🐙🦋 Welcome to Happy Learning’s live session on invertebrates and insects! In this exciting educational livestream, children will discover what invertebrates are, how they are classified, the role insects play in this group, and why they are essential for the balance of nature.

Natural Sciences in Primary School aim to help children understand the world around them by developing their curiosity and critical thinking through observation and experimentation. They learn about nature, living beings, the human body, energy and the environment, while also understanding the importance of caring for the planet.

This 3D animation explains the hormonal changes during the menstrual cycle. The menstrual cycle begins with menstrual bleeding, marking the follicular phase’s first day. When the follicular phase begins, levels of estrogen and progesterone are low. As a result, the top layers of the uterus’s thickened lining break down and are shed, and menstrual bleeding occurs.

About this time, the pituitary gland starts sending follicle-stimulating hormone to your ovaries, stimulating the development of 5 to 20 follicles in the ovaries. Each follicle contains an immature egg and produces estrogen. One follicle will soon begin to grow faster than others. This is called the dominant follicle. As the follicle grows, the levels of estrogen in the blood rise significantly. This increase in estrogen begins to inhibit the secretion of the follicle-stimulating hormone. The fall in follicle-stimulating hormone allows smaller follicles to die off. They are, in effect, "starved" of follicle-stimulating hormone.

The increasing amount of estrogen in your body also ensures that the lining of your womb thickens with nutrients and blood. This is so that if you do get pregnant, the fertilized egg will have everything it needs to grow.

The ovulatory phase begins with a rise in the levels of luteinizing hormone and follicle-stimulating hormone. The surge in the luteinizing hormone triggers one of the most prominent follicles to pop open and release its egg, which heads into the fallopian tube and starts its journey toward the uterus. Ovulation usually occurs 16 to 32 hours after the beginning of the surge, around day 14 of the menstrual cycle.

During the luteal phase, the levels of the luteinizing hormone and follicle-stimulating hormone decrease. The ruptured follicle closes after releasing the egg and forms a corpus luteum, which produces estrogen and progesterone, which cause the lining of the uterus to thicken even more. If an egg is fertilized, progesterone supports early pregnancy. But if no fertilization occurs, the corpus luteum will break down between 9 and 11 days after ovulation. This results in a drop in estrogen and progesterone levels, bringing us back to the first stage of menstruation if no pregnancy has occurred.

Biology MineralsIn this video I will discuss 15 important minerals of the human body. A mineral is an inorganic nutrient which means it lacks carbon. Minerals build cells, take part in chemical reactions, send nerve impulses, and carry oxygen. Your body cannot produce any of the minerals that it needs. Instead, you must get minerals from the foods you eat.
Minerals are one of the four groups of essential nutrients, the others of which are vitamins, essential fatty acids, and essential amino acids.
Macrominerals are used in large quantities
Trace minerals are used in very small amounts

The largest things in the universe are black holes. In contrast to things like planets or stars they have no physical size limit, and can literally grow endlessly. Although in reality specific things need to happen to create different kinds of black holes, from really tiny ones to the largest single things in the universe. So how do black holes grow and how large is the largest of them all?

This video provides examples showing the step by step process in adding dissimilar fractions.

In adding dissimilar fractions we need to change dissimilar fractions to similar fractions first before adding. To change dissimilar fractions to similar fractions get the LCD and divide it by the denominator then multiply the answer by the old numerator. The product is the new numerator. When the fractions are already similar fractions add the numerators and copy the LCD. Express the answer in lowest term.

Hold on to your butts. This episode is about… butts. The science and evolutionary history of your rear end, the down-low on your derriere, shining a little light where the sun don't shine… you get the picture.
