article: All-mountain boards are equally at home heading down the mountain and hitting jumps at the terrain park. They blend speed and maneuverability well, and are thus the perfect board for beginner riders or someone who wants to board downhill, half-pipes, or backcountry in the same day. Size: If you stand the board up on it's end, the top should reach between your nose and chin. Directional Twin-Tip This hybrid shape can comfortably ride with either direction facing forward, but the front end is often tapered up slightly to make it faster downhill. Camber Type: All-mountain boards usually come in camber shapes which curve upward. However, beginner riders should try a rocker-style because of the added maneuverability and turning forgiveness. Freestyle board are usually smaller so they don't get in the way during tricks. They are highly maneuverable and light, but they have less speed and stability when going downhill. That said, they can still be used to to bomb down a mountain in a pinch. Size: Since freestyle boards are usually smaller, choose one that feels comfortable to you. Stand the board up and look for something that reaches between your shoulder and chin. Twin-tip: Freestyle riders will almost always want a twin-tip design, as this allows them to comfortably board in either direction after jumps or tricks. Camber Type: Most freestyle riders prefer a "camber" shape, where the board curves slightly upward between the tips. This spring-loads the board to give you maximum pop on jumps. These boards are made to be quick and stable at high speeds. They are generally stiffer and have the bindings slightly set towards the back of the board. Size: Usually the longest board type, a freestyle board will often reach near your forehead when stood on end. Directional: All freeride boards are directional, meaning there is a designated front end to increase speed. Camber Type: Freeride boards come in a variety of shapes, but one of the most common is a rocker/camber/rocker hybrid that curves down near the tips and up in the center. Powder boards are usually made for downhill riders who encounter a lot of fresh, soft snow. They have longer or tapered noses and raised ends to help stay on top of powder. The bindings are generally set towards the back of the board to keep the front end up. Size: Generally longer to increase surface area and speed, since powder boards are not often used for tricks. Directional: Most powder riders prefer directional boards, since the design allows them to sail smoothly over fresh snow. Camber Type: Powder boards usually have a rocker-shape, which is when the entire board curves slightly upward. This keeps the tip and tail elevated so it doesn't get caught in the deep powder.

article: This type of protractor is shaped like half a circle, with angles marked all around the rim. You can buy them anywhere that sells school supplies. Ideally, choose a protractor with a small hole near the center of the protractor, along its straight base. If you don't want to buy one, you can search online for a printable protractor. Print it out, cut it very carefully along its outline, and glue the paper protractor to something a little sturdier, such as construction paper or an index card. Tape a straight, plastic drinking straw on or near the straight edge of the protractor. Make sure the straw passes through the two 0 or zero marks on opposite ends of the straight edge. If you don't have a straw, roll a piece of paper into a tight cylinder and use that instead. Many protractors come with a small hole directly between the 0 marks on the protractor, across from the 90 mark on the curved edge of the protractor. If your protractor does not have a small hole here, or if the hole is not situated correctly, tape or glue the string to the protractor where the hole should be. Make sure the string dangles a few inches (several centimeters) below the protractor. If you are using a paper protractor, you can punch the hole yourself with a sharp pen or hole punch. Do not try to punch a hole in a plastic protractor, as it is probably made from weak plastic and could shatter. Tie a paper clip, metal washer, or other small weight to the end of the string. When you hold the clinometer so the string falls past the circular rim of the protractor, the weight will pull the string straight down past an angle mark on the protractor, such as 60. This tells you what angle the clinometer is being held at, which can be used to find the heights of distant objects as described in the section below.

article:
Outside, create an enclosure or fenced in area for them to play in. You can use a wire fence or cage, as long as it doesn't leave gaps that your guinea pigs can escape through. Guinea pigs can't stand too much heat, so make sure you keep them cool when they go outside. For one, you should always provide them with shade, so they can cool down. In addition, only let them out during cooler times of the day in the summer. Guinea pigs prefer temperatures between 65 and 75 degrees Fahrenheit. While they can stand a bit more variation, you don't want to go too much colder or warmer. Damp grass can give your pig a chill, and that's not good for them. Also, make sure you aren't setting them down on grass that has been sprayed with insecticides or other chemicals, as that can be damaging for your guinea pig. Once again, you want to be sure to always provide your guinea pig with food and water. Water is especially important when your guinea pig is outside because it can easily get dehydrated when it is warm out. Guinea pigs love to chew on any plant in their vicinity, which is fine when they're munching on grass. However, some plants are poisonous to guinea pigs, so you want to make sure they don't have access to those. Use a database like Cornell's http://poisonousplants.ansci.cornell.edu/index.html to look up poisonous plants in your area. Many common plants like daisies and buttercups are poisonous to guinea pigs. If you keep your guinea pigs just on grass without weeds, you should be fine. You do not want to leave your guinea pig unattended outside. For one, if your enclosure doesn't have a roof, your guinea pig could easily be carried off by a predator. It could even happen if your enclosure does have a roof. In addition, you want to make sure your guinea pigs don't wriggle out and escape. Also, because guinea pigs are susceptible to heat stroke, you want to keep an eye on them while outside. Signs of heatstroke include lethargy, a limp body, trouble breathing, a rapid pulse, and a wet chin. Your guinea pig may also feel hot to the touch. Check the ears to see if they feel extra warm. If you notice signs of heatstroke, bring the guinea pig indoors. Use tepid water (not cold because it can cause shock) to dab around the ears and feet. You can even dip its feet in water. Once the guinea pig seems cooler, take it to the vet.
