How does a telescope magnify images? Learners first watch a tutorial explaining the basic construction of a telescope. Then they interact with a simulation that allows for changes in the location and diameter of the reflecting mirrors....

Students build a telescope and give quantification of its magnification and field of view while making observations regarding images. In this telescope lesson plan, students use a simple lens to project a scene and examine various...

Students explore the basic principles of the operation of the NASA's KAO telescope. They construct a simplified model of it using film canisters and other everyday objects. Step by step directions are included in plan.

Students construct a simple radio telescope. In this astronomy lesson, students explain how this telescope works and what information it collects.

Middle schoolers examine telescope construction. In this telescope instructional activity, students examine the lenses used in telescopes by exploring with convex and concave lenses.

Students complete night-sky observations to understand how our knowledge of the sky has been enhanced by telescopes. Students complete a timeline worksheet giving the history of telescopes. Students then then make their own observations...

Students interpret a message sent to space using a radio telescope and draw inferences from the interpreted message. Working with a partner, they interpret data that scientists believe is a message from aliens. They work on organizing...

Students examine constellations and planets through completing various activities. Students work individually and in groups to create drawings based on stars, compare and contrast the night sky with and without a telescope and learn...

Students assess how algebra, telescopes, space exploration and optics are so important in astronomy. They encounter studies on the Hubble Space Telescope, Hubble Deep Field and how algebra helps to determine the effects of contamination...

Students study the different telescopes and instruments used in the Observatory.  In this engineering and research lesson plan students explore telescopes using a website and build data tables about them.

Students make observations. In this sensory skills lesson, students use their senses as well as tools that sharpen their senses to make observations regarding foods and other items.

Students explore how telescopes work, build a model of their own, and consider how real telescopes can be used to ask-and help answer-questions about the universe.

Students examine telescopes and understand how they have helped us better understand the sky.  In this astronomy lesson students complete a worksheet and a lab activity.

Learners study pictures of space vehicles and make their own space vehicle. In this space vehicle lesson, students study pictures of the vehicles and compare and contrast the pictures. Learners classify the space crafts and then create...

Super science learners examine the sun's production of energy by the process of nuclear fusion. Hands-on activities make this lesson engaging for middle schoolers. The lesson is made up of four parts. Part I is an introduction to the sun...

Students analyze a microscope and study what they do.  In this investigative lesson plan students study how microscopes were first invented, and how ray diagrams are used in conjunction. 

High schoolers investigate the Law of Reflection and how light travels.  In this reflection activity students produce data from their experiment then create a pencil tracing.

Investigate the use of ratios in scale drawings. Learners scale objects up or down using ratios then find the actual size of something using ratios. They apply their knowledge of ratios as they make their own telescopes in science...

Students study comets and how Halley's comet was created.  In this space lesson students create their own comets using dry ice.    

Students observe chickens hatching in a classroom incubation environment In this egg-hatching lesson plan, students make observations of the hatching process and later care for the hatched chickens.

Geology beginners examine three different rock samples and determine their origin by their characteristics. By making and recording observations, they become familiar with features of igneous, metamorphic, and sedimentary rock types....

Students use scientific tools. In this Applied Science lesson, students investigate the use of scientific tools to enhance observation and discovery. Students indicate how each tool assists scientific work.

Students observe the brightness of stars and are introduced to the concept of apparent brightness as a measure of how much light hits a detector of a surface area during a given time. For this star lesson, students make connections...

Students investigate the force of gravity and how it effects different objects that are put into acceleration when applied the experiment of free falling. They drop different objects that have a variety of masses and some that cause air...
