Fifth graders evaluate evidence that indicates a physical change has occurred. For this colonial living lesson, 5th graders explore the science involved in the making of items used in colonial life, such as, bread, butter, soap,...

Students explore climate changes. For this climate changes lesson, students research what causes changes. Students search the Internet, summarize reports they find and create a poster with the information.

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...

Students test pH of water before and after it travels through different substrates (igneous pebbles and limestone) to detemine how soluble materials can affect groundwater. They answer questions such as: What happended to the pH of the...

High schoolers investigate the physical, chemical and biological parameters necessary to establish an ecological baseline. Establishing an ecological baseline not only shows the ecological characteristics of a creek but makes the...

Tenth graders organize information to explain how photosynthetic bacteria contributed to climatic changes that happened on Earth. Students create a timeline by using a storyboard to tell the story of the change.

Ninth graders explore ways water moves through various reservoirs on Earth, examine how human activities change water cycle, investigate substances present in water that indicate human activity, and discuss how understanding water cycle...

High schoolers perform an experiment which will illustrate how to measure the approximate pH of chemicals in water using a pH indicator. They understand that a pH indicator is a chemical that changes color when it comes in contact with...

Students explore the Earth's crust by researching pH levels and acidity. In this environmental safety instructional activity, students identify the pros and cons of acidity within soil and how it affects plants. Students collaborate in a...

Students research emperor Justinian I in this lesson. They identify the contributions of Theodora to Justinian's rule, and the expansion of the Byzantine Empire during this time. They then analyze the contributions of Byzantine on...

Young scholars explain why dissolved oxygen is important in aquatic ecosystems. They evaluate the optimal dissolved oxygen levels for living organisms.

Students investigate the differences in chemistry between an acid and a base substance. They conduct measurements based upon the pH scale and then answer the questions included in the instructional activity. The information for the...

Ninth graders participate in classroom discussions, demonstrations and hands-on laboratory activities about pure substances and mixtures with a focus on common household materials. They investigate: What is a pure substance? What is a...

Students research microarrays on the internet in cooperative groups. Students write an essay describing the use of microarrays in environmental research and in medicine.

High schoolers explore conductivity and productivity in aquatic systems.
