How to make schools science laboratories safe

Science laboratories are an important part of schools and colleges. Science lab experiments provide a better understanding of the different concepts and theories of science to students. Science labs foster interest and make science interesting and fun for kids. But science laboratories are dangerous too. Even simple mistakes can lead to serious injuries and damages. It is the duty and responsibility of school authorities to create a safe science lab environment.

There are several things that schools must do in order to create a safe lab environment for their students. Schools must ensure that all the personnel are highly trained. The teachers, supervisors, and lab assistants must possess thorough understanding of all the chemicals, hardware, and lab equipment.

They must supervise the students while they are conducting science experiments and should never leave them unattended. Science teachers should ensure that students follow each and every step as given in the science text book as small diversions can lead to major reactions.

It is important to avoid all sorts of distractions in the science laboratories. Teachers and assistants should closely monitor the students to ensure that they do not use their cell phones or listen to music while in lab. A lot of times, accidents occur because attention drifts.

Science lab wear are equally important. They help prevent fatal accidents and minimize the danger of exposure to obnoxious fumes and chemicals. Students must be made to wear laboratory coats, aprons, protective eye wear, and hand gloves when performing experiments in chemistry labs, physics labs and biology labs.

There should be an eyewash and hand wash station in every science laboratory to provide first-aid solution in case students accidentally expose their eyes or any body part to harmful chemicals. Science laboratories must be fitted with proper air ventilation to prevent fatal inhalation of toxic gases and substances.

School authorities must perform safety inspections from time to time. Lab managers must inspect all the laboratory supplies and lab safety equipment and should replace all worn out damaged equipment immediately. If any chemicals or other lab substances and supplies have expired or have aged, they must be discarded and should be replaced with safe, new, and top quality supplies.

Likewise, it is the duty of the lab assistants to check test tubes, beakers, flasks, funnels, pipettes, spoons, and other glass lab ware to ensure that they are not cracked or damaged. Cracks in glass ware can cause the chemicals to leak and may also cause the glassware to break accidentally when exposed to heat.

It is advisable that school authorities maintain records of any minor or major accidents that take place in science laboratories. By recording them and tracking them, schools can formulate the protocol that will help prevent similar instances in future and can create a safe lab environment for their students.

Follow the safety procedures discussed above to provide safe, enjoyable, and effective science laboratory environment for your students.

Essential Features to Look For While Buying A Human Anatomy Model

Human anatomy models are mostly preferred by schools and colleges so that an idea about various human organs can be rendered to the students. Anatomy models of each and every part of the body are available in various shapes and sizes and can be easily found online. While buying a particular anatomy model, there are certain features that are to be considered.

A few of the essential features to look for in a human anatomy model:

  • Anatomy models must be invested upon depending on the age group of students. For instance, for the younger group of students, choose a large scale models of the organs. This will help to attract the attention of the students more toward the model.
  • Ensure that the model is imparting correct details of each model. The details are essential to give right education to students with the help of these models.
  • These models are made with keeping the concept of children in mind, they are also sturdier than the conventional ones. Hence they are able to withstand any rough handling by young students.
  • Another feature to be considered is the level of knowledge of the target students while choosing a particular anatomy model. For instance, human anatomy models with more and accurate details must be chosen for teaching medical students.
  • The anatomy models specifically constructed keeping in mind the medical students are more versatile just like the real organs available. This is essential as the students need to know exactly what type of organ they are dealing with.
  • You will also find miniature products that are easily accommodated in the desk. This type of models are usually preferred by various medical professional for placing them in their offices or clinics. So, these types of models portray very less details pertaining to the organs in that model. Doctors can employ those models as a quick reference in order to explain a condition in detail to the patient.
  • While buying the human anatomy models, consider the cost factor, as well. You can easily find good quality anatomy models at an affordable price that will solve your purpose.

Besides, human anatomy models, there are models for other animals, as well. These act as a great platform for learning for your kids. Just remember the points mentioned above for buying a good anatomy model for students or your children.

Paper Clip On Water: A Simple Science Experiment For Kids

Learning becomes fun and lot more effective with the help of science experiments. Here is one exciting science experiment that you can conduct at home or in school to make kids understand why and how paper clips float on water.

For this science experiment, you would need paper clips, a bowl of water, tissue paper, and a pencil and eraser.

Now fill the bowl with water. Take a piece of tissue and gently drop that onto the surface of water. Without touching the water or the tissue, try to place a dry and clean clip onto the tissue. Take a pencil to slowly poke the tissue until it sinks down into the water. It may take some effort but the tissue will sink and the paper clip would be left floating on the water.

