Three-Dimensional Space
How do 2-D properties relate in 3-D? Lead the class in a discussion on how to draw and see relationships of lines and planes in three dimensions. The ability to see these relationships is critical to the further study of volume and other...

Pop! Rockets
Off they go — launching rockets is fun. The lesson plan contains templates to build paper rockets that can be launched from a PVC pipe launcher. Individuals or groups build the rockets and determine the shapes for their fins. Included...

Foam Rocket
When going for distance, does it make a difference at what angle you launch the rocket? Teams of three launch foam rockets, varying the launch angle and determining how far they flew. After conducting the series of flights three times,...

Launch Altitude Tracker
Using PVC pipe and aquarium tubing, build an altitude tracker. Pupils then use the altitude tracker, along with a tangent table, to calculate the altitude of a launched rocket using the included data collection sheet.
NASA
Rocket Wind Tunnel
Using a teacher-built wind tunnel constructed from a paper concrete tube form, a fan, and a balance, individuals determine the amount of drag their rocket design will experience in flight. Pupils make modifications to increase the...

Lights on the International Space Station
Groups explore illumination with NASA's Lighting Environment Test Facility (LETF) as a context. Using the TI-Nspire app, groups determine the lux equation that models their simulation. They then use the lux equation to solve problems...

Observations and Inference
What's the difference between qualitative and quantitative observations? Learners make observations, inferences, and predictions about their environment with a set of questions and activities that are applicable to either language arts...

Review Unit 8: Geometry Applicaitons
Pupils complete a review worksheet that highlights the key problems from the first eight lessons in the series. Topics include the Pythagorean Theorem and its converse, as well as finding volume of three-dimensional figures.

Unknown Angle Problems with Inscribed Angles in Circles
We know theorems about circles—now what? Class members prove a theorem, with half the class taking the case where a point is inside the circle and half the class taking the case where a point is outside the circle. The lesson then...

The Multiplication of Polynomials
If you can multiply multi-digit integers, you can multiply polynomials. Learners use an area model to compare multiplying numbers to multiplying polynomials. They progress to using the distributive property.

Genome: The Secret of How Life Works
What do you have in common with a fruit fly? About 60 percent of your DNA. The resource, divided into two units, is intended for grades four to eight and another for high schoolers. Both units include eight lessons covering the genome as...

Generalizing Patterns: The Difference of Two Squares
After completing an assessment task where they express numbers as the difference of squares (i.e., 9 = 5^2 – 4^2), class members note any patterns that they see in the problems.

Are All Parabolas Congruent?
Augment a unit on parabolas with an instructive math activity. Pupils graph parabolas by examining the relationship between the focus and directrix.

Protecting Our City with Levees
Teams use the design process to design, build, and test a model levee to protect the town from a wall of water. A handout provides a price list for the materials learners can use to build their levee within a budget.

Cartesian Diver
Amaze your scholars with an activity that uses a Cartesian diver to demonstrate Pascal's Law, Archimedes' Principle, and the Ideal Gas Law. Groups then repeat the process and make their own diver move up and down in a bottle.

Creepy Silly Putty
It might be silly to determine the creep rate of putty but groups will enjoy making different formulations of silly putty and playing with them to understand how the different mixtures behave. The second part of the activity has groups...

Chromatography Lab
Groups use alcohol and chromatography paper to separate the color components of black ink. The purpose of the activity is to allow the class to become aware that mixtures exist in hidden places.
Inside Mathematics
Magic Squares
Prompt scholars to complete a magic square using only variables. Then they can attempt to solve a numerical magic square using algebra.

Number Towers
Number towers use addition or multiplication to ensure each level is equal. While this is common in factoring, it is often not used with algebraic equations. Solving these six questions relies on problem solving skills and being able to...

Mapping the Field of a Dipole Magnet
High school scientists build their own magnetometer and use it to map the field surrounding a bar magnet. Excellent background resources is included, as well as a diagram of how to build the magnetometer.

Earth’s Magnetic Field from Space
Feel the pull of science! The final installment of this 18-part series is an application of everything learned in the previous high school lessons. Scholars are given a magnetic field map and must propose an arrangement of magnets that...
PHET
Mapping the Field of Multiple Dipole Magnets
So you built a magnetometer, now what? High school scientists use their magnetometer made in a previous lesson to map the union of magnetic fields of dipole magnets. They experiment with different alignments and draw conclusions about...
