In this electrochemistry worksheet, students solve 9 problems such as identifying masses of metals produced at cathodes, determining the potential of a cell's electrode and writing cell reactions along with their potential.

In this living environment worksheet, students answer a variety of questions about living organisms, the processes they go through to make food and break down food, absorb nutrients, and release toxins. They explain homeostasis, they...

Students research solar energy. For this solar energy lesson, students construct a KWL chart and research solar energy through various websites and related readings. Students complete a science journal page as an assessment.

Students apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...

Learners brainstorm a list of electrical devices used in their home. They read an article about electricity usage in a heat wave. In groups, they create public service announcements promoting energy conservation. They share their ideas...

In this cellular energy worksheet, learners review the stages of cellular respiration and contrast fermentation with cellular respiration. This worksheet has 6 fill in the blank and 6 short answer questions.

The climate at the equator is hotter than the climate at the poles, but why? The lesson goes in depth, explaining how the angles of illumination relate to the heating rate at different latitudes and seasons. Scholars use a strong lamp,...

There is a specific zone, or distance from a star, that a planet must be in order to have water in a liquid form. The activity demonstrates how flux density depends on its distance from the source. A photovoltaic cell gets power to...

Every region has a renewable resource that can be used to make hydrogen. But, what is hydrogen and why can it be used as an energy source? Find out with a presentation that answers these questions and then discusses where hydrogen is...

Just because we can't see it doesn't mean it isn't there! A growing concern for environmental scientists is toxic nanoparticles in our air and water. Young scholars conduct an experiment to demonstrate how these particles can cross our...

Active and passive systems used to transport materials to and from cells are the subject of a comprehension worksheet that asks readers to use information from the article to answer a series of questions based on the text.

Young scientists are introduced to the connections among cells, tissues, organs, and systems in a life science reading comprehension worksheet that asks them to respond to a series of questions based on the passage.

Don't be shocked when your class has a blast making their own batteries! Science scholars examine a dry cell battery, then design and construct a wet cell battery. The activity guides them through the parts of a battery, the variables...

Chemistry and earth science meet in a lesson on carbon dioxide emissions. After reading about atmospheric problems caused by using fossil fuels, science stars balance equations for the burning of different alkanes. They compute the...

How does one organism get its energy? What is the main source of energy in an ecosystem? How does the flow of energy affect different types of ecosystems? Answer these questions with a fill-in-the-blank instructional...

Following detailed directions, teams collect the voltage and current outputs of a photovoltaic cell by adjusting the resistance. Using the collected data, they determine the highest power output. Implications for weather and a large...

Learners investigate energy using a photovoltaic cell. In this electricity lesson plan, students collect data from current-voltage and power-voltage curves to determine if photovoltaic systems have an advantage over conventional electric...

This exam touches upon every topic within the typical first year biology course.. A broad variety of question styles give high schoolers every opportunity to show what they know. Why start from scratch when a comprehensive final exam is...

The National Chemistry Olympiad exams are comprehensive tests covering an entire  year of chemistry concepts. You can use them as practice for competing in the challenge, or simply as a review, or as an actual final exam for your...

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on an entire year's curriculum when they take this thirteen page test. 

Students show the relationship between the need for plants to undergo photosynthesis in order to generate oxygen. They see the flaws associated with this thinking because of the lack of CO2 and H2O and lack of sufficient gravity in order...

Students research on renewable and nonrenewable resources. For this chemistry lesson, students design and build solar panels. They evaluate their device and write a lab report.

Learners discuss the process of photosynthesis in plants and that oxygen is produced as a by product. They observe underwater Elodea plants "breathing" in a hands-on activity. After setting up the experiment, they observe the plant for...
