Energy and Waves | 8 Lessons, Case Cards & a Project | Grade 4

Energy and Waves is a science unit for Grade 4 with 33 pages of classroom material and a separate 13-page teacher guide. Students connect energy to observable change, compare speeds, study collisions and design, follow energy pathways, and describe wave patterns, amplitude and wavelength. It is written for fourth grade teachers who want a self-contained NGSS-style unit with explanations, supported practice and reasoning cases.

The unit has eight lessons with the same three pages each: an explanation page, a practice page with explanation, and a case card. The first three lessons start from observable change, speed and collisions. Lessons 4 to 6 follow energy pathways and then waves, with one lesson on amplitude and wavelength. Lesson 7 looks at information codes, and Lesson 8 uses claim, evidence, reasoning. A page of wave model diagrams, two vocabulary pages, a learning check and a short project with a reflection page complete the unit.

What's Included

• Classroom Material: 33 pages (PDF, print edition)
• Teacher Guide: 13 pages (PDF) with answers, case guidance and assessment feedback
• Editable DOCX text editions of the classroom material and the teacher guide
• Presentation with 17 slides (PPTX)
• Original illustrations and model diagrams; the PDF is the print reference and DOCX line breaks may differ
• A page of wave model diagrams

The 8 Lessons

• Lesson 1: Energy and observable change – Linking energy to changes students can observe.
• Lesson 2: Speed comparisons – Comparing how fast things move.
• Lesson 3: Collisions and design – Looking at collisions and how design responds to them.
• Lesson 4: Energy pathways – Following how energy moves from place to place.
• Lesson 5: Wave patterns – Describing the patterns waves make.
• Lesson 6: Amplitude and wavelength – Comparing amplitude and wavelength.
• Lesson 7: Information codes – Looking at how patterns can carry information.
• Lesson 8: Claim, evidence, reasoning – Supporting a claim with evidence and reasoning.

Students Will Learn To

• Connect energy to changes they can observe
• Compare speeds and describe what happens in a collision
• Follow the pathway energy takes in a system
• Describe wave patterns and compare amplitude and wavelength
• Support a claim with evidence and reasoning

Perfect For

• Grade 4 science teachers who need a closed unit on energy and waves
• Teachers who want students to argue from evidence rather than memorize terms
• Classes that need a clear sequence from energy to waves to information codes
• Homeschool families looking for printable lessons with a separate answer guide
• UK and Australia: roughly Year 5

Why Teachers Choose This Unit

• Each lesson follows the same explanation, practice and case card pattern, so students know what to expect
• A page of wave model diagrams helps students compare amplitude and wavelength
• The closing claim, evidence, reasoning lesson gives students a structure for explaining what they found
• The teacher guide has a teaching concept, sequence and preparation notes, answers for all eight lessons, an assessment key with feedback, and a differentiation and observation chapter
• Editable DOCX text editions allow you to adapt wording for your class

Frequently Asked Questions

Which standards does this fit?

The content is closest to NGSS 4-PS3 (energy) and 4-PS4 (waves and information). No alignment or endorsement is claimed.

Are answers included?

Yes. The separate 13-page teacher guide has answers and teaching notes for all eight lessons and an assessment key with feedback.

How long does the unit take?

The material does not state a duration. Plan by lesson: each has three pages, and you can use the lessons in order or choose the ones you need.

What is covered about waves?

Lessons 5 and 6 cover wave patterns and the difference between amplitude and wavelength, supported by a page of wave model diagrams. Lesson 7 turns to information codes.
