Sledding Hill
In this provocation, students will design a sled and a hill for the sled to move down. They will explore making the sled go faster and slower.
Objective:
-
Can you design a sled and sledding hill using these materials?
-
How will your sled move? Can you make it move faster or slower?
Problem-solving and strategic thinking:
-
Students will use materials provided to build a sled
-
Students will label and/or create signs to identify roads and buildings
Standards/Objectives addressed:
-
K-PS2-1. Plan and conduct and investigation to compare the effects of different strengths or directions of pushes and pulls on the motion of an object.
-
K-PS2-2. Analyze data to determine if a design solution works as intended to change the speed or direction of an object with a push or pull. (see K-2-ETS1-3)
-
K-2-ETS1-2 Develop a simple sketch, drawing or model to illustrate how the shape of an object helps it function as needed to solve a given problem
Background knowledge needed:
-
How to make a plan - sketch a design
-
Understanding of sleds and slopes/hills
Materials:
-
Bottle caps, aluminum foil, wax paper, cardboard, tape/duct tape, glue, string/yarn, blocks, bear counters or other small characters to ride the sled.
Prompts – questions or statements to elicit engagement:
-
What are some slippery materials?
-
What makes a good sledding hill? What would it look like?
-
How will you make your sled move (up or down the hill)?
-
How many will fit on your sled?
Vocabulary:
-
sled, slope, hill, velocity, speed, angle, push, pull, motion
Reflection prompts:
-
What worked well? What part of your design do you like best or would you change? Why?
-

3: We worked together the whole time. We completed our plan.
2: We worked together most of the time and almost completed our plan.
1: We worked together a little bit. We needed some reminders or help from a teacher.
0: We did not work together. We did not complete our plan.
