The water was then allowed to flow through selected test pipes. The water was then allowed to flow via the connector in the channel placed on the desk via the flexible connecting hose, as illustrated in Figure 1. Figure 3 describes various parts of the experimental setup.įigure 2 Fluid friction Experimental Setupįigure 3: Experimental Setup Diagrammatic Representation (Buchholz et al., 2019) ProcedureĪ centrifugal pump mounted on the inside of the hydraulics bench was used to pump water through the Fluid Friction Apparatus. The apparatus and equipment were as illustrated in Figure 2 and Figure 3. A manometer connected to pipes for reading the pressure difference between the pipes.An elbow and expansion and a constriction pipe for minor head losses.The experimental system is set up on a hydraulic bench to ensure facilities for volumetric measurements and water supply are on the bench. Ensure the lab assistant supervises any change made in the experimental procedure or design before undertaking any experiment. Additionally, the experimenter should also ensure that he or she does not utilize the submersible pump when the tank is empty. The apparatus uses high voltage electricity hence, it requires a lot of careful handling of electrocution or electric shock. The transition stage is represented by the section circled, in which there is no proper relationship between V and H. The most important thing to is, head losses due to turbulent flow is more sensitive to velocity (Haddad, 2019).įigure 1: Relationship of head loss and velocity (Cerbus et al., 2017) On the other hand, turbulent flow can be defined as a head loss that is directly proportional to the sum of velocity power that is Where k is a constant and v is the velocity Kids have fun and make a really cool machine on top of it.A laminar flow refers to a flow in which a head loss is directly proportional to the velocity of the flow. Explore Newton’s 3rd Law of Motion with this activity!ĭoes science get any cooler than making a hovercraft? You will be hard-pressed to find a more engaging and easy friction experiment. The best part is how mesmerized children are by being able to pick up a bottle of rice with a chopstick alone. Does it get any easier than a bottle, rice, and a chopstick? Okay, there is a funnel involved in the experiment, also. One of outnumbers all-time favorite science lessons of all time. Kids love this activity and it includes a worksheet to bring the friction learning home. It demonstrates friction in a fun and cool way. I love this activity for so many reasons. This science activity integrates math and other less tangible skills such as focus and concentration by completing the activity! I love the textures used in this friction activity! This activity completes the learning circle by making predictions, noting observations, and examining the results. This activity is similar to the above but gives additional ideas for exploring different surface tensions with cars and ramps. So, why not introduce a little science learning with a friction activity? This science lesson involves mostly things from around the house, too, which is always a bonus!Ĭool Experiments with Friction from JDaniel4’sMom What a cool and easy way to experiment with friction! Kids love cars and ramps. Below are my favorite and super cool friction activities for kids.Įxploring Ramps & Friction from Pre-K Pages If there were absolutely no friction between your feet and the ground, you would be unable to propel yourself forward by running, and would simply end up jogging in place (similar to trying to run on very slippery ice).” Friction Experiments for Kidsįriction experiments are some of the easiest, inexpensive, and most enjoyable for kids. We call this “grippy” type of friction, where the surfaces are prevented from slipping across each other, a static frictional force. Your planted foot can grip the ground and push backward, which causes the ground to push forward on your foot. This is the same force that allows you to accelerate forward when you run. “The force of static friction is a force between two surfaces that prevents those surfaces from sliding or slipping across each other. This explanation from the Khan Academy is terrific so I will borrow it: Check out these experiments on friction for tons of learning fun!įriction is part of the science of physics. You’ve created a lifelong scientist! Exploring science rarely takes many out of the ordinary materials, often materials you can find around your home. Get kids moving and involved in the science lesson and you’re on your way. Hands-on science experiments are even better. Science activities engage and intrigue kids in ways not possible by other topics.
