How can we solve the problem of frogs?
To move a frog (either a Slide or a Jump), you just need to click on that frog. This is not at all obvious, but it turns out that there is only one solution to the problem if the green frog moves first, and only one solution to the problem if the red frog moves first.
How can a frog float on a lily pad experiment?
A resting frog can deform the lily pad on which it sits. The weight of the frog applies a localised load to the lily pad (which is supported by the buoyancy of the liquid below), thus deforming the pad.
How do frogs interact with lily pads?
If a pond has water lily leaves floating in it and they are the closest available perch, frogs will climb up on them readily. However, if the frog is heavy, the leaf will sink beneath him a little bit, enabling the frog to keep his skin moist in the water while still perching on the submerged leaf.
How do you solve 6 frogs on cool math?
Your goal is to get all six frogs to cross the pond. The blue frogs need to get to the left side, and the green frogs need to get to the right side. Click on a frog to make it hop forward one rock or jump over another toad.
What characteristics make the water lily float on water?
Water lilies are well equipped for life in the water, with a stem structure that contains a tough network of bundled hollow cells that hold air and help stems float. Once leaves unfurl, their large surface area offers the plant additional support by using water surface tension to keep the plant afloat.
What is the adaptation of water lily?
Water lilies have a number of adaptations that help them survive in water, including big leaves that float on the water’s surface to attract ample sunlight for photosynthesis. The top side of the leaf is covered with a cuticle to keep it as dry as possible, and the underside has thorns to protect against predators.
Why do frogs sit in the sun?
They believe that the frogs’ unusual skin is allowing the animals to bask in hot sunlight, possibly boosting their temperatures to kill off the fungus. They sit in the Sun and bask for long periods without doing themselves any harm. Most frogs avoid prolonged exposure to sunlight; the light and heat dry out their skin.
Why do frogs sit still for so long?
Because their eyes are situated at the top of the head, species that spend much of their time in water can sit motionless with only their eyes above the surface. All the better for watching for unwary insects they can eat.
How do you do the leap frog puzzle?
Click on a frog to make it jump forward. A frog can jump a maximum of two spaces, and the destination spot must be free. Green frogs can only hop to the right. Brown frogs can only hop to the left.
What is the main idea of the story of the water lily?
One of the main themes in Waterlily is that kinship was the foremost important aspect of Sioux society. Kinship ties were an obligation and were dominated by strict social rules, which determined the appropriate degree of interaction between individuals.
What is the characteristics of water lily roots?
Most species of water lilies have rounded, variously notched, waxy-coated leaves on long stalks that contain many air spaces and float in quiet freshwater habitats. The stalks arise from thick, fleshy, creeping underwater stems that are buried in the mud.
How do lily pads grow?
They grow from tubers planted in pots beneath the water and send up stems with rounded leaves and star-shaped blossoms that float on the surface. Water lilies bloom in a variety of colors including pink, white, yellow, and red.
Can frogs jump over lily pads?
Imagine two red frogs and two blue frogs sitting on lily pads, with a spare lily pad in between them. Frogs can slide onto adjacent lily pads or jump over a frog; frogs can’t jump over more than one frog.
Can Red Frogs and blue frogs jump over each other?
Imagine two red frogs and two blue frogs sitting on lily pads, with a spare lily pad in between them. Frogs can slide onto adjacent lily pads or jump over a frog; frogs can’t jump over more than one frog. Can we swap the red frogs with the blue frogs? Experiment with different numbers of red and blue frogs.
How many frogs are there in the Lilypad?
There are two blue frogs and two red frogs. A frog can jump over one other frog onto an empty lilypad or it can slide onto an empty lilypad which is immediately next to it. Only one frog, at a time, is allowed on each lilypad.
How many lily pads are covered by jumps?
This covers two lily pads. There are 9 ‘meetings’ so there are 9 jumps, which means that 18 lily pads are covered by jumps. Finally, 24 – 18 = 6. This means that there are 6 lily pads still to be covered. They can’t be covered by jumps because we have accounted for all of the jumps.
