In this optics activity, learners make a simple telescope using two lenses and a cardboard tube. Learners construct the telescope and then calculate its magnification.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this activity, learners use a straight line to learn about circles. Learners measure and record the diameter and circumference of different sized cylindrical objects on a chart.

Create beautiful spirals by drawing a straight line. This sounds crazy, but you can with a turntable (a record player or lazy susan), paper, and pen.

In this activity, learners will train to increase bone strength and to improve heart and other muscle endurance by performing jump training with a rope, both while stationary and moving.

In this activity (on page 2 of the PDF under GPS: Luge Activity), learners will construct a model hovercraft out of an empty spool and a piece of cardboard.

In this activity, learners investigate just how small a billionth of a meter is by attempting to cut a paper ruler down to a nanometer-sized sliver.

Learners place an M&M candy in water and observe what happens. The sugar-and-color coating dissolves and spreads out in a circular pattern around the M&M.

In this on site "field trip" activity (located on pages 6-9 of PDF), learners get hands-on experience identifying building materials by playing "Building Bingo".

In this activity about light and reflection, learners use a special device called a Mirage Maker™ to create an illusion.

In this activity, learners explore a surprising method for calculating the mathematical constant pi, known as Buffon's Needle.

In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp

In this activity, learners will build the highest tower they can out of recycled materials.

As learners play this game, they build skills in area, perimeter, multiples and factors. They take turns making rectangles with 12 squares on the grid.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

¡Este juego de estrategia tiene reglas sencillas pero puede ser un reto! Los jugadores empiezan con una red de hexágonos vacía. En su turno cada jugador pone su inicial en un hexágono vacío.

In this activity, learners interpret three trackways and use measurements and a formula to infer the relative speed of dinosaurs.

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

This lesson plan enables learners to explore the differences between weather and climate.

In this math game (Page 14 of the Are You Game? PDF), learners determine the probability of getting an even versus an odd product using the numbers on a regular deck of cards.
