Article: When your timer is done, tell all of the players to stop. Have the players meet you back at the starting place, and count each team's findings individually. If you are playing in a large space, you can blow a whistle to designate the end of the game. Tell the players to listen for the whistle before you start. Whichever team has the most objects found at the end of the game is the winner. Congratulate the winning team, and say something like "Great job!" or "Nice effort!" to the other team. If there is a tie, offer 1 final clue as a tiebreaker. The first team to find the final object breaks the tie and wins the game. Once 1 team is dubbed the winner, it's time to celebrate! Give the team their prize to congratulate them on a job well done. You should have the prize ready to present when the game is over. For example, give 1 candy bar to each player on the winning team. Purchase the candy bars in advance so they are ready to give out when the game ends.

Count up the total objects found on each team when time runs out. Designate the team with the most clues found as the winner. Award the winning team their prize after the game is over.
Article: (FW) of the compound you are using. The formula weight (often used interchangeably with molecular weight) of a compound will be listed in grams/mole (g/mol) on the side of the chemical bottle. If you cannot find the formula weight on the bottle, you can search for the compound online to find it. For example: The formula weight of sodium chloride (NaCl) 58.44 g/mol. The formula weight of a compound is the mass in grams of one mole of the compound. It is very simple to make a 1-liter solution since molarity is measured in moles/liter; however, you may need to make more or less than a liter depending on what you're using the solution for. You will use the final volume of the solution to calculate the number of grams needed to make your molar solution. For example: Make a 50 mL solution of 0.75 molar NaCl. To convert mL to L, divide by 1000: 0.05 L. To calculate the number of grams needed you will use the equation # grams = (desired volume)(desired molarity)(formula weight). Remember, the desired volume needs to be in liters, molarity is in moles per liter, and formula weight is in grams per mole. For example: If you want to make 50 mL of a 0.75 molar solution of NaCl (FW: 58.44 g/mol), you can calculate the number of grams of NaCl needed. # grams = 0.05 L * 0.75 mol/L * 58.44 g/mol = 2.19 grams NaCl. When you cancel all units, you should be left with grams of the compound. Using a properly calibrated balance, weigh out the necessary mass of the compound. Place a weighing dish on the balance and zero it out before weighing. Add the compound to the dish until you have the correct amount. For example: Weigh out 2.19 grams of NaCl. Clean the balance when you are finished using it. Most solutions will be diluted using water unless otherwise specified. The volume of the liquid to be used is the same that you used to calculate the mass of the compound. Mix the compound and the water together until the powder is fully dissolved. For example: Using a graduated cylinder (measuring equipment for volume), measure 50 mL of water and mix it with the 2.19 g of NaCl. Mix until the powder is fully dissolved. Clearly label the solution with the molarity and the compound so it can be easily identified in the future.

Article: If you are using a stem cutting, remove the lowest cluster of leaves. Strip them with the same, sterilized knife, leaving the lowest 24 inches (510 cm) of the stem bare. Don't remove remaining leaves higher up on the stem cutting. If buds are on your cutting, leave them on. Commercial rooting hormone powder may hasten the development of the cutting, and often includes an antifungal agent as well to prevent rot. This treatment is recommended for rotting cuttings and for older, "woody" stem cuttings, but is typically not necessary otherwise. Some gardeners report success using ground cinnamon as a cheaper alternative to antifungal treatment, sprinkling it onto the cut end. Keep the cutting on a paper towel away from direct sunlight, and check on the cut end regularly. The cut should dry out, making the new plant less susceptible to rot. Stem cuttings can be planted after one or two days of drying. Leaf cuttings undergo a more visible change, growing a "callous" over the cut surface. This can take anywhere from two to seven days. If a leaf shrivels significantly during this time, you may need to plant it early. This has a lower success rate, but the leaf may die if it dries out completely. While waiting for the cuttings to dry, fill a small pot with a fast-draining succulent or cactus potting mix. If you wish to make your own, mix together three parts potting soil, two parts sand, and one part perlite. Use coarse, salt-free, store-bought sand if possible, since hand-gathered sand may contain microorganisms or salts that could harm plants. Succulent plants thrive in pots that aren't too much bigger than the plant itself. Pots that allow for about an inch or two of growing room should be fine while the cutting is getting started. The pot must have a drainage hole. Stems cuttings can be planted as usual, burying the stem until the lowest leaves are just above the soil, but not touching it. Buried leaves are more likely to rot, so if you have a leaf cutting, try just touching the cut end to the soil surface, propping the leaf up with pebbles. Succulents don't need a lot of water, in general. Still, you'll need to water cuttings every 2 to 3 days or so while they establish roots. Once the plants have started to build a root system, you can cut down to weekly watering or whenever the soil is dry. Don't be worried if the cuttings look like they're drying out, at first. This means the plant is using its stored energy while it puts down new roots. If things work, you should start to see new growth in about 4 weeks.

Strip leaves from the lower part of the stem. Dip the cut end in a rooting hormone (optional). Let the cutting dry out in a lightly shaded location. Prepare a succulent potting mix. Select an appropriately sized pot to plant your cutting. Plant the cutting. Water occasionally.
