In this living things worksheet, students will brainstorm and fill in a graphic organizer focusing on the main idea of how living things compete. Then students will add four details to support their main idea.

Students examine how various countries meet or do not meet sustainability challenges. They read and discuss an article, complete an informational table, and participate in a group discussion.

Students examine mechanisms behind biological evolution and the theories that feed it, and are able to demonstrate their knowledge of these theories in a story.

Students demonstrate their knowledge of past, present and future pandemics. They create timeline for the spread of Influenza Pandemic of 1918. They discuss parallels between outbreaks of influenza and bird flu.

Students examine the issue of government versus private sector control of natural resources. They read an article, evaluate the need for international law governing resource allocation, and participate in a class debate.

Students use the scientific method to design a slow cooker.  In this experimental method lesson students measure temperatures and conversions of the solar cooker that they create.

Students experiment with mixtures of matter. In this matter lesson, students investigate which liquids form a solution when mixed together and which do not. Students also identify which solids can be separated from matter.

Young scholars experiment with solids and liquids. For this mixtures of matter lesson, students combine matter to form solutions. Young scholars hypothesize, test, and analyze the data to draw conclusions. The lesson can be extended by...

Students explore the amount of electricity used and wasted in homes and at school using kilowatt meters. In this environmental energy lesson, students compute power usage by appliances over time and identify ways in which...

Environmental explorers create an experiment related to ponds and then present their finding to the class. This resource is extremely open-ended. It needs more concrete objectives and procedures for meeting them.

Young scholars analyze the three models on the origin of troglobitic fauna. In this life science lesson, students also consider how the Zonation model explains the fauna's origin. They also use the Internet to research solutional and...

Students discuss the importance of California's water system. For this earth science lesson, student play the role of different stakeholders. They present a 2-3 minute argument on their group's perspective about their need for water.

Students experiment with a converging lens. They observe the image of an object through a lens. They determine the magnification of the lens.

Third graders study a healthy diet. In this healthy diet lesson, 3rd graders investigate the nutritional value of fruits and vegetables. Students compare a healthy diet to their personal diet.

You will need to go to the National Center for Biotechnology Information website to obtain the article, "In Katrina's Wake." Have your class read it and examine maps of where toxic chemicals were located in Louisiana at the time,...

Students investigate the physical structure of a protein by using a computer simulation tool. They record its primary amino acid structure while viewing it in three dimensions for a better visual recognition. There is also a comparison...

Students investigate the concept of succession and plant community dynamics. They play a game in order to conduct multiple experiments while playing. The interest of the game is useful for keeping student interest throughout the activity.

Pupils study the sun and how solar energy works. To learn about renewable energy, they complete a lab activity using a pizza box as a solar heater. Quite clever!
