Instilling Inquiry with Microscopes Betsy Sullivan Biology Teachers
Instilling Inquiry with Microscopes Betsy Sullivan Biology teachers know that the microscope is a basic piece of equipment. Students are thrilled to use the microscope, but few actually understand the science that developed the microscope. In the past, I have, as many other biology teachers do, introduce the microscope by sharing some of its history through a power point presentation or video. My students and I would discuss individuals that developed the microscope. However, we ignored the process of science in the history. Upon reflection I found that the microscope was actually a fantastic opportunity for my students to begin learning inquiry in science. I have used this activity in both high school and college level classes. Materials Required: Newsprint clear plastic (I use discarded lamination edging.) water Erlenmeyer flask, Florence flask, collection jar (any clear containers) pipette magnifying lenses construction paper tape binocular dissection microscope compound light microscope scissors lab notebook Engage: Students work in pairs to allow discussion of any phenomena noticed. Each pair is given a small sample of newsprint, a clear plastic square, container of water, and a pipette. Students lay the plastic on top of the newsprint and drop 1 drop of water on the plastic. In their lab notebooks students draw the water bubble that forms and describe any difference from the original. Students observe the print from different angles by moving around the water drop (and not moving the water drop itself). Students are allowed to add more drops of water and note any differences, through drawing and written notes. I ask the students if the print always appears the same at different angles.

Valence, the Combining Capacity of Elements and Molecules
Lab Session 12, Experiment 11: Valence, the Combining Capacity of Elements and Molecules One molar mass of an element or compound that produces or reacts with 1.008 grams of hydrogen has a valence of I. It follows that the same quantity producing or reacting with 2.016 grams of hydrogen is valence II, and producing or reacting with 3.024 grams of hydrogen is valence III, etc. In this experiment, the magnesium metal will be reacted with concentrated hydrochloric acid to produce hydrogen gas according to the following chemical equation: x Mg (sol) + x HCl (aq) → MgCl x (aq) + H2 (gas) 2 The hydrogen gas produced will be collected, its volume measured, and the mass in grams calculated using the ideal gas law: PV = nRT When using this equation, the units of the gas constant (R) must be consistent with the units used for the other quantities in the equation. The Handbook of Chemistry and Physics lists the value of R as R = 0.08206 L × atm × mol–1 × K–1 Thus, pressure (P) must be expressed in atmospheres, volume (V) in liters, and temperature (T) in Kelvin. 11A Experiment A sample of magnesium metal with an approximate mass of 0.24 grams will be reacted with excess hydrochloric acid. The hydrogen gas produced will be collected, its volume measured, and finally its mass in grams will be calculated. Chemicals Required: 6M hydrochloric acid Magnesium metal, Note: 12M HCl(aq) must be diluted. ribbon or granules Apparatus Required: 500 mL Florence flask 125 mL Erlenmeyer flask Glass tubing Metal or plastic trough Watch glass 100 mL graduated cylinder Rubber tubing Thermometer 58 The apparatus should be set up as shown in Figure 12.1.

Creating a Silver Mirrored Flask
WARNING NOTICE The experiments described in these materials are potentially hazardous. Among other things, the experiments should include the following safety measures: a high level of safety training, special facilities and equipment, the use of proper personal protective equipment, and supervision by appropriate individuals. You bear the sole responsibility, liability, and risk for the implementation of such safety procedures and measures. MIT and Dow shall have no responsibility, liability, or risk for the content or implementation of any of the material presented. Legal Notice Silver Water Creating a Silver Mirrored Flask Abstract Combine several solutions in a clean Florence flask. Stopper and swirl the flask. Within minutes, a beautiful silver reflective mirror coating forms on the inside of the flask, from the reduction of silver ions to silver metal. Materials 1.5 M Ammonium Nitrate solution 4-Graduated Cylinders 50 mL 2.5 M Sodium hydroxide solution 1000 mL Florence Flask 0.5 M Silver Nitrate solution 1-Beaker 100 mL Acetone Milli-Q Water Bottle 5% Dextrose Solution #8 Stopper to fit 1000 mL flask Disposable Gloves Safety Goggles Large 20-gallon bucket ¾ filled with H2O 2- 50 mL storage bottles Safety Silver nitrate is extremely toxic. It can cause severe burns along with discoloration of the skin and clothing. It could result in corneal damage, even blindness, if splashed into the eyes. Ammonium nitrate is also toxic. Care must be taken in avoiding contact with skin, eyes, and lungs. Contact with other chemicals or heat could result in fire or explosion. Sodium hydroxide is a corrosive material. Mixing the materials in this experiment has the potential to form an explosive compound.