Kids would be surprised to see the paper clips floating on the water. How does it really happen?

The scientific theory behind this is known as surface tension. There is a kind of skin on the surface of water which holds the water molecules tightly. This surface tension also holds the paper clip which can otherwise not float on the water.

If you place an insect such as a water strider on the water, you would notice that it would walk on the water. The insect uses this skin to walk over the surface of the water.

You can use this science experiment for finding out many other interesting things, such as how many paper clips can the surface tension hold? Does the floating ability of the paper clip depend on its shape and size? How can the surface tension of the liquid be made stronger? Do all liquids have the same surface tension?

To conduct this and many more exciting and experiential science experiments at home or school, you can buy science kits.

Let your kids enjoy learning science!!

All About Cleaning and Maintaining Laboratory Glassware

Even the most carefully executed experiment can give erroneous results if dirty glassware is bought to use. If the glassware that is used for measuring liquids is contaminated with grease and other materials, it prevents the glass from being uniformly wetted. This in turn will affect the volume of liquid delivered and the amount of residue adhering to the walls of the container. Likewise, presence of impurities in glass labware can distort the meniscus and can prevent one from getting the correct results out of the science lab experiment.

Keeping the laboratory glassware physically neat and clean, free of grease, and bacteria is therefore of the utmost importance.

To keep your glass labware neat and clean, you must wash it immediately after use. Put glassware in water if you can not clean it immediately otherwise the residue will stick to the labware and it would get difficult to remove it.

For washing the glass labware, make use of soap, detergent, or cleaning powder. Try to use soap and cleaning powder without any abrasives as it can scratch the glass. However, for glassware that is too dirty, you can make use of cleaning powder with mild abrasive action to get good cleaning results. Chromic acid solution is quite effective in cleaning unduly clouded or dirty glassware. For scrubbing the glassware thoroughly, you must use a brush.

After cleaning, rinse the glassware with tap water. Allow the water to run into and over the glassware and then fill each piece with water. Fill test tubes, flasks, and other glassware with water and shake and empty them. Do this for at least 5-6 times to clean the glassware properly. For cleaning contaminated glassware, you will have to sterilize them too.

Washed labware must either be placed in a basket with their mouth downwards for allowing them to dry completely or they should be made to dry in an oven. You can also hang test tubes, flasks, and other labware on wooden pegs for drying them out. Stand dry cylinders, burets, and pipets on a towel for drying them properly.

Place clean glassware in a cabinet to protect it from dust. You can also make use of cotton, or cork, or can tape a piece of paper on the mouth of the glassware to prevent dirt and dust from entering the glassware. Keep washed, cleaned, and sterilised glassware pieces in special racks and at a distance to avoid any breakage.

With proper care and maintenance you can not only increase the life of your labware, but can also enhance your lab safety.

Things You Need To Know About A Refractor Telescope

You may be having a refractor telescope in your schools science lab and you might have used it couple of times to teach astronomical facts to your students. Here are some interesting things that you should know about refractor telescopes and should share the same with your students.

  • The first refractor telescope was invented by Hans Lippershey, Zacarias Janssen and Jacob Metius and it was made in 1608 in Netherlands.
  • Galileo was the first person who used the refractor telescope in 1609. He modified and re-oriented the design elements of the telescope made by Lippershey and came up with his own version.
  • The refracting telescope invented by Galileo was less than 2 inches. Today, however one can find telescopes varying in length, ranging between 1 and 5 feet.
  • The length of refractory telescope lenses is not more than 8 inches.
  • In 1733, a newer and better version of the refractor telescope was invented. It was named achromatic refractor telescope and was invented by Chester Moore Hall.
  • The Galilean refractor telescope is not considered to be as reliable as they distort the images quite easily. It is believed that one sees false colors or a rainbow coloured ring of light around the outer edge of the planets when using earlier model of refractor telescope.
  • In order to overcome these problems, Johannes Kepler invented a new and better telescope. The refractor telescope invented by him utilized convex eyepiece as opposed to the concave eyepiece used in the Galilean telescope model.
  • A refractor telescope consists of a tapered tube and a lens placed inside either end of the tube. The larger lens is a convex piece of glass. It directs light to a central image inside the tube and the smaller lens is the eyepiece, which magnifies the image.
  • Refractor telescopes are closed tubes and therefore do not get dust, and other elements. It is quite easy to maintain these telescopes.
