A child under bar mitzva or bat mitzva age also gets dressed the same way as an adult, except if less than 7 years old (consult a rabbi in that case).
 

Anyone in the household who has reached bar or bat mitzva age can light Chanuka candles, thereby fulfilling the halachic requirement that one candle per household per night must be lit.
 

At the Passover seder, all Jews above the age of bar mitzva or bat mitzva (including women--unlike on other Jewish festivals) must drink wine for kiddush and for the other three times in the seder when the borei pri ha'gafen blessing is said.

Attending a funeral is a mitzva--that of honoring the dead person--but in attending a parent's funeral, there is the added mitzva of honoring a parent.

Adult (at least bar mitzva or bat mitzva) offspring should attend their parent's funeral, unless there is a financial, health, or other significant reason not to attend. There is no requirement for minor offspring to attend a funeral for a parent. RMH recommends consulting a rabbi before having a minor go to any funeral, including for the child's parent.

NoteIf both parents are still alive, it is not customary to go to the cemetery for any funeral except for a close relative, but it is a mitzva to attend the eulogies and ceremony beforehand.

If you light the Chanuka menora in the synagogue on the first night of Chanuka, say she'hecheyanu in synagogue. When you go home, if you light only for yourself, do not say she'hecheyanu again. However, if you light for your wife or for any adults including children above the age of bar or bat mitzva, say she'hecheyanu again.

You may not turn off or disconnect an operating electrical device (such as an alarm, appliance, light, oven, or any machinery) on Shabbat, even using a shinui and even if the noise will prevent you from sleeping. You may ask a non-Jew to turn it off, but you may not ask a Jew, not even a child below bar/bat mitzva age.

We are required to eat two meals on Jewish festivals, each preceded by kiddush, one in the evening and one in the morning. For both meals for each Jewish festival day (and all three meals on Shabbat), say ha'motzi over two complete loaves of bread, each of which is at least 1.3 fl. oz. in volume.

Saying Jewish festival kiddush at the place where you will eat your meal is a rabbinical (d'rabanan) enactment.
Jewish Festival Kiddush-Meal Quantities: Evening

• For evening kiddush for a first-night (d'oraita) Jewish festival, a minimum of 4 fl. oz. (119 ml) of wine must be blessed on and at least half must be drunk.
• For evening kiddush for a second-night (d'rabanan) Jewish festival, a minimum of 3.3 fl. oz. (99 ml) of wine must be blessed on and at least 2.0 fl. oz. must be drunk.
• For the evening meal, as on the first two Shabbat meals and for all required Jewish festival meals, a minimum of 1.9 fl. oz. (56 ml) of bread must be eaten within four minutes.

Eating Requirements for Jewish Festival Morning Kiddush
There are two separate eating requirements during the daytime. They may be combined (say/hear kiddush and start the main meal right away) but are often done separately (say/hear kiddush and then eat some light foods and beverages; the main meal is eaten later in the day).
Note Since eating and drinking requirements on all morning kiddushes (both Shabbat and Jewish festivals) are d'rabanan, the required beverage amount for morning kiddush is only 3.3 fl. oz. (99 ml) instead of the d'oraita 4 fl. oz. (119 ml) (which is required for kiddushes for Shabbat evening and all first-night Jewish festivals).

• Morning kiddush requires a halachically legal “meal” with these elements:
  • Blessing on a minimum of 3.3 fl. oz. (99 ml) of wine (or other beverage),
  • Someone's drinking at least half the beverage, followed by
  • Eating at least 1.3 fl. oz. (39 ml, or 1/6 cup) of some type of mezonot within four minutes. 
    Note If you drink at least 3.3 fl. oz. (99 ml) of wine within 30 seconds, you do not need to eat mezonot.
    Note You do not need to drink the wine or other kiddush beverage to fulfill “establishing a meal.” You may hear kiddush and then simply eat the required amount of bread or mezonot. This applies to Shabbat or Jewish festivals, evening or morning.
     

 

• The real meal (kovei'a se'uda) requires eating at least 1.9 fl. oz. (56 ml) of bread (or matza during Passover!) within four minutes. It must include enough food to satiate. 
  Note You can simultaneously fulfill the requirement to “establish a meal” and to “eat a meal” by eating one (the same) piece of bread.

You may not use God's name unless there is a positive purpose. Anyone may say any of God's names anytime when studying Torah, even a girl or woman who is reading the Torah with cantillation/trop where she might need to repeat God's name or other words in a line/pasuk and thereby not say the entire pasuk as it is written.
It is permissible to use God's name (and not an altered name such as “Keil” or “Elokim”) in these cases:

• When reciting a sentence or phrase from the Torah.
• For any type of teaching of Torah, blessings, and prayers to children up to bar/bat mitzva age.
• In Shabbat songs/zmirot.
