Pupil outcome: I can use -er and -ir verbs in the past (preterite) to understand and ask questions about past experiences of moving to live in another country. Key learning points: - Regular -er/-ir verbs: 1st, 2nd, 3rd person singular...

Pupil outcome: I can use irregular verbs in the preterite when talking about a school trip. Key learning points: - Knowing a word means you can understand it in listening and reading but also use it in speaking and writing. - Formation...

Plants absorb water from the soil using root hairs, and transport it through three main pathways: vacuolar, symplast, and apoplast. In the vacuolar pathway, water moves through vacuoles and plasmodesmata but faces high resistance. The...

This video has kids practice blending sounds sound by sound where they blend the first two sounds first, and then the next sounds. Many kids who struggle to blend words, especially those with blends, find this method helpful. This is...

We've taken a look at many nouns from the first and second declensions. Now let's dive into the third declension, which is a bit trickier. This declension is divided into two subgroups: parasyllabic and imparisyllabic nouns. What do...

Meet the young minds turning creative ideas into reality, proving that innovation has no age limit.

Ice flower is a nickname for a miniature sculpture of ice that forms on only a few kinds of plants, only when the air temperature is below freezing for much of the night, with calm wind, clear sky, and soil that is moist and not frozen....

Explore the fascinating physics behind Bernoulli’s Principle, which describes how fluid pressure changes with speed and height. In this video, we derive Bernoulli’s Equation step-by-step, breaking it down into simple, understandable...

In this video, we break down the derivation of the continuity equation for ideal fluid flow! Learn how the equation explains why fluid velocity increases as the cross-sectional area of a pipe decreases, such as when you narrow the end of...

Discover the fascinating interplay between buoyant force, Newton’s third law, and free body diagrams in this hands-on physics demonstration. We explore how forces interact when a steel or oak sphere displaces water in a beaker on a...

In this video, I break down Rotational Kinematics, the first part of Unit 5 for AP Physics 1. From angular displacement to centripetal acceleration, we cover key concepts crucial for mastering rotational motion. You'll learn about key...

Curious about rotational kinematics? In this video, we break down key concepts like angular displacement, velocity, and acceleration, using simple demonstrations. Perfect for AP Physics 1 students or anyone looking to understand...

Discover how buoyant force impacts scale readings in this engaging physics lesson. Using free body diagrams and Newton's laws, we analyze scenarios involving submerged objects, tension forces, and buoyant forces. Watch as we break down...

Dive into the fascinating world of fluid flow with this introduction to the four conditions of ideal fluid flow: nonviscous, incompressible, steady, and irrotational. Learn how these principles simplify the complex motions of fluids and...

Learn how the speed of an ideal fluid changes when it flows through a pipe with varying cross-sectional areas. In this fun and engaging video, we apply the continuity equation for volumetric flow rate and solve a problem step-by-step....

Learn how to calculate the buoyant force acting on a steel sphere submerged in water! This demonstration covers the physics behind buoyant force, free body diagrams, and Newton’s Third Law. We'll use measurements and calculations to show...

PALM ISLAND SINCE ANCIENT TIMES THERE HAVE BEEN SEVEN WONDERS OF THE WORLD BUT IF THE MARKETING HYPE IS TO BE BELIEVED THE EIGHTH WONDER HAS ARRIVED, DUBAI’S PALM ISLAND PROJECT. AND THERE’S NO DOUBTING THE WORLD'S LARGEST LAND...

In this video, the teacher explains the unique characteristics of cacti, including their spines that serve as modified leaves and their ability to retain water in the desert. The video also dispels the misconception that cacti contain...

Build a rubber band-powered car in this fun engineering challenge!

In this fun engineering challenge, your students will build rubber band-powered cars using the engineering design process and compete to see how far they can go.

OCD is more than just cleanliness and order. In this video, we uncover some lesser-known OCD obsessions that can disrupt daily life. From Harm OCD to Relationship and Somatic obsessions, We discuss the origins of these surprising...

Fresh water issues are getting harder to ignore. In the next five years, half the world’s population will live in a water-stressed area. Drought-stricken cities like San Francisco have started requiring large commercial building to...

In this experiment, find out if it is possible to grow bean sprouts in the dark, without soil!
