While valerian root is a fairly safe herbal supplement, there are some side effects that you may experience while taking it. These include dizziness, headaches, and stomach problems. In addition, you may feel very drowsy, even after a full night’s sleep, so it is important to use extreme caution when driving or operating machinery. Valerian root is not right for everyone. Before you take it, talk to your doctor to ensure that it is safe for you.  Women who are pregnant or nursing should not take valerian root. Children under 3 years old should not take valerian root. People with liver disease should not take valerian root. Valerian root may interact with prescription medications and other herbal supplements you are taking. Always talk to your doctor about all of the medications and supplements you take.  Valerian root is known to interact with alcohol and sedatives. Valerian root may also affect your liver function, so be cautious if you are taking medications that are broken down by the liver. If you suffer from insomnia, taking valerian root may not be the best remedy for your condition. Seeing a doctor for a diagnosis can help you discover and treat the root cause of your insomnia. Cognitive behavioral therapy is a very effective treatment for insomnia that is not caused by an underlying medical condition.

Summary: Watch out for side effects. Know who shouldn’t take valerian root. Be cautious if you are taking other medications. Consider alternative therapies for insomnia.

For larger houses, try wrapping paper. For smaller houses, try scrapbook paper. Inside, it works as wallpaper and carpet. Outside, it can work as paint. Measure the size of the space, and cut the paper down to size. Smooth out the paper as you go. You can make flowers out of paper and create a yard or window box.  For a simple paper flower, cut out a round circle of paper. It should be about an inch across.  Cut out a simple spiral with two edges. Wave the lines as you cut. Beginning on the outside of the paper, roll up the spiral tightly. Once you've got it curled up, let it unravel slightly to form a flower. Glue the bottom of the spiral to the circle you made in the beginning.

Summary: Pick an appropriately-sized piece of paper. Use it to decorate the inside or outside of the house. Cut the paper to fit. Glue it into place. Add paper flowers to the yard.


Newton's second law of motion states that force equals mass times acceleration: F = ma. If you know the net force on the object, and it's acceleration, you can rearrange this formula to find the mass: m = F / a. Force is measured in N (newton), which you can also write as (kg * m)/ s2. Acceleration is measured in m/s2. When you calculate F / a, the units cancel to give you an answer in kilograms (kg). Mass is the amount of matter in an object; this does not change unless you cut off part of the object, or attach more material. Weight is a measurement of gravity's effect on mass. If you move the object to an area with different gravity (such as from the earth to the moon), it's weight will change, but it's mass will not. An object with more mass does weigh more than an object with less mass, if they're experiencing the same gravity. . If you're doing your chemistry homework, you may come across the term "molar mass." This is a related concept, but instead of measuring an object, you measure exactly one mole of a substance. Here's how to calculate it in most contexts:  For an element: look up the atomic mass of the element or compound you are measuring. This will be in "atomic mass units" (amu). Multiply by the molar mass constant, 1 g/mol, to put it into standard molar mass units: g/mol. For a compound: add the atomic masses of each atom in the compound to find the total amu of the molecule. Multiply this total by 1 g/mol.
Summary: Determine mass with force and acceleration. Understand mass and weight. Calculate molar mass
