Students use two different methods to determine the densities of a variety of materials and objects. The first method involves direct measurement of the volumes of objects that have simple geometric shapes. The second is the water displacement method, used to determine the volumes of irregularly shaped objects. After the densities are determined, students create x-y scatter graphs of mass versus volume, which reveal that objects with densities less than water (floaters) lie above the graph's diagonal (representing the density of water), and those with densities greater than water (sinkers) lie below the diagonal.

Students are introduced to Newton's third law of motion: For every action, there is an equal and opposite reaction. They practice identifying action-reaction force pairs for a variety of real-world examples, and draw and explain simplified free-body diagram vectors (arrows) of force, velocity and acceleration for them. They also learn that engineers apply Newton's third law and an understanding of reaction forces when designing a wide range of creations, from rockets and aircraft to door knobs, rifles and medicine delivery systems. This lesson is the third in a series of three lessons intended to be taught prior to a culminating associated activity to complete the unit.

Hello friends! Welcome to a new Happy Learning video.
Did you know, that for every four animals in the wild, three of them are insects? We calculate that for every human being, there are 200 million insects… We are surrounded by insects, so I think it’s important to to get to know them a little more.

Insects are invertebrate animals that have a share a number of characteristics:
Their body is divided into: head, thorax and abdomen, they have two antennae, six legs and they breathe through their traquea.

From the moment they are born, insects undergo a series of body changes called metamorphoses. Most insects are oviparous, and maggots are born from the eggs. As you can see in the images, they don’t look anything like their parents, they look like worms.
When they grow, they enclose themselves in a cocoon they make with a substance called silk. Inside the cocoon, they undergo an incredible change in their bodies and they exit as adult insects. This metamorphosis stage is called pupa, although when referring to butterflies we also call it chrysalis. This type of metamorphosis happens for 80% of the insects.

The large majority of insects have wings, in fact, they are the only group of invertebrates that can fly.

Another shared characteristic amongst insects is that they have almost perfect vision. They have compound eyes, it’s as if they had hundreds of tiny eyes in each eye, which provides excellent peripheral vision.

As we said before, there are so many insects, and there are also maaany types:
There are very annoying insects, like head lice, flies or mosquitos, interesting insects because of their shape, like stick insects, or leaf insects. Beautiful ones like butterflies or dragonflies, or singer insects like a grasshopper or cricket, that besides from singing is an excellent jumper! But… Do you know my favorite insect? It’s a bee! Because i love the honey they make!

Some insects, like ants or bees, live in highly organised societies, where they each have a job assigned. The Queen ant, for example, is in charge of laying eggs, drone ants protect the nest and worker ants are in charge of getting food and taking care of maggots.

The truth is, insects are incredible and although by their size they might seem unimportant, they are fundamental for nature’s balance. For example, they are in charge, along with some birdies, of pollination. Some insects, like my beloved bees, are constantly flying from flower to flower, transporting pollen from one flower to the next, fertilising them, which makes new amazing plants, come to life!

The truth is most insects, like most living things, are marvelous. Don’t you think?

What are you waiting for? Hi kids, today we are going to meet the bear, a very special mammal, who is very cute.
As you can see in the video the majority of bears have a very big and chubby body, with short legs and a long snout.
Like most mammals, its body is covered in hair. A bear’s fur can vary a lot in colour. It can go from snow white like a polar bear, to Brown like this grizzly bear, or to White and black like these friendly panda bears.

Although bears are very heavy and big animals, they are very capable of climbing trees with a lot of agility, however this is not always the case. They are also very competent swimmers.

Bears are omnivorous animals; they eat meat and vegetables, like us humans, however they are much greedier. The panda bear, for example, spends twelve hours a day eating bamboo and we all know how much the majority of bears love honey. To obtain most of the food they eat, they use their very developed sense of smell, it’s even better than a dogs.
There is a very special characteristic that bears have that converts them into a very interesting animal.
When the cold arrives in the freezing winter the majority of bears hibernate. They spend every day sleeping, they don’t wake up, they don’t eat, they don’t sleep, they dot drink and they don’t even poo… They live of the fat they accumulated during spring, summer and autumn. That is why they are so greedy, because they have to eat enough during these seasons, so that they can sleep all Winter.
Like all mammals, bears are viviparous, that is to say they are born form their mothers womb and the baby bears are also born without hair, teeth and are blind.
Bears are hunted for their fur, as coats and carpets can be made from them, and this is why they are in danger of extinction. If we don’t take care of them they can completely disappear from the face of the earth or they would only be able to remain in zoos.

An ability that bears have that always catches everyone’s attention is that they can stand on their back legs. This can be a very terrifying show as they can appear huge when they do so.
The most common bear is the grizzly bear; they can measure up to approximately three meters and weigh about 1477 pounds. It’s a lot, isn’t it?
Well know you now a bit more a bout bears, and even though they are not very lovable, they are super interesting!
