Fourth graders are divided into small groups and collect 4 objects from the playground. They take 5 to 10 minutes to classify their groups and discuss their findings including the terms "living" and "non-living". As a class they discuss...

Students create a dichotomous key to different varieties of potato chips. In small groups, they observe and record characteristics of the potato chips to use in the key. They switch keys with another group to see if they can identify an...

Ninth graders describe latitude and longitude and how they may be useful to find things on a map.  In this cartography lesson students divide into groups and devise a coordinate system that can be used to communicate a position. 

Students explore diagrammatic and taxonomic keys and their application in the marine sciences. They sort and classify objects and organisms based on visual attributes.

Learners explore the three states of matter. In this matter lesson, students are shown a variety of examples and decide whether it is a liquid, solid or gas. Learners brainstorm what characteristics the objects in each group share.

Students discover density.  In this density lesson, students discover the properties of objects that allow them to float or sink in water.

Fourth graders are introduced to a spring scale to show that the forces on both sides of the pulley are the same. They break into groups to lift objects with fixed pulleys and with multiple looped pulleys and then measure the force...

Students explore gravitational force. Through experimentation, students observe the acceleration of objects when they fall. They examine air resistance, and how the human body is attracted to the earth. Students discover the...

Third graders find the perimeter of a polygon. In this measurement lesson, 3rd graders use yardsticks to measure straight-lined objects to the nearest 1/2 inch. Student choose a "mystery object," find the perimeter, and record it on the...

Students explore and explain their connection to rivers through watersheds. They break into three groups. Each group needs: Blue enamel paint, Miniature objects to simulate a model river system, modeling clay, Tempera paint, Toothpicks...

Students investigate ratios of various objects.  For this ratios of various objects lesson, students draw pictures on graph paper and then dilate or shrink the image.  Students determine the ratio of their pictures. ...

Fifth graders explain why objects thrown upward falls back to Earth. In this earth science lesson, 5th graders identify the forces acting on objects. They discuss why planets do not float in space.

Young scholars practice their writing skills for describing place and location using prepositions. They find hidden objects and report to a recorder the exact directions for finding that object. Recorders write the directions.

Third graders investigate the concept of force and work. In this physics lesson, 3rd graders visit four stations which include pushing the wall with your hand, holding books for ten seconds, pushing a chair, and lifting a light object....

Learners give directions to help a classmate find an object. For this direction lesson, students tell the finder where to travel and how many steps to take. More difficult directions include angled turns.

Students explore types of motion. In this motion experiment, students observe how objects move. Students work in small groups to discover the laws of motion.

Students read the book We Can Do It! and discuss how we are all physically different. In this physically different lesson plan, students read the book, discuss their differences, and participate in a smelling and touching activity to see...

Young scholars explore electricity by completing Internet activities.  In this physical science lesson, students identify an electric circuit and describe the characteristics of conductors, giving examples as well.  Young...

Pupils explore the physical properties of matter. In this matter lesson, students collaborate as they participate in an activity that requires them to identify objects using their senses of sight and touch.

First graders distinguish between living and nonliving objects, and compare living organisms and nonliving objects.

Students view pictures of classmates' homes, make list of different objects in picture, and discuss what they can tell about place from evidence in picture. Students then observe artifact pictures, and read and complete artifact chart.

Students explore sampling with and without replacement. They explore the effects on the probability of drawing a desired object. Students examine probability and the difference between sampling with and without replacement.

Students are introduced to the power of magnets. In groups, they look at different objects and make predictions on whether they believe they are magnetic or not. They test their predictions and share their results with the class.

Students observe similarities and differences of natural objects. For this observation lesson, students use a magnifying glass to identify the details of objects.
