Maths Lab + GeoGebra Training Day 5 by Try For Learn, GeoGebra session by Try For Learn Team

During a power failure, or when we go outside at night, we grab a flashlight so we can find our way. What happens inside a flashlight that makes the bulb light up? Why do we need a switch to turn on a flashlight? Have you ever noticed that for the flashlight to work you must orient the batteries a certain way as you insert them into the casing? Many people do not know that a flashlight is a simple series circuit. In this hands-on activity, students build this everyday household item and design their own operating series circuit flashlights.

In this hands-on activity, students explore the phenomenon of static electricity by engaging in the science and engineering practices of asking questions and planning and carrying out investigations. Students enact a “human diagram” to model the Bohr model of an atom. Then, in pairs, they charge a comb (on hair) and use it to attract an O-shaped piece of cereal and then watch the cereal jump away when it touches the comb. They do the same with Styrofoam pellets, observing them pulling towards a charged comb, then leaping back to the table. Through these investigations, students explore the disciplinary core ideas of electric and magnetic forces, the crosscutting concept of cause and effect, and they make sense of static electricity and what’s going on at the atomic level.

Hello Happy friends! Are you ready to learn?I’m Sarah, and today, I want to talk to you about animals that disappeared from Earth a long time ago, exactly 65 million years ago!Do you know what animals I’m talking about?Well done! Today, we’re going to learn about why the dinosaurs vanished from Earth! The word Dinosaur means Terrible lizard.But… Not all dinosaurs looked like lizards, and not all were terrible!Actually, did you know that some of them used to fly, and had feathers?They looked similar to birds, rather than lizards! Look! Like this one! Dinosaurs, lived on earth for 150 million years, and they left many footprints behind.But… We still don’t know why they disappeared.
There are various theories, but the one supported by most scientists, and the most believable one, is…. the meteorite theory!Apparently, a great asteroid hit the Earth, and created a huge explosion.
This great explosion, made the climate on Earth undergo dramatic changes. It changed from humid and warm, to cold, and very dry.
This climate change caused by the meteorite, destroyed all the dinosaurs in our planet.But, fortunately, it didn’t terminate all animal species that were there at the time.

Do you know some of the animals that saved their lives?For example, birds and crocodiles! I think it’s so cool, because I love birds… Although… I’m not such a big fan of crocodiles, because I’m a little scared of them.Oh-oh, there’s one coming here! I’m leaving!!!Goodbye Happy Friends,I hope you’re always ready to learn! Bye!

Estuaries are bodies of water in which salt and fresh water mix.
Estuaries have been called the "nurseries of the seas because they provide a safe area for fish, birds, and other animals to raise their young.

Estuaries can be classified based on their geographical features. The four main types include bar-built , coastal plain, tectonic esturary, and
fjord type estuary.
