How to make a frog
You will need:
- square paper
- paints, pens or pencils for decorating
- a flat surface
1. Fold your paper in half to create a rectangle.
If you are using paper that is coloured on one side, make sure that the colour is on the outside when the paper is folded in half. Make sure all of the folds are well creased.
2. One at a time, fold the top corners of your rectangle down and then unfold them.
3. Turn the paper over. Squeeze the sides of the paper together, so your corner folds meet in the middle, and press down.
Your paper will now have a triangular top.
4. Fold the square bottom edge of the paper up to meet the base of the triangle.
5. Fold one flap of the triangle to the opposite side, creasing in the middle. Fold in the side of your paper to the middle. Unfold the triangle flap.
Repeat step five on the opposite side.
6. Fold the bottom edge of the paper up again to the base of the triangle and fold down the two top corners diagonally.
7. Unfold and pull the corners of the base out to make a boat-shaped flap.
8. Fold down the corners of the boat-shaped flap so they meet in the middle.
9. To make the frog’s legs, fold all four flaps upwards.
10. Fold the frog in half, then fold back the top edge.
11. Flip the paper over and you will have made an origami jumping frog.
12. Give your frog a face or decorate it as your favourite species using pens, paints, pencils or other decorations.
Decorate your frog
Although you can use paper that is sold specifically for origami, you can easily make an origami frog using any paper you have at home that is cut into a square.

How to Make an Origami Jumping Frog (with Pictures) – wikiHow
How to Make an Origami Jumping Frog (with Pictures) – wikiHow Download Article Download Article You can make a cute, springy frog using nothing more than a piece of paper and some folding skills. When you press down on the frog’s back, it really jumps! To make an origami jumping frog, start with a square of paper, then make a few simple folds. 1 Choose a piece of paper. You can use ordinary computer paper, colored paper, or origami paper. Traditionally, origami paper is square. However, you can start the frog with a piece of rectangular paper. Lay your piece of paper flat on a table in front of you. Origami paper can be found in craft, art, and stationery stores. 2Fold the top corners over the center of the paper. Fold the top right corner over diagonally, so that the tip of the corner touches with the opposite side of the paper. The top side of the paper should line up with the left side, forming a triangle shape. Press the fold with your finger to create a crease, then unfold it. Now do the same with the top left corner. Unfold the paper. You’ve now created a creased “X.” Advertisement 3 Trim the excess paper if you started with a rectangular piece. Fold the bottom edge of the paper up to make a crease that goes horizontally from one bottom end of the “X” crease to the other. Trim the excess below this crease with scissors or by carefully tearing it off. You’ll now have a square sheet of paper with the “X” crease in the middle. Remember to skip this step if you started with a square piece of paper. If you need help figuring out where to make the horizontal crease, go ahead and fold either the top left or the top right corner of your paper as you did in the previous step, to make a triangular shape. Trim the excess below the bottom edge of the triangular fold. Advertisement 1Fold the paper in half. Hold the paper on the table in front of you so that the bottom edge is facing you. Fold the top half of the paper horizontally, so that the two top corners meet the two bottom corners. Seal the fold with your finger, then unfold it. The new crease you’ve made should cross over the X, creating a pattern that looks like an asterisk or star. 2 Pinch in the sides to form a triangle. Center the paper on the table so that the bottom edge is facing you. Push the folds of the horizontal crease at the top of the paper toward the center. By pushing these folds inside the paper, the square will collapse into a triangle shape with two sides. To make the two sides fold inwards on themselves more easily, re-fold the horizontal crease you made in the previous step, but in the opposite direction. 3Fold one triangle corner upward. Place the triangle on the table so that the long edge is facing you. The long edge of the triangle divides into four points, two on each side. Take the top layer’s corner on the right side and fold it up. The tip of the corner should touch the tip of the triangle. Crease the fold with your finger. 4Move the opposite triangle corner upward. Take the top layer corner on the left…

Make an origami frog that really jumps! – It's Always Autumn
Make an origami frog that really jumps!In today’s post: Teach your kids how to make an origami frog that actually jumps! Origami jumping frogs are easy to fold and fun to play with. I couldn’t believe it when I realized last week that I had never taught my kids to make origami jumping frogs. I learned how to fold these in sixth grade from a friend, and we had a blast making frogs of all sizes and colors, then seeing whose frog could jump the furthest and who could get her frog to land on it’s feet most often. These cute little origami frogs are pretty easy to fold, so most upper elementary age kids will have no trouble with them. My six year old was even able to make one with a little help. Keep reading for full instructions on how to fold your own jumping origami frog. Origami frog: supplies As with most origami, these frogs are a