Critter Crawlers Grade 4
Joanne Goelzer 2015

Grade Level:
4
Subject:
Science
Topic:
Motion and Energy
Objective:
To provide an exploration of motion, forces, and energy through the construction of a Critter Crawler and to practice measurement skills
Other Information:
NGSS Standards 3-5:

3-PS2-1. Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object
3-PS2-2. Make observations and/or measurements of an object’s motion to provide evidence that a pattern can be used to predict future motion
4-PS3-1. Use evidence to construct an explanation relating the speed of an object to the energy of that object.
4-PS3-4. Apply scientific ideas to design, test, and refine a device that converts energy from one form to another
3-5-ETS1-1. Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
3-5-ETS1-2. Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
3-5-ETS1-3. Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.

Crosscutting Relationships:

Energy can be transferred in various ways and between objects. (4-PS3-1),(4-PS3-2),(4-PS3-3)

Cause and effect relationships are routinely identified and used to explain change. (4-ESS3-1)
Prep:
Make sure that if using food cans that there are no sharp edges.
Use a pair of wire snips or scissors to remove the pointed end of the bamboo skewer.
Materials:
For each Critter you will need the following:

2 CDs You can also use paper plates, but they do not hold up to extended play.
1 soup can with both ends removed. You can also use toilet paper tubes
1 medium size rubber band
1 toothpick
1 bamboo skewer with the point trimmed
1 mint lifesaver or rounded sewing machine bobbin. I like the metal ones.
Masking tape
Bean Bag
