In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!

In this math-based activity, learners will experiment to find how height and angle affect spatter and then use this knowledge to solve a crime.

In this math activity, learners use a "function machine" to collect and organize simple data. The function machine in this case is a cardboard box and the input/output data are paper fish.

This is an activity about reaction times. Just how quickly must an NHL goalie respond to save a shot, and how does your reaction time compare?

This activity was designed for blind learners, but all types of learners can utilize it to investigate volume, mass, and density.

In this activity, learners investigate the properties of different types of balls.

From the Weather Watchers featured theme on the CYBERCHASE website. Learners will conduct experiments to discover how air temperature and humidity work together to make condensation, dew, and fog.

In this math activity related to light, learners explore why a light, such as a candle or a streetlight, looks dimmer the farther away from it we get.

In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.

In this math lesson, learners analyze the density of liquids in order to explore linear functions.

In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.

In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.

In this math lesson, learners explore polynomial and rational function patterns.

In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

In this math lesson, learners explore and investigate measurement using standard and non-standard units.

In this activity (page 10 of PDF), learners approximate the area of the uppermost cross section of an impact crater using a variety of square grids.

In this math lesson, learners learn how to construct stem and leaf plots. Learners first estimate the number of drops of water that will fit on the head of a penny.

In this activity (page 23 of PDF), learners conduct an experiment to determine how the size and mass of a projectile affects the area and the volume of an impact crater.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

In this space science activity, learners explore transits and the conditions when a transit may be seen.
