Difficulty: Easy Supplies • A box (or a jar) • Small pieces of paper • Pen List of activities to do when the kids are bored, for example: • Kick a ball outside • Jump on the trampoline • Play Lego • Use only 12 Lego blocks and 4 wheels to make a vehicle • Play with playdough • Make a fort • Have a dance party • Make an obstacle course • Create a race track for the toy cars • Clean your room • Chalk drawing outside • Read a book • Draw something • Paint rocks • Write a letter to someone • Do a puzzle • Feed the birds • Play dress up • Jump rope • Try to do a handstand • Ride your bike for 30 minutes • Drink a glass of water • Play hopscotch • Finger painting • Draw with your left hand
Elephant toothpaste science experiment
The rather dramatic but controlled explosion is just good old regular foam. The foam bubbles are filled with oxygen. The yeast acts as a catalyst, which speeds up the reaction caused by the breakdown of oxygen from the hydrogen peroxide. Because it all happens so fast, it creates lots and lots of bubbles. It also makes an exothermic reaction, meaning it creates heat.
Egg in a bottle science experiment
This is a great science experiment to demonstrate the power of air pressure. The egg appears to be sucked into the bottle, however it's not being sucked at all. It's a matter of high pressure overcoming low pressure. Initially, the air pressure inside and outside the bottle is equal, preventing the egg from moving. When the paper burns inside the bottle, it heats the air, raising the temperature and, consequently, the pressure. Placing the egg on the bottle top creates a partial seal, allowing the high pressure to force air out of the bottle. Once the burning paper depletes the oxygen, the flame extinguishes, causing the temperature and the pressure inside the bottle to drop. Suddenly, the outside air pressure is higher than the inside pressure, and pop! The egg is pushed into the bottl
