Students describe an everyday situation which demonstrates Newton's Third Law. They state Newton's Third Law;"Every action has an equal and opposite re-action, or every force has an equal and opposite force" in their own words. ...

In this food additives activity, students will read information about the use of curing salt and ion nitrates to preserve food and the health problems that can occur from using these substances. Students will then answer 4 short answer...

In this atom instructional activity, learners read 5 paragraphs about ionic bonds. Students answer 2 true/false questions, 4 fill in the blank, 3 multiple choice, and 1 short answer question.

Learners identify patterns and relationships from data that is collected and solve variables.  In this investigative lesson students study ocean productivity, the nitrogen cycle and phytoplankton then answer questions.

Third graders act as scientists. In this property discovery lesson plan, 3rd graders explore the substance "Oobleck" (cornstarch, water, food coloring). They work in groups to investigate the substance and make observations as a...

Students discuss the steps of the water cycle. They create their own model of the water cycle. They complete the Family Page at the end of the instructional activity.

Students investigate how knowledge of science influences people in their daily lives, specifically in their careers. Students conduct interviews with an individual in a science or technology career as part of their research on the impact...

Middle schoolers identify ecological elements and their factors on species, populations and food webs. They analyze ecosystems for these elements and research how these factors influence species survival rate. Predictions on conditions...

In this science worksheet, students match each type of scientist listed in the left-had column to its correct description found in the right-hand column. There are 34 different scientists to match on the sheet.

In this endocrine system worksheet, students define 8 words associated with this human system. They answer 11 short answer questions about the structure and function of the organs and hormones that make up the endocrine system.

Students study and observe types of sea ice found in Alaska. In this sea ice lesson, students use the student network for observing weather to study the different types of sea ice. Students study sea ice depicted in Alaskan art.
