In this three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.

In this math lesson, learners practice estimation and measurement skills as they move from station to station calculating length, volume, weight, and area.

In this activity (on page 2 of the PDF under GPS: Biodiversity Activity), learners will pair up and take a notebook outdoors to a selected location to observe and record a list of living things that t

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this math activity, learners play a game and try to be the first player to identify their partner's rule. Learners identify the rule by finding commonalities between three familiar objects.

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

In this activity, learners discover how their heart rate changes in different situations.

This simple but open-ended math game introduces basic probability concepts using coins and dice. Players roll the dice and collect coins to match the number rolled.

Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.

In this activity, learners track their movements with jumping and leaping graphs.

In this math activity, learners guess a secret number between 1 and 100 in a three-player game.

In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.

In this math lesson, learners use fruit to learn about proportions and percentages. Learners compare the weights of the edible and non-edible portions of fruit.

In this activity (11th activity on the page), learners use pennies to test their hearing acuity.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi

In this weather activity (page 10 of the PDF), learners will demonstrate the changes in atmospheric pressure by constructing their own barometer.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.

In this health activity, learners create a device so that they not only feel their heartbeat, but also see it, using a straw and some clay.

In this activity, learners "go fishing," then practice ruler use and size/pattern comparison with the animals they catch.
