Students are given a history of electricity and its development into the modern age lifeline upon which we so depend. The methods of power generation are introduced, and further discussion of each technology's pros and cons follows. ...

First graders explore river rocks. Searching with screens and containers, 1st graders identify the different kinds and sizes of rocks. They separate rocks into containers according to pebbles, gravel and sand. Students write about their...

Students engineer new organisms using biotechnology. In small groups, they write procedures, list benefits and drawbacks, and explain how their new organism might affect the environment. After creating their new organisms, they present...

Pupils work together to investigate familiar and unfamiliar ecosystems. Using the internet, they discover how different organisms use their environment to satisfy their needs. They also examine the relationshiops between organisms and...

Learners review vegetables and their nutrient values and production. In this vegetable production worksheet, students read information about the nutrients in vegetables and how they are grown. Learners participate in a game of Twister to...

In this science worksheet, students answer 13 multiple-choice questions about mitosis and meiosis. For example, "Interphase is defined as..."

This instructional activity provides students with a lab experience during which students construct a basic electric circuit and use it to explore dexterity skills. A chance to construct and operate a tool that extends a person's...

Fifth graders work in small groups to brainstorm responses to a problem related to some disaster that wipes out half or all plant life on earth. Groups complete a graphic organizer to compare and contrast their ideas. Students select...

Students explore genetics, chromosomes and DNA.  In this genetics lesson students design a chromosome and identify a family tree through genetics. 

Eighth graders create and maintain a spreadsheet budget based on a predetermined salary. They have an opportunity to make "investments and purchases." Budget records be kept for an imaginary 4 month period.

Learners explore CCDs or Charge-Coupled Devices. For this digital devices lesson, students examine how CCDs are constructed, collect light, and create a digital signal.

In this science worksheet, students answer 14 questions about respiration. For example, "Cellular Respiration starts off with..."

Students visualize a communication system. They encode, decode, transmit, receive and store messages. Students use a code sheet and flashlight for this process. They will also maintain a storage sheet from which they can retrieve...

Students observe wild-oat seeds. In this biology lesson, students watch how wild-oat seeds react to moisture and draw conclusions and make predictions.

Students practice using a GPS receiver. They walk in different directions and monitor their progress on maps. They enter specific locations and use information given to them to get them back to their original locations.

Students examine how depth perception works through a class experiment. They design and perform their own experiment that investigates visual illusions.

Students discuss facts and myths associates with pregnancy and how conception can and cannot occur. They study fetal development and review terminology. They play a review game.

Students explore DNA structure using materials such as Twizzlers, small colored gumdrops and/or toothpicks.

Learners investigate how Global Positioning Systems work and how and why GPS receivers make errors. They graph data points and apply estimation and prediction to real-life GPS situations, discuss time delay, and complete a worksheet.

Learners compare the parts of a cell and their functions to their school to understand how a cell's parts work in unison to be effective in the body.

In this lesson, 5th graders will personify the parts of the cell physically and vocally.

Students look at the components of cells and their functions. The lesson focuses on the difference between prokaryotic and eukaryotic cells. Each part of the cell performs a specific function that is vital for the cell's survival....

For this lesson, 5th graders will examine cell diagrams, then use their body, voice, and movement to become a particular part of a cell. Next, they work in pairs to create a dialogue between the different parts of the cell, exploring...

Students learn about the different structures that comprise cell membranes, fulfilling part of the Research and Revise stages of the legacy cycle. Students view online animations of cell membrane dynamics (links provided). Then they...
