Students explore reasons why the dinosaurs became extinct, and the specific needs (habitat, environment, food) of individual types of dinosaurs.

Fourth graders rank balls by size from smallest to largest and from lightest to heaviest and then by how much they made the water rise. They then discuss why certain balls make the water rise higher than do other balls.

Students role several balls of different weights down a ramp and into a paper cup and record how far each ball made the paper cup move. They then answer questions that help them analyze their results and reinforce the idea that energy...

Students investigate the motion of a swinging pendulum. They experiment with a pendulum to find out why it might swing at different speeds at different times.

Students compare the price and quality of different kinds of plastic kitchen wraps and then rank them from best to worst. They take into account how well it comes out of the roll, if it seals well, it is tangles, how much weight it...

Pupils listen to Chapter I, Chapter II, Chapter III, and Chapter IV of "The Forgetful Pony". They observe different stages of development of mealworms. The student sequences pictures to show the life cycle and draws the developmental...

Students observe that colored markers are a mixture of many different colors by performing a chromatography experiment. They make observations, record information, and make generalized inferences from their observations.

Students observe the motion of both a pendulum and a spring pendulum . They then explain the differences and the similarities between the two types of motions.

Students examine the properties of a liquid that contains water and food coloring and a liquid that contains water, food coloring and a liquid detergent. They interpret their data, describe properties, and make reasonable explanations...

Students design a chart to use to record the weather for five days. They then build an anemometer to record wind speed and discover why they are used for this purpose.

Fourth graders find the volume of cubes and cylinders. To determine volume, they fill large cubes with centimeter cubes. They discuss the formula used to find the volume of a cube. Students explore why the solution to the volume of a...

Learners collect evidence to make inferences about a object hidden inside a sealed box. They think critically and logically to raise questions. Students identify questions that can be answered through investigation. They formulate and...

Students analyze and discuss footprints and dinosaur tracks. They listen to books about paleontologists, create and analyze their own trackways using black paper and chalk, examine the data, and form hypotheses about footprints and...

Students demonstrate geometric relationships of finding area of rectangles and squares. They apply determine the quantity of paint needed to cover the area by using the concept of quantity.

Students classify rocks into groups after they observe the rocks and identify properties that can be used to divide them into groups. They then identify other properties that could be used to classify other objects into groups.

Students will make a circuit on a mystery card. They will connect wires, bulbs, and battery to form an electrical tester. After students learn how to make one following the directions, they can create their own mystery card by...

Students make a circuit on a mystery card. They then use an electrical tester to determine where electricity flows between circles on the card. They will connect wires, bulbs, and a battery to form an electrical tester.

Students test their knowledge of electrical conductors and circuits by constructing an electric tester and using it to determine where electricity flows between circles on a mystery card.

Students discover how inclined planes make work easier as they make mathematical predictions and prove their predictions through experiments.

Read about how Max and Ruthie measured some fun objects in their gym. Use this method to measure things in your classroom. A helpful teacher's guide and extra challenges will make this a fun instructional activity on measuring with...

[Free Registration/Login may be required to access all resource tools.] For this learning module, students are asked to measure the lengths, or heights, of objects in feet or yards. Includes video demonstrating a sample problem [0:25]...

A guide to support parents as they work with their students in ordering and comparing length measurements as numbers.

A guide to support parents as they work with their students in comparison of length, weight, capacity, and numbers to 10.

Activities where students take turns measuring their height, the width of parts of the hand, and the distance jumped using metric units.
