Though it comprises only 5 percent of the world's population, the US generates 40 percent of the world's waste. Scholars learn about landfills, their safety, and other solid waste methods. They use experiments and research to learn more....

Students complete activities to study the properties of solids and liquids. In this states of matter lesson, students investigate the melting and freezing of a range of materials in a virtual experiment. Students melt the substances and...

First graders investigate how water can be both a liquid and a solid. They weigh popsicles and observe them as they write in their science journals. They measure the liquid as the popsicle melts and refreeze them to change them back...

First graders in kindergarten science class discuss matter. They make predictions and then identify mystery items in brown paper bags as either solid, liquid, or gas by using their senses. They discuss that a chemist is a scientist that...

Third graders research the Internet to locate geometric designs in familiar buildings. They review shapes, solids, angles and symmetry as they research websites of familiar buildings in Louisville. They record the information they see...

Students investigate and explore the three states of matter. They read and discuss the NASA article "The Engine That Does More," identify examples of each state of matter, and as a class complete a section of two worksheets. They...

Middle schoolers explore heat energy and how it is used to change the phase of matter, and discover that temperature does not increase or decrease until the phase change is complete. This extremely well-written plan is packed with great...

Students distinguish between three phases of matter: solid, liquid and gas, on the molecular level. They compare and predict the relative compressibility of the three phases of matter through journal writings and drawings.

Students investigate what matter is and how it changes states.  In this physical properties lesson, students examine the vocabulary database and identify the characteristics of the three phases of matter.  Students perform a...

Learners explore the six phase transitions between gases, liquids and solids for a variety of elements. Each group of students focuses on a different element, investigating its physical properties during each of the six phase transitions.

First graders are read a story about the various stages of matter with a focus on gases. Using a ziploc bag, they capture as much air as possible and discuss how it takes up space even though it is invisible. To end the lesson, they blow...

Learners explore geometry by completing a math worksheet in class. In this shape identification lesson, students identify the characteristics associated with 15 solid geometric shapes. Learners identify patterns between vertices, edges...

Learners demonstrate effects of waste on environment and ways of reducing it, observe how much packaging goes into bag lunches each day, and survey their families to assess awareness levels and household recycling practices. Lessons all...

Students explore liquids and solids by conducting in class experiments. In this matter lesson plan, students define the properties of matter and how heat can change those properties. Students experiment with heating objects such as...

Students create entries for the Architects of America contest, including a model of a futuristic structure, blueprints, a list of all plane and solid shapes in the structure, a persuasive argument paper that describes why the structure...

First graders identify various shapes in everyday objects. in pairs, 1st graders go on a shape field trip to locate various objects of different shapes. They photograph the objects and later use the prints to write sentences describing...

Students read a variety of letters from soliders who were on the front lines during World War II. After viewing an excerpt from "The War", they answer discussion and comprehension questions based on the letters and video. To end the...

Before one can understand the military tactics practiced throughout history, he needs to become familiarized with tactics practiced in the ancient past. Learners take a critical look at the military logistics used by Alexander the Great...

Take a look at the credibility of online sources such as Wikipedia. Discussion points and handouts are included to facilitate a meaningful and informative dialogue. Tips are given on how to determine if a Wikipedia article is reliable...

Get a global perspective and examine the challenges facing Mahmoud Abbas, the newly elected president of the Palestinian Authority. Thoughtful classroom citizens write letters to Mr. Abbas, asking him questions and suggesting advice....

Young scholars read The Greedy Triangle and discuss geometric solids. For this geometry lesson, students list the geo-solids in the world and create a graphic organizer to show where geo-solids exist.

The objectives in the resource allow students to explore the characteristics of simple solid shapes. Youngsters learn to recognize the face shapes, corners, and edges that make up 3-D figures by filling in a chart. Lastly,...

Third graders conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...

Students research an author and gather information that seems to support that person as author of The Night Before Christmas. They work in groups to gather the most solid evidence and they write a persuasive essay presenting their argument.
