In this activity, learners explore how the hull shape impacts a ship's performance and stability.

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.

In this activity, learners experiment with different variables in making hollandaise sauce to achieve the correct texture and consistency.

In this activity, learners explore sublimation by conducting experiments with dry ice.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

Learners observe working lava lamps to understand how they work (included in PDF link).

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

This fun and simple hands-on astronomy activity lets learners experiment with marbles and weights to discover some basics about gravity and black holes.

In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.

Using simple, inexpensive items, learners build and test submarine models.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

In this activity (page 23 of PDF), learners conduct an experiment to determine how the size and mass of a projectile affects the area and the volume of an impact crater.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

In this activity, learners explore the engineering behind life vests or personal flotation devices and the challenges met by these devices.

This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.
