Here’s a way to clean those hard-to-reach spots in glassware. Add a little dry rice to some soapy water and pour it into the glassware. Agitate the glassware by hand, and the rice and soapy water will scour the inside clean. This works well for volumetric flasks, aquarium filters, narrow-necked bottles, and other glassware.

Here’s a way to make your classroom a bit greener and show students that waste can be useful. Do you enjoy having guinea pigs or rabbits in the classroom, but feel guilty throwing out bags and bags of sawdust each week? Go green and start your own compost pile. The nutrients in the animal feces and carbon in the sawdust make great activators for a slow-going compost pile. Just remember to add some fresh greens, too.

Forensics teachers take note. Here’s how to make realistic artificial blood for blood spatter labs:
Pour one liter of water into a suitable container.
Add 8 oz red food coloring and one 16-oz bottle of Karo® Light Corn Syrup.
Mix thoroughly.
You must use Karo® Light Corn Syrup; imitations don’t work. For more realistic color, add a pinch of Congo red indicator powder. If you want to examine the artificial blood under a microscope, add a tablespoon of dry yeast. The spheres that form around the yeast granules look just like erythrocytes.

Here’s a way to help your students improve their literacy and learn about current events in science. Every week I have my students select a science-related article from a newspaper, magazine, or online source. Each student attaches a hard copy of the article to a piece of construction paper and does the following:
To make sure my students understand the assignment, I walk them through it the first time. I select an article, print it on a transparency, and read it aloud. Then I demonstrate each of the steps above, so that students know exactly what to do. Finally, I give them a set of printed instructions along with an example of a completed article.

To make sure that all equipment is returned at the end of a lab period, hand each lab group its equipment in a plastic plant tray. At the end of the lab all reagents and glassware initially handed out are placed back in the tray, allowing you to inventory the equipment and quickly clean, replace, and restock it for the next lab. Green plastic plant trays are inexpensive, durable, easy to wash and available in a variety of sizes from Carolina. I couldn’t keep equipment organized and my lab running efficiently without them.

Don’t let your students throw fruit and vegetable leftovers in the trash. Instead, have them deposit their leftovers in the school compost bin. Then use the resulting compost in your class or school garden.

My students were having trouble telling the difference between a 20 x 150-mm test tube and an 18 x 150-mm test tube. Using permanent markers, I put a blue dot on the 20s and a red dot on the 18s. Now we can identify them at a glance using the dots. Some dots do wash off after a while and need to be redone, but it’s worth it.

Keep a set of clean, empty reagent bottles on hand to inventory your chemicals. Here’s how you use them. Take your electronic balance with one of them and then weigh all bottles of the same size that contain chemicals, thus yielding the grams of chemical in each bottle. Repeat the process for each bottle size in your inventory.

Here’s a quick, hands-on project for your next Earth Day Celebration or Sustainability Fair. Have your students make compost tea, a nontoxic alternative to chemical-based plant food and insecticide, by doing the following:
During your Earth Day Celebration, allow students to spray the tea directly on plant leaves or to apply it to the soil in the school garden. At your Sustainability Fair, students can give sample bottles of the tea to attendees.

Here’s a fun way to prepare your class for Earth Day celebrations. Have
your students plant some seeds in pots, place the pots on a windowsill, tend
the seeds, and watch them grow. When the seedlings are ready to transplant
(on Earth Day, weather permitting), plant them in the school garden for all
to enjoy.

When we are studying forensics, I have each student make a “case file.” In the file, the student places his or her hair sample (mounted on a slide), footprint (made on black paper with baby powder), fingerprint, writing sample, and “DNA analysis.” (For the DNA analysis, I read from a list of characteristics and each student answers on notebook paper with a black line for every characteristic that matches him or her. In the end it looks like a print from a DNA electrophoresis gel.) I then give each student another student’s case file. Students have to figure out who has who by only looking at the evidence given to them in the files. Some of the evidence is missing—as it would be in a real crime case.
