In this activity, students will study the moon for a period of one month and learn to identify each major moon phase. They will then describe the moon through poems, haikus, and similes.

In this lesson, students use their bodies to model the day/night cycles of the Sun and Earth. Next, they discuss the moon's role in the solar system and explore the eight phases of the moon by acting out a story. Finally, a song brings it all together to deepen the learning.

With the help of videos and photos, students conduct open-ended scientific investigations to discover how gravity and microgravity affect the life cycle and web design of orb-weaver spiders on the International Space Station.

Variables allow for a lot of freedom in computer science. This lesson helps to explain what variables are and how we can use them in many different ways. [1:43]

A video lesson over viewing how to construct a hypothesis explaining the guidelines that need to be followed. Understand that a hypothesis must be logical, account for relevant information, be testable, and be in the simplest form. [2:21]

Isabella and Amalie are in Copenhagen, and they saw a periscope in the water. Join them, and find out what this is all about. This module discusses how to use a periscope, what light sources are, and how light impacts shadows.

In this lesson, students learn that light travels in a straight line from a light source and that ray diagrams help us understand how an image will be created by a lens. In the accompanying activity, students explore the concepts behind the workings of a pinhole camera.

Play a game of concentration by matching terms used in the scientific method to their proper description.

This content package is a curated collection of STEM instructional resources to support the introduction and exploration of programming and robotics in grades 3-5. Resources include lesson plans, engagement activities, ebooks, digital texts, and videos.
