In this science worksheet, students explore the learning outcomes for a unit on chemical reactions. Students define 60 vocabulary words and answer a list of questions for each topic.

Fifth graders study how respiration and circulation are connected.  In this respiratory lesson students complete several activities to better understand heart rate and carbon dioxide in the body. 

Tenth graders examine how energy is lost through different trophic levels.  In this trophism lesson plan students construct a food web and view a video. 

Students apply the ecological pyramids of numbers and biomass with an activity using topographic maps. In this trophic level instructional activity, students work in groups using a topographic map to determine the number of organisms...

Students recognize interdependence in a food web by using yarn and notecards to create a food web and discussing what would happen if one of the organisms from a certain trophic level is removed.

Students work in small groups to create a poster illustrating the flow of energy through a typical ecosystem, then present their posters to the class.

How much is your toaster costing you every day? Young environmentalists calculate the monetary costs of household appliances based on their average consumption of wattage.

Chemistry and earth science meet in a instructional activity 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...

Earth's atmosphere is full of different energies, from thermal to wind to electromagnetic radiation. Through the presentation, class members discover these energies and how they determine weather patterns.

Educate your learners on the importance of using bio-diesel as an alternative transportation fuel. Provided here are several links to books (with reviews), a 24-page informational text in three reading levels, a corn activity, and...

The feedback mechanisms of metabolism of a variety of substances in the human body. Carbohydrates, lipids, amino acids, and their derivatives are explained. The biochemistry required to explain the metabolic balance and feedback controls...

This is actually a 10-day mini unit on thermal energy for your high school chemists. Every avenue is taken to get learners absorbed in heat: a pretest, a PowerPoint presentation, Internet exploration, demonstrations, lab activities, and...

Students use satellite data to see the correlation between sea temperature and sunlight in the Gulf of Maine.  In this phytoplankton lesson students use Excel to analyze data. 

Have your class engage in lessons on earthquakes. Learners explore the science behind earthquakes using interactive websites and video clips. Then, they review the layers and parts of the Earth before delving into the causes of...

Students study erosion and its effects on shorelines. In this erosion lesson, students work in an engineering team to design a seawall and submit a cost bid to their teacher. Students must determine the energy of a wave and design a wall...

The principles of pollution control on a molecular level are summarised here. The reasoning and study behind the principles are described, and your class will undestand how some techniques are developed to be more efficient.

A more thorough presentation on coastal systems would be difficult to find! Detailed diagrams illuminate the offshore, shoreface, foreshore, and backshore zones of  beach. The sources and movement of sediments along the coastline...

Illuminated physics stars show what they know about light by taking this exam. They match several related vocabulary terms to descriptions and answer multiple choice questions about the characteristics of light, magnification, and...

How can you turn an ice cream activity into a scientific investigation? It's easy if you know ionic compounds, heat transfer, and the exothermic and endothermic process. Learners will explore the science behind freezing, insulation, and...

First year life science or biology pupils will appreciate this all-inclusive reference page. It provides a diagram of both a plant and an animal cell, the metric system prefixes, classification levels, definitions for cell processes, the...

New research proves even rinsing your mouth with carbohydrates without swallowing improves performance of the central nervous system. While some think sports drinks are amazing, others say they are a waste of money. Scholars learn about...

Dance is a fantastic way to communicate thoughts, feelings, and even science concepts. Make this activity a part of your next unit on weather and clouds. Kids will discuss types of clouds, how they look, and what they do. Then, they will...

The higher the number of letters in the final word for the National Spelling Bee, the higher the number of people killed by venomous spiders. Obviously, those two facts correlate, but no causation exists. Scholars view data based on...

The left hand rule, also known as Fleming's rule, is covered here with explanations and pictures to help undertanding. Examples of electric motors and generator use are given. A helpful set of slides which will help early physics...
