A former NASA engineer builds absurdly ambitious things and shows the reasoning underneath them. This collection spans the squirrel obstacle courses (three of them, each a bigger engineering build and an accidental animal-behavior study) alongside a dartboard that moves itself to catch the dart, 25 million water beads dumped in a pool to test buoyancy, and 200 wallets dropped across cities to turn honesty into data. Several aim squarely at classroom projects: egg drops, mousetrap cars, ten science-fair ideas done properly. Most run ten to twenty-plus minutes, so plan on one as the anchor of a period rather than a filler.

NGSS (Science) 20
- 3-5-ETS1-1Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
- 3-PS2-1Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.
- 4-LS1-2Use a model to describe that animals receive different types of information through their senses, process the information in their brain, and respond to the information in different ways.
- 3-PS2-2Make observations and/or measurements of an object's motion to provide evidence that a pattern can be used to predict future motion.
- 4-PS3-1Use evidence to construct an explanation relating the speed of an object to the energy of that object.
- 3-5-ETS1-3Plan 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.

- 4-LS1-1Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.
- 4-PS3-3Ask questions and predict outcomes about the changes in energy that occur when objects collide.
- 5-PS1-4Conduct an investigation to determine whether the mixing of two or more substances results in new substances.
- 1-PS4-1Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate.
- 4-PS3-4Apply scientific ideas to design, test, and refine a device that converts energy from one form to another.
- 5-ESS3-1Obtain and combine information about ways individual communities use science ideas to protect the Earth's resources and environment.
- 4-PS3-2Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.
- 4-PS4-1Develop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can cause objects to move.
- 4-PS4-2Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen.
- 5-PS1-3Make observations and measurements to identify materials based on their properties.
- 5-PS2-1Support an argument that the gravitational force exerted by Earth on objects is directed down.
- 3-5-ETS1-2Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
- 4-ESS3-2Generate and compare multiple solutions to reduce the impacts of natural Earth processes on humans.
- 5-PS1-1Develop a model to describe that matter is made of particles too small to be seen.
