What is Sense?
Sense is an interaction between a stimulus and a response. For example- Have you ever touched a hot vessel? what happens then?
Do you know the different types of senses?
They are sight, hearing, Touch, Taste and smell. Do you know that animals have stronger senses than us?
For example- Have you seen a shoot up the ears when you walk past it, have you seen ants moving in a straight line.
How they could see from hundreds of meters height. because Eagles, vultures can see four times further than we can. if you can see after two meters away. then they can see up to eight meters.
Why do the dogs shoot up its ears when you walk past it?
The dogs hearing is very sharp therefore it can hear you even if he is sleeping so for a hearing is its super sense.
What about the mosquitoes? how could the mosquitoes find you? sometimes it manages to sneak into your blanket – how does it know you are there?
A can smell you. they can find you by the smell of your body, the soles of your feet So, for a smell is its super sense.
Introduction to "Is Matter Around Us Pure?
Matter, the fundamental constituent of the universe, manifests in diverse forms, each characterized by its composition and properties. The quest to comprehend the purity of matter has been a perennial pursuit, driven by the intrinsic desire to discern the true essence of substances that populate our surroundings.
At its core, the inquiry into the purity of matter beckons us to contemplate the integrity and homogeneity of substances encountered in our everyday lives. From the water we drink to the air we breathe, the quest for purity underscores our interactions with the material world.
The exploration of purity necessitates a nuanced understanding of the classification of matter. Pure substances stand in stark contrast to mixtures, embodying uniformity and consistency in their composition. Elements and compounds, the elemental constituents of pure substances, exhibit distinct properties that define their identity and purity.
As we embark on this journey to unravel the purity of matter, we confront a myriad of questions and challenges. How do we discern the purity of substances amidst the complexities of their compositions? What methodologies and techniques enable us to isolate and purify substances from impurities that may compromise their integrity?
Throughout our exploration, we shall delve into the methodologies employed to ascertain and ensure the purity of substances. From the time-honored techniques of distillation and crystallization to the modern marvels of chromatography and spectroscopy, a panoply of methods awaits our scrutiny, each offering unique insights into the purity of matter.
Furthermore, our quest for purity extends beyond the confines of the laboratory, permeating various facets of human endeavor. From pharmaceuticals to food production, the pursuit of purity assumes paramount importance, safeguarding human health and ensuring the quality and efficacy of products consumed worldwide.
In essence, "Is Matter Around Us Pure?" beckons us to embark on a journey of exploration and discovery, unveiling the intricacies of matter and the purity that lies therein. Through meticulous inquiry and empirical investigation, we strive to unravel the mysteries that shroud the purity of substances, illuminating the path towards a deeper understanding of the material world that envelops us.

Eleverna bygger sin termos för att förstå att luft isolerar.
Eleverna måste ha lärt grunderna om luft. Vad är luft? Var finns luft? Hur rör sig molekylerna beroende på temperatur.
ÅK 5 och 6 arbetar med grundläggande fakta om elektricitet och magnetism. Denna lokala pedagogiska planeringen innehåller även matriser, prov och fakta.
3. LEDDJUR
1. kräftdjur,
2. spindeldjur,
3. mångfotingar
4. insekter
Hudskelett och ledande ben och fötter förutom under
larvstadiet.
Har ett yttre skelett som består av kalk eller kitin.
Kroppen är huvud, framkropp och bakkropp med
ledande ben.
Leddjur är kallblodiga.

6. INSEKTER
Insekterna är den största djurgruppen vi har här på jorden.
Det finns drygt en miljon beskrivna arter insekter (fast
kanske femtio miljoner arter).
Man känner lättast igen en insekt på att den har sex ben.
Insekternas som bor på land har ofta trakéer, luftrör som
förgrenar sig i hela kroppen och transporterar syre och
koldioxid mellan den omgivande luften och djurens celler.
Blodet är färglöst, gult- eller grönfärgat
En del är växtätare, andra är rovdjur eller parasiter och vissa
är allätare.
11. ÖGON
Ett fasettöga hos en insekt. Notera att fasetterna är
sexkantiga och inte kvadratiska som hos räkor och
kräftor.
http://www.djur.cob.lu.se/Svar/Fasettogon.html
13. ÖGON
Huvudet hos en geting, sett ovanifrån. Upptill ser man
antennernas underdelar, på sidorna de båda
fasettögonen och mitt på huvudet de tre
punktögonen.
14. INSEKTENS SINNEN
Insekter ser, hör, känner doft och har känsel - men på
helt andra sätt än vi. För varje sinne finns en stort
antal sinnrikt utformade organ.

Ofullständig förvandling Fullständig förvandling
16. INSEKTEN BLIR TILL - LARV
Larven utvecklas i ägget, och kan efter ett par, tre
veckor äta sig ur ägget. Det primära är nu att växa.
Larvens hud växer eller tänjs inte efterhand som
larven blir större. Därför måste den byta hud flera
gånger, ömsa. Oftast ömsar den tre till fyra, innan den
är fullvuxen.
http://www.nrm.se/faktaomnaturenochrymden/djur/insekterochspindeldjur/larver.66.html
När larven ömsat hud för sista gången övergår den i
puppstadiet
17. ÄTA INSEKTER
Världens befolkning växer i snabb takt och i framtiden kommer vi ha svårt att få
maten att räcka till, om vi fortsätter att äta på det sätt vi gör. En lösning på det här
problemet skulle kunna vara attäta mindre kött och mer insekter.
En stor del av världens befolkning äter redan insekter och fördelarna är många:
Det är nyttigare än kött. Det finns nästan 2000 ätbara insektsarter och många är
sprängfyllda med protein, kalcium, fiber järn och zink. En liten portion gräshoppor
kan t.ex. innehålla samma mängd protein som en köttbit i samma storlek, men
med mycket mindre fett och färre kalorier.
Att föda upp insekter är billigt eller gratis och det krävs väldigt lite teknisk
utrustning. Att föda upp insekter kunde bli ett levebröd för många av världens
fattigaste människor.
Insekter är en mer hållbar matkälla än boskap. Boskap står för nästan en
femtedel av världens utsläpp av växthusgaser, mer än vad transporter står för.
Insekter å andra sidan producerar väldigt lite växthusgaser och att föda upp dom
kräver mycket mindre mark och vatten. Plus att de äter nästan vad som helst.
