This activity is a lab where students make qualitative and quantitative observation on a chemical change. They will see that gases have mass in accordance with the conservation of matter.

This lesson has students solving the mystery of a note by conducting chromatography. They will test different washable markers and see that different marker colors are made up of various pigments. They will compare and contrast the note chromatography with other chromatography results from a variety of markers.

This is a laboratory exercise designed to allow students to further investigate the light spectrum. This lab is used to have students view the light spectrum first hand as opposed to using lecture alone.

This lab activity is designed to allow students to experience what an increase in mechanical advantage means. Students determine the mechanical advantage of three pulley set-ups. Students also measure the work input and output, then calculate the efficiency. Finally, students determine the relationship between the mechanical advantage and the efficiency of the pulleys.

This activity is an entire-class lab experiment that refreshes the concepts of sinking and floating, while introducing the concepts of bouyancy and density using the fizz from sprite (carbon dioxide gas) and raisins.

In this lab activity, students determine density differences of water samples with varying temperature and salinity levels. Students synthesize information to predict the effects of oil in given water samples.

This activity is a lab where students design an experiment to test the rate of photosynthesis. Students will analyze data,write a report using the scientific method, and apply results to current environmental issues.

This is a lab activity where students observe the relationship between pressure and volume. They use their data to determine the formula for Boyle's Law.

In this activity, students will investigate how much chlorophyll is in olive oil using a Varnier Spectrometer. Students will measure and analyze the visible light absorbance spectra of three standard olive oils obtained from any supermarket: extra virgin, regular, and light.

This activity is an inquiry lab where students observe the effects of temperature change on nitrogen dioxide gas, a common component of polluted air, to determine its color.

In this short lab, students observe the movement of an air bubble in a small level, attached to a toy truck, as it is moved from a stop, to a steady speed and back to a stop. This gives a visual to the concepts positive acceleration, zero acceleration and negative acceleration.

This lab activity shows students the Law of Conservation of Matter and intermolecular forces by having them dissolve packing peanuts in acetone.

This activity is a bioassay lab where students tested the effect of an environmental toxin (fertilizer) on the growth rate of Duckweed.

This is a classroom activity in which students develop understanding of the rock cycle using wax crayons to model the processes that form the 3 types of rock; sedimentary, igneous & metamorphic.

Students will explore and create a healthy ecosystem, once established they will then introduce additional variables which may harm the ecosystem and determine which hazards should be avoided.

This activity is an in class lab where students will compare different acid solutions on seed germination and growth.

This activity is a lab investigation where students collect data concerning and endothermic and exothermic reaction.

This lab activity leads students to a better understanding of exo-endo- thermic processes. It also reinforces the necessity for proper lab safety equipment and disposal techniques.

This guided inquiry activity has students using models to create variations of alignment of the Earth, Moon, and Sun. By varying their arrangement, students will discover how the positions of the Earth, Moon and Sun interact, how shadows can be cast on the Moon and on the Earth, and how Earth's view of the lit portion of the Moon changes.
