This series of 3 hands on activities are designed to be a study of “magnetic interactions”.
It is also included in the Magnet Bundle of 3 lessons on TPT at:
Students ask questions to determine the cause and effect relationships when there are magnetic interactions between two objects not in contact with each other by conducting a series of activities aligned to the Next Generation Science Standards. The three dimensions addressed are (1) the scientific practice of asking questions; (2) the disciplinary core idea of types of interactions; and (3) the crosscutting concept of cause and effect.
NGSS 3-PS2-3. Ask questions to determine cause and effect relationships of electric or magnetic interactions between two objects not in contact with each other.
The first activity is an exploratory exercise intended to review, access prior knowledge, and build background knowledge. Students are presented with mystery envelopes and try to infer what is inside. Then a compass is introduced and students have more information to determine what is in the envelopes. In Powerful Poles, students use marked magnets to determine how magnets interact at the poles. They then use this knowledge to identify like and unlike poles of magnets that are unmarked. In this series, students have the opportunity to predict the outcome, conduct the activities, record the outcome, explain the cause and effect relationship, and finally ask another question to find out more about the phenomena. It is higher-level thinking at its best because it is interesting, inviting, and just plain fun.
Included in this document are: teacher background notes, teaching tips, rubrics for scoring, printable student recording sheets, science notes for reading, and vocabulary cards.
