Water bears suck out juices from moss, algae, and lichen to feed. Put a bit of plant matter in once a month, or replace the old stuff if it starts to turn moldy or decompose.  Water Bears also eat nematodes, little worm-shaped creatures, and rotifers, tiny plankton. Try to find nice, wet moss for the Water Bears as that is most likely to contain their prey. Some tardigrades live in freshwater and others live in saltwater. Stick to water and plants from the same type of environment where you collected your tardigrades. Tardigrades will usually survive in a dry state, but it's not guaranteed. Be nice to your water bears and keep them wet. Dried out tardigrades are smaller and completely immobile. You might not be able to spot them, but you'll see them again if you give them a good soak. They won't mind if you look at them under the microscope once in a while. If you're lucky, you might see them shedding their hard outer cuticle, laying eggs, or hatching.

One-sentence summary -- Feed the tardigrade. Replace the water in the petri dish once it dries out. Enjoy caring for tardigrades.


Washing your hair everyday can negatively impact your hair's health and slow down the hair grow. Try to only shampoo when your hair needs it. This might be every two to three days or even just once a week. This allows your scalp's natural oils to get into the follicles and stimulate growth. Many people believe that trimming your hair slows the rate of your hair growth. Others think you should trim it every six weeks. You should trim your hair when you have unhealthy split ends. Trimming the dead, damaged split ends can help promote better hair growth. You can trim your hair every three to four months, as long as you don't have split ends. If you notice split ends, get your hair trimmed as soon as possible to prevent the split from moving up the shaft and causing more damage. Massaging your scalp may help promote faster hair growth. Massaging your scalp helps promote follicle health by increasing the blood flow to your scalp, which can help the hair grow. Once a day, massage your scalp for three minutes before you wash it. Try using peppermint or eucalyptus oil diluted with coconut oil to massage your scalp. Styling your hair too much or with harsh products and instruments can slow the growth of your hair and cause your hair to become unhealthy. Be gentle with your hair, especially when you are trying to grow it out. For example, try not to blow dry, use heating tools, perm, or color too often. When trying to make your curly hair grow faster, you should protect it at night. Seal the ends of your hair with oil before going to bed. Try coconut, olive, or jojoba oil. Try sleeping on a satin pillowcase to help prevent damage during the night. You may consider pulling your hair back into a loose ponytail, braid, or bun while you sleep.

There is a lot of information available about the effects of secondhand smoke, and how children might come in to contact with it. Before being able to truly protect your children from its negative effects, you need to understand the different ways they might be exposed to it. There is a lot of information available, a few examples of what you might find include:  No amount of secondhand smoke exposure constitutes a safe amount.  Infants who are exposed to secondhand smoke are at greater risk of dying from sudden infant death syndrome (SIDS).  Short-term effects of exposure to secondhand smoke on children include more frequent ear infections, more frequent coughs and colds (and longer recovery times), as well as tooth decay.  Long-term effects include greater risk of lung cancer and heart disease, as well as poor lung development. While you are likely to find everything you need to know on the internet, if you want to read the scientific studies that discover how secondhand smoke effects children, try searching in scholarly databases. Google Scholar offers a good way to search for scholarly literature. The advantage of reading these peer reviewed articles is that you are getting the information from the source, rather than an interpretation. Many states offer free hotlines where you can request information about tobacco use and support for those wishing to quit.

The amount of charcoal will vary based on the size of your grill, but a good rule of thumb to follow is to add enough to form two layers on the bottom of the grill. Once you've added enough, stack the charcoal into a cone or pyramid shape in the center of the grill. Check your bag of coals to see if they require lighter fluid or if they are pre-treated. If they require lighter fluid, carefully pour it onto the cone of coals, focusing on the center. The amount of lighter fluid you should use will vary, but a good approximation is adding 1/4 cup (60 ml) of fluid per 1 lb. (450 g) of charcoal.  If your coals are pre-treated with lighter fluid, you don’t need to add additional lighter fluid. Allow the lighter fluid to soak into the coals for approximately thirty minutes before lighting. Use long fireplace matches to light the cone. Light several areas of the coals to ensure that the fire takes to the whole pile. You can discard the matches directly into the grill if desired. Allow the coals to burn until they are all grayish-white on the surface. Use a long-handled instrument, such as a pair of tongs. Put the grate into place and close the grill’s lid. Let the coals burn until the edges turn grey. This should take about five-to-ten minutes.
