Modeling and Diagnosis of Friction and Wear in - DiVA
You might need a friend to help you with this part. To get your craft to start hovering simply put the CD on a smooth, flat surface and pop the top open! Use a clock to measure how long the balloon will stick to an object. Try this several days apart to see the effect that weather or humidity has on the length. Make a chart listing the time and the weather. Draw some conclusions.
Grab a balloon to explore concepts of static electricity such as charge transfer, attraction, repulsion, and induced charge. Sample Learning Goals Describe and draw models for common static electricity concepts (transfer of charge, induction, attraction, repulsion, and grounding) They noticed that a pebble slid faster then their mitten because there was less friction with the pebble. The experiment we did together helped them to understand their world and things they play with on a daily basis. I love the fact that this experiment for kids is hands-on and play based. Children learn as they play and experiment. In this experiment you will test if the number of rubs can change how long the static charge will last by rubbing a balloon with wool and timing how long it will cling to a wall.
Larsson (2013) studied four children's exploration of friction during their days at a preschool. The children explored friction in everyday activities, sometimes in experiments now performed in order to increase the water friction at the ground or sea surface gives rise along the trajectory of such balloons undoubtedly.

Wad one of the pieces of paper into a ball. Se hela listan på carrotsareorange.com Cool Experiments with Friction from JDaniel4’sMom. This activity is similar to the above but gives additional ideas for exploring different surface tensions with cars and ramps.

Rub each balloon with the same material to charge it. The air escaping from the balloon creates thrust and causes there to be a cushion of moving air between the disk and the table top.
It’s a very cool experiment using a light bulb and a balloon. Hovercraft & Friction Experiment by Rookie Parenting Unpoppable Balloon Experiment by Deceptively Educational Balloon powered Sponge Boat by The Craft Train Pop a Balloon with an Orange Peel by Raising Dragons
Pour rice into a bowl for easy access. Place the funnel into the bottle.

Hold the balloon between your hands and move it in a circular motion until the hex nut starts to roll around the inside of the balloon. Now stop moving the balloon and watch what happens to the hex nut. 2011-12-16 Drag the hovercraft along the ground with the balloon deflated. Blow up the balloon and do the same thing. Why is it easier to move when the balloon is inflated?
