Play the Oware strategy game against Tux
At the beginning of the game four seeds are placed in each house. Players take turns moving the seeds. In each turn, a player chooses one of the six houses under his or her control. The player removes all seeds from this house, and distributes them, dropping one in each house counter-clockwise from the original house, in a process called sowing. Seeds are not distributed into the end scoring houses, nor into the house drawn from. That is, the starting house is left empty; if it contained 12 seeds, it is skipped, and the twelfth seed is placed in the next house. After a turn, if the last seed was placed into an opponent's house and brought its total to two or three, all the seeds in that house are captured and placed in the player's scoring house (or set aside if the board has no scoring houses). If the previous-to-last seed also brought the total seeds in an opponent's house to two or three, these are captured as well, and so on. However, if a move would capture all an opponent's seeds, the capture is forfeited, and the seeds are instead left on the board, since this would prevent the opponent from continuing the game. The proscription against capturing all an opponent's seeds is related to a more general idea, that one ought to make a move that allows the opponent to continue playing. If an opponent's houses are all empty, the current player must make a move that gives the opponent seeds. If no such move is possible, the current player captures all seeds in his/her own territory, ending the game. (Source Wikipedia

Use the keyboard arrows to move Tux up to the door.
At the first levels, Tux walks comfortably, one step on each keypress, through the labyrinth.
For larger labyrinths, there is a special walking mode, called "run-fast-mode". If this run-fast-mode is enabled, Tux will run all the way automatically until he reaches a fork and you have to decide which way to go further.
You can see whether this mode is enabled or not, by looking at Tux's feet: If Tux is barefooted, "run-fast-mode" is disabled. And if he wears red sport shoes, "run-fast-mode" is enabled.
From level 14 on, run-fast-mode will be enabled automatically. If you want to use this feature in earlier levels or want to disable it in advanced levels, click on Tux or the "barefoot / sportshoe"-icon in the upper left corner of the screen to toggle the run-fast-mode.

Guide the Number Muncher to all the multiples of the number at the top of the screen.
The multiples of a number are all the numbers that are equal to the original number times another number. For example, 24, 36, 48 and 60 are all multiples of 12. 25 is not a multiple of 12 because there isn't any number that can be multiplied by 12 to get 25. If one number is a factor of a second number, then the second number is a multiple of the first number. Again, you can think of multiples as families, and factors are the people who belong to those families. The factor 5, has parents 10, grandparents 15, great-grandparents 20, great-great-grandparents 25, and every extra step of 5 is another great- in front! But the number 5 does not belong in the 8 or 23 families. You can't fit any number of 5s into 8 or 23 with nothing left over. So '8 isn't a multiple of 5, nor is 23. Only 5, 10, 15, 20, 25 ... are multiples (or families or steps) of 5. Use the arrow keys to navigate around the board and to avoid the Troggles. Press the spacebar to eat a number.
Help Tux escape the cave. Tux hides a number for you to find.
Read the instructions that give you the range of the number to find. Enter a number in the top right blue entry box. Tux will tell you if your number is higher or lower. Then enter another number. The distance between Tux and the escape area on the right represents how far you are from the correct number. If Tux is over or under the escape area, it means your number is over or under the correct number.

Find your way out of the maze (Move is relative)
Use the keyboard arrows to move Tux up to the door. In this maze, the move is relative (first person). Use the up arrow to go forward. The other arrows let you turn Tux in another direction.
At the first levels, Tux walks comfortably, one step on each keypress, through the labyrinth.
For larger labyrinths, there is a special walking mode, called "run-fast-mode". If this run-fast-mode is enabled, Tux will run all the way automatically until he reaches a fork and you have to decide which way to go further.
You can see whether this mode is enabled or not, by looking at Tux's feet: If Tux is barefooted, "run-fast-mode" is disabled. And if he wears red sport shoes, "run-fast-mode" is enabled.
From level 14 on, run-fast-mode will be enabled automatically. If you want to use this feature in earlier levels or want to disable it in advanced levels, click on Tux or the "barefoot / sportshoe"-icon in the upper left corner of the screen to toggle the run-fast-mode.

Understanding effect of mass and distance on orbital velocity.
A satellite revolves around the Earth because of the force between them. Orbital velocity of a satellite of Earth is directly proportional to the square root of the mass of Earth and inversely proportional to the square root of the distance from the center of Earth to the satellite.
In this activity, play with the speed of the satellite and mass of Earth to see what happens to the satellite. If the speed of the satellite is slower than the required orbital speed then the force applied by the Earth on the satellite is too much and thus the satellite gets pulled towards the Earth and burns in it's atmosphere. If the speed of the satellite is more than the required orbital speed then the Earth's force is not enough to keep it in orbit and thus the satellite flies away due to it's own inertia.
Copy the mirror image of an object from the box on the right into the box on the left.
First, select the proper tool from the toolbar. Then drag the mouse to create objects. When you are done, click on the OK button. A little red cross will show you where something isn't right yet. The order of objects (above/under) is not important but be careful not to end up with unwanted objects under others.

Guide the Number Muncher to all the factors of the number at the top of the screen.
The factors of a number are all the numbers that divide that number evenly. For example, the factors of 6 are 1, 2, 3 and 6. 4 is not a factor of 6 because 6 cannot be divided into 4 equal pieces. If one number is a multiple of a second number, then the second number is a factor of the first number. You can think of multiples as families, and factors are the people in those families. So 1, 2, 3 and 6 all fit into the 6 family, but 4 belongs to another family. Use the arrow keys to navigate around the board and to avoid the Troggles. Press the spacebar to eat a number.

Guide the Number Muncher to all the prime numbers.
Prime numbers are numbers that are only divisible by themselves and 1. For example, 3 is a prime number, but 4 isn't (because 4 is divisible by 2). You can think of prime numbers as very small families: they only ever have two people in them! Only themselves and 1. You can't fit any other numbers into them with nothing left over. 5 is one of these lonely numbers (only 5 × 1 = 5), but you can see that 6 has 2 and 3 in its family as well (6 × 1 = 6, 2 × 3 = 6). So 6 is not a prime number. Use the arrow keys to navigate around the board and to avoid the Troggles. Press the spacebar to eat a number.
The aim is to switch off all the lights.
The effect of pressing a button is to toggle the state of that button, and of its immediate vertical and horizontal neighbors. The sun and the color of the sky depend on the number of clicks needed to solve the puzzle. If you click on Tux, the solution is shown.
Direct your boat accurately to win the race.
In the text entry, enter one command per line, to control your boat.
Commands supported are displayed between the two entry areas. The 'left' and 'right' commands must be followed by an angle in degrees. The angle value is also called a 'parameter' to the left or right command. By default 45 degrees is used. The 'forward' command accepts a distance parameter. By default 1 is used.
For example:
- left 90: Make a perpendicular left turn
- forward 10: Go forward for 10 units (as displayed on the ruler).
The goal is to reach the right of the screen (the red line). When done, you can try to improve your program and start a new race with the same weather conditions by using the retry button. You can click and drag your mouse anywhere on the map to get a measurement in distance and angle. Going to the next level will give you more complex weather conditions.
