Coffee and Tea Painting
Concept: Tea and Coffee stains because of the chemical-tannin. Lemon juice can help to bleach.
Activity: Make a little of thick tea and paint a crocodile’s body with it. Then, make a little bit of coffee and use it to draw the details or decorate the crocodile. Finally, use lemon juice to bleach and make some parts of the crocodile lighter.
Observation: Coffee stains more than tea and lemon juice makes the colour of the coffee/tea lighter.
Conclusion: Coffee contains more tannin than tea. And next time, you can always use lemon juice to remove coffee or tea stains on your shirt.
Concept: The human eyes can store a picture for a few seconds after seeing it.
Activity: Making a spinner. Cut 2 squares and draw a fish tank on one of the square and a fish on another square.
Then tape 2 straws and pieces of thread behind the picture and glue the picture of a fish tank onto the back of the upside-down fish.
Then twist the thread tight and finally letting it go and you will see the fish in the tank as the picture spins.
Activity 1-3 are ideas taken from an activity book.
Concept: Solid and liquid.
Activity: Making our own slime -Is slime solid or liquid??
Ingredient: Cornflour, cold water and a few drops of food dye.
Just mix them all together until you get the slime effect.
Observation: Emmanuel realised that slime feels solid when he squeezes it but it flows out of his hands when he just hold it on his palm.
Conclusion: He says that slime is both a solid and liquid.
Emmanuel just likes to observe how the slime flows through his fingers. Highlight to the child that liquid flows.
Faith ( 8 months old) is trying to squeeze the slime and she realized that it is hard and solid.
This slime is baby safe too.
It's not messy and easy to clean up as the slime will turn into flour when it dries up and all you need to do just add more cold water.
Concept: soluble or insoluble, solution or mixture.
Things you need: some salt crystals, sand and anything you can find in your kitchen. Paper towels can be used as filter paper too.
