# 3rd Grade Science Lesson Plans

Time4Learning is an online student-paced learning system covering preschool through middle school. It is popular as a third grade homeschool curriculum, for afterschool enrichment, for remediation, and for summer study.

The lesson plans below provide a detailed list of the third grade science curriculum. The curriculum has been enhanced with material from Science4Us, a comprehensive, digital science program. Additional resources related to third grade science are also provided, below.

Students enrolled in third grade science will have access to second grade science lessons as part of their membership. Fourth grade science is also available upon request, so students can move ahead or review at their own pace.

If you are just learning about Time4Learning, we’d suggest first looking at our interactive lesson demos. Members often use this page as a resource for more detailed planning, to choose specific activities using the activity finder, or to compare our curriculum with state standards.

Total Activities: 8

#### Science Skills

Science Tools Review: The tools module reviews with students the tools scientists use for both qualitative and quantitative observations. Students review how to use tools such as their 5 senses, rulers, and balance scales through hands-on activities.

#### Force & Motion

Simple Machines: Students are fascinated with tools and machines, and will see examples of how simple machines can make work easier by reducing the force needed to move an object over a distance. Then, students will use interactive activities to experiment with these simple machines: lever, pulley, wheel and axle, wedge, screw, and inclined plane. Hands-on activities are also available to give students actual experience with simple machines. Force: When K-2 students study Force with Science4Us, they begin to think of force as a push or a pull. Students see examples of force on a playground through live videos and experiment with force through hands-on lessons. An interactive mini-golf game allows students to experiment with the effects of force as they decide how much force to use in hitting the ball. Finally, students explore factors and variables as they add what they’ve learned to their digital notebook. A special lesson on factors is included to help make teaching factors, controls, and variables easy.

#### Energy

Energy Transfer: Students learn about energy flow. They connect what they have learned about sound, heat, and light energy with new knowledge about energy transformations.

#### Balance in Nature

Eco Awareness: Students build directly from the knowledge they have gained about the natural world around them. Students learn that many factors affect whether or not living things can thrive in their habitats.

#### Earth

History of Earth: The Earth chapter begins with the History of Earth. Students learn about Earth’s long history and the place of exciting things like volcanoes, dinosaurs, and giant bugs within that history. Features: In Earth’s Features, students explore mountains, volcanoes, caves, rivers and oceans and their place on Earth. In one online activity, students guess which living things make their homes in Earth’s features.

#### Space

Exploring the Universe: Exploring the Universe begins with elements of space that we can see, like the sun and stars. In interactive online activities, students learn about the sun and stars and the Milky Way. Students learn to distinguish stars in the night sky from planets, airplanes or the International Space Station

### Lesson Activity Finder Tool

The lesson activity finder is one of the many helpful tools that Time4Learning offers its members. The activity finder is a shortcut that makes it easy for parents to preview lessons or find extra practice for their child.

Every lesson in the curriculum has a unique activity number, referred to in the lesson plans as an “LA Number.” These numbers can be found on either the scope and sequence pages or the lesson plans in the parent administration area.

The activity finder can be found in the lower left hand corner of the Student LaunchPad page. To use it, members simply log in to their child’s account, type the Learning Activity (LA) number of a lesson into the Activity Finder and click “Go” to open it.

For additional information, please visit our hints and help section, which gives more details about the activity finder.