little easier to fold if you have actual origami paper, since it’s nice and thin, but you can really use any square piece of paper. Find origami paper here: reasonably priced 120 sheet pack on AmazonOrigami paper options at Target, including cool patterned paper Once your frog is folded, press down on the folded “legs” with the tip of your finger, then quickly slide your finger off to make the frog jump. Depending on how hard you push the legs down, you might be able to get the origami frog to make one perfect flip in the air and land on its feet again. It’s fun to try to jump the frogs into targets, or just see whose frog jumps the furthest. How to fold a jumping origami frog I’ve made photo diagrams as clear as possible so I don’t have to try to explain each step. When you see arrows, those are showing you which direction you should fold the paper, and the dotted lines show you the line the fold will make. Remember, you are not folding to match the paper up with the dotted line, you are folding ON the dotted line. For these frogs, we used 6 inch square origami paper, and the frogs ended up about 2×2 inches.

How a Frog Became the First Mainstream Pregnancy Test
How a Frog Became the First Mainstream Pregnancy TestThe African clawed frog, Xenopus laevis, is a palm-sized, greenish-gray animal that hails from the ponds and rivers of sub-Saharan Africa, where it lived for millions of years without anyone injecting it with urine. That unbroken streak changed in the 1930s, thanks to a British scientist with the fantastic name of Lancelot Hogben.Hogben was a talented but irascible zoologist with strident left-wing politics and penchant for burning bridges. In his early career, he studied hormones by injecting them into frogs, and when he moved to South Africa in 1927, he continued those experiments with the local amphibians. One of them—Xenopus—was so abundant and easy to work with that Hogben spent much of his time with the creature, and even named his house after it.In 1930, Hogben injected Xenopus with extracts from an ox’s pituitary gland—a pea-sized hormone factory at the base of the brain. In response, the frog started laying eggs. This accidental finding was a fortuitous one. At the time, scientists knew that the urine of pregnant women contained hormones that were made in the pituitary and that affected the development of ovaries. If those same hormones could trigger egg-laying in Xenopus, perhaps the frog could act as a living pregnancy test.Hogben never alluded to this application in his early reports, but it wasn’t long before he was working towards it. Disenchanted with racism in South Africa, he returned to Britain shortly after his seminal experiments and brought a colony of Xenopus with him. His colleague Charles Bellerby worked out how to raise the frogs appropriately, showed that they would reliably lay eggs when exposed to the urine of pregnant women, and confirmed that when they’re not mating, they don’t lay eggs spontaneously. Another team from South Africa had been doing similar work, and as academics are wont to do, the two groups developed a bitter feud. It was never truly resolved, although Hogben could be said to have won, since the test that resulted from this work took his name.The “Hogben test” was simple. Collect a woman’s urine and inject it, fresh and untreated, under the skin of a female Xenopus. Then, wait. If the woman is pregnant, between five and 12 hours later, the frog will produce a cluster of millimeter-sized, black-and-white spheres. The results were reliable. One researcher reported that after injecting 150 frogs, he never got any false positives and only missed three actual pregnancies. And as one doctor wrote to Hogben’s colleagues: “Thank you for your report on the pregnancy test on Mrs. X. You may be interested to know that of one GP of many years’ standing, one specialist gynaecologist and one frog, only the frog was correct.’”There’s a long history of folk pregnancy tests: As my former colleague Cari Romm once wrote, “a long, long time before women peed on sticks, they peed on plenty of other things.” But the first reliable test was created in 1927 by German scientists Bernhard Zondek and Selmar Aschheim. Their “A-Z test” involved injecting human urine into immature female mice for a few days, dissecting the animals, and checking if their ovaries were bigger than normal.A later version of this test used rabbits instead of mice. For some reason, people came to believe that the rabbits would die if the…

Attracting frogs and toads – State of Michigan
Attracting frogs and toads Although most of Michigan’s amphibians are small and secretive, with just a little effort you can create a haven for them in your own yard. Here are a few suggestions: Leave some leaf litter under your trees, shrubs and in the garden. Encourage native ground cover, grasses and wildflowers; a finely manicured lawn is attractive to people but not to most frogs and toads or other wildlife. Build a shallow pond that includes natural pond vegetation and rocks in and around. For more details call the number above. Erect a toad light. A toad light is a light that is set no higher than 3 feet and is placed near a border between a garden or rockery and a lawn area. The light attracts insects on which the toads feed at night. Try to discourage children and others from capturing and caging frogs and toads in your yard and elsewhere. Minimize the use of pesticides and fertilizers in the yard. For more information, view the “Frogs, Turtles & Snakes” chapter in Managing Michigan’s Wildlife: a landowner’s guide.
