Imperfect Balance 2 is an addicting physics-based game for kids & teens where you have to use your knowledge of balance and gravity to succeed. This fun game might make you question your own mental stability! Science has never been such wobbly enjoyment! This game is the exact opposite to the popular Perfect Balance game. The goal with this version is to make as many blocks and shapes fall off the screen as possible!

It’s fun to watch them fall (until they get stuck, that is!). Have a go – see if you can handle the delicate demands of gravity. You have to use the available geometrical figures (balls, squares, triangles, etc.) in a certain order and position in order to make all the pieces/shapes fall out off the game screen (by employing gravity).

It sounds simple but it can become a very fiddly task! It’s difficult to make all pieces and shapes fall (without leaving any standing and intact). Also, some of the pieces often get stuck and are very difficult to move (leaving you with a poor score). Plan your moves ahead! You don’t want to get any pieces stuck! With a high total score, you can unlock the next Level Pack.

You don’t need to beat every level completely to be able to continue, just make as many colorful blocks as possible fall off the screen. You can also destroy colorful blocks by other means (bombs etc.) A bomb destroys all but glass blocks. You earn 1 point for every colorful block that falls off the screen and 3 points for each block that is in the shape box when you have cleared the Playfield. A perfect strike gives you 5 extra points.

Imperfect Balance is the complete opposite to the Perfect Balance game. Also, it may initially look like a much simpler task. For example, what could be easier than putting everything the wrong way so to make it fall down?  In fact, this is just a first impression. This addicting physics-based game, at times, is even more complicated when compared to its predecessor – Perfect Balance. The problem is to make all pieces and shapes fall (without leaving any standing). And when most of the pieces fall down easily, others get stuck for good, leaving you with a poor score.

You have to use limited geometrical figures (balls, squares, triangles, lines and some “force” objects) in a certain order and position in order to to make each and every piece/shape fall down through the force of the gravity. Your knowledge of geometry and physics finally can be used in practice – just by playing this game. Test yourself!

Love a really difficult physics-based puzzle activity? Ramps is a highly-stimulating, interactive physics game (for older middle school age kids, high school students, and grown-ups) that will thoroughly test your analytical thinking skills and problem solving tenacity levels. It is based on the relationship between potential energy (stored energy - ready to go) and kinetic energy (the energy of motion), and how your understanding of these two energies can greatly enhance your chances of success. In simple terms, you have to use a set of rotatable ramps to guide a dropping sphere into an awkwardly-placed bucket in each level. You play the role of ‘Ramp Builder’, and have to strategically position your limited number of ramps throughout the game screen so that they create a route or bridge structure for the descending blue sphere to travel along. Points are earned based on number of spheres used in each level, the time taken to solve the level, and the difficulty of the level.

This challenging and innovative online brain teaser activity requires total concentration, great patience, and the ability to predict the bounce and velocity of a falling sphere. You also need to call upon your creative engineering side as you carefully construct a platform that guides your sphere in the desired direction. Close observation, and trial and error are essential keys to success, so ensure that you keep trying different ramp combinations, and the solution should "hopefully" reveal itself to you with time! Happy channel building!

Balance Zone is a simple, physics-based game and online problem solving activity for kids & teens where you have to test and use your knowledge of balance and gravity to succeed.  Your mission is to make two Scales balance in the special ‘Balance Zone’ by strategically placing differently shaped blocks on them.  Each of the ten levels can only be completed by keeping the Scales balanced in the Zone (the darker grey background) for 8 seconds. 

This game is designed to test any budding Physics Whizz, and requires a basic understanding of science – gravity, mass, geometry and how balance-beams work.  This brain-teaser is based on the laws of gravity – meaning that the blocks can easily fall off the Scales if you’re not careful.  Have a go – see if you can handle the delicate demands of gravity and show off your engineering talents!
 
How to Play: Using your computer mouse, click and drag the colorful blocks from the right hand side of the game screen to the two Scales in the center.  You can stack blocks either on top of each other, or side by side.  Carefully position the blocks so that the Scales are balanced in the Balance Zone (when this happens, the clock starts ticking).  If the Scales stay in the Zone until the clock runs out, you progress to the next level. You don't have to keep the scales perfectly balanced - just as long as they remain in the Zone Area for the time it takes the clock to go around. Happy balancing!

Tips: You don’t have to put every block on the platforms to make them balanced.   You can leave some of them off to the side. Try different combinations of blocks on each of the scales until you get it right. Also, add up the number of squares on each block to compare the weight of each, and then try to get an equal amount of squares on each scale for better balance.

Lever Physics is a challenging, math, physics and equilibrium-based game for upper elementary school / middle school students, high school teens and grownups where you must place and balance weights (fun items and characters) on a ‘seesaw-style’ beam connected to the ground by a pivot (fulcrum). Playing against the clock, you must place any available weights onto the lever (beam), and try to keep it perfectly balanced in the middle.

Some quick physics revision: A lever is a simple mechanical device which consists of a beam or stick or rod, and helps to lift weights with less effort. To be effective (as a lever), it must have a support to pivot on. This pivot is called a fulcrum. Levers can then be used to exert a large force over a small distance at one end of a structure by exerting only a small force over a greater distance at the other end of the same structure (beam). (Physics teachers - Brief correction welcome here if needed..!)

The Law of Equilibrium: A lever is in equilibrium when "the load" and "the effort" balance each other. The effort (weight) multiplied by its distance from the fulcrum = the load (weight) multiplied by its distance from the fulcrum. This law of equilibrium is true for all classes of levers.

For example, 2 pounds of effort exerted 4 feet from the fulcrum will balance 8 pounds located 1 foot on the other side of fulcrum. This effort times (multiplied by) distance about the fulcrum is the "Torque" (rotational force).

Back to Lever Physics Flash game!: Don't be fooled by the fun and playful imagery in this load balancing brain-teaser! It is a tricky, analytical thinking puzzle and logic problem solving challenge that requires good observation skills and hard thinking combined with mathematical and engineering solutions.

This interactive, point-and-click activity allows some trial and error (by quickly placing, removing and re-positioning weights) but you definitely cannot delay your decisions for long as the clock is ticking fast! Ok Balancing Master, can you ‘lever’ yourself to the top of the class?
