Students make a wheel and axle out of cardboard and a wooden dowel. It is rooled along a ramp made of parallel meter sticks, and the acceleration can be made small enough to make accurate measurements and calculations.

In this lab exercise, students practice correctly using measurement tools, recording data, calculating density, using significant figures, and exploring the concepts of accuracy and precision.

This activity is acid-base titration lab where students determine the percent of calcium carbonate in an eggshell.

In this lab-based activity the students will use their knowledge about the law of conservation of energy to explain the loss of heat by warm water to cold water. Then, the students will use these concepts to design and carry an experiment to determine the unknown temperature of a hot water sample.

This activity is an indoor lab where students will make predictions of what a force vs time and acceleration vs time graph will look like for a ride in an elevator going down and up. Students will collect data remotely using a Force Plate and accelerometer and then download the data to the computer for further analysis.

In this inquiry activity, students generate investigable questions to explore the link between hygiene/cleanliness and bacteria growth/population. The students will present their conclusions, and video clips containing additional information will be discussed.

This activity is a lab investigation where students design a balloon car to collect data about speed and velocity.

This activity will allow students to see light bending. The students will be able to calculate the amount of bend or refraction that occurs with various mediums.

A 90 minute laboratory experiment utilizing observations and reasoning regarding the Law of Conservation of Matter and Energy.

Students investigate whether a bowling ball will float or sink in an aquarium of water after measuring the ball and determining the density. This is meant to be an investigative inquiry of the concepts of density and significant figures.

This classroom lab is a guided practice for inquiry using brine shrimp as the subject to be investigated.

This activity is a biology lab investigation where students create habitats to observe decomposers in a controlled setting.

In association with rock and mineral ID tables, this lab introduces students to basic rocks and minerals via grouping and comparison, rather than as individual samples. I use this lab in my environmental geology course, where we don't have enough lab time to examine each set of rocks and minerals separately, but students need a basic familiarity with these materials and a context in which to place them. I find these groupings teach them how to look at rocks and minerals and give them the cursory experience identifying geologic materials necessary to go on successfully in the course.

A lab where students determine the molarity of sugar and citric acid in samples of lemonade.

Students will discover the terminal velocity to mass relationship and use this information to calculate the air resistance constant. They will evaluate the accuracy of their lab using the Monte Carlo method.

This activity enables students to calculate the speed of sound in a laboratory setting.

This activity is a chance for students to apply the diffraction grating equation m*Λ/d = Θ to solve a real life problem: find the wavelength of given source of light. It is also useful for them to apply trigonometry to real life scenarios.

This activity is a indoor lab where student gather data about centripital acceleration and write up a lab based on their findings.