The Frog Life Cycle – Developmental Biology – NCBI Bookshelf
The Frog Life CycleFigure 2.1 uses the development of a frog to show a representative life cycle. Let us look at this life cycle in a bit more detail. First, in most frogs, gametogenesis and fertilization are seasonal events for this animal, because its life depends upon the plants and insects in the pond where it lives and on the temperature of the air and water. A combination of photoperiod (hours of daylight) and temperature tells the pituitary gland of the female frog that it is spring. If the frog is mature, the pituitary gland secretes hormones that stimulate the ovary to make estrogen. Estrogen is a hormone that can instruct the liver to make and secrete the yolk proteins, which are then transported through the blood into the enlarging eggs in the ovary.* The yolk is transported into the bottom portion of the egg (Figure 2.2A).Figure 2.2Early development of the frog Xenopus laevis. (A) As the egg matures, it accumulates yolk (here stained yellow and green) in the vegetal cytoplasm. (B) Frogs mate by amplexus, the male grasping the female around the belly and fertilizing the eggs as they (more…)Another ovarian hormone, progesterone, signals the egg to resume its meiotic division. This is necessary because the egg had been “frozen” in the metaphase of its first meiosis. When it has completed this first meiotic division, the egg is released from the ovary and can be fertilized. In many species, the eggs are enclosed in a jelly coat that acts to enhance their size (so they won’t be as easily eaten), to protect them against bacteria, and to attract and activate sperm.Sperm also occur on a seasonal basis. The male leopard frogs make their sperm in the summer, and by the time they begin hibernation in autumn, they have all the sperm that are to be available for the following spring’s breeding season. In most species of frogs, fertilization is external. The male frog grabs the female’s back and fertilizes the eggs as the female frog releases them (Figure 2.2B). Rana pipiens usually lays around 2500 eggs, while the bullfrog, Rana catesbiana, can lay as many as 20,000. Some species lay their eggs in pond vegetation, and the jelly adheres to the plants and anchors the eggs (Figure 2.2C). Other species float their eggs into the center of the pond without any support.Fertilization accomplishes several things. First, it allows the egg to complete its second meiotic division, which provides the egg with a haploid pronucleus. The egg pronucleus and the sperm pronucleus will meet in the egg cytoplasm to form the diploid zygotic nucleus. Second, fertilization causes the cytoplasm of the egg to move such that different parts of the cytoplasm find themselves in new locations (Figure 2.2D). Third, fertilization activates those molecules necessary to begin cell cleavage and development (Rugh 1950). The sperm and egg die quickly unless fertilization occurs.During cleavage, the volume of the frog egg stays the same, but it is divided into tens of thousands of cells (Figure 2.2E-H). The animal hemisphere of the egg divides faster than the vegetal hemisphere does, and the cells of the vegetal hemisphere become progressively larger the more vegetal the cytoplasm. A fluid-filled cavity, the blastocoel, forms in the…
