Relate Speed to Energy of Motion
Relate greater speed to motion energy for an unchanged cart and explain the comparison’s limits using a selected Washington Grade 4 science reference.
The Washington science directory identifies the Next Generation Science Standards and their three dimensions. This activity selects a reference from the OSPI-linked NGSS DCI arrangements, September 2017 edition. Check the school’s curriculum sequence and the complete chosen requirement. This activity selects a Grade 4 Washington science expectation. It is one part of a science course, not a complete curriculum.
The Washington science standards combine science and engineering practices, disciplinary core ideas, and crosscutting concepts. Connect all three dimensions when reading the complete performance expectation. Use the school’s course sequence to plan other investigations, models, and explanations. The general lesson library below may include review or enrichment beyond this grade’s course. This original activity is a focused starting point, not a complete curriculum crosswalk.
The same cart at two speeds
An invented observation record compares one cart moving slowly and then more quickly. The cart and its load are unchanged. Explain which case has more energy of motion. A second student introduces a different cart with an unspecified load; can the speed comparison alone settle its energy relative to the first cart?
Explain the evidence or model
The faster motion of the same unchanged cart corresponds to more energy of motion. Keeping the cart and load the same lets the comparison focus on speed. The first two records therefore support a qualitative explanation without an energy calculation. The different cart introduces a feature that the comparison has not controlled. Its unspecified load prevents a conclusion from speed alone about how its motion energy compares with the first cart’s. State the useful claim narrowly: for the same object, the faster case has more energy of motion. Do not turn it into a claim that every faster object has more motion energy than every slower object.
| Record | Object information | Motion |
|---|---|---|
| A | Original cart, same load | Slow |
| B | Original cart, same load | Faster than A |
| C | Different cart; load unspecified | Speed alone insufficient for this comparison |
What to check in the explanation
The speeds are described qualitatively, and no numerical energy values are supplied. This is a model record for discussion, not directions to race carts or cause collisions. The selected elementary expectation does not require calculating kinetic energy.
Plan the next activity
- Check that the cart and load stay unchanged.
- Explain how the speed comparison supports an energy comparison.
- Order the unchanged-cart records and leave the different cart unresolved.
Add a further record in which the original cart moves more slowly than both earlier cases with its load unchanged. Order the three cases by energy of motion and explain the condition that makes the comparison useful.

How does Grade 4 connect to Washington’s science assessment?
OSPI lists the Washington Comprehensive Assessment of Science (WCAS) in Grades 5, 8, and 11. Grade 4 is outside those listed general science testing grades. WA-AIM has separate participation guidance. Follow the school’s current directions and use classroom observations and explanations. Independently published practice has its own tools, timing, questions, and scoring; it is not an official state assessment. Read the official guidance.
Can speed alone compare the motion energy of any two objects?
No. This activity supports a speed comparison for the same unchanged cart. A different object or load needs additional information.
Where should I check the complete science requirements?
Read OSPI’s science page and the complete Washington grade or middle-school-band expectation, including the stated practices, core ideas, crosscutting concepts, and relevant engineering expectations. This activity covers one selected focus, not the complete course. Read the official guidance.
