Second graders investigate rice or gohan as it's called in Japan in a couple of experiments. They tally the results.

Fourth graders examine various types of rocks and record their properties. They collect rocks at home and bring them to school where they are mixed and distributed to groups of students. After writing their observations on...

Students explain how telescopes work and how they can contribute to our knowledge of the universe.

Young scholars examine the functions of earthworms and their effect on soil. They conduct an earthworm dissection lab, and complete a checklist.

Students estimate the extent of particulate air pollution present in their neighborhoods.

Students investigate how food, clothing and shelter come from soil after they examine soil from their own backyards. They map soils on the color wheel before making glue and soil pictures and tie-dying T-shirts in red soil.

Pupils identify, describe, count, tally, and graph life found in one square foot of land.

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 determine the temperature of the water in a cup, measure the length of a piece of cardboard, and measure out an appropriate volume of water. This task assesses student's abilities to perform measurement and reporting skills.

Fourth graders study census-taking. They participate in a variety of activities surrounding the U.S. census of 2000. They compare a modern census to one of 1905.

Students measure the lengths of provided leafs to the nearest millimeter. Students identify trends in the data as well as sourced of inaccuracy and formulate additional questions that could be investigated to enhance their understanding.

Students create a soil center on their school grounds. They begin to write in their science journals. They participate in an experiment that helps the community begin their own gardens.

Students experiment with graphing. In this graphing introduction lesson, students complete four activities: 1) a bar graph based on class birthdays 2) an estimation graph of the raisins in raisin bread 3) another estimation example with...

Students study estuaries and are able to define one, and describe its features.  In this investigative lesson students participate in an activity that shows them the importance of estuaries. 

Students discover how palaeontologists conduct a dig for fossils and how they interpret the age of the fossils. In small groups, they prepare a "dig site" consisting of bones, rocks and soil layered in a cardboard box. They switch boxes...

Students determine if human practices have any noticeable effects on the quality of stream life as measured by the presence of certain macroinvertebrates. They collect, preserve and identify macroinvertibrate samples and quantify the data.

Students make a pinhole viewer to demonstrate how it inverts light passing through it which produces inverted images.

Students investigate lenses and mirrors showing how they bend and reflect light waves.

First graders develop skills of scientific inquiry. They determine which objects float and which sink.

Pupils study the four layers of soil while identifying the substances that each level is composed up. They investigate the properties of soil such as color, texture, water retention and the ability to maintain life by growing a plant.

Students determine the size of a nanoparticle. In small groups, they calculate the actual size of a particle shown in a photo, and discuss how they arrived at their answers.

Students know the following parts of an egg as the yolk, white, shell, membrane, chalaza, and air sac. They also sequence the growth of the chick in the egg. An egg is broken and students touch, smell and see it. They locate the six...
