every step of the experiment.

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

In this chemistry worksheet, students write the structures for the compounds listed at the top of the sheet. Then they name the compounds whose structures are illustrated. Students also write the mechanism for the reaction of methyl...

In an electrolytic cell, electrical energy is converted into chemical energy, the exact opposite of a battery! Lesson 15 in a series of 36 explores electrochemistry. Participants begin by reading and discussing oxidation/reduction...

Pupils do hands-on activities and read information online in order to answer the central question of this lesson: How does understanding the chemistry of hair care, including the role of pH, help in the development of better hair-care...

Fourth graders are involved in a lab experience to look at the concept of heating up various materials to see how they react to an increase in temperature. They make observations and record them in a lab journal. Then students discuss...

Tenth graders participate in hands-on activities that require them to consider the implications of water pollution. In this environmental stewardship lesson, 10th graders conduct 6 experiments pertaining to water pollution and discuss...

Learners observe water samples and measure the samples' water quality. Learners develop their own criteria for measuring water quality and test for temperature, acidity, oxygen levels, turbidity, conductance, sediment and hardness.

In this chemistry worksheet, students take an exam that presents the concept of maintaining the ph balance. This can become a formal assessment.

As the title implies, this is a list of vocabulary terms relating to water monitoring. If your ecology class is learning about how to test water quality, this will be an appropriate reference sheet for them. As a bonus, if you live in...

Framed as an organic chemistry practice test, this resource could be used for a variety of purposes. Composed of 15 questions about organic compounds such as isomers, alkynes, alkenes and amines, and other topics related to organic...
