Science: Food Chains

Today we are going to learn about food chains. All ecosystems need food chains for the natural habitat to survive. If the food chain is broken or changed it may severely damage the ecosystem.

We will now create a food chain in our science books. Your food chain must have the following:

– A producer (plant or grass)

– A primary consumer (usually a herbivore)

– A secondary consumer (usually a carnivore > sometimes there is more than one secondary consumer)

Your food chain will be a diagram that is labelled like the examples above.

Science: Day & Night

Today we are going to watch a video for science that explains why we have day and night. Watch very carefully and be ready to write a conclusion for why we have day and night.

You will now create a labelled diagram that shows how day and night exists.

 

Science: Sugar in soft drink and fruit juice

How Much Sugar is in Soda?So how much sugar is there really in that can of Coke or Pepsi you’re drinking? Probably a lot. Watch this science experiment video and see a few different ways you can find out the amount of sugar you’re drinking in your soda or fruit juice.

The answers might surprise you, luckily there’s always water as an alternative.

Science: The Digestive System

Today we are going to learn about what happens to the food we eat. When we put food into our mouths our body needs to break the food down, this happens in our digestive system.

Watch the clib below from The Magic School Bus and then we will explain in our science books what happens in our digestive system.

Science: A Chemical Reaction

3/4A were able to make a chemical reaction by using vinegar and bi-carb soda. We put the bi-carb soda into a balloon and put the balloon over the top of a bottle with some vinegar inside it. When the vinegar and bi-carb soda mixed it caused a chemical reaction, which released carbon dioxide. The carbon dioxide was then able to inflate the balloon.

The students also used this session to complete their first science report of the year.
