INPUT ARTICLE: Article: Prepare to transplant gaura seedlings to an outdoor location after the threat of frost has passed in the spring. If you choose to purchase an established gaura seedling or plant from a garden nursery instead of growing one from seed, the same transplanting guidelines still apply. Note that many perennial varieties of gaura can be planted after the threat of frost passes in the spring or at the very beginning of autumn, before frost becomes an issue. Annual varieties must be planted in the spring, however. Gaura does best when planted in areas receiving full sun, but it can also tolerate spots that receive partial sun and light shade. You must choose a spot with well-draining soil. If your garden is filled with heavy soil, you must amend it before transplanting the gaura seedlings. Gaura shrubs develop a long taproot, so you will need to amend the soil to a depth between 1 and 2 feet (30.5 and 61 cm). Spread 6 inches (15.24 cm) of light organic matterpeat moss, compost, or sandover the top of the planting area. Use a shovel to dig the additive down into the soil to the appropriate depth. Make sure that the soil and organic material are evenly mixed. The soil should look notably looser when finished. Also note that the soil does not need to be especially nutrient-dense, but it should be fairly neutral with a pH between 5.5 and 7.2. Use a shovel or a trowel to dig a planting hole for the seedling. The planting hole for each seedling should be twice as wide as the seedling's current container. The depth of the planting hole should only be about as deep as the current container, though. Avoid planting seedlings too deep. The top of the root mass should be just beneath the surface of the soil. Before you remove the seedling from its current container, give the soil a thorough watering. Watering the soil makes it more compact and easier to move. Carefully remove the seedling from its container and center it in the planting hole. Hold the plant securely at the base of the main stem, just above the surface of the soil and the root mass. Slowly invert the container until it is tipped diagonally downward. Squeeze the sides of the container with your other hand or tap on the container with the handle of your trowel or shovel. This should loosen the plant and free it from its container. Grab the bottom or side of the removed mass. Carefully place the plant right-side-up in the planting hole. Continue to hold it steady above the root mass with one hand. Use your free hand to fill the rest of the planting hole with soil. Once the plant is stable, let go of it and use both hands to gently pat the soil down. The soil around the plant should be fairly loose but still packed well enough to hold the plant in place. Give the entire planting site a thorough watering to help settle the soil. Gaura does well when planted in nearby clusters or planted around other perennial shrubs. Small varieties should be spaced 8 to 12 inches (20 to 30 cm) apart. Large varieties should be spaced 20 to 36 inches (50 to 90 cm) apart. Planting the gaura close together can prevent the roots and stems from becoming too leggy.

SUMMARY: Transplant in the spring. Choose a sunny spot. Provide plenty of drainage. Dig a hole twice as wide as the container. Water the seedling well. Transfer the seedling from the container to the planting hole. Pack the soil around it. Plant separate gaura seedlings close together.

In one sentence, describe what the following article is about: For optimal viewing of Mars, track its orbit with a sky map or chart to keep track of its distance from Earth. A sky map is a map of the night sky that indicates the location of planets, stars, constellations, and other celestial bodies. Interactive versions are available online (for example, visit http://www.sky-map.org/), or you can download an app for your smartphone. Make sure to get the right map for your current location, and for the current date. Mars' closest approach to Earth occurs every 26 months, but it appears the brightest eight days earlier, on the date of opposition. This date marks the point in the planet's orbit when it rises in the east as the sun sets, which makes it visible in our sky overnight. While there are many other opportunities to view Mars in the night sky, this biennial event should not be missed if you are truly interested in observing the planet. Ensure that the weather will be favorable and the skies will be clear for the night and time when you intend to observe Mars. Cloudy skies, and certainly precipitation, will impede your viewing. Consult a local weather report, or a clear sky chart online to predict weather conditions for the near future.
Summary: Track Mars' orbit. View Mars on the date of opposition. Aim for ideal weather conditions.

Before you can do an around the world, you need to be confident juggling the ball. Practice bouncing a soccer ball up and down on your foot as many times as you can. Pretend you have a ball bouncing on your foot. Practice making a circular motion with your foot moving around "the ball" in the air. You want to do one smooth motion in which you juggle the ball up and then rotate your foot around it. Start with the ball cradled on top of your dominant foot. Toss it up into the air with your foot and practice getting your foot all the way up and around the ball, then catching it. Once you've gotten this down, you can move on to doing an around the world while juggling the ball. Don't feel bad if you don't get the trick down right away. It may take you days or weeks to get it down. Stay calm and focused, and keep practicing until you succeed.

One-sentence summary -- Practice juggling a soccer ball. Try the movement without a ball. Attempt an around the world without juggling the ball. Keep practicing.

INPUT ARTICLE: Article: Look for Styrofoam balls that are around 1 inch (2.5cm) in diameter. Make sure you get white balls since you'll need to paint them different colors for your project. You can find Styrofoam balls at your local craft store or online. Use red, blue, yellow, and orange to paint the balls in the piles. These balls will make up the inner strands of your DNA model, which represent guanine, cytosine, thymine, and adenine. When you're finished painting each ball, set it aside to dry on a sheet of newspaper or a paper towel. You should have 6 red balls, 6 blue balls, 6 yellow balls, and 6 orange balls.

SUMMARY:
Purchase 48 white Styrofoam balls for your project. Split the other 24 balls into piles of 6 and paint each pile a different color.
