Measuring spoon

To measure a dose, scoop out a tiny piece with a small measuring spoon e.g. 1./4 tsp size. Fill the measuring spoon with the extract. Since this is strong stuff and 1/4 tsp. is a large dose so you may want to use an 1/8 tsp. measure, or alternatively measure 1/4 tsp. and then cut than in half to get approximately 1/8 tsp. 

Liquid soap or detergent, measuring spoons, pump-spray bottles, plants infested with household or garden insect pests such as houseflies or aphids... 

Use the measuring spoons to create various concentrations of soap solution. Stir your solutions gently to avoid excessive foaming. Pour each solution into a pump-spray bottle,... 

In a large plastic measuring spoon, dissolve 1/4 teaspoon of lye flakes in an equal amount of water. If lye powder is used, halve these amounts. 

A set of plastic or stainless steel measuring spoons will facilitate transferring chemicals from the bottle to the scales. They will help to prevent wasteful spills, which can cause contamination. Do not overfill the spoon transfer a little at a time to prevent spilling. 

This part includes information on providing a suitable container for items supplied via an NHS prescription form. To cover the cost of containers and other items which may need to be supplied to patients (for example, a 5-mL plastic measuring spoon) every prescription (except an oxygen prescription) will attract a flat fee for supplying a container, whether or not one was supplied. 

In order to measure an accurate dose a standard measuring spoon is provided with any liquid medication. The standard spoon size is 5 mL (see Figure 9.9). 

For approximating, a liter and a quart are similar volumes. Kitchen measuring spoons are used in estimating small volumes. 

Assemble and hang the Check Your Science Pall poster (see Appendix C for instructions). This will help students keep their pails complete and speed along cleanups. Attach the goggles strip, unknowns strip, and measuring spoons strip to the poster. 

Then explain that five teams will be at the station at a time, one team at each unknown. Also tell students that while they wait for their turn at the station, they will color-code their measuring spoons by placing a small dot of a different color on the handle of each spoon. Review the following Instructions (on pg. 8 of the Student Activity Book) ... 

Now finish color-coding your measuring spoons. 

Alter you ve filled your jars and color-coded your measuring spoons, look at Figure 2-6. That s what you should have at the end of this activity. 

Take out the red unknown sample jar and red measuring spoon. Open the jar. 

Set up your tray, test mat, and wax paper. With the red measuring spoon, take one sample of the red unknown. 

Wipe off the measuring spoon with a paper towel before you put it back in the spoon bag. Put the unknown jar back in your science pail. 

Using your red measuring spoon, add one measure of the red unknown to the cup. Stir the mixture with a toothpick for 30 seconds. 

Place one science pail of unknown samples and measuring spoons at the station. Also put the foil-lined trays, bake cups, clothespins, and toothpicks at the station. They will be distributed to each group of five students. 

Using one of your measuring spoons, put a sample of the goo inside the compare circle. 

Use the measuring spoons to combine two or three measures of up to three of the chemicals.
