# Perimeter Inspirations: Figuring Outer Space

September 01, 2018

*Figuring Outer Space**is an inquiry-based educational resource. Hands-on activities focused on stars, exoplanets, the Milky Way, and Crab Nebula stimulate learning for students using this resource. Students explore the life cycle of stars, sequence images, model a method for detecting exoplanets, learn about key features of our home galaxy—and more. Math topics include using ratio and proportion, exponents, percent and proportion, and mathematical modelling—as well as graphing data and evaluating algebraic expressions. This digital resource is designed to excite learning in Science, Technology, Engineering, and Math (STEM) with an emphasis on 21*

*century skills—including collaboration, problem solving, and critical thinking.*

As usual with Perimeter Institute products, this downloadable resource comes in both PDF and Microsoft Word versions, so you can customize it if you want to.

# Perimeter Inspirations: A Deeper Understanding of Energy

September 01, 2018

*A Deeper Understanding of Energy**is an inquiry-based educational resource. Hands-on activities focused on energy explore energy transformations in everything from everyday technology to stellar dynamics and the expanding universe. Students model energy transformations using energy flow diagrams and work-energy bar charts, as well as algebraic methods.*

Opportunities are provided throughout the resource for students to explore the role of energy in the nucleus as they consider nuclear transformations, ionizing radiation, and mass-energy equivalence. The power of conservation laws is illustrated as students work through a series of experiments that expands their understanding of how scientific models evolve.

This digital resource is designed to excite learning in Science, Technology, Engineering, and Math (STEM), with an emphasis on global competencies—including critical thinking and problem solving, collaboration, and communication.

I used the draft version of this last year, trying most of the activities. I think they are worthwhile. I did find the time estimates a bit optimistic — allow for up to 50% more time to complete an activity than the lesson plan suggests.

# Perimeter Inspirations: Wave Model Applications

September 01, 2018

*Wave Model Applications**is an inquiry-based educational resource. Hands-on activities focused on waves explore the far-reaching extent of the wave model for understanding and manipulating natural phenomena. Students are introduced to the basic properties of waves and how they are used to solve problems.*

Opportunities are provided throughout the resource for students to explore the breadth of technologies that use wave phenomena to reduce noise, image ship wrecks, study earthquakes, and detect gravitational waves. The fundamental properties of sound are also explored to build a deeper understanding of how the human ear functions.

# Perimeter Inspirations: Evidence of Change

September 01, 2018

*Evidence for Climate Change**is an inquiry-based educational resource. Hands-on activities focused on heat, carbon dioxide, and thermal expansion explore the essential science behind climate change. Students are introduced to the observational data for climate change and the climate models that describe the principal factors involved. Opportunities are provided throughout the resource for students to consider how they contribute to both the problem and the solution.*

Math topics include using trigonometry and geometry to calculate the carbon stored in trees, using algebraic equations to calculate carbon footprints, and solving linear relations to make better decisions.

As usual with Perimeter Institute products, this free downloadable resource comes in both PDF and Microsoft Word versions, so you can customize it if you want to.

I used the draft version of this last year, trying almost all the activities. I think they are worthwhile, especially if your math department will cooperate by doing the math connections in math class. I did find the time estimates a bit optimistic — allow for up to 50% more time to complete an activity than the lesson plan suggests.

# In Our Time: Echolocation

July 04, 2018

**In Our Time**is a wonderful series on BBC Radio 4.

*Melvyn Bragg and guests discuss how some bats, dolphins and other animals emit sounds at high frequencies to explore their environments, rather than sight. This was such an unlikely possibility, to natural historians from C18th onwards, that discoveries were met with disbelief even into the C20th; it was assumed that bats found their way in the dark by touch. Not all bats use echolocation, but those that do have a range of frequencies for different purposes and techniques for preventing themselves becoming deafened by their own sounds. Some prey have evolved ways of detecting when bats are emitting high frequencies in their direction, and some fish have adapted to detect the sounds dolphins use to find them.*
