Try some of these. Make sure you get an adult to help you.
Experiment 1 - Grow a carrot plant
Cut the top off a carrot leaving about 2cm of the orange part. Press the carrot piece into damp sand or soil in a saucer or bowl. Soon pretty leaves could appear and you will have a nice plant to keep at a window in bright light. The carrot will not regrow but if there is enough of the root left, it is possible to plant it and get some leaves from it.
Experiment 2 - Get to the
root
What You
Need:
3 Carrots; Sharp knife; Cutting board; Glass; Water; Red food colouring
What You Do:
1. Fill a glass half full with water.
2. Cut the end tip off of a carrot. Ask an adult to help you!
3. Add 10 drops of food colouring to the water.
4. Put the carrot in the glass of water.
5. Put the glass near a window that lets in sunshine.
6. Wait for a few days.
After a few days, put the carrot on the cutting board and with the help of an adult, cut the carrot in half. Look inside. You will see red colouring in the tubes of the carrot that go from the bottom to the top of it. This shows you that water was being absorbed by the bottom or tip of the carrot and travelling up the inside of the carrot. This is how plants and trees get water from their roots.
Experiment 3 - Carrot Magic
Perform a little science magic with this simple experiment. You will need a large bowl of water, a carrot and an apple. First, ask a friend what they think will happen when an apple or a carrot is put in the bowl. Place the carrot in the bowl first; then remove it and place the apple in the bowl.
What happens? Why?
Foods like carrots and apples have different amounts of air in them. Carrots are packed very tightly and are very heavy, making them sink. The apple is not packed as tightly and has many air spaces, which allow it to float.
Try slicing the apple and carrot to look closer.
