Short-term memory activity

You will need: A friend or family member to test, some paper and a pencil.

Explain to your friend or family member that you are going to read out a list of ten words and they need to try to remember the list of words, in order, without writing them down.

Read out this list of words (or make up your own list of ten words):
Apple, Monkey, Pencil, Bike, Clock, Cake, Tractor, Oven, Shoe, Tree

Challenge your friend or family member to write down the words in order. If they have any trouble writing or spelling the words, they can draw pictures instead.

How many words did they remember?

 

What’s happening?

This activity tests short-term memory and there is a limit to the number of words people can remember. For most people, the limit is between 6 and 8 words. If someone was to do this activity over and over again, they would probably get better at remembering the list of words, until they could write all ten words correctly. After enough practice, the list of words might even stay in their long-term memory.

Learning is an active process that takes some effort and it usually involves using our past experiences to make sense of new information. If someone needed to learn the list of ten words (for some strange reason) they could try using those words to write a story or maybe come up with a pattern or a poem to help them remember the order of the words. Doing this would help use their existing knowledge of what the words mean to make some sort of sense of an otherwise random order of the words.

It’s time to get to work with five fun and fascinating fast facts about energy, an interview with Lee Constable, a presenter and author of books about sustainability, and an energy transformation activity for you to try yourself at home.

Energy transformation activity

You will need: an object you can drop, such as a ball or a rolled-up pair of socks, and a rubber band.

Energy cannot be created nor destroyed. This is called the ‘Law of Conservation of Energy’. However, energy can change into different forms. How many energy transformations can you observe in about a minute?

Rub your hands together as fast as you can. You are turning moving energy into heat energy, with help from the force of friction.

Hold the ball or socks high above the floor. What you are holding now has gravitational potential energy, otherwise known as stored energy, let go and the gravitational potential energy turns into moving energy as the object falls to the floor, because of the force of gravity.

Feel the rubber band and notice if it feels cold or hot. Use both hands to stretch out the rubber band over and over again for a few seconds and then feel if the rubber band has heated up. If it has, some of the moving energy has turned into heat energy.

Stretch out the rubber band again so it has lots of stored elastic energy and then aim the rubber band away from you and anyone who is with you. Let go, so the rubber band flings through the air, turning the elastic energy into moving energy.

Look around you and see what other energy transformations you can see, for example, turning on a light.

It’s time for a heart-to-heart with five fun and fascinating fast facts about blood, an interview with Dr Patrick Capon, a science communicator who knows a lot about blood, and a heart pumping activity for you to try yourself at home.

12:34 Heart rate activity

 

Australian Redcross Lifeblood: https://www.lifeblood.com.au 

 

Heart rate activity

You will need something that can measure 30 seconds, for example a clock with a second hand, a stopwatch, or the timer on a smartphone.

Feel the pulse in your wrist by holding two fingers gently on the inside of your wrist. If you can’t feel the pulse, change the position of your fingers and rest them gently until you feel the pulse.

The pulse beats in time with your heart pumping blood around your body, so it can be used to measure your heart rate.

Set the timer to measure 30 seconds and count the number of beats you feel in 30 seconds. If you double this number, that number is your heart rate in ‘beats per minute’. For example, if you count 40 beats in 30 seconds, your heart rate is 80 beats per minute.

Do some energetic exercise, like star jumps or running around, for about one minute.

Find your pulse again, set the timer for 30 seconds, and count the number of beats you feel in 30 seconds. Double this number and you will probably have a higher heart rate this time.

When you exercise, your muscles use more oxygen. A faster heart rate means the blood moves faster around your body and more oxygen can be delivered to your muscles.

Let’s go with the flow with five fun and fascinating fast facts about water, an interview with Kelly Osterberg, an educator who knows a lot about water catchments, and a watery activity for you to try yourself at home.

Water from leaves activity

You will need: a large clear plastic bag, some string, and a healthy tree with lots of leaves that is in a sunny place.  

Choose a leafy branch hanging down low and bending towards the ground.

Place the plastic bag over the branch so there are lots of leaves inside the bag.

Gather the edges of the bag and hold the edges firmly around the branch. Tie some string around the bag to hold it in place on the branch. Try to position the bag so water will collect in the bottom of the bag without leaking out.

Leave the bag in place for several hours or overnight. After a few hours, you should start to see water collecting in the bottom of the bag.

What’s happening?

The water vapour made by the leaves condenses on the inside of the plastic bag to form liquid water which then flows down and collects at the bottom of the bag. This method for collecting the ‘transpiration’ water from plants is a bush survival skill people can use if they are stranded in the bush with no fresh water to drink, however, you should not drink the water you collected in this activity because it might not be very clean. Maybe you can pour the water back around the bottom of the tree so the roots can soak it up for more transpiration.

Let’s celebrate World Frog Day with five fun and fascinating fast facts about frogs, a chat with some froggy scientists, Dr Jodi Rowley and Dr Rebecca Webb, and a gooey chia seed frog spawn activity for you to try yourself at home.

Chia seed frog spawn activity

You will need: cold water, a measuring cup, a tablespoon, 2 tablespoons of black chia seeds, and a spoon for stirring. Chia seeds are small seeds that you might be able to buy at a supermarket, a fruit and vegetable shop, or a health food store.

Wash your hands with soap and warm water.

Add half a cup of cold water to the measuring cup.

Add two tablespoons of black chia seeds to the water.

Stir the mixture and leave it to sit for about 5 minutes.

Stir it again and then leave the mixture to cool down in the fridge for 2 hours.

After 2 hours, take it out of the fridge and stir the mixture one more time.

Make sure your hands are clean before picking up the mixture to play with it.

When you take it out of the fridge, you will have a cup of gooey chia seed frog spawn.

You can also try adding honey or maple syrup to the chia seed mixture to make a tasty snack!

 

What’s happening?

Chia seeds are the seeds of the plant Salvia hispanica which is native to Mexico and Guatemala. When the seeds are mixed with water, a slimy coating forms to protect the seeds until they have time to grow. The slimy coating on the seeds looks a lot like the gooey jelly in frog spawn that protects frog’s eggs until they are ready to hatch.
