Connect the Dots: Isometric Drawing and Coded Plans
Individuals discover how to draw cubes on triangle-dot paper. They use cubes to build structures and draw corresponding isometric drawings on dot paper in the second lesson of the series of five. The activity also introduces the concept...
Teach Engineering
Let's Take a Spin: One-Axis Rotation
Investigate the effect of one-axis rotations on geometric figures. Scholars learn to use snap cubes and the right-hand rule to draw figures after rotations about the x-, y-, or z-axes. They try their hands at examples created by the...

Live Like an Animal
When your parents say that your room's a pig sty, tell them about biomimicry. The sixth installment of a nine-part Life Science unit has scholars research the shelters used by animals in the natural world, like turtle shells. Using the...
Teach Engineering
Design Inspired by Nature
Let nature guide your engineering designs. By taking apart a flower, pupils learn about reverse engineering. They use the results to brainstorm designs for new products or ideas. This is the seventh installment of a nine-part Life...
Teach Engineering
Extinction Prevention via Engineering
It's time to save endangered species through engineering. The third lesson in a nine-part Life Science unit has young environmentalists study species extinction. An engaging discussion leads to some ideas on how to use engineering design...

Exploring Energy: Kinetic and Potential
The potential of the energy in the class is moving. The third segment in a six-part unit on energy provides a deeper understanding of kinetic and potential energy. Learners understand the relationship between mass, speed, and energy and...
Teach Engineering
Maximum Mentos Fountain
A messy fountain is potentially an energy experiment in disguise. Groups investigate the variables in creating a fountain from soda and Mentos. The last activity in a six-part series on energy has the class observe the fountain in terms...
Teach Engineering
Exploring Energy: Energy Conversion
The energy is not really lost, it is just converted to a different form. Pupils learn about the conversion of energy in the fifth segment of an energy unit with six parts. Learners develop an understanding of the conservation of energy...
