Scientists use morphological, physiological, and molecular information to continually revise organism classification. Scholars observe and learn about 20 shells. Then, they work to sort and classify the shells, building a taxonomy based...

Earth's surface constantly changes thanks to a variety of geological forces; in fact, Australia currently moves faster than GPS technology. Scholars connect the idea of continental drift to earthquakes and volcanoes with the help of an...

Watson and Crick built the first model of DNA in the 1950s, and our understanding of DNA since then continues to grow exponentially. Scholars learn about protein synthesis by observing a presentation and completing a worksheet. Both walk...

Genetic information transfers through nucleic acids, making these the chemical link that connects people to their parents and grandparents. Viewers determine the importance of both DNA and RNA after observing the presentation. Key...

The Hardy-Weinberg principle states that alleles and genotypes remain constant in the absence of evolutionary influences. Scholars complete a simple hands-on activity applying the Hardy-Weinberg principle to sample data. They observe how...

Reading the cues from nature can be as much an art as a science. The second installment in a six-part unit on climate teaches learners that environmental and biological events have significance. They first learn the difference between...

Many physicals include a blood glucose test, but what are doctors actually testing? Scholars graph and interpret blood glucose data, allowing them to observe the differences in lactase persistence and draw conclusions. They then connect...

Get an up-close look at energy transfer. Using a three-part activity, investigators first observe a teacher-led demonstration before building a model marble track to convert potential energy to kinetic energy. Scientists explore six...

A lot can change in a year! Investigators observe a video of Earth over the course of a year and complete a KWL chart. Astronomers view a second video, participate in a guided discussion, and discuss the rubric for successfully...

Elementary life science explorers compare and contrast aquatic and terrestrial plants (elodea and soybeans) in a Venn diagram. Some background information is provided to support direct instruction, and general instructions are provided...

Challenge your class with these physical science puzzlers, twisters, and teasers. Each individual responds to a series of riddle-style questions that are related to scientific terminology. While this has little educational value, it...

Students consider how topography affects weather and human activity. Students simulate a mountain range and observe surrounding wind patterns.

Students observe how to distinguish observations form inferences.  In this examining inferences lesson students list observations relating to the activity and discuss the importance of them. 

Students examine coral skeletons. In this science lesson, view real coral skeletons. Students explain the differences between an observation and an inference. Students draw a coral skeleton.

First graders practice observing items in small areas. In this scientific observation lesson, 1st graders complete a worksheet that shows a child looking at a small patch of grass. They make a list of items that the child sees. They...

Students explore magnification. In this scientific observation skills lesson, students observe sea life items and draw pictures of what they observe. Students predict which lens will have the strongest magnification when given three...

Learners compare poetry and the night sky. For this poetry lesson, students read poetry and compare the imagery from the poem with the night sky. Learners explore how science and poetry relate to one another.

In this science writing worksheet, students read about the details used in science writing such as facts, observations and conclusions. They answer 5 questions about paragraphs they read and they identify the differences between science...

Students explore magnification. In this science skills observation lesson, students make a hand lens using a wire loop and a small amount of water.

Students draw upon their prior knowledge of the density of water and practice writing a hypothesis, making an observation, and analyzing data while watching a density demonstration.

Sixth graders read about metamorphosis. They observe the metamorphosis of mealworms and set up the tables using Word processing to record their observations as the mealworms went through the stages of metamorphosis.

First graders observe a spider and write sentences about what they see the spider doing. In this writing lesson plan, 1st graders draw what they see, then make an edible spider out of marshmallows and twizzlers. A fun, delicious lesson...

Students play a biology game. In this science lesson plan, students play a game that require them to use observation skills and develop their classification skills.

First graders engage in this creative and well-designed lesson plan. They rotate through five learning stations, each devoted to one of the senses. They practice observation, experimentation, prediction, and categorization.
