What Do You Hear in a Seashell?

Have you ever put a seashell up to your ear and heard a roaring sound the sounds sort of like the ocean? Is it magic? No! It's science! Jessi and Squeaks explain what's up!

Sound on the Move

“Sound on the Move” explores how sound waves travel different distances depending on the type of material through which they travel.

Make Sprinkles Vibrate with Sound

You might know that sound is caused by vibrations, but did you know that sound can also make things vibrate? You might have noticed this if you have ever been at a concert or in a car with the stereo booming. Sometimes the sounds are so loud that you can <i>feel</i> the vibrations! However, sounds that loud can damage your hearing, so in this project you will investigate them using something safer.

What is Sound?

Learn all about how sound works with Jessi and Squeaks on SciShow Kids!

Let's Explore Caves! | SciShow Kids Compilation

Squeaks, Jessi and Anthony are spending a bunch of time learning all about the wonders of caves in this compilation video!

Waves: Reflection

This video explores the characteristics of waves. It explains the speed of waves, how this value is calculated and the four basic interaction between waves. Other terminology includes: vibration, crest, trough, amplitude, wavelength, frequency, reflection, refraction, diffraction, interference; and mechanical, electromagnetic, transverse, surface, and longitudinal waves.

Light

Using real world demonstrations and colorful graphics, Real World Science: Light teaches students the different properties of light, pertinent definitions and how light travels. Students will learn how different mediums can affect light, resulting in reflection, refraction and absorption, and they will explore the color spectrum using prisms and paints.

Glowing Ocean Animals!

Jessi and Squeaks discover some amazing ocean creatures, ones that glow by themselves!

Support them to understand more about life and the Earth with these interactive and immersive video lessons. Explore questions together such as ‘Why does the moon change?’ and ‘How do snakes smell with their tongue?’

Why Do Animals Have Whiskers? | Amazing Animal Senses | SciShow Kids

Squeaks and Mister Brown are learning about senses! Did you know that animals that have whiskers can use them to sense things?First Grade Next Generation Science StandardsCrosscutting Concept: Structure and Function: The way an object is shaped or structured determines many of its properties and functions.Disciplinary Core Ideas:LS1.A: Structure and Function - All organisms have external parts. Different animals use their body parts in different ways to see, hear, grasp objects, protect themselves, move from place to place, and seek, find, and take in food, water and air. Plants also have different parts (roots, stems, leaves, flowers, fruits) that help them survive and grow (1-LS1-1).LS1.D: Information Processing - Animals have body parts that capture and convey different kinds of information needed for growth and survival. Animals respond to these inputs with behaviors that help them survive. Plants also respond to some external inputs (1-LS1-1).Performance Expectation:1-LS1-1. Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs.

Why Do Birds Sing? Animal Science for Kids

It's spring where Jessi and Squeaks lives, and that means the air is filled with the sounds of birds singing! But have you ever wondered why birds sing and who they're signing to? 

Heredity: Introduction

This program introduces the idea of the inheritance of traits. Attention is given to some of the fascinating features which are heredity-based not only in humans, but also in other plants and animals. The work of the father of modern genetics, Gregor Mendel, is outlined. The inheritance of certain recessive and dominant traits is explored. Other terminology includes: traits, inheritance, genes, dominant, and recessive.

Variation

CREDITSAnimation & Design: Waldi ApollisNarration: Dale BennettScript: Lucy BillingsLook at these baby animals. You will have immediately observed how cute and fluffy they are but you willalso have noticed that they are different - they vary. Yes - some are puppies and some are kittens.There is a great deal of variation between species but also there is variation within a species. Onepuppy is fluffier than the other, they have different colour fur and the kittens have different coloured eyes.Variation is the differences in the characteristics of individuals in a population. It can be due to genetics,the environment or a combination of both.Let’s start with genetics. Different members of a population have different DNA, unless they are identicaltwins. This means they have different versions of genes, called alleles, and these alleles give rise todifferent characteristics.For example, on the eye colour gene this kitten has an allele for blue eye colour whereas this kitten hasan allele for brown eye colour.If the species reproduces by sexual reproduction, the random mixing of alleles from both parents resultsin extensive genetic variation within a population of a species. This means that some individuals arebetter adapted to their environment than others, allowing natural selection to take place. For example, ina population of rats, some will have better eyesight than others. These will be able to avoid being eatenby predators so are more likely to survive to reproduce and pass on this advantage to their offspring. Ifyou want to learn more about natural selection, watch this video. Some examples of variation in humans that are controlled only by genes include eye colour and bloodgroup. If you have blood group A it is because you have the alleles for this characteristic. This is geneticvariation, and it is something that you were born with, and nothing can change it.Some variation is due to the environment, or lifestyle of the organisms. Examples in humans are hairlength (it depends on how short you decide to cut it), your accent, as this is linked to where you live andif you have any piercings, tattoos or scars. These are characteristics that you acquire throughout yourlife.Many characteristics are due to a combination of both genetics and the environment. For example, theheight a person can grow to is determined by genetics - tall parents tend to produce tall children.However, a person will not grow to their potential height unless they eat a healthy, balanced diet. Also,there is some debate on how much intelligence is due to genetics or the quality of education a personreceives - is intelligence more due to nature or nurture?To answer these questions scientists can do experiments using identical twins. If the characteristic inboth twins is the same then it is most likely due to genetics. If it is different, then the environment hasplayed an important role. For example, identical twins will have the same eye colour as this is only due togenetics but they will have different personalities, talents, likes and dislikes and this shows that these arealso influenced by the environment.So, in this video we learnt about variation, and how it can be controlled by genetics, the environment orsometimes both.

Understanding Earth's Seasons

Planets Set:              6. This clip explains  the role of the Earth's rotational axis in creating the seasons of the year.

Weather and Seasons: seasons and dressing for seasons

A little girl and her grandfather spend a summer afternoon sitting by a pond. The conversation changes from how warm the summer day is to how the pond gets cold and freezes in the winter. The grandfather helps the girl understand how the sun controls temperature and the seasons while the girl describes how to dress for different weather and seasons. Both discuss how meteorologists predict weather using weather instruments, and how those predictions help people live comfortably. They conclude that all weather has a purpose and can be appreciated and enjoyed if we are prepared for it.
