Science

Food chains, conductors and heat

An AR classroom game for Grade 4. Learners can aim with their hands at the camera or play by tapping the screen.

This set has 4 rounds in an interactive sorting activity.

Sample questions

A few real prompts from the game to help you choose an activity for your class.

01
Sort the living things into groups.
Sort into
- producer
- consumer
- grass
- a rabbit
- algae
- a fish
Read the explanation
Producers make their own food; consumers must eat something else.
02
Sort the animals by what they eat.
Sort into
- herbivore
- carnivore
- a cow
- a lion
- a rabbit
- a hawk
Read the explanation
Animals eat plants, meat, or both.
03
Sort the materials into groups.
Sort into
- conductor
- insulator
- copper
- rubber
- iron
- plastic
Read the explanation
A conductor lets current through; an insulator does not.

Game teaching guide

What children will practise

Sorts four distinctions: producer or consumer, herbivore or carnivore, conductor or insulator, and changes of state that take heat in or give it out. Two rounds are ecology and two are materials and heat, so the set is not tied to any single indicator; use it as a cross-unit review.

What's in the worksheet

4 questions, a sorting game with four items each - Grass and algae are producers; a rabbit and a fish are consumers - A cow and a rabbit are herbivores; a lion and a hawk are carnivores - Copper and iron are conductors; rubber and plastic are insulators - Ice melting and water boiling take heat in; water freezing and vapour condensing give heat out

How to use it in class

A cross-unit review, about 6-8 minutes in teams. Question 4 is the hardest: have children hold a cold glass with droplets forming and ask where the vapour's heat goes. After question 1, ask what the fish eats, to show that consumers eat producers. You can link it to a class and record it in the gradebook.

Common sticking points

- Question 4: putting vapour condensing with takes heat in, assuming every change of state needs heat. Show that the reverse direction gives heat out. - Question 4: putting water freezing with takes heat in, thinking cold is added. Rephrase: the water loses heat to the freezer. - Question 1: calling algae a consumer because it lives in water like fish. Stress that algae makes its own food with light.
